title A Thousand BIM: A rapid value-simulation approach to developing a BIM tool for supporting collaboration during schematic design
source International Journal of Architectural Computing vol. 12 - no. 1, 47-60
summary The purpose of this study is to develop a BIM-based plug-in that is able to assist a collaboration among heterogeneous professionals. The tool will enable them to communicate in the same language, articulate criteria and priorities in multiple perspectives, and to share rapidly simulated evaluations of schematic design variations. Among many barriers that block collaborations among professionals, a quintessential barrier in the building and design industries may be epistemological rather than physical. The professionally different ways of thinking, expertise, values, and priorities can be a block on the collaborative development process of architectural design projects. This paper takes the example of the relationship between developers and architects, who tend to have different evaluation criteria. A real-time value simulation tool is introduced as a means to generate possible building typologies on a given project site, with computation of expected total values expressed in simple financial terms.

title A Thousand BIM – A Rapid Value-Simulation Approach to Developing a BIM Tool for Supporting Collaboration During Schematic Design
source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 23-32
summary A typical architectural design project proceeds as collaboration among professionals who have different expertise, values and priorities. The collaboration is needed to make designs both rich yet feasible, but the professionally different ways of thinking can also be a block on the way of design development. This paper takes the example of the relationship between developers and architects, who tend to have different evaluation criteria, methods, and processes. A BIM-based tool, A Thousand BIM, is introduced as a means to quickly generate possible building typologies on a given project site, with computation of expected total values expressed in simple financial terms. Its aim is to help a group of heterogeneous professionals to communicate in the same language, articulate criteria and priorities in multiple perspectives, and share rapidly simulated evaluations of schematic design variations. The implemented evaluation process considers construction cost per square foot, land value, and sustainability as well as other soft design values such as views and accessibility. It can take various market data as inputs to cost calculation, and the weight to each of the design values is dynamically adjustable. A professional can explicitly set them, and share the criteria, priorities, and results of value simulations with others in an enhanced collaborative process.

title Parametric Design Process of a Complex Building In Practice Using Programmed Code As Master Model
source International Journal of Architectural Computing vol. 8 - no. 3, pp. 359-376
summary Parameter based design explorations inevitably require a unified master model that represents the current design state, where each parameter being explored is essentially a critical sub-case of this master model. Throughout the constantly changing design state, it is beneficial to maintain a master model that is flexible and adaptive. This paper describes the design process of a complex building whose master model documented the design logic through implementation of software code. This process is illustrated by the case study of Lotte Super Tower (Seoul, Korea) from the beginning of schematic design to end of construction document phase. By maintaining the master model as a platform-free software code, in contrast to platform-dependent methods, the case study illuminates the advantages of documenting the generative logic behind design variations in a way that allows greater flexibility and a higher level of alignment with design intent.

title Text, Model, Image, the Inconsistent Cycle of Reflective Design in Architectural Speculation
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The paper will examine the sites of imaginal or creative 'events' set within the discourse of architecture and landscape design. It will discuss the cognitive and reflective actions implicit in creating or opening up the spaces of thinking in design. Notions of 'linearity' and 'intuition' in the emergence of discursive design work will be tested with reference to the textual work of Barthes, Foucault and Baudrillard, and to the imaginal work of Lebbeus Woods, Piranesi and Daniel Liebeskind. The potential for relocating terms and collapsing conventional disciplinary boundaries to discover a creative field of discourse within architectural design will be discussed, together with the specific tactics and strategies which may be employed by the designer to achieve such a collision in the problematizing of a design project. Ideas of reality, simulation and materiality will be discussed in the context of the designer's external frames of reference (societal, ecological, political, aesthetic, cultural) and their possible relationship with the cognitive process in order to discover the terms under which an architectural discourse seeks validation.

title Potential Use of Structural Layout Optimization at the Conceptual Design Stage
source International Journal of Architectural Computing vol. 10 - no. 1, 13-32
summary Despite recent developments in computer-aided design in architecture, both in terms of form generation techniques and performance-based design tools, there still appears to be polarization between the ‘visual’ and the ‘technical’ elements of design. Two causes of this are discussed: long-standing tradition within the discipline and perception of design as primarily a visual exercise. Structural layout optimization is a technique which enables automatic identification of optimal arrangements of structural elements in frames. As the technique appears to have the potential to help reduce the polarization between the visual and the technical elements of design, it can be considered as an ‘integrative’ form generation tool. Applications of the technique are considered via three design examples, demonstrating both its potential and areas where refinement is required before it is suitable for application in practice.

title Qualitative representation and reasoning about shapes
source Gero, J.S. and Tversky, B. (Eds.), Visual and Spatial Reasoning in Design , Key Centre of Design Computing and Cognition, University of Sydney, Sydney, Australia, pp. 55-68
summary In this paper we present an approach to the qualitative representation of shape and its use. We use a qualitative coding scheme founded on landmarks in the shape. The scheme encodes a qualitative representation of angles, relative side lengths and curvatures at landmarks. We then show how such a representation can be used as a basis for reasoning about shapes using extracted shape features. We conclude with a preliminary analysis of 12 sketches of the architect Louis Kahn and show how they may be categorised based on these shape features.

title Definition of a Domain-specific Language to Represent Korea Building Act Sentences as an Explicit Computable Form
source Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 73-82
summary This paper aims to define the syntax of KBimCode Lan- guage as a domain-specific computer language to represent Korea Building Act sentences. KBimCode Language represents building permit requirements in Korea Building Act as explicit computable rules. KBimCode aims to accomplish the neutral and standardized way of rule-making in an easy-to-use syntax. This paper introduces the approach of language design and definition. The main concerns handled in the paper are: 1) features of building permit-related regula- tions in Korea Building Act are reflected in the strategy for the lexical and syntactic design of KBimCode Language; 2) specification of KBimCode based on the context-free EBNF notation is introduced; and evaluation of the language definition is performed. KBimCode is an ongoing project. Together with newly developed rule checking ap- plications, KBimCode will establish automated design quality assess- ment system in Korea.

title Comparison of the Effectiveness of Two Computer-Assisted Instruction Methods for Learning Architectural Concepts in Design Studio
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary In design studio, during the preliminary stage of a project, learning architectural concepts through the study of precedents is a common activity. A few computer-based tools for precedent study have been developed, however, most have focused on delivering information without considering aspects of learning concepts. Although the tools apply digital media, such as hypermedia and multimedia, their instructional method is limited to direct instruction for presentation of information. The design and development of the tools neglect the need of the study of concept learning, learners, and learning methods.

source Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 123-129
summary Learning architectural concepts through the study of precedents is a common activity in design studio. Traditionally, an instructor presents a design concept by showing selected examples using slides, photographs, drawings, texts and verbal analyses. This method relies on a linear mode of conveying design knowledge and is time bound. It emphasizes information retention and recall of facts rather than an understanding of information.

However, if information on architectural precedents are represented digitally in a system designed to promote understanding of the material rather than just present facts, then some disadvantages of the traditional method may be overcome and additional advantages may be achieved. This paper describes a computer-assisted lesson system designed to represent architectural concepts related to spatial composition in design by using graphic images and text and reports on its development, implementation and testing. The system relies on many characteristics, such as accessibility, interactivity, flexibility, rapid feedback, etc., which are known to foster effective concept learning. The paper also evaluates the viability and effectiveness of this system from a technological and logistical viewpoint as well as from a concept learning viewpoint, and concludes with a discussion on other potential applications.

summary Design studio is the core of architectural education. An essential part of designing is using information and knowledge obtained from non-studio courses. However, as the complexity of buildings increases, the amount of this information increases and there is a danger that essential design information may be ruined and overlooked because of time and place constraints. As a means to bridge the gap between non-studio courses and design studios, some architectural educators suggest that design studios should bring knowledge to students in the process of designing so that they can apply this knowledge to their design. Most architectural studios, however, do not do enough to bring knowledge systematically into design projects when appropriate. Design projects generate need for additional knowledge about a number of topics, but too few studios systematically make knowledge available. Design studios should consider ways in which knowledge for design projects is integrally made available at the appropriate time. This paper describes a model for the delivery of design studio information which can be integral with any design projects. The model is demonstrated by a computer-assisted instruction (CAI) system designed and placed on the Web to introduce basic structural concepts and to teach an in-depth concept of spatial composition in a design studio and reports on its development, implementation, and testing. The system relies on many issues, such as access to relevant information, links between lessons for different subjects, representation of various design concepts, effective instructional methods for learning concepts, etc., which might be critical elements of designing an information communication system for design studio instruction. This paper tests the effectiveness of the system based on the results from responses of design studio students and observations of the researcher and the studio instructor, and concludes with the information that we hope will be useful in developing CAI materials for reflecting and acquiring information on a number of different subjects that have relevance to architectural design.

summary Within the contemporary condition, turbulence that confronts architecture is no longer unpredictable weather patterns or wild beasts, but the unintended forces of a constantly connected digital infrastructure that demands constant attention. If, as Mark Wigley puts it, “architecture is always constructed in and against a storm” it is time for architecture to reevaluate its ability to separate us from a new storm-one that situates technology, global connectivity, human, non-human and composite users, and algorithmic architecture itself as new weather systems. Toward this end, this paper explores architecture’s ability to mediate and produce algorithmic turbulence generated through image-based sensing of the built environment. Through a close reading of Le Corbusier’s Urbanisme, we argue that for much of the 20th and the early part of the 21st century, cities have been designed to produce diagrams of smooth and homogenous flows. However, distributed personal technologies produce virtual layers that unevenly map onto the city, resulting in turbulent forces that computational platforms aim to conceal behind a visual narrative of accuracy, cohesion, anticipation, and order. By focusing on SIFT algorithms and their ability to extract n-dimensional vectors from two-dimensional images, this research explores computational workflows that mobilize turbulence towards the production of indeterminate form. These forms demarcate a new kind of challenge for both architecture and the city, whereby a cultural appetite to deploy algorithms that produce a smooth and seamless image of the world comes hand in hand with the turbulent and disruptive autonomy of those very same algorithms. By revisiting Urbanisme, a new set of architectural objectives are established that contextualize SIFTS within an urban agenda.

summary Behavior, adaptation and responsiveness are characteristics of live organisms; architecture on the other hand is structurally, materially and functionally constructed. With the shift from ‘mechanical’ towards ‘organic’ paradigm (Mae-Wan Ho, 1997) attitude towards architectural adaptation, behavior and performance is shifting as well. This change is altering a system of reference and conceptual basis for architecture by suggesting the integration of dynamics – dynamics that don’t address kinetic movement only but include flows of energies, material and information. This paper presents an ongoing research into kinetic material system with the focus on non-mechanical actuation (shape memory alloy) and the structural and material behavior. It proposes an adaptive surface capable of altering its shape and forming small occupiable spaces that respond to external and internal influences and flows of information. The adaptive structure is developed as a physical and digital prototype. Its behavior is examined at a physical level and the findings are used to digitally simulate the behavior of the larger system. The design approach is driven by an interest in adaptive systems in nature and material variability (structural and functional) of naturally constructed materials. The broader goal of the research is to test the scale at which shape memory alloy can be employed as an actuator of dynamic architectural surfaces and to speculate on and explore the capacity of active and responsive systems to produce adaptable surfaces that can form occupiable spaces and with that, added functionalities in architectural and urban environments.

summary Today, thanks to current technological achievements, deepening and broadening of scientific information and knowledge, as well as expansion in our understanding of the world around us and underlying processes that govern metabolisms of natural world, we are able to see deep connections between the made and natural worlds. With such an expansive context comes an ability to effectively and productively integrate new knowledge, information, methods and techniques back into the design and production of architecture. Confluence of various technologies and their assimilation are altering the way we perform, organize and distribute our activities and materials. The conceptual model of architecture is changing.

summary Over the past decade, there has been an increasing interest in exploring the capacity of built spaces to respond dynamically and adapt to changes in the external and internal environments. Such explorations are technologically and socially motivated, in response to recent technological and cultural developments. Advances in embedded computation, material design, and kinetics on the technological side, and increasing concerns about sustainability, social and urban changes on the cultural side, provide a background for responsive/interactive architectural solutions that have started to emerge. This paper presents an ongoing design research project driven by an interest in adaptive systems in nature and a desire to explore the capacity of built spaces to respond dynamically. The paper underlines architecture’s inseparable link to technology and projects a vision of architecture that, through its capacity to change and adapt, becomes an integrated, responsive, adaptive and productive participant within larger ecologies.

summary As design research continues to gain momentum in South America, design researchers and practitioners in the region have begun to consider how to the field may address regionally-specific issues, including on-going political struggles. By bringing approaches such as Participatory Design and Adversarial Design that consider political aspects of design, local researchers have explored various forms that these two approaches could take that are tailored to the needs and values of different communities across the region. This paper focuses on identifying opportunities for developing design research projects in community-based and grassroots-oriented contexts. The paper presents the findings of our study about the understanding and experience of design researchers and experts who have been working closely with community groups and grassroots organisations in South America. Five themes emerged, highlighting opportunities and challenges related to positioning contemporary design research in the region, integration of adversarial perspectives into design processes, leveraging local obstacles through creativity, and the potential of building capacity within community groups and grassroots organisations for sustainability and autonomy.

source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 560-564
summary In this investigation we are concerned with rethinking and proposing the concept of space towards an enhanced interactive place where our spatial surroundings are no longer understood as fixed but as living organisms that adapt to our inter-actions inside of them. It is the aim of the research to show a space created by the interaction of the users with the building rather than the one generated by the personal interpretation of the designer. A place co-created by its inhabitant in real-time through a virtual prototype. Hereby, we are interested to investigate human-computer interactions inside of game engines as a morphogenetic process for potential architectural design and space conception. This research not only underlines theoretical concepts of architecture and folding as a spatio-structural diagrams that generate emergent processes in architecture design, but also proposes the creation and further development of a prototype based on these potentials that computer games and multimedia have brought to experiment and determine architectural environments. With the potentials of 3D Real-Time engines as design environments for the co-development of user driven spaces and folding as a design formation attitude we aim to determine space within the experience of a space prototype.

title Craft and Geometry in Architecture: An Experimental Design Studio Using the Computer
source Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 171-176
summary Craft is one of the main aspects of architecture that accounts for its strong corporeal presence. The Computer used as a geometry machine lacks such tectonics. The predominant means for bringing a sense of materiality to its geometric constructions is through rendering, and in this respect the computer is not significantly different from geometric drawing. One need only recall the beautifully rendered drawings of the Beaux-Arts for a comparison. With the rise of modern architecture such 'paper' architecture was voraciously denounced in the cause of relating architectural production more closely with crafted production. Even now the interest in craft has persisted despite postmodern criticism. Therefore, a means for bringing a greater sense of craft to computer-aided design seems desirable. The architectural studio discussed in this paper was initiated partly for this purpose by intentionally confronting the computer's proclivity to move its users away from craft toward geometry, while at the same time taking advantage of its capabilities as a geometry machine. Craft can best be understood by practicing it. Consider, for example, the use of a chisel in woodwork. As one applies force with it, one can feel the resistance of the material. Carving with the grain feels differently than carving against or across it. Carving a piece of maple feels differently than carving a piece of pine. If one presses too hard on the chisel or does not hold it at the precise angle, there is a great risk of creating an unwanted gouge. Gradually with practice the tool feels as if it is an extension of the hand that holds it. it becomes an extension of the body. One can feel the physical qualities of the wood through it. Like a limb of the body its presence can become transparent and one can learn about what one feels through it. It can imprint a memory in the mind that comes to the brain, not through the eyes alone, but through the tactile senses. On the other hand it is tiring to use a chisel for an extended period of time. One's body begins to ache and, as the body tires, the risks of making an unwanted mistake increase. Furthermore, because a tool becomes wedded to the body, it is almost impossible to use more than one tool at a time unless they are being used in conjunction with one another as one might use two limbs of the body together. On a computer one can never 'feel' an object, the image of which is on the screen, in the same manner that one can feel with a chisel the material upon which one is working. One becomes particularly aware of this when creating a 3D computer model of a hand tool. One wants to hold it, not just look at it. Thus the artifice of the object created by means of the computer becomes very apparent, because the 'tool' has not yet taken on the qualities of a tool, although it has taken on the appearance of one.

summary Form-active Systems offer an intuitive means of gaining direct and tangible knowledge for addressing architectural design problems with degrees of complexity typically beyond our capacity or desire to engage as designers. With these systems as a mechanism for research, we may establish a rich territory in which form, force, and matter are inherently imbricated in their conceptual domain. Furthermore, if we approach this conceptual terrain with an understanding that the elements of these systems exist along a continuum between the real and the virtual, we may incorporate methods and techniques in the form of analog machines and physics-based simulation from architecture’s peripheral fields of structural engineering, physics, and computation. This paper presents an applied research framework undertaken in a continued sequence of seminars whereby Form-active Systems are analyzed for their performative characteristics, synthesized for operative design strategies, iteratively prototyped across scales, and redeployed within the context of a multi-story installation.

title Critical points for change - A vital mechanism for enhancing the conceptual design process
source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 98-105
summary The Conceptual design is not a linear process; it consists of sub-processes, levels of refinement, which are individual but interact with each other. Each level of refinement corresponds to the types of media and tools used during conceptual design. Architects take advantage of a broad palette of tools and media for design, because each tool has its own strengths and weaknesses and provides an additional value—an added level of vision—to the architect. This closely relates to the notion of Critical Points for Change (CPC) a contribution this study makes towards a better understanding of the uniqueness of the conceptual design process. CPC are crucial moments when the architect suddenly becomes able to “see” something which drives him to go back and either alter his idea and refine it or reject it and pursue a new one. They are crucial parts of the design process because they are a vital mechanism for enhancing design. This characteristic of the nature of the conceptual design process is independent of the tools. Nevertheless, the right tools play an extremely important role. The distinctive capabilities of each tool allow the architect to deal successfully with CPC and overcome the points in the design process where he or she feels “stuck.”

title Reciprocal Transformations Between Music and Architecture As a Real-Time Supporting Mechanism in Urban Design
source Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 493-499
summary The more complex our cities become the more difficult it is for designers to use traditional tools for understanding and analyzing the inner essence of an eco-system such as the contemporary urban environment. Even many of the recently crafted digital tools fail to address the necessity for a more holistic design approach which captures the virtual and the physical, the immaterial and the material. Handling of massive chunks of information, classification and assessment of diverse data is nowadays more crucial than ever before. We see a significant potential in combining the fields of composition in music and architecture through the use of information technology. Merging the two fields has the intense potential to release new, innovative tools for urban designers. This paper describes an innovative tool developed at the Technical University of Crete, through which an urban designer can work on the music transcription of a specific urban environment applying music compositional rules and filters in order to identify discordant entities, highlight imbalanced parts and make design corrections. Our cities can be tuned.

title Analog vs. Digital: why bother?
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 117-128
summary Architects take advantage of a broad palette of tools and media for design, analog and digital, because each tool has its own strengths and weaknesses and provides an additional value—an added level of vision—to the architect. This closely relates to the notion of Critical Points for Change (CPC) a contribution this study makes towards a better understanding of the uniqueness of the conceptual design process. CPC are crucial moments when the architect suddenly becomes able to “see” something which drives him to go back and either alter his idea and refine it or reject it and pursue a new one. They are crucial parts of the design process because they are a vital mechanism for enhancing design. The right choice and smooth combination of design tools, analog and digital, is critical for the design outcome. Using multiple tools allows the designer to overcome the possible influences and limitations imposed by a single tool. The current and evolving landscape is illustrated by coexistence, complementing and evolution of tools. The answer to the pseudo-dilemma of analog or digital is both.

title Conversation, Cognition and Learning
source Amsterdam, Elsevier
summary The Conversation Theory developed by G. Pask originated from a cybernetics framework and attempts to explain learning in both living organisms and machines. The fundamental idea of the theory was that learning occurs through conversations about a subject matter which serve to make knowledge explicit. Conversations can be conducted at a number of different levels: natural language (general discussion), object languages (for discussing the subject matter), and metalanguages (for talking about learning/langu age). In order to facilitate learning, Pask argued that subject matter should be represented in the form of entailment structures which show what is to be learned. Entailment structures exist in a variety of different levels depending upon the extent of relatio nships displayed (e.g., super/subordinate concepts, analogies). The critical method of learning according to conversation theory is "teachback" in which one person teaches another what they have learned. Pask identified two different types of learning strategies: serialists who progress through an entailment structure in a sequential fashion and holists who look for higher order relations.

title Function representation in geometric modeling: concepts, implementation and applications
source The Visual Computer, 11 (8) 429-446
summary Geometric modeling using continuous real functions of several variables is discussed. Modeling concepts include sets of objects, operations and relations. An object is a closed point set of n-dimensional Euclidean space with a defining inequality f x x xn ( , ,..., ) 1 2 0 °Ÿ . Transformations of a defining function are described for the set-theoretic operations, blending, offsetting, bijective mapping, projection, Cartesian product and metamorphosis. Inclusion, point membership and intersection relations are described. In the implemented interactive modeling system, we use highlevel geometric language that provides extendibility of the modeling system by input symbolic descriptions of primitives, operations and predicates. This approach supports combinations of representational styles, including constructive geometry, sweeping, soft objects, voxel-based objects, deformable and other animated objects. Application examples of aesthetic design, collisions simulation, NC machining, range data processing, and 3D texture generation are given.

summary As the title ‘Function Follows Performance in Evolutionary Computational Processing’ suggests, this paper explores the potentials of employing multiple design and evaluation criteria within one processing model in order to account for a number of performative parameters desired within varied architectural projects. At the core lies the formulation of a methodology that is based upon the idea of human and computational selection in accordance with pre-defined performance criteria that can be adapted to different requirements by the mere change of parameter input in order to reach location specific design solutions.

summary This paper describes and reflects about a workshop activity in the field of Digital Manufacturing technologies to build responsive shelters that interact with their users and the environment. It addresses a teaching strategy intended to overcome tooling or the simple use of instruments and proposes instead to frame the production of objects using a new language, or a new operative strategy, directly linked to the production of the objects. It addresses a teaching strategy behind the workshop two main levels: first, by the development of technical skills by means of an operative action directly linked to the production of the object, and not apart from the action of making it (as in learning first and applying later). And second - and no less important -, it helped foster the maturation of critical thinking arising from the creation of a dynamic object of architecture - with moving parts and programmed to respond to its users.

summary The new digital fabrication technologies are changing the production methods in contemporary society. The sharing of information, within a new logic of production, has the potential to change the current economic system. The present work look after the open source architecture for digital fabrication, through the constructive experience of House Magazine, developed by LAMO3d, Laboratory of 3d Models and Digital Fabrication on FAU-UFRJ. The project, sold in newsstands with the correspondent assembly instructions, aims to popularize the fabrication technologies by its absorption and transfiguration in popular culture. The open source projects and technologies promote the widening of uses of knowledge and technological advances, unlinking them from the big business and generating a dispersion of production. It is up to us to recognize its potential and shape its endless application possibilities.

summary The paper presents an educational method used in teaching design of high-rise buildings in the city center. The author outlines the processes developed by students, the tools they used and the final results of design studio project and the supporting seminar, focused on exploring information processes in design. For the purpose of the design studio the students developed their own generative strategies that allowed incorporating optimization procedures into the design process. Within the framework of the seminar classes students developed individual optimization tools with the use of genetic algorithms in order to explore the search space and select the best possible architectural solutions for the specified criteria. The students used the above-mentioned tools mostly during the building's form-finding design stage or attempted to optimize just the building structure.

summary When designing buildings in dense city centers, a very important step is to study the nearest surroundings of the plot, in order to enable the best possible placement of the building. Many aspects must be taken into account including urban, legislative, environmental and aesthetic factors. These factors, in particular the legislative ones, depend on local conditions. This article describes a methodology for the analysis of insolation of surrounding buildings in the context of local building regulations. A procedure is described that significantly accelerates this phase of the design process and permits integrating it with an optimization process concerning the location of the building on the plot. Examples of application of that procedure are presented and their limitations and capabilities are discussed.

summary 3D sampling is a robust new strategy for exploring and creating designs. 3D textures are sampled and mixed almost like music to create new multifunctional surfaces and material microstructures (Figure 1). This paper presents several design cases performed using 3D sampling techniques, demonstrating how they can be used to explore and enhance product ideas, variations, and functions in subtle and responsive ways. In each case, design variations are generated and their mechanical behavior is evaluated against performance criteria using computational simulation or empirical testing. This work aims to promote creativity and discovery by introducing irregular geometric structures within trial-and-error feedback loops.

title Building inspection: can computer vision help?
source Automation in Construction 7 (1) (1997) pp. 13-20
summary Computer vision is forever expanding into new areas, especially in the field of inspection. The work presented here shows how computer vision has the potential to improve the exterior inspection of large buildings. A robot is being developed at City University, London that will perform a number of tests and the initial use of computer vision is to locate the robot thus enabling the position of building defects to be recorded more reliably than at present. A system has been developed that allows the inspector to tag just four points on the building, seen through a camera, to points on a CAD diagram of that building. With that information, a mapping can be found, so that for any new point in the image, and in particular that of the robot, its position on the building can be found. Work has progressed to automate the process such that now the computer uses a number of image processing techniques to extract key features of the building scene. These features are compared and matched to a CAD diagram, from which the mapping between the image and diagram is produced. This then allows the true position of the robot to be found. Results are given for a model building and robot demonstrating the accuracy of the algorithm, together with some results from residential flats, concluding that computer vision can indeed help building inspection.

summary It has been argued that traditional building simulation methods can be a slow process, which often fails to integrate into the decision making process of non-technical designers, such as architects, at the early design stages. Furthermore, studies have shown that predicted energy consumption of buildings during design is often lower than monitored energy consumption during operation.In view of this, this paper outlines research to create a user friendly design tool that predicts energy consumption in real-time as early design and briefing parameters are altered interactively. As a test case, the research focuses on school design in England. Artificial neural networks (ANNs) were trained to predict the energy consumption of school designs by linking actual heating and electrical energy consumption data from the existing building stock to a range of design and briefing parameters.

summary This paper explores ideas in relation to the design and delivery of a university level curriculum aimed at producing computer artists. Theessential principle is that the organisation of the film industry is a useful paradigm, and that the paradigm can be used as a tool in the designand delivery of this kind of curriculum. The education of graduates destined for the “new media” industries is complex. A particular problemis to achieve balance between development of technological skills on the one hand and artistic and creative development on the other. The challenge for educators is that many students are motivated by acquiring technical expertise and may not realise the importance of artistic and creative development. Comparisons with the world of film are used to address the problem of balance. The background to this approach is discussed and some preliminary results, in terms of student attitudinal change, are described.

summary It is a curious characteristic of mankind to both revere and revile the use of technology within art but history proves that when scientific logic marries with artistic reasoning, innovative and original ideas are born. Computer Art can justify a 30-year history but despite its relative maturity, digital art continues to suffer from the age-old perception that art made by machine is not a legitimate art form. This paper looks at the digital-imagery prevalent in the public domain today and compares its stage of development to the historical precedents of perspective, photography and film.

title Experiencing Architectural Interiors and Exteriors in Computer Games
source International Journal of Architectural Computing vol. 5 - no. 1, pp. 128-143
summary This paper looks at the design of "place" in a game environment. It sets out to present a way of analyzing and evaluating game environments using Brian Sutton Smith's seven rhetorics of play as a framework. The question this paper investigates, is what can be learnt from our intrinsic ability to navigate our environment in relation to play? Physical architecture offers the game designer metaphors for virtual worlds that have meaning based on experiences people associate with them. True innovation in game-world design requires an understanding of our built environment that extends beyond the surface aesthetic appeal of architecture, through concentration on the way we experience architecture and interact with our built environment.

summary The present paper presents a framework for an Automated Code Compliance (ACC) system within a BIM environment. We begin by introducing the concept of ACC and its applicability in contemporary practice in general and BIM in particular. We proceed by introducing the mathematical method of Multi-Dimensional Data Fitting (MDDF) to develop singular structural design equations from multi-dimensional datasets of structural design equations employed in international design codes. We follow this by demonstrating how the MDDF output has been implemented in BIM-based software, to achieve code compliance. Finally, we demonstrate the overarching framework and how this can be implemented on a wide scale to achieve full ACC.

summary This paper discusses the potential of the application of principles of fractal geometry in small scale design, using the design of parametric furniture as an example. It begins by summarizing the fundamental mathematical principles of fractals and the, relatively limited, application they have had so far in design. A theoretical stance is taken, viewing fractals as form-generators with significant potential. From this, the main principles of a computational design methodology are established, drawing on parallels from other design periods. As proof-of-concept, the paper presents the application of the methodology in a specific brief for the design of a piece of furniture, accompanied with images that document and illustrates the process. A parallel is established between the 21st century methodology of digital craftsmanship presented here, and the 19th century Arts & Crafts movement. Finally, the paper presents directions for further research which would allow the utilization of fractals in different design scales.

summary This paper discusses the potential of a BIM platform for offsite timber construction within the context of the UK construction industry. It examines the benefits, limitations, and challenges that BIM brings for offsite timber. Proof-of-concept projects are presented that deal with the architectural technology, structural engineering, and life cycle analysis aspects. These demonstrate the feasibility of the development of an open BIM platform which would establish a common standard for the industry. The paper concludes by suggesting an alternative business model for offsite timber construction, as enabled by Building Information Modelling.

source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary The purpose of this work was to delineate the sense of using instructional applications with digital media, not to replace but to support the activities of the courses of morphology for Industrial Design. On this occasion we concentrated only on explanatory material. We found out that there are two main features that justify the application of these new media. They are constituent aspects of them: density and flexibility. Density is obtained through the multiple representations that digital media enable. Flexibility allows us to bring these representations together in alternative narrations, according to the different requirements of our teaching activities. An educational application, in order to be educational, should be dynamic and changing, defying the idea of an optimized and unique way of reaching comprehension. So, an intentional use of digital media becomes a powerful and accessible tool to make this happen.

title THE DIGITAL IMAGE IN THE MEDIATION BETWEEN ARCHITECT AND USER
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005
summary Digital mediation is considered to facilitate architect-user understanding, in order to enlarging the communicative competition, causing an involved attitude in the receptor. This paper proposes the study and analysis of the new communicative situation with the purpose of evaluate the impact of digital mediation in the understanding between producer and user. The investigation is focused as a comprehensive qualitative study. The process begins when the receptor contacts to media and then, it is able to observe attitudes and communicative competitions that play in the relationship. Variables involved in defi nition of digital mediation are: content, consumption ways, structures, digital image and alternative means. Observable attitudes of the receiver are organized in three categories: cognition, perceptive and emotive. Functional methodological tools are hoped to be found in order to evaluate the reach and infl uence of DM in the producer-user communication.

summary This paper describes a generative evolutionary design system that aims to fulfil two key requirements: customisability and scalability. Customisability is required in order to allow the design team to incorporate personalised and idiosyncratic rules and representations. Scalability is required in order to allow large complex designs to be generated and evolved without performance being adversely affected. In order to fulfil these requirements, a computational architecture has been developed that differs significantly from existing evolutionary systems. In order to verify the feasibility of the this architecture, the generative process capable of creating three-dimensional building models has been implemented and demonstrated.

summary For complex parametric modelling tasks, systems that use textual programming languages (TPLs) currently have clear ad- vantages over visual programming languages (VPLs) systems. Their support for a rich variety of programming mechanisms means that the complexity of the program can remain commensurate with the com- plexity of the modelling task. A prototype parametric modelling sys- tem called Mo?bius is presented that aims to overcome the limitations of existing VPL systems. The proposed system integrates associative and imperative programming styles and supports iterative looping and higher order functions. In order to demonstrate the versatility of the Mo?bius, a modelling task is presented that requires the model to be modified.

summary When visual programming is applied to design, it results in a parametric modelling approach that we refer to as Visual Dataflow Modelling (VDM). This paper reviews existing VDM environments and identifies key issues that result in dataflow graphs with high complexity. In order to explore how these issues could be overcome, a new VDM environment is being developed, called Vidamo. For any given parametric modelling task, Vidamo aims to support a style of VDM where the complexity of the dataflow graph remains commensurate with the complexity of the task. An initial experiment is conducted in which the existing environments and the proposed Vidamo environment are used to complete the same parametric modelling task. The results indicate that the dataflow graphs created using Vidamo are much smaller and less complex.

title Toward Temporal and Punctual Urban Redevelopment in Dynamic, Informal Contexts - An Adaptive Masterplan Driven by Architectural Interventions Using Multiagent Modeling

summary This paper presents design research speculating on new planning approaches for informal urban sites that enables coordinated planning to operate within the realm of spontaneous, bottom-up redevelopment. In opposition to the /tabula rasa/ Modernist development, this project reacts to the dynamic metabolism of the village and engages with the rapid turnover of the built environment of the village as a mechanism through which to implement incremental redevelopment. A radical reorientation of the object of masterplanning, this replaces the singular image or document as the guiding authority with a collection of opportunistic adaptations, temporal sequences, and localized procedures. Enabling this approach is a computational approach that analyzes the morphology of the public space network to identify opportunities to address issues in the composition of the village. A multiagent system driven by weighted random walks through the circulation network conducts local analyses of the urban fabric while changes are made and proposes potential modifications to discrete areas. The model simulates the potential for such a planning tool to be used over a long time span and updated with empirically gathered data, having the benefit of flexibility and resilience in the face of the changing and unregulated conditions in the context of informal urbanism.

summary Cellular automata offer a compelling model for complex generative design. However, the abstraction of classical cellular automata models hinders their application in the design process, particularly at small scales where regular grid matrices do not provide an adequate approximation. This paper presents some tests in appling these generative properties to a real site using irrregular tesselation adapted to the terrain and an spreadsheet interface that translate design concerns into set of neighborhood and state behaviors with the goal of generating massing diagrams for an urban masterplan. The development of the model over time is also presented as a visual reference that aids in comparing different parameter sets and informing the design process.

title Rendezvous: An Architecture for Synchronous Multi-User Applications
source Proceedings, Conference on Computer-Supported Cooperative Work. New York: ACM, pp. 317-328
summary Rendezvous is an architecture for creating synchronous multi-user applications. It consists of two parts: a run-time architecture for managing the multi-user session and a start-up architecture for managing the network connectivity. The run-time architecture is based on a User Interface Management System called MEL, which is a language extension to Common Lisp providing support for graphics operations, object-oriented programming, and constraints. Constraints are used to manage three dimensions of sharing: sharing of underlying information, sharing of views, and sharing of access. The start-up architecture decouples invoking and joining an application so that not all users need be known when the application is started. At present, the run-time architecture is completed and running test applications. As a first test of the complete Rendezvous architecture, we will implement a multi-user card game by the end of the summer.

summary I approach a bridge, an escape from the hard concrete floor of Bangkok, and happen to eavesdrop on the silent call of an elephant herd marching into my perception. It now appears in a forest behind the window of a large wall. The forest spreads deeper and deeper beyond the limit of a brick and concrete surface. The wall transforms into the mysterious rain forest of Thailand - robust, complex and healthy. A beam of friendly sunlight penetrates the air of an open well and greets the floor of the forest, it enters to enlighten all of its inhabitants' hearts. ... As I am immersed in the forest, I hear the chimes of its quietness and come face to face with the herd of elephants, marching into the middle of the place. ... All of the elephants in fact are made of wood, however their skin transcends the form of a hard wooden object for it is now transformed into the breathing skin of real elephants - the mothers of the forest. Wherever is felt the breath of the mother of the forest the place flourishes as a healthy world for all life. Here, I can hear the sonority of the quietness upon a visit to the office of A49, the office of Khun Nithi Sathapitanonda.

summary This paper describes current progress of an interview study of architects which considers how these individuals design, focusing on breakthroughs and unexpected discoveries made throughout conceptual design. The study considers creative outcomes that occur while these individuals are not intentionally designing, as well as when they are, with the intention of identifying and evaluating evidence of latent creative activity. While not described in this paper, issues of insightfulness, based on a Gestalt perspective, are also considered in the study. The completed interviews described in the paper suggest that, in order to achieve breakthroughs, designers adopt distinctive methods of disengaging from currently unproductive designing. These may be categorized by degree and type of disengagement, or subsequent re-engagement. In general, disengaging, instead of persisting in designing, when apparently stuck, appears to be the rule rather than the exception. Statements by the interviewees suggest that discoveries during, or just after, times when they are not actively designing, referred to as cold discoveries, are more important than is currently recognized, which is scarcely at all. Statements describing interviewee experiences of discovery and providing indications of the genesis of discoveries are included in the paper. The paper discusses implications of the wide range of perceptions and experiences of each individual. One interesting finding is that individuals appear to experience and appreciate cold discoveries regardless of differences in key aspects of the way they design, described in the paper. This suggests that the genesis of cold discoveries may be as complex as that of discoveries in general.

summary To make our cities sustainable is one of today's major challenges. The complexity of this task requires suitable planning tools. The aim of this paper is to present a hierarchical modelling approach to assess the effects of transport and land use projects and instruments. First a brief definition of the overall objective sustainability is given. This is followed by the description of the suggested hierarchical approach. A strategic, dynamic land use and transport interaction model builds the basis and is linked to models on a different spatial and functional level. A case study covering the Spanish region of Madrid ('Comunidad de Madrid') was selected to demonstrate the applicability. In particular the effects of the public transport infrastructure projects, the extension of the metro line number 9 and bus lanes on all radial highways, should be assessed. It is demonstrated that the suggested approach is applicable and suitable. The overall effect of the metro line extension and the bus lanes is positive. Nevertheless their contribution to a sustainable urban region is limited. Comprehensive strategies are needed to achieve the objective of sustainability. It could be shown that the projects can even have some negative local effects in the long term.

summary Volume modeling, finite element computation and spatial information systems have a common basis in topology, especially in the theory of complexes which are higher dimensional generalization of graphs. A complex is a topological space having a certain algebraic structure called “chain complex” and due to its similarity to real world buildings a special kind of complexes are even called “buildings” in mathematics. So it would be consequent to base a building information system upon this theory or at least try to do so. Some manipulations and queries of such spaces can then be expressed by mappings which are similar to complex-morphisms and generalize the well known Euler operators. Other practical useful operations like assigning a detail to a spatial element (“refinement”), hiding details at lower scale views (“coarsening”) or spatial versioning, however, need a somewhat different kind of mappings. This paper shows a simple relational database representation of a finite complex as a basis for a database backed building information system. The implementation of operations on such a relational complex in Java will also be shown.

summary This paper describes the rationale for a navigational system that supports context-based exploration of the urban environment. While many navigational tools support wayfinding, they are based on targeted search, requiring the user to have a predetermined destination. Existing applications do not offer navigational mechanisms that base their recommendations on the user’s unique context information. Customised recommendations present the user with relevant routes they may not have discovered on their own. In this paper, a parallel is drawn between wayfinding in the physical world and the virtual, with web surfing acting as a metaphor for a particular style of interaction with the physical environment. Similarly, the framework for this system presents suggested routes to the user according to their unique contextual setting, which is anticipated to allow a more explorative engagement with their physical environment.

source Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 687-696
summary Web-enabled collective intelligence in design invites anyone to contribute to a design process through crowd-sourcing. We use a protocol analysis method to analyse the forum data on a collective intelligence web site, studying communication among individuals who are motivated to participate in the design process. A protocol analysis allows us to compare collective intelligence in design to similar studies of individual and team design. Our analysis shows that a design process that includes collective intelligence shares processes of ideation and evaluation with individual and team design, and also includes a significant amount of social networking. Including collective intelligence in design can extend the typical design team to include potential users and amateur perspectives that direct the design to be more sensitive to users’ needs and social issues, and can serve a marketing purpose.

source Proceedings of the 5th International Conference on Advances in Mobile Computing and Multimedia, Jakata, Indonesia, December 3-5, ISBN978-3-85403-230-4, pp. 31-40
summary Web surfing, the act of following links of interest with no pre-defined search goal, is a paradigm that can be translated to the physical realm of urban exploration. With mobile computing technology and its supporting infrastructure becoming ever more ubiquitous, a user's digital device can be transformed into a portal that connects their physical environment with the virtual, providing instant access to a plethora of information that can influence and guide their interactions with the city. This paper describes the technical aspects of a context-aware system for urban exploration based on the paradigm of web surfing. An implementation is presented that demonstrates a browsing style of interaction with an urban environment through context-based navigational prompts.

title Quantifying Immersion in Virtual Reality
source Proceedings of SIGGRAPH‘97, 13-18
summary Virtual Reality (VR) has generated much excitement but little formal proof that it is useful. Because VR interfaces are difficult and expensive to build, the computer graphics community needs to be able to predict which applications will benefit from VR. In this paper, we show that users with a VR interface complete a search task faster than users with a stationary monitor and a hand-based input device. We placed users in the center of the virtual room shown in Figure 1 and told them to look for camouflaged targets. VR users did not do significantly better than desktop users. However, when asked to search the room and conclude if a target existed, VR users were substantially better at determining when they had searched the entire room. Desktop users took 41% more time, re-examining areas they had already searched. We also found a positive transfer of training from VR to stationary displays and a negative transfer of training from stationary displays to VR.

summary Research initiatives throughout history have shown how a designer typically makes associations and references to a vast amount of knowledge based on experiences to make decisions. With the increasing usage of information systems in our everyday lives, one might imagine an information system that provides designers access to the 'architectural memories' of other architectural designers during the design process, in addition to their own physical architectural memory. In this paper, we discuss how the increased adoption of semantic web technologies might advance this idea. We briefly discuss how such a semantic web of building information can be set up, and how this can be linked to a wealth of information freely available in the Linked Open Data (LOD) cloud.

summary Although many shape grammars and corresponding implementations have been proposed, shape grammars are not widely adopted by architectural designers. In this paper, we therefore look for the barriers of implementing and using shape grammars for architectural design. We do this by outlining several implementation strategies of shape grammars, we briefly point to our own graph-based design grammar system, and we analyse the resulting overview using theories on how designers think and act upon incoming information. Based on this analysis, we develop and suggest how design grammars might best be implemented and used for architectural design relying on the information technologies available at this particular moment of time.

summary This paper illustrates our findings concerning space based design methodologies and interoperability issues for today’s Building Information Modeling (BIM) environments. A method is elaborated which enables building designers to perform an automated energy use analysis, based on an Industry Foundation Classes (IFC) model derived from a commercial BIM environment, in this case Autodesk Revit 9.1. A prototype application was built, which evaluates the building model as well as vendor-neutral exchange mechanisms, in accordance with the Flemish Energy Performance Regulation (EPR) standard. Several issues regarding the need for space-based building models are identified and algorithms are developed to overcome possible shortcomings.

title Preservation of Architectural Heritage Through 3D Digitization
source International Journal of Architectural Computing vol. 5 - no. 2, pp. 222-237
summary Continuity and relation to the past are inherent in human nature. The remains of the past constitute culture and cultural heritage. Preservation and dissemination of cultural heritage appear to be, nowadays, a universal priority. Historic/architectural monuments are among the most significant categories of cultural heritage and their 3D digitization appears to be a chief way towards that direction. 3D digitization of architectural heritage is a very specific problem in the digitization domain. Since size, budget and applicability are some of the most important factors in choosing an appropriate digitization method, and since there is not an all-in-one solution in digitization, this problem cannot be always addressed by using one technique. In this paper we review methods that are available for 3D digitization of architectural heritage and we present two case studies of real-world digitization projects involving monuments and urban areas.

summary This paper proposes the use of a new set of software tools, called Firefly, paired with a low-cost five-axis robotic motion controller. This serves as a new means for customized tool path creation, realtime evaluation of parametric designs using forward kinematic robotic simulations, and direct output of the programming language (RAPID code) used to control ABB industrial robots. Firefly bridges the gap between Grasshopper, a visual programming editor that runs within the Rhinoceros 3D CAD application, and physical programmable microcontrollers like the Arduino; enabling realtime data flow between the digital and physical worlds. The custom-made robotic motion controller is a portable digitizing arm designed to have the same joint and axis configuration as the ABB-IRB 140 industrial robot, enabling direct conversion of the digitized information into robotic movements. Using this tangible controller and the underlying parametric interface, this paper presents an improved workflow which directly addresses the shortfalls of multifunctional robots and enables wider adoption of the tools by architects and designers.

summary In the early 60s, the British group Archigram created and promoted a new understanding of architecture and land, incorporating with its innovative vision, the scientific paradigms and technological advances of the second half of the twentieth century. The result of these explorations resulted in the emergence of theoretical and concrete proposals with technology as the main protagonist in the physical resulting, through a poiesis which postulated mobile transience as an active paradigm. Fifty years later, today, this situation has similarities and differences with the time it was given, and deserves a special consideration in this topic.

summary Colonia del Sacramento (capital of Colonia department, in Uruguay) has been registered in the list of the Convention Heritage concerning the protection of worldwide cultural and natural heritage. The registration on this list (December 6th 1995) confirms the exceptional and universal value of a cultural or natural places which deserves protection for the whole humanity. The ancient Colonia del Sacramento founded in 1680 by Portugal, was a commercial and military site leading role of the historical controversy between Spain and Portugal. Main place of wars and treaties during a century, it keeps an urban design, unique in the area and valuable architectonical testimonies of different periods of this rich past, with a simple, popular profile. This work has been effected within the Clemente Estable Found 1996, which is promoted by National Council of Scientific and Technical Research (CONICYT). Through virtual reality techniques, a three-dimensional model of Colonia del Sacramento city was built as it was in its period of prosperity (around 1762). For the achievement of this digital maquette, a great deal of written and graphic information was compiled and processed. This information was organized in an inventory way (with numerous readings and searches). The inventory and the digital maquette were joined in a multimedia application (CD-ROM) which allows potential users to move through virtual city and friendly and interactively consult images, graphics and texts.

summary The ubiquity of the digital computer is revolutionizing our understanding of architecture, a paradigm shift comparable to the Renaissance real perspective, the Industrial Revolution of the XIX century, and the technological and scientific discoveries of the early part of the XX century. The creation of virtual worlds, with their own laws and logics, is one of the most important contributions of the digital era. The paradigms of modern architecture are being replaced by other models. The advent of the digital age erased the boundary between “original” and “copy”. Working with design fundamentals and not merely with its graphical manifestations will produce a revolution in architectural design, similar to the genetic revolution of decoding the human genome. Centralized, “star-topology” design locations, are being replaced by distributed, “circle-topology” design teams. The direct influence of digital technologies on the analysis, creation, and realization of architecture also must produce similar revolutions in the teaching of architecture.

summary Through the formation of bio-chemical information networks natural materials possess efficient processes of self-organization, adaptability, regeneration and decomposition. This performative excellence has lead science to draw behavioral models from nature implementing biomimmicry (Benyus 1998) in the pursuit of material systems optimization. Design disciplines influenced by this course are integrating living organisms as models of efficiency through bionic systems ever more into their discourse. Architecture, influenced by this tendency, is becoming progressively more aware of the vast benefits that biomimetics can yield particularly in the development of ecologically sensitive systems. Yet, the emerging incorporation of bionics into architecture is differing largely to that within the sciences by centering almost exclusively in form (geometrical pattern) generation. This paper analyzes a rising material design research methodology implementing biomimetics: matter-form parametrics based on bio-physical properties’ data. Specific study of the incorporation of broad-scalar scientific imaging into the formulation of explorative parametric grammar for the development of material systems is analyzed through a bio-synthetic polymer based wall system (SugarWall, Gensler+Gutierrez 2006b). The incorporation of broad scalar imaging and material interdependencies is propelling the emergence of new programming tactics that will affect bio-material systems architectural research.

summary v Knowledge is commonly socially constructed, through collaborative efforts... v Intelligence may also be distributed for use in designed artifacts as diverse as physical tools, representations such as diagrams, and computer-user interfaces to complex tasks. v Leont'ev 1978 for activity theory that argues forcibly for the centrality of people-in-action, activity systems, as units of analysis for deepening our understanding of thinking. v Intelligence is distributed: the resources that shape and enable activity are distributed across people, environments, and situations. v Intelligence is accomplished rather than possessed. v Affordance refers to the perceived and actual properties of a thing, primarily those functional properties that determine how the thing could possibly be used. v Norman 1988 on design and psychology - the psychology of everyday things" v We deploy effort-saving strategies in recognition of their cognitive economy and diminished opportunity for error. v The affordances of artifacts may be more or less difficult to convey to novice users of these artifacts in the activities to which they contribute distributed intelligence. v Starts with Norman's seven stages of action Ø Forming a goal; an intention § Task desire - clear goal and intention - an action and a means § Mapping desire - unable to map goal back to action § Circumstantial desire - no specific goal or intention - opportunistic approach to potential new goal § Habitual desire - familiar course of action - rapidly cycle all seven stages of action v Differentiates inscriptional systems from representational or symbol systems because inscriptional systems are completely external, while representational or symbol systems have been used in cognitive science as mental constructs. v The situated properties of everyday cognition are highly inventive in exploiting features of the physical and social situation as resources for performing a task, thereby avoiding the need for mental symbol manipulations unless they are required by that task. v Explicit recognition of the intelligence represented and representable in design, specifically in designed artifacts that play important roles in human activities. v Once intelligence is designed into the affordances properties of artifacts, it both guides and constrains the likely contributions of that artifact to distributed intelligence in activity. v Culturally valued designs for distributed intelligence will change over time, especially as new technology becomes associated with a task domain. v If we treat distributed intelligence in action as the scientific unit of analysis for research and theory on learning and reasoning... Ø What is distributed? Ø What constraints govern the dynamics of such distributions in different time scales? Ø Through what reconfigurations of distributed intelligence might the performance of an activity system improve over time? v Intelligence is manifest in activity and distributed in nature. v Intelligent activities ...in the real world... are often collaborative, depend on resources beyond an individual's long-term memory, and require the use of information-handling tools... v Wartofsky 1979 - the artifact is to cultural evolution what the gene is to biological evolution - the vehicle of information across generations. v Systems of activity - involving persons, environment, tools - become the locus of developmental investigation. v Disagrees with Salomon et al.'s entity-oriented approach - a language of containers holding things. v Human cognition aspires to efficiency in distributing intelligence - across individuals, environment, external symbolic representations, tools, and artifacts - as a means of coping with the complexity of activities we often cal "mental."

source SIGGRAPH '85 Conference Proceedings. July, 1985. vol. 19 ; no. 3: pp. 279-286 : ill. includes bibliography
summary Texturing is an effective method of simulating surface detail at relatively low cost. Traditionally, texture functions have been defined on the two-dimensional surface coordinate systems of individual surface patches. This paper introduces the notion of 'solid texturing.' Solid texturing uses texture functions defined throughout a region of three-dimensional space. Many nonhomogeneous materials, including wood and stone, may be more realistically rendered using solid texture functions. In addition, solid texturing can easily be applied to complex surfaces which are difficult to texture using two- dimensional texture functions. The paper gives examples of solid texture functions based on Fourier synthesis, stochastic texture models, projections of two-dimensional textures, and combinations of other solid textures

source IEEE Expert 7(5): 14-20
summary Archie, a small computer-based library of architectural design cases, is described. Archie helps architects in the high-level task of conceptual design as opposed to low-level tasks such as drawing and drafting, numerical calculations, and constraint propagation. Archie goes beyond supporting architects in design proposal and critiquing. It acts as a shared external memory that supports two kinds of design collaboration. First, by including enough knowledge about the goals, plans, outcomes, and lessons of past cases, it lets the designer access the work of previous architects. Second, by providing access to the perspectives of domain experts via the domain models, Archie helps architects anticipate and accommodate experts' views on evolving designs. The lessons learned about building large case-based systems to support real-world decision making in developing Archie are discussed.

summary The Creative Synthesis task devised by Finke and Slayton(1988) has been widely used as an experimental measure of mentalsynthesis, but previous studies have often failed to demonstrate anysignificant benefits of external support on participants’ performance.This paper discusses a study that examined novice and expert drawers’performance of synthesis using a modified stimuli set that was designedto increase the load on visuo-spatial working memory. The resultsshowed a significant increase in Transformational Complexity(Anderson & Hesltrup, 1993) of patterns produced by the expert groupwhile using sketching. It is argued that experts are more effective atusing sketching interactively to increase complexity, while novices relymore on using it as a simple memory aid.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.755-763
summary The scope of this paper is the identification of elements in architectural space that can trigger human behavior in both real and virtual environments. These elements can be either material, such as shapes and volumes or immaterial, such as light and shadow. Our research depends on a series of experiments taking place in an existing architectural environment (a high-school) and its virtual counterpart, focusing mainly on the spatial perception and cognition by the subjects through real-time navigational means. The aspect that survey knowledge (spatio-exploratory or exocentric perception) is “primary” in virtual environments seems to be confirmed. It is indicative that in the virtual environment the movement of subjects (primarily visitors) is related and defined strongly by specific architectural elements, such as a stoa and the staircases, while being strongly exploratory.

source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 724-729
summary This paper investigates the difference of spatial perception and cognition between virtual and real architectural environments. Specifically, three different aspects have been studied, concerning the live perception and cognition of a complex actual building, the perception and cognition of a high quality rendered virtual space, as well as the perception and cognition of a non-photorealistic virtual environment. To study the differences between these three types a series of experiments were prepared, in which students of architecture participated and statistical results were drawn. Earlier studies have investigated the desirability of key simulation attributes for architectural design visualization, but extensive research on what contributes to a better spatial comprehension is still missing. This experiment is part of a series of experiments mainly focused on the perception and cognition in virtual spaces. The results of these experiments were correlated with each other, each one leading to new ideas of experimentation. Preliminary results confirm earlier findings from previous similar experiments. It was found that there was a statistically significant tendency of the students towards larger scatter in more luminous virtual space as well as a tendency to visit the lit part of virtual space. Visitors of the photorealistic spaces also seem to have better knowledge of the depth of space in comparison to those navigating in the non photorealistic space.

summary The SHADOWPACK package of computer programs has been developed to facilitate shading evaluations, for the direct component of solar radiation, with general 3D models. An interactive solid modelling program allows the user to construct and view the 3D model before saving it for further analysis and display. Other programs permit the graphical display of the shading situation throughout the year, the quantitative assessment of energy received on different faces of the model, and the display of the distribution of energy received on particular faces by means of contour plots. The use of the computer graphics approach has proved particularly convenient because of the similarity between the techniques used for graphical and numerical algorithms

source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The growing requirement for spatial decision support systems in Urban and Regional Management is pointed out. This has come about due to the increasing complexity of modern human activities, the increase in awareness of the negative consequences of mankind's technological development on the environment, and also due to the need to respect new regulations and legislation regarding environmental impacts. Such spatial decision support systems need to manipulate and analyze a wide variety of spatially referenced information, frequently in large quantities. Geographical Information Systems are now the chosen means for supporting such information, but in order to arrive at decisions further analysis modules and decision aids frequently need to be linked to them, or integrated with them. Linking multicriteria decision aid with spatial analysis is one way in which spatially referenced information can be used to arrive at decisions in situations where there are many and conflicting criteria. Examples of applications of these ideas to real management problems, including waste management, river management and site management are used to show how spatial information can now be manipulated to aid decisions, and to arrive at some of the design requirements for more flexible and applicable decision support systems. The merits and disadvantages of several different approaches to design and implementation of decision support systems, especially from the users point of view, are discussed.

This project strays from traditional methods of structuring a city and investigates a novel self-engineered anticipatory model, which focuses on the use of generative and genetic algorithms to develop a new associative system to develop coastal cities in arid climates. The system functions as a negative feedback loop, analysing existing conditions, and by a series of mathematical functions, projecting the new growth patterns for major components of a city, such as building envelopes, road networks, canal networks and public space distribution as a result of the cities internally generated resources.

summary Technological innovation has been an important driving force in architecture, enabling and inspiring architects and engineers by giving them new tools for solving existing problems. In the last two decades, the exploration of digital design and fabrication technologies has stimulated the development of a variety of interests and strategies to materialize increasingly complex and customized solutions in architecture, with traditional building materials. Reinforced concrete is the most widely used material in the building industry today and throughout its history has been the subject of vast research into its performance as a construction material and its tectonic potential in architecture. As such, the introduction of digital fabrication processes in concrete construction represents the biggest prospect for renovation of our built environment and at the same time, presents particular difficulties and opportunities, which are now being addressed. In an effort to investigate the alternative design and material possibilities in concrete emerging from the use of digital fabrication technologies in architecture, this paper proposes a focused view of digital fabrication applied to concrete construction with two areas of research. By framing the research in the context of reference works in concrete architecture of the 20th century, this paper describes and illustrates taxonomy of existing and possible types of integration of digital fabrication technologies in concrete architecture in the realms of Practice and Research.This characterization allows the authors to frame the relation between material, technology and architecture in different environments regarding the same material, extracting a clear image of existing processes, their potential and shortcomings, as well as expectations for future developments.

summary In the last two decades, CAD/CAM technologies have opened new conceptual and material opportunities in architecture. By combining computational design and digital fabrication technologies, architects have embraced a higher level of geometric complexity and variability in their solutions. Such non-standard possibilities were expanded with the recent introduction of robotic technologies in the discipline, which have allowed moving beyond the fabrication of building components to reach the construction of building parts. As a result of this digital condition, traditional materials have known innovative applications in architecture. In this context, this paper presents cork, which is a natural and recyclable material. By describing its unique set of properties and features, it argues about its relevance for the building construction in the present times. With this underlying motivation, this paper defines the current state of the research in architecture on the use of robotic fabrication with cork. It does so by describing and illustrating a set of different experiments conducted by the authors in their academic institutions. The results unveil a set of innovative applications of cork in building construction, and, at the same time, contribute to show how robotic technologies can be used to rethink and update traditional and old materials in architecture.

summary Software is shared through files and libraries, but workflows are not. To be able to share workflows for rapid automation, we developed an extensible environment for running CAD, CAM, and machine control. We present Mods, a browser-based environment for data handling, toolpath planning, and machine execution. Users compose modules (either existing modules or new modules they contribute) into workflows for machine automation sequences in a dataflow environment. The modules themselves run client side, implementing the functions used by the modules (such as toolpath planning algorithms or image analysis) in JavaScript, which runs in the browser. The physical machines are connected to a JavaScript server, which listens to commands from the client over a WebSocket connection. Together, these software modules make up an extensible and simple-to-use alternative to traditional CAD/CAM machine control environments.

title Exploratory investigation of solid freeform construction
source Automation in Construction 5 (5) (1997) pp. 427-437
summary A radical departure from generally accepted concepts in construction robotics is proposed in this paper. A new process derived from the emerging field of additive manufacturing processes is investigated for its potential effectiveness in construction automation. In essence, complex assemblies of large construction components are substituted with a large number of elemental component assemblies. The massive complexity of information processing required in construction is replaced with a large number of simple elemental operations which lend themselves easily to computer control. This exploratory work is illustrated with sample masonry structures that cannot be obtained by casting. They are manufactured by an incremental deposition of sand and Portland cement akin to Navajo sand painting. A thin layer of sand is deposited, followed by the deposition of a patterned layer of cement. Steam is then applied to the layer to obtain rapid curing. A characterization of the resulting material properties shows rather novel anisotropic properties for mortar. Finally, the potential of this approach for solid freeform fabrication of large structures is assessed.

summary It is undeniable that the computer has affected every aspect of our lives. Many people work with computers on a daily basis, from writing e-mail or simply browsing the internet to hours of serious modeling and drafting for those in the architecture field. As we spend more time working with computers, research into improving computer teaching and working environments becomes more important. For those working in an architecture office, it almost certain that a major part of the day will be spent in front of a computer drafting. This research provides a preliminary set of guidelines that can be applied in the design of computer working/teaching environments. The on-going research is focussed in creating facilities geared toward user comfort and productivity and improving teaching environments. It covers issues regarding the position and orientation of the room, lighting aspect (including natural and artificial light), acoustics, user visual comfort, psychrometric conditions, furnishings, and the adaptability of the space for future changes. The project includes analysis of existing examples of computer-lecture rooms, noting the problems and suggesting improvements.

summary Hutt (1966) demonstrated that familiarity, clarity, simplicity, and congruity are four stimulus characteristics eliciting play. When the participant reaches this status of an activity, in which is at this point that the playfulness element enters into play, and play is an important ingredient of the creative process. Correspondently, the characteristics in digital design studios which are rapid and broad exploration, systematic design process, the use of suitable digital media, and problem solving system reveal the analogical qualities with play. Since creativity is crucial in design processes, it is worthwhile to study relationships between play and digital design studio to discover possible means to benefit and facilitate digital design learning.

title MODELLING DETAILED INFORMATION FLOWS IN BUILDING DESIGN WITH THE PARAMETER-BASED DESIGN STRUCTURE MATRIX
source Design Studies, 27(1), pp. 99-122
summary The Architecture/Engineering/Construction (AEC) industry is one of the multidisciplinary domains in which collaboration among related parties is of utmost importance. Despite the intense flow of information between design professionals, there is a lack of research to better understand and manipulate these flows. Most of the current process modelling tools in the AEC industry do not enable analyses of iterative information cycles. Moreover, these tools represent the process at high levels, thus, they are inadequate for multi-parameter problems like building design. With a view to alleviate these problems, this paper introduces the use of parameter-based design structure matrix as a process modelling and system analysis tool for building design. The method reveals insights into the process structure, optimum sequence of parameter decisions, iterative cycles and concurrency in the process. The application of the method is demonstrated through a case study on suspended ceiling design in a real-life project.

source Design Studies, 27(1), pp. 99-122In B. Tuncer (Ed.), E-Activities in Building Design and Construction. (pp. 63-72). Paris: Europia
summary This paper reviews existing process models in the Architecture-Engineering-Construction (AEC) industry and identifies two common deficiencies in them: 1. Current process models used in the industry still have a top-down approach including very little information about interrelationships at lower levels. Although these models provide a good overview of the design process, they are often too abstract to define, in detail, for complex multi-parameter problems. 2. Iteration is an important problem in collaborative design. However, most of the existing process models fail in identifying and minimizing it. With a view to alleviate these problems, this paper introduces the parameter-based Design Structure Matrix (DSM) as a tool for process integration and improvement in building design. The uses of the tool are shown via simple examples and suggestions are made for further research.

source In C. J. Anumba (Ed.), Innovative Developments in Architecture, Engineering, and Construction. (pp. 25-31). Rotterdam: MillPress
summary Architecture/Engineering/Construction (AEC) industry is one of the multidisciplinary domains in which collaboration among related parties is utmost important. While the knowledge needed for building processes are distributed among the different participants from diverse disciplinary backgrounds, the product of their activities, i.e. the building itself, must be highly integrated. Despite the intense flow of information between design professionals, there is a lack of research to better understand and manipulate these flows. Furthermore, most of the current process modeling tools in the AEC industry do not enable analyses of iteration in the process and they represent the process at high levels with very little information at lower levels. In order to resolve the issues mentioned above, this paper introduces the use of parameter-based dependency structure matrix as a process modeling and system analysis tool for building design. The method reveals insights into the process structure, optimum sequence of parameter decisions, iterative cycles and concurrency in the process. A knowledge management framework for parameter-based DSM applications is proposed and the application of the framework is demonstrated through a real life building design problem.

summary This paper presents a distributed and blended model for a virtual design studio and demonstrates the application of the model in a real-life case study. An empirical survey revealed that the proposed model was well-accepted by the current generation of architectural students. The complementary use of the tools with different representational capabilities and synchronization modes enabled effective learning processes. The study also suggested that characteristics of architectural education might entail customization in online and blended learning in several ways.

summary Outcomes of individual differences of learners are rarely discussed in CAAD education. This paper investigates interactions between architectural students’ cognitive styles, as measured by Riding’s Cognitive Styles Analysis, and their performance in computer aided drafting and design processes. An empirical research revealed that Imager students outperformed Verbalisers in both drafting and creativity scores. Technical quality scores were found to be independent from cognitive styles. Contrary to the assumptions of design theory, Wholist students did not perform better than Analytics in design. The study suggests that examining the cognitive styles of students in CAAD education deserves attention and may facilitate for learning.

summary A knowledge based computer-aided architectural design system (KB-CAAD) for the schematic design and evaluation of passive solar buildings is presented. The presented tool is based on the integration of knowledge based and procedural simulation methods with any available CAAD system for building representation. The knowledge base contains the heuristic rules for the design of passive solar buildings. Whenever possible, the knowledge base guides the designer through the decision making process. However, if 'rules of thumb' are not acceptable for the particular design problem, the KB-CAAD tool guides the architect towards the optimal solution, by using a procedural simulation model. It is demonstrated, through a case study, that the proposed knowledge based design system not only leads to the design of better solar buildings, but that it takes less time and man-power to introduce the geometrical data that would be needed for a regular non-solar building representation

summary As one of the domains of urban planning and design, that of green space is lagging behind in terms of the use of advanced computer technology, mo dels and design methodology compared to, for example, retail and transportation planning. However, recently, there is some evidence of the development and testing of tools such as visualization, GIS and conjoint analyses in this area, although not of more integrated Decision Support Systems. The purpose of this study is to outline ideas and needs for thedevelopment of a Decision Support System for the planning and design of green space. The objective is to provide planners with an integrated framework for the provision and management of these parts of urban areas.

summary The paper considers some of the lighting simulation instruments at present available to architects for lighting design. We study the usability and accuracy of various systems, scale models, numerical simulations, rendering programs. An already built environment is the reference comparison for the accuracy of the simulation systems. The accuracy of the systems is evaluated for respectively quantitative simulation and qualitative visualisation. Quantitatively, the programs compute photometric values in physical units in a discrete number of points of the environment. Qualitatively, the programs generate images of visible radiation comparable to photographs of the real environment. They combine calculations with computer graphics, that is, they translate numerical values into images.

source Automation in Construction 5 (5) (1997) pp. 379-391
summary This work presents a tool for analysing the figurative structure of architectural façades. The procedure begins by singling out the elementary shapes which make up the façade image; it detects and identifies them as "area objects", even if present in combination in virtual or mental form and groups them into classes of equal objects. A second step is the analysis of the inner structure of the classes: equidistant, arithmetical and geometrical sequences, or alternate distances are distinguished. The procedure ends by singling out the symmetries which structure the façade image and displaying them, pointing out their implied hierarchy through a thickness differentiation.

summary The research presented is about digital revolution in architecture, which has contributed to the birth of new figurative trends. The work was conducted through the definition of a framework to identify and classify architectural design elements that should be attributed to the methods and techniques of design computing, then applied to sixty prominent recent architectures which are acknowledged products of digital means. The early results suggest that a new era is coming, where the conceptual starting point of designers is often born in the digital space, taking advantage of the augmented representation skills to control and manipulate form. We will also do an overview of these new architectural trends, discussing both causes and cultural roots and identifying eventual criticisms and further developments.

summary Besides design theory and practice, curricula of architectural students should include some experiences referring to professional situations. Among these experiences, Collaborative Design is nowadays somewhat frequent. It is normally practised by large professional studios, using expansive software which is beyond what they can afford on average. Much academic research on the topic has also been carried out often resulting in the proposition of new and too complex description models of the building object. We think that students should instead get acquainted with such a design process: an experience has been planned and carried out in our Department for the purpose of practising the possible paradigm in a more ordinary context. Its purpose was threefold. First, making the students grasp the method’s potentialities and learn the right approach. Second, testing the practical suitability of the most widely used software. Third, comparing their relative efficiency. The software we used was: Architectural Desktop, AutoCad Revit, ArchiCad for Teamwork. We focused special attention on how representing and managing restraints, since they are the main source of conflicts. This was the hardest topic to manage. The results were partly positive inasmuch as the experience showed that it could be possible to adopt the Collaborative Design paradigm which is also used in the AEC field. The drawbacks emerged from the analysis of non-dedicated software are: a relative slow process for the lack of certain specific tools; a subsequent necessity of integrating them with different communication software; the difficulty of managing hard and soft restraints. However, in the final analysis, the experience can be considered as positive.

summary A paper, a description of a software application is given, which allows to generate tridimensional models of buildings, directly inside a geo referential context, following a parametric approach, in which the volume of the building is put in direct relation with forces/law bonds emerging from the urban context. The user is, therefore, able to interactively operate within a project process, in which, by changing the parameters values and by verifying in real time, the results of the changes, he/she is able to evaluate all possible infinite scenarios. The system, thought for Trento’s (Italy) urban context, may also be applied on other cities.

Those constraints may be regarded as force fields with a specific spatial dimension. The system allows user, through implementation of specific generative procedures, to manage interactive architectural design processes. The designer is able to explore all possible infinite scenarios and the various possible design alternatives, by changing the parameters values and verifying in real time the results of the changes.

summary The final configuration of the architectural shape is deeply conditioned by all constraints that the environmental context imposes. These, duly codified, can therefore generative elements that can be managed by the designer. Following a parametric approach, the architectural envelope is directly related to the constraints emerging from the urban context. In this paper we present the development and implementation of an application, which allows to generating three-dimensional models of buildings, directly within a three-dimensional geo-referenced environment. The application offers the user many innovative suggestions, associating the modeling ability, typical of the CAD systems, to the opportunity offered by the geo-referenced systems, to evaluate in real time the impact of the buildings directly on its environment, within which it can be generated and manipulated. The designer is able to explore several alternative solutions, according to formal requirements and style preferences. Three experiments are presented for different urban scenarios.

summary Today’s explosive developments in digital technology have also affected architecture and urban landscape. The new possibilities opened up by digital simulation have led to an increasingly strategic approach to planning, an approach based on generating scenarios, which thus represents a radical departure from traditional planning. But, up to now, what is the prevalent trend in architecture? Can we talk yet in term of language? Or have the extreme freedom in design destroyed the style? In this paper we present an analysis of the contemporary architecture, strongly influenced by digital technologies, through an objective analysis of several case-studies and we show the first result of this in progress research.

summary Two innovations have more deeply changed the building process: the operational continuity of the design and construction phases and the software allowing not only the representation but also the autonomous creation of complex shapes never before thought, just because they could not be represented. This last innovation introduce to a “Performative Architecture” that addresses to emerge a new kind of architecture. Building performances (structural, environmental, energetic) are guiding design principles, adopting new building performance-based priorities for the design of cities, buildings and landscape. This emerging architecture places broadly defined performance above form making; It utilises digital technologies of quantitative and qualitative performance-based simulation to offer a comprehensive approach to the design of the build environment. Some aspects of “Performative Architecture” theories are critically examined and we report two experiments made using these procedures. The results try to give a contribution to detect some misunderstandings in relation to recent building projects shown.

source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 404-409
summary The global envelope to day focuses on it a lot of attention from architects, progressively replacing the classical concepts of wall and roof. It is a complex component, entrusted with the delicate goal of mediating between exterior and interior space, between a space boundary and a bearing structure. Its main parts are the glass wall, a substructure resisting the loads and transmitting them to the bearing structure, and the connection of the two. The latter, in turn, comprises a fitting and a bracket. The set of relationships between these components and sub-components needs the control of many conditions of consistency. The tool presented is an Assistant performing just this task helping the designer to select in each project situation the best couple of two main envelope components: fitting and bracket. The Assistant structure lends itself to implement an intelligent commercial product catalog. It seems also fit to manage component selections strongly conditioned by consistency constrains between collaborating elements.

summary The paper explores innovative methods of navigation for experiencing and spatial comprehension of complex 3D digital environments. Common navigation modes of digital environments are difficult to learn and use within complex multi level digital models and often result in the viewer becoming disoriented or stuck. By drawing on concepts from computer gaming and spatial way finding this research will explore intuitive navigation systems. These systems enable the user to engage and experience the digital space much more profoundly than current CAD and BIM model viewing software. The paper demonstrates these navigation spatial cognition systems through three case studies.

summary How do we know what we are looking at while viewing inside Building Information Modelling (BIM) models? Current architectural software typically provides disconnected methods of aiding spatial cognition. There is a strong history of navigation tools developed for controlling our exploration and movement in BIM models, a study by Ruby Darken and John Sibert (1993) found these tools had a strong influence on people's behaviour and understanding of digital space. People perceive and navigate space differently depending on their individual experience with a BIM model, designers and architects build up a detailed cognitive map during the design of a project, while other people have a less detailed comprehension of a project, having only been exposed to select views. This paper will outline key strategies to improve how people comprehend digital space, supporting people in understanding distance and size while inside BIM models. Three design research projects will be presented. The result of the projects define three strategies; Architectural wayshowing, interior-aware transitions, and distance confirmation. Architectural wayshowing needs to be implemented during the design phase, while the remaining two need to be introduced into BIM editing and viewing software.

The two Case-Studies will present, fi rstly a method for dealing with large amounts of component instantiations and second with the economical delivery of complex project geometry through panelling. Both projects use design technology as a strategy for the integration of specialized knowledge and trades, through an effective use of information technology. The Case Studies will present the development of the Gridshell Digital Mock-Up of the Yas Island Marina Hotel in Abu Dhabi designed by Asymptote Architects and secondly the Museo Soumaya facade system in Mexico City designed by Fernando Romero LAR. This document will report the development process for obtaining relevant construction information, essential for the assembly of the facade systems by a third-party sub-contractor in support of the facade system coordination. The report concludes on the implementations of bespoke tools in support of the coordination and geometry description tasks. The tailored tool making process extends the parametric modelling system Digital Project™ in the design support role of obtaining aesthetically pleasing decompositions of the buildings Master Design Surface MDS into feasible constructible components.

title Component-based architecture for online collaborative disaster relief mission planning environments
source CIDAC, Volume 3 Issue 2 May 2001
summary International disaster relief mission planning situations involve geographically dispersed participants working in a stressful environment towards a common goal. When a large-scale disaster occurs, issues such as search and rescue, survivor relocation and infrastructure rebuilding need to be addressed in a short amount of time. Several constraints exist in this environment such as cultural differences among the relief agencies and the need for flexibility to handle changes in the situation. These constraints lead ot the need for a complex collaboration system which includes support for meeting protocol enforcement, session logging, multiple device access and reliability during periods of highly unstable network conditions.   A component based collaboration infrastructure to support multi-device web-based collaboration sessions has been designed to address such requirements. The system components include a data repository, a collaboration manager and an information policy enforcer to address such constraints. The system can support communcation applications like simulation systems, GIS mapping and resouce management. To support such a wide range of applications and provide access to their data from various hardware devices, the design of the system developed in this research effort is applicatin and configuration neutral for greatest flexibility and applicability.

source Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 114-124
summary Studies of historical architecture and urban contexts in preparation for contemporary design interventions are inherently rich in information, demanding versatile and efficient methods of documentation and retrieval. We report on a developing program to establish a hypermedia authoring approach to collaborative contextual modeling in architecture and urban design. The paper begins with a description of a large-scale urban history study project in which 95 students jointly built a physical model of the city center of Sheffield as it stood in 1900, at a scale of 1:500. Continuing work on the Sheffield urban study project, it appears to us desirable to adopt a digital approach to archiving the material and in making it both indexible and accessible via multiple routes. In our review of digital models of cities, some interesting yet unexplored issues were identified. Given the issues and tasks elicited, we investigated hypermedia authoring in HTML and VRML as a designer-centered modeling methodology. Conceptual clarity of the methodology was considered, intending that an individual or members of design groups with reasonable computing skills could learn to operate it quickly. The methodology shows that it is practicable to build a digital contextual databank by a group of architecture/urban designers rather than by specialized modeling teams. Contextual modeling with or without computers can be a research activity on its own. However, we intend to investigate further how hypermedia-based contextual models can be interrelated to design development and communication. We discuss three aspects that can be explored in a design education setting.

summary The paper presents the development of an experimental Web-based design environment called Townscaping to be used at the conceptual stage of architectural and urban design. Inspired by Gordon Cullen's seminal work on Townscape (1960's-1970's), the idea of Townscaping is to explore how 3D digital sketch design tools could be developed to operate in connection with a dynamic virtual city system under a user's direct control. A prototype of Townscaping has been designed and implemented on the basis of an existing dynamic virtual city system. In Townscaping, a set of tools is provided for users to create and edit 3D graphic elements to be positioned directly onto the user-specified virtual city models. One of the key features of Townscaping is to enable sketching while navigation: designers can perform sketch design and gain immediate visual feedback while navigating the 3D virtual city models to any viewpoint at any moment. The current study suggests that it is feasible for virtual city models to serve as interactive urban contexts for 3D sketch design. Townscaping is considered primarily a research platform with which we are interested in investigating if designers' engaging in 3D space conceptions may be enhanced through interacting and sketching with virtual townscapes.

title Exploring communication in collaborative design: co-operative architectural modelling
source Design Studies Vol 15 No 1 January 1994, pp. 19-44
summary An exploration of communication in collaborative design from the perspective of co-operative architectural modelling is reported. The objectives and problems of communication in collaborative design are described and anaysed by viewing design as, basically, disciplines of modelling complex objects. Three cases of teamwork in architectural modelling are studied, each demonstrating a rich and informative approach to collaboration. Looking at the cases from the co-operative modelling perspective, important conditions for communication are observed: firstly, the participation and co-ordination among heterogeneous systems of representation and action that individual members of a design team work with; and secondly, the interconnection between common goals shared by all participants and domain-oriented goals pursued by individuals. In exploring how the conditions were met, it was found useful to characterize communication in terms of the inter-relations between common images and distributed design developments. Two generic patterns of communication in collaborative design were found, which suggest two alternative conceptual frameworks for developing computational representations.

summary In this paper we describe our current research into an object-oriented approach to the recording and managing of design decision-making in the processes of building design. The Advanced Design Support for the Construction Design Process (ADS) project, funded under the Innovative Manufacturing Initiative by the UK Engineering and Physical Sciences Research Council (EPSRC), aims to exploit and demonstrate the benefits of a CAD-based Design Decision Support System. The research focuses on how to provide designers with tools for recording and managing the group dynamics of design decision making in a project's life time without intruding too much on the design process itself. In collaboration with Building Design Partnership, a large multidisciplinary construction design practice, we look at design projects that require decision-making on an extraordinarily wide range of complex issues, and many different professional consultants were involved in making and approving these decisions. We are interested in developing an advanced CAD tool that will facilitate capturing designers' rationales underlying their design decision making throughout the project. The system will also enable us to explore how a recorded project history of decision-making can be searched and browsed by members of the project team during and after design development.

title On an alternative framework for building virtual cities: supporting urban contextual modeling on demand
source Environment and Planning B: Planning and Design, Vol. 29, pp 87-103, Jan 2002
summary For various purposes, virtual city applications have been developed around the globe to provide users with online resources and services over the Internet. Following our research on the Sheffield Urban Contextual Databank (SUCoD) project, this paper presents an alternative framework for building virtual cities, which goes beyond conventional static urban modelling. A three-tier system framework is described in conjunction with the design and implementation of the SUCoD prototype. We demonstrate SUCoD's novel functionalities by showing that complex urban contextual information sets, including three-dimensional interactive models, multilayer interactive maps, and hypermedia documents, can be retrieved dynamically by user-specified urban contextual attributes, spatial loca- tions, and boundaries. The three-tier framework also facilitates system development in an extensible way, allowing continuous parallel extensions of system functionalities, user-interface components, and contextual data resources. SUCoD's dynamic capabilities are considered crucial in its future uses for urban contextual modelling on demand in relation to the past, present, and future of the City of Sheffield.

summary This paper presents our current development of the Sheffield Urban Contextual Databank (SUCoD) prototype that provides users with a Webbased interface for dynamic retrieval of architectural and urban contextual information of the city of Sheffield. In comparison with past attempts of building Virtual Cities accessible over the Internet, we have experimented with a different system architecture capable of generating VRML models and other related documents on the fly according to users' requests. Through working examples, we describe our methods of implementing the data communications between Java applets and Common Gateway Interface (CGI) scripts. The SUCoD prototype has been developed to explore and demonstrate how user centred dynamic retrieval of urban contextual information can be supported, which we consider a user requirement of primary importance in its future use for collaborative design and research relating to the city of Sheffield.

summary Work on a methodology that attempts to deliver a dynamic urban information system for visualising city in change is presented. We have developed a Multi-tier Extensible platform for Dynamic and Interactive Urban Modelling (MEDIUM) in connection with a large-scale historical urban study programme that investigates the history of the City of Sheffield. The MEDIUM platform shows some new properties that could address the limitations observed in conventional static urban modelling. We consider that 3D virtual city models can be created along a chronological axis and the time dimension of each model segment can be registered in such a way that the 3D models of different times can be brought together under a unifying visualisation platform. This will allow a visual understanding of how a city may have evolved to develop. To date, we have applied the MEDIUM platform to real city datasets and produced examples that allow us to examine what effects of urban visualisation could be achieved through the dynamic user-centred approach.

summary Following our previous research on developing a dynamic virtual city system (Sheffield Urban Contextual Databank, SUCoD), the paper reports on a study of applying the virtual city resources to an undergraduate urban design course. The study focuses on how the multi-dimensional and multiple types of urban contextual data can be used by student designers directly for urban visual analysis and design development. A link is made with the Serial Vision in Townscape first proposed by Gordon Cullen, which sets out an experiential approach to how a living city environment should be read and understood. Drawing on the project works produced by the students, some patterns of generating urban narratives and 3D spatial designs were observed. Although the current experiment with SUCoD is limited in terms of data scope and modelling capabilities, it reveals a future direction to follow that can turn conventional virtual cities into Web-based online services capable of supporting urban design analyses and syntheses directly.

title uCampus: Can an open source 3D interactive virtual campus modelling platform support institutional learning and innovation?
source International Journal of Architectural Computing vol. 9 - no. 3, 303-324
summary This paper reports and reflects on the key findings from the UK JISC funded weCAMP-uCampus project undertaken at the University of Sheffield in which a Web-based 3D interactive campus visualization modelling platform was developed and deployed using the latest Java and XML-based open source technologies. The project evolved rapidly along three strands of development on software design, content generation, and user/stakeholder engagement. One of the key outcomes is a novel approach to visualising large complex datasets in conjunction with multi-scale and multi-layered 3D campus modelling. To test the adaptability of uCampus, the Augustine House Experiment was later carried out in collaboration with the iBorrow project based at the Canterbury Christ Church University campus. The question on the prospect of uCampus to support learning and innovation at an institutional level is discussed by revisiting the earlier works of the Oregon Experiment and the Seeding-Reseeding Meta-Design Framework.

summary In this paper, we present LiQuID, a tool for seeing lighting quality in design. Photographs are useful vehicles for both describing and making assessments of architectural lighting systems. A significant barrier to using photographs during the design process relates to the sheer volume of renderings that needs to be analyzed. Although there have been efforts to produce novel visualization systems to manage large sets of photographs, this research aims to reduce the complexity by classifying data into representative prototypes. A hypothetical case study is discussed.

summary A divide-and-conquer algorithm is presented for finding all the intersection lines between two B-spline surfaces. Each surface is organized as an n-branch tree. For each intersection line, an initial point is detected after a depth-first search along one tree, i.e. the host tree. Extrapolation methods are then used to trace the entire length of the line, thus the line appears naturally in a continuous form. Efficiency of the algorithm is achieved by employing of an adaptive division strategy and by the careful choice of the representation basis of the patches on both surfaces

title A Design Interaction Tool That Adapts
source VDM Verlag
summary Despite different computerised approaches have been hardwired to solve various complex practical problems; few are founded on an adaptive paradigm such that a computational model interacts with its environment, loosely wires itself and learns from experience like humans do. This book presents our attempt to craft a computational model that learns from interactions and adapts based on its experience. We draw ideas from cognitive psychology in relation to human experiential learning, particularly the notions of ?situatedness?, ?constructive memory? and ?concept formation?. When applied to design activities, which are intrinsically dynamic and interactive, this model constructs concepts from interactions between the agent, the design problem and the use of the design tool. Such a design interaction tool generates knowledge based on the agent?s grounded generalisation from contextual information in a situated manner. Adaptive behaviours emerge from coupled interactions of the system from a macroscopic and a microscopic level. This book is suitable for researchers and students interested in pursuing computerised approaches based on cognitive science and natural computing.

title Machines’ Perception of Space: Employing 3D Isovist Methods and a Convolutional Neural Network in Architectural Space Classification

summary Simple and common architectural elements can be combined to create complex spaces. Different spatial compositions of elements define different spatial boundaries, and each produces a unique local spatial experience to observers inside the space. Therefore an architectural style brings about a distinct spatial experience. While multiple representation methods are practiced in the field of architecture, there lacks a compelling way to capture and identify spatial experiences. Describing an observer’s spatial experiences quantitatively and efficiently is a challenge. In this paper, we propose a method that employs 3D isovist methods and a convolutional neural network (CNN) to achieve recognition of local spatial compositions. The case studies conducted validate that this methodology works well in capturing and identifying local spatial conditions, illustrates the pattern and frequency of their appearance in designs, and indicates peculiar spatial experiences embedded in an architectural style. The case study used small designs by Mies van der Rohe and Aldo van Eyck. The contribution of this paper is threefold. First, it introduces a sampling method based on 3D Isovist that generates a 2D image that can be used to represent a 3D space from a specific observation point. Second, it employs a CNN model to extract features from the sampled images, then classifies their corresponding space. Third, it demonstrates a few case studies where this space classification method is applied to different architectural styles.

summary The day is not far off when autonomous, artificially intelligent agents will be employed in creative industries such as architecture and design. Artificial intelligence is rapidly becoming ubiquitous, and it has absorbed many capabilities once thought beyond its reach. As such, it is critical that we reflect on the relationship between AI and design. Design is often tasked with pushing the envelope in the quest for novel meaning and experience. Designers can’t always rely upon existing models to judge their work. Operating like this requires a curious and open mind, a willingness to eschew reward and occasionally break the rules, and a desire to explore for the sake of exploring. These behaviors fly in the face of traditional implementations of computation and raise difficult questions about the autonomy and subjectivity of artificially intelligent machines. This paper proposes computational play as a field of research that covers how and why designers roam as freely as they do, what the creative potential of such exploration might be, and how such techniques might responsibly be implemented in computational machines. The work argues that autotelism, defined as internal motivation, is an essential aspect of play and outlines how it can be incorporated in a computational framework. The work also demonstrates a proof-of-concept in the form of an autonomous drawing machine that is able to plot a drawing, view the drawing, and make decisions based on what it sees, bringing computational vision and computational drawing together into a cyclical process that permits the use of autotelic play behavior.

summary Immersive virtual environments have received widespread attention as providing possible replacements for the media and systems that designers traditionally use, as well as, more generally, in providing support for collaborative work. Relatively little attention has been given to date however to the problem of how to merge immersive virtual environments into real world work settings, and so to add to the media at the disposal of the designer and the design team, rather than to replace it. In this paper we report on a research project in which optical see-through augmented reality displays have been developed together with prototype decision support software for architectural and urban design. We suggest that a critical characteristic of multi user augmented reality is its ability to generate visualisations from a first person perspective in which the scale of rendition of the design model follows many of the conventions that designers are used to. Different scales of model appear to allow designers to focus on different aspects of the design under consideration. Augmenting the scene with simulations of pedestrian movement appears to assist both in scale recognition, and in moving from a first person to a third person understanding of the design. This research project is funded by the European Commission IST program (IST-2000-28559).

title The Emperor's New Mind. Concerning Computers Minds, and the Laws of Physics.
source Oxford University Press
summary The Emperor's New Mind, physicist Roger Penrose's 1989 treatise attacking the foundations of strong artificial intelligence, is crucial for anyone interested in the history of thinking about AI and consciousness. Part survey of modern physics, part exploration of the philosophy of mind, the book is not for casual readers--though it's not overly technical, it rarely pauses to let the reader catch a breath. The overview of relativity and quantum theory, written by a master, is priceless and uncontroversial. The exploration of consciousness and AI, though, is generally considered as resting on shakier ground. Penrose claims that there is an intimate, perhaps unknowable relation between quantum effects and our thinking, and ultimately derives his anti-AI stance from his proposition that some, if not all, of our thinking is non-algorithmic. Of course, these days we believe that there are other avenues to AI than traditional algorithmic programming; while he has been accused of setting up straw robots to knock down, this accusation is unfair. Little was then known about the power of neural networks and behavior-based robotics to simulate (and, some would say, produce) intelligent problem-solving behavior. Whether these tools will lead to strong AI is ultimately a question of belief, not proof, and The Emperor's New Mind offers powerful arguments useful to believer and nonbeliever alike

title Services in Digital Design: new visions for AEC-field collaboration
source International Journal of Architectural Computing vol. 7 - no. 3, 459-478
summary The objective of this paper is to describe contemporary digital building design from a service provider aspect. The constrained framework of this work is digital architectural design practice. When design is seen in the context of the AEC field, a process oriented approach is commonly used in describing collaboration and evolutionary progress of the design work as a project. Design projects are scheduled chains of activities which result in design delivery or actual physical buildings as the end products of the project. Recently developments in building information modelling (BIM) have presented fundamentally new ways for collecting, exploring, and sharing design information. This study develops the novel digital approach: BIM as design services. The key finding of the study is that parts of the design domain can be described as services in the changing digital environment. The scientific contribution of this paper is in describing contemporary digital design practice with an alternative service approach. A framework for such services is also presented. This work will expand the authors' contribution to research on preliminary architectural design using building information models.

title Architectural-IT and Educational Curriculumns - A European Overview
source International Journal of Architectural Computing vol. 1 - no. 1
summary The paper summarizes the analysis of data on european architecture schools, collected in the eCAADe-conferences during the 1990s. Computer-Aided Design has developed into architectural information and communication technology (ICT), to become commonplace in architectural education. However, the general held views on new media use in the schools seems to be slightly optimistic. On the other hand, the invisible more common ICT use (writing, surfing, emailing) accounts for a lot more of the volume of activity than generally appreciated. The major hardware platform in european architecture schools is PC/Windows (90-95%) with Linux and Unix commonly used in servers (25-35%). Macintoshes are also widely used (50-55%). MS Office (90-95%) and PhotoShop (85-90%), are used widely in the schools. The Graphic and DTP tools PageMaker, QuarkXpress, Illustrator, Freehand are also common (30-50%). AutoCAD is the market leader in CAD platforms (80-90%), followed by ArchiCAD. MicroStation/Bentley also has a significant presence in the schools (35-40%). 3DStudio is the most common 3D-modelling tool (80-85%), followed by formZ (35- 40%). Less common (15-25%) are Rhino, Maya, Alias, Lightscape and Radiance.

summary Several common phrases, such as “information society” or “virtual reality” point out the fact that information technology, digital tools and numerous different services via various communication networks have become crucially important factors of our western lifestyle and living environment. The trends of the society reflects naturally the working environments of the construction field, architectural discipline being amongst them. It is almost inconceivable to even imagine an architect without computer-based tools anymore. This evolutional development process has, from historical perspective, only recently started. The process is constantly evolving and rapidly increasing our possibilities to use and enjoy these modern digital fruits. The sometimes unpredictable and rapid changes in our working environment should make architects nervous about the impacts of the changes. All those delicate methods and collective traditions of the several thousand year architectural discipline(!), just simply cannot be transferred into the digital realm in a few decades. Researchers and teachers should very carefully, but still open mindedly, critically explore, analyse and adjust the so-called “modern technology” into the world of architecture, construction, design, planning – and education. We are not just “endusers”, It is we, in fact, who should define what, where and how are we willing to use it(IT). The value of information is constantly growing in our society, and in the future it will evidently be even more so. The value of information is quite hard to define with measurable or agreed concepts, but information evidently contains value-factors. The information which the architects are creating, modifying and manipulating, contains essential and valuable core data concerning the whole built environment of our society. It affects the physical surroundings of our society, in which we will be living for decades – hence, the information has a historical basis. The architectural core information also very strongly affects the quality of life of our fellow citizens – consequently, it has deep social meaning. The essentials of architectural information relies on the tradition of centuries – hence, it clearly has acknowledged cultural values, which are also extremely difficult to quantify. So how could architectural information be described? The information covers a wide range of heterogeneous concepts, items, values, methods, tools, materials, true facts, rumours, intuition and knowledge, plus a multitude of yet undefined or unpredictable factors, which still have to be watched and prepared for. Since the information deals with common and general subjects, it should also be described with common and general concepts. On the other hand as the information is also concerned with the minutiae of specific projects, the architectural information should also be described with well identified and unique entities. With our digital tools we handle all information – including architectural – more and more digitally. We have to handle and manipulate information currently as digital data, which could be understood the ”raw material” of architectural information. Digital data becomes valuable information, when some kind of meaning or purpose to somebody can be attributed to it. In the early gloomy days of ”digital architecture” in the 1960’s and 1970’s, researchers tried to describe architectural artefacts and even design process mathematically. The details of architectural information were quite difficult to describe with binary alphanumeric information of main-frame machines. The architects’ tools development then led to a trend where architects could better represent and visualize the design objects digitally. The widespread and common use of 2D-drawing and 3D-modelling tools is still a very strong trend within our discipline. In fact it is “the way” the majority of architectural information is managed today. During the last 15–20 years, so-called conceptual modelling or product data modelling, done in various technical and construction field research units worldwide, has from one viewpoint clarified the basis and essence of architectural information. Hence, it’s not only CAD-software application development, but also elementary and theoretical research that gives us valuable help to survive among the ever growing seas of terabits of data in the future to come. Architectural information is something that simply cannot be described just with DWG-drawings or dummy scanned photographs any more. Although drawings and photos may contain very important bits of architectural documentation, we need ntimes more “complexity layers”, concepts and tools to manage and understand the essence of architectural information today. A proper way to manage the data we are working with, has to cover the whole architectural discipline. The methods and tools also have to be valid and flexible for several decades in the future.

summary The subject of computer-aided building modeling is often discussed in various contexts, sometimes without clear explanation of what is modelled. Usually modeling refers to 3-dimensional geometric modeling, but nowadays also conceptual modeling and mathematical simulation aspects are more and more evident. Building modeling should though be considered more widely than just plain geometric visualization. This paper establishes one common framework for discussion about different building modeling viewpoints arranging discipline viewpoints, approach methods, existing standards and application tools within one context. Although several viewpoints are declared conceptual building modeling is regarded the main emphasis of this paper, since it definitely will be one of the key issues in developing methods and tools for computer integrated construction (CIC) in the future.

source Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 161-166
summary This approach sees traditional video endoscopy and computer-based modeling techniques as two methods whose combination gives advantages for both. Endoscopy and computer based tools are not alternative nor rival techniques. New digital visualization possibilities are available within the context of CAD- systems. High-end and more expensive visualization has gained influence from commercial advertizing and also from entertainment industry. Traditional endoscope video has longer historical background and it’s roots are in model photography, model-based simulations and video techniques. The main focus of this paper is to describe Tampere architectural department’s computer based visualization facilities briefly with two cases studies. Our status and resources in traditional simulation have been rather good since mid 70’s, and now when also the basic digital facilities (word processing & CAD) exist, it will be our next challenge to deepen and develop the variety of available simulation methods, equipment – and naturally knowledge in combining them.

source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 347-354
summary A brief historical analysis followed by some possible future scenarios The influence of CAD – nowadays more correctly stated with CAAD meaning architectural CAD – has been more and more evident in the university level architectural education. The development process of architectural CAD-courses and wider CAD-curriculums could, at least in Scandinavian countries, be described and simplified with a couple of development steps analyzed here, to give the starting point. And since the process of educational evolution will naturally keep on developing in the future also, some possible future paths concerning both CAD-equipment, CAAD-education and more traditional architectural curriculumns, are described here after the historical analysis. Following commonly used futures studies methods, my intent is not to predict the future, but to give several probable future choices, of which some might come true, and some might not. Some of the paths are evident, some are ideal and some may cause also negative effects. The future of architectural education and CAAD as part of it will certainly appear somehow, very possibly somewhere in the middle of these presented paths. The aim of this presentation is to give the architectural education community – the schools and faculty – a wide perspective view to analyze and plan their local course structures also for the future. The future possibilities are presented here, so that the schools can prepare for the forecoming future changes in their workin environment. Finally, the future will appear the way we will create it.

title Top 5 Themes to Promote Architectural Information Technology and Top 5 Obstacles to Decelerate it
source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 6-10
summary The objective of this paper is to scan a few interesting themes, features and ideas of current information and communication technology (ICT) to promote their wise use within the fields of architectural practice and architectural education. The core idea is to prepare for the future by understanding the future relevance of the dominating themes. The meaning and significance of the selected and presented common ideas is evaluated to strengthen a realistic future basis for the design discipline. The author finds organizing, structuring and sharing architectural design data with digital tools the most future-relevant ICT-theme, that should be supported with R&D-activities and taught in architectural ICT-education. The obstacles of digitalization to produce negative impacts to architectural profession seem to be of mental nature rather than technical. The human mind, juridical agreements and long-lived design traditions are possibly the most threatening and restrictive obstacles in the future. The selected top 5 methods in evaluating existing trends and features has been used for instance in futures studies as one systematical approach to chart history and current times as informants of the future (Bell, 1996). A pragmatic and personal approach has been used in selecting the themes.

summary The main objective of this on-going post-graduate study, is to describe the role of ”modern digital information technology” within the educational curriculumns of European schools of architecture. Information technology understood in its widest meaning. Essential questions of the study are: [1] How widely the digital media, tools and methods have been adopted in the education? [the volume] [2] In what ways information technology is utilized in architectural education of our age [the methods]. [3] What kind of changes the digital media in fact has caused to the architectural working and educational environments. The results will be published and “weblished” in the form of searchable public web-databases. The results should contain helpful elementary information for those developing and targeting the future architectural education of “the digital age” The research study was started in April/2002, and will [hopefully] reach the conclusion during the year 2002.

source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 601-606
summary The paper documents the findings of the post-graduate study carried out among the 180 European schools of architecture in more than 30 countries during 2002-2003. The objective has been to describe the role of ""modern digital information technology"" and to give an understandable and measurable overview the current architectural education and its relation with ICT and CAAD. The study material has been collected with a web-survey, with questionnaires to eCAADe-conference participants in Helsinki 2001 and Warsaw 2002, and with direct email-contacts to schools’ key-persons. Computer-aided design has developed into architectural information and communication technology (ICT), to become the main tool of the majority. The general image of new media use in the architectural schools seems to be slightly too positive. The invisible or ”normal” ICT-use - writing, surfing, emailing - has a lot more volume than documented. The major hardware platform in european architecture schools is PC/Windows (90-95 %), Linux and Unix are used also commonly (25-35 %). Macintoshes are also used much more widely within architecture (50-55 %) than within the common computing platforms. MS/Office (90-95 %) and PhotoShop (85-90 %) are obviously also used widely in the architecture schools. Graphic tools PageMaker, QuarkXpress, Illustrator, Freehand are common tools for architecture students (30-50 %). AutoCAD is ”the marketing leader"" in architectural platforms (80-90 %) followed by ArchiCAD (60-65 %). MicroStation/Bentley has also a remarkable volume in the schools (35-40 %). 3DStudio is the most common 3D-modelling tool (80-85 %), followed by formZ (35-40 %). Slightly less volume but still remarkable (15-25 %) have Rhino, Maya, Alias, Lightscape and Radiance.

summary This paper describes and analyses the impacts of the current Finnish building product modelling methodology on the building process and on construction field organizations. The objective is also to recognize and monitor changes in the design and construction environments as well as in the software platforms. In Finland building product modelling has, after 10-15 years of preliminary research, evolved into a piloting phase where the developed modelling methods are currently tested in real-life projects. One quite possible - and even more desired - future scenario is that building product modelling will become an essential collaborative working platform for building projects within the next 10 years.

source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 252-260
summary The architectural working environment has changed during the last 30 years more than ever before. Most of the changes have been related with information and communication technologies (ICT). Architectural working methods and tools have changed profoundly, when CAD has replaced more traditional methods and tools. Communicative working environment and document management within design & construction has also been changed to digital, meaning email and project webs. Completing a traditional architectural profile of the 20th centrury, a drawer-designer, contemporary communicating and managing skills plus mastering ICT are needed today to operate modern architectural practise properly. The objective of this study is to create a change-oriented understanding of the contemporary architectural profession concentrating on architectural information management. The first phase, a literature study, will be followed by interviews and case-studies, to examine three hypothetically different periods of time: a) 1980-85 the era before CAD, the last days of hand-drawing, b) 1993-98 the era of digital drawing, the expansion of architectural CAD, c) 2000-05 the rise of integrated and pervasive web-supported digital design. The study will propose new aspects to be included in the modern architectural profile, namingly project coordination, collaborative team-work, design information integration and profound digital content management.

summary This paper examines the meaning of information and communication technology (ICT) for architectural design in early design project phases, with a particular interest in building information modelling (BIM). Contemporary digital design environment, research context and objectives are first clarified, followed by the presentation and analysis of a few BIM-related projects. A key finding is that the architectural working environment, the design methods and the designer's roles have changed in the contemporary project context. Furthermore, other methods and tools are needed in addition to BIM in the early project phases, because it can not solve all required design aspects.

source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 81-88
summary This paper describes and evaluates two recently emerged concepts, Virtual Building Environment VBE and Building Information Modelling BIM, fitting them into the context of contemporary design and construction. Both are elementary concepts in modern digitally “reinforced” design and construction. A case study of cost estimation is presented to illustrate how discipline related issues are currently managed within VBE and BIM. An environmental aspect is presented as a corresponding domain to evaluate the other use cases of building related information. Other similar domains to be evaluated perhaps in further case studies could be the functional user aspect, the project management aspect and the regulating aspect by the society and authorities. A hypothetical assumption is, that methods and technologies which are currently used within VBE and BIM, mainly by designers, can well support various data extractions from BIM-models, but they may not serve all construction process participants in the most beneficial way. Also wider scale building portfolios are requested as conceptual extensions to VBE and BIM. This study is based on ongoing PhD studies on building information modelling and environmental life cycle assessment.

source Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 607-613
summary This paper reports a research study which evaluated the possibilities of building information modelling (BIM) within renovation of buildings of significant architectural, historic or cultural values. Renovation or restoration projects of historic buildings can be more demanding, challenging and complex than traditional renovation of for instance within housing. Objective of this research has been to transfer ICT (information and communication technology) and BIM research findings to historic design practice and true renovation project environments. The concept of building information modelling BIM is a proposed integrative framework for all design and construction project information in digital form. BIM can currently be seen to be in a phase of pragmatic pilot projects in several countries. Nevertheless, BIM has not been tested that much in renovation projects yet, although the importance of renovation and restoration is remarkable within the total volume of western construction sectors. One essential conclusion of this study is, that renovation design work should be started earlier in model-based design projects than in traditional renovation projects. More resources have also to be assigned to earlier design phases, if BIM is intended to be used extensively throughout the project. Another finding is the new concept of an inventory model, which is proposed to be the container for all building inventory, survey and measurement data. Even more so, when significant historic, hence more demanding building renovation is concerned, because there are more needs for various kinds of surveys, accurate data gathering and analyzing queries concerning the project.

summary This paper presents an exploration of movement as a design material to evidence human-machine interaction in an architectural space. An autonomous robotic vehicle with environmental sensory capabilities interacts kinetically with people by recognizing their emotional states from their body postures. A drawing device installed in the vehicle leaves a trace on the floor as a material testimony to the mutual dynamics. The complex yet surprisingly intuitive choreographic interaction of the machine and its social and physical environment blurs the boundaries between drawing, machine, and performance. In general, the project conceptualizes movement as a design material, drawing as a performative action, and social interaction as a physical force, all of which can be enhanced or mediated by digital technologies to produce results with aesthetic value.

summary This work aims to investigate the applicability of 2D and 3D isovists, as well as Visibility Graph Analysis (VGA), for evaluating urban vulnerability to crime. The methodology is based on correlations between number of crime occurrences and measurements of 2D and 3D isovists, and mean values of visual integration (VGA). The 2D isovists were produced through DeCoding Spaces Toolbox for Grasshopper and the 3D isovists were generated by using algorithms within Rhinoceros and Grasshopper. VGA maps were elaborated within DepthmapX. For this study, were selected nine street segments of Boa Viagem, located in Recife-PE, a neighbourhood which is known for high rates of robberies. Although the number of samples is reduced, the results suggest that criminals prefer much more visually integrated spaces with low occlusivity and fewer spatial cavities.

title Speculative cartography and the formation of public interest issues
source SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 1333-1339
summary This work discusses how locative media and the democratization of geoprocessing technologies have reconfigured our experience with the urban space, opening up new territories for the construction of the public. It also discusses perspectives and challenges that speculative practices with locative media bring to disciplines such as design, architecture and engineering, and to the production of more sustainable ways of life. For that matter, this work presents some experiments with locative media and digital cartographies that aim to give visibility to our social relation with the urban space and to support processes of sense-making about issues of public interest.

summary It is well known that Math learning processes common used within elementary school phases are not necessarily competent. Students are rarely capable of relating acquired knowledge with day by day activities and memorizing practices are encouraged by teachers. On the other hand, the use of games during learning development is an important alternative that brings interest, playful and real knowledge of content assimilation. This paper describes how digital fabrication tools were used by students to develop and build game prototypes as an option on Math learning. The experience was accomplished through a Mobile Digital Fabrication Lab as an instrument that brought these technologies to students.

summary Digital Fabrication has been widely used for the production of standardized building components, but not so in the engineered-to-order fabrication strategy, a system in which the customer’s needs are fulfilled in the design stage. Mass Customization meets the demands of a customer at a cost near that of Mass Production. This study presents the current stage of an Action Research dealing with Mass Customization, design and BIM adoption challenges, proposing the adoption of BIM aiming Mass Customization at engineered-to-order systems for Small and Medium Enterprises. It uses Web-based User Interface and Revit and Dynamo models exported to Computer Numerical Control machines.

title Generating Alternatives For Siting Using Genetic Algorithms and Multiple Criteria Decision Techniques
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary It is believed that a fundamental step in the structuring of a siting problem is generating alternati-ves. This task should occur at the beginning of a process for facility location, giving a preliminary insight into the feasibility of the project in the area of concern by identifying a manageable number of feasible alternatives for careful review and consideration. The purpose of this paper is to present a methodology aimed at generating alternatives for siting of facilities taking into account a number of criteria. These criteria comprise environmental, economical and the action's inherent technical aspects. The search is carried out by applying genetic algorithms (GA's) which are natural phenomena based algorithms for optimization and random search procedures. According to the GA's terminology, a fitness function measures the worth of each candidate alternative codified into a chromosome. It was thought that the merging of aspects of multiple criteria theory and genetic algorithms is essential for the problem of generating alternatives in location problems. The aim of this integration is the improvement of the theoretical principles upon which the fitness function is based, leading to the construction of a robust set of alternatives. The paper describes the integration of both multiple criteria theory and GA's and discusses the results.

source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 491-495
summary The design experience referred to in this paper deals with the creative process for developing the pre-design of a new building for the Architecture and Urbanism Department of the Federal University of Santa Catarina / Brazil. The methodological proposition was to develop the design in a collaborative way and to try to use computers from the very beginning of the process. A tri-dimensional computer model was constructed on the sketch phase. Plans, sections and views were generated from this unique 3D model in order to assist development of ideas, coordination and visualization. As soon as the design alterations were defined, the 3D model was updated in order to generate automatic new drawing documents. Due to the number of design team components (8 people) and the high level of design complexity, constant hardcopies were necessary to ease designer’s participation in the idea propositions during meetings.

summary This paper describes the beginning of a project called TEAR_AD: Network for Teaching and Learning Technology in the areas of Architecture and Design. Such project aims to support the problem of Professors, Lecturers, and students lack of knowledge about a whole set of technologies that can turn a project more precise and responsive in terms of constructibility, sustainability and general performance. They have problems in keeping updated about those technologies and, in consequence, do not apply them in their practices. In order to explain the strategic plane of the project, that consists in the first part of the Garrett Methodology for Experience Design, the identification of Personas, representing the target public, the use of the benchmarking to identify possible features to be used in the system, and so on, are described. Considerations about how to pursue the implementation and maintenance of the designed system are outlined.

summary Digital data are the key for the plain utilization of potential already available with geoprocessing technologies. Information that interest urban planners came from several sources and information technologies beside integration and manipulation permit visual investigation of spatial data in diverse aspects, from witch the most evident but not less effective is a map, tool that let us correlate a great variety of qualitative and quantitative data, for organization, interpretation, evaluation, presentation and communication. The work intend to build a urban digital database from Salvador and provide architects, geographers and urban planners a tool to visualize urban information in an easy way. It is structured like a hypermedia atlas using concepts from cartographic modeling. Information is organized in general and specific themes - physical environment, socioeconomic, land use, habitation, infra-structure, etc - that can be visualized alone or coexistent with others themes. Scale of visualization can be various.

summary Before popularity of GIS a map is a tool with two basic functions - storage of spatial data and presentation of spatial information. Now, a digital database store spatial data and cartographic visualization is how spatial information usually is presented. Recent technological development applied to visualization area can increase analyse and interpretation capacity of professionals concern with urban planning, design and management. In other hand, many professionals and students involved with urban studies are not familiar with GIS software and this can limit casual users to access urban databases. One solution is to build software that allows direct visualization of spatial information based in users needs and knowledge. The project discussed in this paper introduces a computer application structured like a hypermedia atlas using concepts from cartographic modelling. The city of Salvador is represented by a model based in a combination of maps, and others images. User composes visualization.

summary An instrument with high data-processing capacity capable of developing design solutions not previously viewed by the human intellect, should not be seen as a mere design tool. In a world encoded by the virtualization of human relations and the definitive change in the relationship between subject and object, it is the role of the architect to understand what would be his true positioning in a shared design process with a computing device. This article intends to be the beginning of a comprehensive research between theoretical and pratical aspects on the relations established between the agents involved in an algorithmic process of creation in architecture.

summary Nature exhibits forms of Vision without need for an eyeball. Brain adaptive abilities generates mental images allow to compensate for the visual stimulus captured through other senses such as touch and hearing. Technological extensions capable of mediating between the environment and the generation of sensory compensations, develop new forms of vision for the human being. This project proposes functional approaches capable of detecting visual elements in the environment that favor the construction of mathematical forms. The capture and processing of images mediated by the support, generate haptic sensory stimuli that performs the act of seeing without the need of eyes.

summary The mediation by Augmented Reality, allows to add layers of virtual information to reality in natural and intuitive ways, guaranteeing interactions in real time and generating new perceptual stimuli not necessarily remitted exclusively to the field of vision. Interaction devices such as fiduciary markers are resources generally associated with RA experience, however these markers of paper-usually turn out to be ephemeral when implementation is done in open spaces and high traffic. The following work presents results in the analysis of materials that guarantee to be ideal for the permanent implementation of markers in pedestrian urban routes.

title Do Intelligent Objects Need Programmed Users?
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 52-55
summary Intelligent objects for daily use offer greater advantages than electromechanical products. However, they need a user whose life is more methodical, programmed and predictable. As de number of services offered in such products increase, their restrictions in their flexibility of use arise. Finally, users adapt themselves to habits that these objects suggest (for better) or prescribe (for worse). However, a paradox exists. What is controversial for a standard user: the increasing passivity justified in the eternal pursuit of comfort, for a disabled person means achieving independence and autonomy. In order to accomplish the revolutionary equity that computer science claims, the possibility of being excluded for economic reasons should not exist. If not, it will increase the fracture between coexistent realities in the same territory. For these reasons, assuming the risk of being considered naive and idealist, we believe that in order to build a better future it is necessary to promote policies that guarantee the access to new technologies for people with low economic means. Together with the consciousness users gain -related to product selection-, it would break the premature discouragement that the markets try to impose, resigning us to an unjustified idea of weakness and submission.

source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 255-266
summary It might seem that architecture has been forced to choose, once again, between two worlds of existence. One of them might be the construction of the tangible, the other, a “formal fantasy” that will never reach a legitimate status among the “tectonic” or the “structural”. This vague spectrum has confirmed the fear of loosing typology as a proof, of loosing a foremost validation for architecture. But one could see the virtual as a possibility to generate a structure of discourses and interactive tactics to reformulate the typological. This meaning that the virtual could transcend the so called “graphic” stigma and actually produce the discourses and spatial strategies to radicalize typology and move towards a radicalization of content.

summary The distinction between the artificial and the natural has been increasingly challenged as a result of advances in genetics, microbiol¬ogy, and robotics. Beginning with the molecular assemblage of organic systems into complex micro-surfaces and structures, and expanding into the realm of the macro landscape, our understanding of the term Synthetic must be revised. What is the relationship between the component (or part) and the whole, when confronted with the Synthetic? Digitally mediated fabrication technologies, combined with a renewed interest in topology and (bio)logical form, serve to challenge our preconceived notions of space and form. This inquiry will attempt to explore the relationship between traditional assemblies produced by hand, and the production of complex forms through digital rapid prototyping. The impact of D'Arcy Thompson's On Growth and Form will be considered both as a historical juncture and a contemporary source of knowledge for the exploration of new assemblages inspired by topology and biology. In particular, the organic micro-surfaces depicted in France Bourély's Hidden Beauty will be explored, in comparison with the mathematical development of organic forms inspired by Periodic Minimal Surfaces. The analysis of emerging forms and assemblages based on the notion of the Synthetic will be compared with the Organic, and considered within the context of twentieth century art and sculpture. An attempt will be made to establish new modes of inquiry for combining digital and physical explorations of space and form, influenced by advances in micro-scale structures, complex surfaces, and the history of organic form in art.

title PolyForm: Biomimetic Surfaces
source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 471-482
summary The evolution of the architectural surface from a static, fixed geometric assemblage to a responsive, biomimetic aggregate surface will be the topic of this paper. The work exhibited has been developed by the author and his students over the last two years, prompted by an interest in robotics, advanced material assemblies, and biomimetics. The work ranges in scope from digital models and simulations to working prototypes and full-scale habitable constructions. One aspect that serves to unite the emerging body of work may be summarized in the prefix “poly” denoting many, or having more than one state or form. Thus the word Polyform begins to suggest the interplay between biomimesis and adaptive surfaces. A similar term is found in the combination of poly and morph:

summary What is the role of Craft, in understanding Bio-Computational Forms & Systems? What is the relation between self-organizing systems & material-component assemblages? ¶ This paper will explore the relationship between material craft, procedure and form, in relation to complex, self-organizing assemblies. A comparison will be made, between (hand) crafted assemblies, guided by physical constraints and procedural methodologies, and digitally mediated fabrication, guided by recursion and algorithmic generative methodologies. ¶ An attempt will be made to connect various scales of making, in terms of module or unit of assembly, both at the micro-scale of biological structures, and the macro-scale of man-made systems. The goal of this essay is to question the relation between physically crafted component assemblies, as a means for exploring adaptive, complex, self-organizing systems, and bio-computational paradigms as a source of adaptive strategies for making.

summary In the last few years remote collaborative design has been attracting interest, and with good reason: Almost everything we use today, whether it is the structure we inhabit, the vehicle we travel in, or the computer we work on, is the result of a number of participants’ contributions to a single design. At the same time, more and more design teams are working in remote locations from one another. In a distributed design situation with remote players, communication is key for successful and effective collaboration. Archville is a distributed, Web-based VR system that allows multiple users to interact with multiple models at the same time. We use it as a platform to exercise collaborative design by requiring students to build individual buildings as part of a city, or village and must share some common formal convention with their neighbors. The Archville exercise demonstrates to students how we can use computing and the Internet to design collaboratively. It also points out the need to have correct up-to-date information when working on collaborative projects because of the dynamic nature of the design process. In addition to architectural design and computer modeling, the exercise immerses students in the political and social aspects of designing within a community, where many of the design constraints must be negotiated, and where group work is often required. The paper describes both the pedagogical and the technical attributes of the Archville project.

summary The authors introduce the concept of a Pixel Stream Editor. This forms the basis for an interactive synthesizer for designing highly realistic Computer Generated Imagery. The designer works in an interactive Very High Level programming environment which provides a very fast concept/implement/view iteration cycle. Naturalistic visual complexity is built up by composition of non-linear functions, as opposed to the more conventional texture mapping or growth model algorithms. Powerful primitives are included for creating controlled stochastic effects. The concept of 'solid texture' to the field of CGI is introduced. The authors have used this system to create very convincing representations of clouds, fire, water, stars, marble, wood, rock, soap films and crystals. The algorithms created with this paradigm are generally extremely fast, highly realistic, and asynchronously parallelizable at the pixel level

summary This study presents preliminary results of an experiment of production and use of tactile models to explain the form of an architectural space for visually impaired people. As part of a literature review, it explores the digital manufacturing technologies such as laser cutting and 3D printing to generate representations. The review uses a case study representing a house-museum and the experiments are based on a partnership with a school for a visually impaired people. The collaborative process has contributed to learning and explanation of multi-sensory characteristics of the constructed spaces and reinforced the need for a revision of educational processes for the architectural project regarding the habit of prioritizing essentially the aesthetic and visual aspects. The universal design concept gives grounds for each action.

summary Recent advances in architectural and engineering technology have opened the door for complex architectural expression in today’s built environment. When pushing the envelope on geometric complexity, architects and engineers must begin a dialogue early on in the design process and communicate effectively throughout. Using digital models for communication, visualization, and analysis creates additional digital information that may need to be shared. Middleware provides interoperability between different software packages and facilitates the exchange of information. However, this does not exempt the partners from maintaining traditional lines of open communication. This paper will discuss the importance of open communication and demonstrate a strategy for sharing digital information. The case studies that will be presented are taken from design projects whose geometric complexity required close partnership between design team members. Effective communication will first be discussed in the context of three sculptural concept designs. Second, the interoperability of digital models will be discussed through a case study of a complex, faceted super-tall high-rise tower.

summary This paper presents the results obtained through the development of furniture kits and physical model, aiming to compare the minimum design requirements described in the anthropometric ergonomics, current housing program and construction law. The qualitative approach through bibliographical and documentary revision allowed the choice of technical representation, using BIM software for design and subsequent digital prototyping. It concludes that the creation of environments according to the minimum requirements does not allow the use of space according to its purpose, and by making use of furniture kits, it is possible to obtain experiments and better understanding.

title Landscape of the Mind
source Reality and Virtual Reality [ACADIA Conference Proceedings / ISBN 1-880250-00-4] Los Angeles (California - USA) October 1991, pp. 71-86
summary The focus of this article is the exploration of landscape and the question of representation, more specifically how landscape principles can be represented through computation. It is a quest for essential qualities, through an application of philosophical questioning, and a response to a human perception of reality. Reality, as an invention of the human mind, is often thought of as a set of accepted conventions and constructs. Such a reality has an inherent dependency upon cognition where spatial and temporal principles may be defined within the natural and built environment, and further embraced within a cultural context. However, there also exist rules or relations that are neither invented nor formulated by the participants understanding. In effect these relations may not have been effectively articulated, a result perhaps of unfamiliar cues. Therefore, to the participant, these relations reside in the realm of the unknown or even the mystic. The aesthetic often resides in the realm of the mystic. The discovery of the aesthetic, is often an experience that comes from encountering physical and essential beauty where it has been produced through unconscious relations, perceived, yet transcending human understanding. The aspects of space and time, spatial and temporal properties and relations of things and events, are generally accepted conventions. Yet, the existence of a time order, is often not perceived. An understanding of spatial temporal properties may involve a temporal detachment from convention, allowing the release of previously unknown patterns and relations. Virtual realities are well constructed simulations of our environments, yet they may lack the embedded essential qualities of place. Virtual reality should transcend human perception and traditional modes of understanding, and most importantly our limited notions of the temporal nature of our environment. A desire to reach beyond the limits of perceived time order, may take us beyond existing sets of cultural values, and lead to the realization of new spatial/temporal conventions with the assistance of the computer.

summary The instrumental and aesthetic implications of architecture’s engagement with science and technology has a long history, part of which includes the period following the Second World War when the rapid technological advances of the Industrial Revolution merged with a general cultural mindset characterized by themes of progress and futurism. For postwar thinkers like Reyner Banham, this interest in a futurist architecture suggested an approach to design rooted less in architectural precedent than technological extrapolation. While a precedent based approach might be viewed as more disciplinary in nature, technological extrapolation suggests an inclination towards interdisciplinarity. Thus, Banham’s concept of extrapolation encouraged architects to look beyond the limits of their own discipline as a means of discovering new forms of knowledge and expertise. Indeed Banham was engaged in taking stock of the technological advances particular to his time while simultaneously anticipating the implication of these advancements for the future. To this extent, the postwar period and its inherent futurism provides a useful and poignant lens through which to take stock of our own technological climate. Given the equally revolutionary advances in computer technology in the last twenty years, our contemporary moment can be seen as having many parallels with the postwar period, and not unlike the postwar generation of architects and thinkers, contemporary designers are inevitably faced with the challenge of engaging new technological advances and their implications for architecture. In our current age of digital and biological technologies, these advances are both rapid and widespread, and include LED and fiber-optic lighting systems, motion sensing, interface design, solar tracking photovoltaic skins and wind harnessing technologies, magnetic levitation, and robotics. This paper begins with an examination of design work and criticism from the postwar period and proceeds to utilize that examination as an historical framework for addressing issues of contemporary design and 21st Century technological advancement.

Resources should be used as knowledge structures to organize the data involved in such systems and generalizations to reduce the data volume and create overviews. This paper discusses what is meant by resources in the context of GIS and planning and how generalizations can be used in a wider perspective than only for cartographic simplification. The project, which is in an early state, has the goal to design the data structures for a decision support system for crisis and emergency management.

summary This paper develops the topic of morphological generation of artificial landscapes using digital media. Current trends in landscape composition link architectural style to ground topography; buildings are not simply placed on the land, instead, they emerge from it, generating alternative morphology landscapes, or so-called “topographic landscapes” that emerge from the massive incorporation of computer technology in the design process, and are supported by the complex organization of topologic geometry. There has been a change from the classical method of architectural composition, in which rather than linking diverse shapes together in a static layout, dynamic actions inspired by the landscape are linked instead.

summary Part of our research and teaching agenda at the School of Architecture of the Technical University of Crete focuses on algorithmic design with parametric models, its methodological characteristics and the study of applied and theoretical work that defined this architectural design thinking. Our work challenges architectural design processes, through the systematic study of parametric models. This paper presents three projects from the undergraduate elective course "Special Topics in Architectural Design", which took place during the spring semester of 2017, that investigated parametric models for a given architectural problem, inspired, to some extent, by precedents in 20th century architecture where students traced algorithmic design thinking. Although students understood well the concept and function of parametric models and in many cases applied them successfully for their design objectives, several of them did not fully assimilate some critical aspects of computation. This allowed us to determine areas of improvement and points of complete reevaluation in our educational strategy approach.

title Algorithmic Thinking in Design and Construction - Working with parametric models
source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 19-28
summary This paper examines the parametric model in algorithmic design processes, using the outcome of an educational digital design and fabrication course as a case study. In its long history, algorithmic design as a form-finding method, allowed designers to manage complex non-standard associative geometries, suggesting a shift from the digital representation of form, to its systematic representation into a parametric model through code. Rather than a style or a tool, the parametric model is best defined in mathematical terms; in practice it incorporates the organizational logic of the form and the topological associations of its parts, so that a change in its constitutive parameters will invoke a concerted update of the entire model, and, iteratively, formal and structural variations. In a series of design experiments that took place at the School of Architecture of the Technical University of Crete in the spring of 2015, we used parametric models represented into visual code, from the initial conceptual stage to fabrication. From the experience and outcome of this course, we deduced that, compared to other digital formation methods, parametric models allow the designer to constantly interact with the model through the code, producing discreet variations without losing control of the design intentions, by “searching” into a wide range (albeit finite) of virtual results. This suggested a shift in culturally embedded patterns of modernist design thinking.

summary The main purpose of this research is to introduce and verify selected advanced computational methodologies operating with agent-oriented approach that are applicable within the framework of emergent urban design strategies in early stages of zoning proceedings. The aim is to demonstrate that speculative matter of the phenomenon of emergence in terms of design thought driven by computational models can also be applicable within real existing urban conditions. The research concurs previous researches in the field of urban pre-reconfigurations in the selected city environments. It concentrates on developing a simulation model as an analytical and generative instrumental platform for architects in early phases of urban design and synthetizes accumulated computational advancements based on agent-oriented approach.

summary Documentation errors have been identified as a significant problem within the construction and engineering industry. Errors contained with contract documents can contribute to loss of profit, reduced productivity, and cost and time overruns as well as contractual disputes. Research has identified that as much as 60% of variations in construction and engineering projects are a result of errors and omissions contained within poor quality documentation. Using a case study, errors, omissions and information redundancy contained in the Electrical and Instrumentation (E&I) 'As built' drawings for a Stacker Conveyor is examined. A total of 449 errors and omissions were identified within 42 documents. In addition, 231 cables and components appeared once among the 42 documents; 86 cables and components appeared twice and 12 cables and components appeared three times. As a result of the errors, omissions and redundancy, requests for information (RFIs) are required. Retrospective analysis indicates that the indirect cost of raising the RFIs to the contractor was estimated to be 8.93% of the cost of the E&I contract. To address the problems of errors, omissions and redundancy, it is suggested that there is a need to adopt an object orientated system information model (SIM) for E&I engineering design and documentation. It is demonstrated in the case study that the use of a SIM could bring significant improvements in productivity and reduce the cost of engineering design.

summary This paper describes some visual phenomena of human perception in the context of computer based Illustration. Some of these phenomena of the human visual system will be used to introduce an illustrative rendering style for three-dimensional line drawings with enhanced depth cuing to visualize spatial properties of three-dimensional objects. The additional purpose of this paper is to inspire the study of human perception more deeply to derive new non-photorealistic rendering methods that can enhance the visualization of complex spatial concepts and its three-dimensional characteristics.

summary My contribution deals with light and colour effects in wider dimensions of architecture. It analyses their significance in urban environment perception from the application aspect of progressive tools of its forming and creative completion, i.e. the perceptual homomorphous iconic simulations in laboratory conditions. The work focuses on questions of light and colour perception, showing several principles and phenomena valid in visual perception systems. The structure of the perceived picture is interpreted in its four components: colour, motion, form and spaciousness. Each of the components is shown with relevant biological reactions and their reflections in subjective perception processes. The selected image examples document some manifestations of urbanistic structures and spaces experience transformation in natural and artificial lighting conditions. The emphasis of my contribution lies on some demonstrations from the laboratory experiment in investigating the illumination and colour influence on the architectural design quality, and on examples of alternative methods of visual interpretation on endoscopic modelling simulation outputs. The conclusion of my work formulates some knowledge and statement of objective colour and light modelling simulation assets in architectural design quality.

summary This paper outlines the processes involved in the design of the Smithsonian Institution’s Patent Office Building’s new courtyard enclosure. In 2004, Foster + Partners won an invited international competition to design the new courtyard enclosure in Washington, D.C. Early in the project, the Specialist Modelling Group (SMG), an internal research and design consultancy, was brought in to advise the project team on computer modelling techniques, develop new digital design tools, and help solve the complex geometric issues involved. Throughout the project, computer programming was used as one of the primary tools to explore design options. The design constraints were encoded within a system of associated geometries. This set-out geometry performed as a mechanism to control the parameters of a generative script. The design evolution involved the use of many different media and techniques and there was an intense dialog between a large team and many consultants. The computer script was a synthesis of the design ideas and was constantly modified and adapted during the design process. The close collaboration between architects, consultants, and fabricators was of key importance to the success of the project. This project, now named The Robert and Arlene Kogod Courtyard, will complete in late 2007.

summary The Spatial Sonic Network is a proposal for a series of parabolic acoustic mirrors that collect, focus, and translate sound. Computational tools were used extensively throughout the project, to realize algorithmic logic, to integrate acoustic performance into the architectural design process, and to link design models to fabrication machinery. While conceptually straightforward, the design of acoustic mirrors, also known as sound mirrors, raised several challenges in terms of network design, geometry definition, acoustic performance simulation, prototyping, and measuring. The research and results that emerged from these challenges is the focus of this paper.

summary This paper outlines the digital design processes involved in the design and construction of the new Elephant House at Copenhagen Zoo. Early design concepts for the canopy were tested using physical sketch models. The geometric complexity of these early physical models led to the involvement of the Specialist Modelling Group and the use of the computer to digitally sketch 3D CAD models. After many studies, the complex form of the canopies was rationalised using torus geometry. A computer program was written to generate the canopy glazing and structure. This parametric system was developed to be a design tool, and was developed by an architectural designer working with the team. Through its use the team were able to explore more design options, and alter the design farther along in the design process; however, this generative tool was created largely as a CAD efficiency tool. Another series of computer programs were written to generate and populate a shading system based on environmental analysis. Unlike the computer program that generated the structure and glazing, this program was not developed to make the generation of complex geometric structures more efficient, but developed to explore computational approaches that would have been impossible without the computer. Most of the canopy’s design was communicated to fabricator through a geometry method statement, a method that has been proven to be effective in the past. The project completed in June 2008.

summary Acoustics are important performance criteria for architecture; however, architects rarely consider them, except, perhaps, when designing concert halls. Architectural spaces can be said to perform well or poorly in terms of their acoustic qualities. By altering the geometry or material characteristics of the surfaces within a room in specific ways, the acoustics can be controlled. Once the geometric rules governing these acoustic alterations are understood, these rules can be encoded into a CAD system through parametric modeling or the use of computer programming. The architectural designer can then generate acoustically regulating surfaces according to desired performance criteria. In this way, acoustic engineering links to architectural design, and allows architectural design to become acoustically performance-driven. This paper considers three primary types of acoustic surfaces: absorbers, resonators, and diffusers. complex surfaces that combine these three performance characteristics in different ways are proposed.

title Acoustic Performance as a Design Driver: Sound Simulation and Parametric Modeling using SmartGeometry
source International Journal of Architectural Computing vol. 8 - no. 3, pp. 337-358
summary Acoustic performance is an inevitable part of architectural design. Our sonic experience is modified by the geometry and material choices of the designer. Acoustic performance must be understood both on the level of material performance and also at the level of the entire composition. With new parametric and scripting tools performance driven design is possible. Parametric design and scripting tools can be used to explore not only singular objectives, but gradient conditions. Acoustic performance is often thought of in terms of singular performance criteria. This research suggested acoustic design can be understood in terms of gradients and multiple performance parameters. Simulation and modeling techniques for computational acoustic prediction now allow architects to more fully engage with the phenomenon of sound and digital models can be studied to produce data, visualizations, animations, and auralizations of acoustic performance. SmartGeometry has promoted design methods and educational potentials of a performance-driven approach to architectural design through parametric modeling and scripting. The SmartGeometry workshops have provided links between engineering and architecture, analysis and design; they have provided parametric and scripting tools that can provide both a common platform, links between platforms, but importantly an intellectual platform where these ideas can mix. These workshops and conferences have inspired two projects that both used acoustic performance as a design driver. The Smithsonian Institution Courtyard Enclosure and the Manufacturing Parametric Acoustic Surfaces (MPAS) installation at SmartGeometry 2010 are presented as examples of projects that used sound simulation parametric modeling to create acoustically performance driven architecture.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.481-491
summary Digital tools present the opportunity for incorporating performance analysis into the architectural design process. Acoustic performance is an important criterion for architectural design. There is much known about sound absorption but little about sound scattering, even though scattering is recognized to be one of the most important factors in predicting the acoustic performance of architectural spaces. This paper proposes a workflow for the design of complex architectural surfaces and the prediction of their sound scattering properties. This workflow includes the development of computational design tools, geometry generation, fabrication of test surfaces, measurement of acoustic performance, the incorporation of this data into the generative tool. The Hexagon Wall is included and discussed as an illustrative design study.

summary Acoustic performance is defined by the parameter of reverberation time; however, this does not capture the acoustic experience in some types of open plan spaces. As many working and learning activities now take place in open plan spaces, it is important to be able to understand and design for the acoustic conditions of these spaces. This paper describes an experimental research project that studied the design processes necessary to design for sound. A responsive acoustic surface was designed, fabricated and tested. This acoustic surface was designed to create specific sonic effects. The design was simulated using custom integrated acoustic software and also using Odeon acoustic analysis software. The research demonstrates a method for designing space- and sound-defining surfaces, defines the concept of acoustic subspace, and suggests some new parameters for defining acoustic subspaces.

summary Over the last 15 years, rapid prototyping has been an integral part of the design process in the car and aerospace industry (Brad Fox 2006). Recently the architecture profession has started to use these techniques in its design process (Greg Corke 2006), and some architecture schools have begun experimenting with these technologies. ¶ Foster + Partners have been one of the first architecture practices to fully integrate rapid prototyping within its design process. The technology was initially seen as a sketch model making tool in the early stages of the design, in particular for projects with complicated geometries. It surpassed this purpose within a year and it is now seen an essential design tool for many projects and in for many project stages. The office’s rapid prototyping department now produces about 3500 models a year. ¶ Besides, or perhaps because of, rapid prototyping, Foster + Partners have started to experiment with rapid manufacturing. This first was done through the design and manufacture of a Christmas tree for the charity organisation Save the Children.

title Simulation by Design: A Parametric Design Tool for Zero Energy Buildings
source Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary To address the shortcomings of integrating building simulation in architectural design and to make it more appealing to students, a simple interface to Energyplus was created. This interface models a simple rectangular building that is passively heated by direct gain and cooled by ventilation. A simple photovoltaic interface has also been added to supply fan energy. This tool has an OpenGL modeler for visualization and uses Energyplus for calculations. The interface will run a full year simulation and graph the results. The results are reported in a yearly graph that shows the outdoor and indoor temperature. The indoor temperature range is based on adaptive comfort level. The interface was tested and used in an introductory design studio in order to comply with the 2010 imperative. The students simulated a simple box and changed the buildings parameters until the building fell within the adaptive comfort zone for most of the year. The climate simulated was Chicago, IL. Using these parameters the students then designed the building. The resulting designs show that even though the students were restricted in parameters, such as window percentage, they were still able to creatively design unique buildings that use zero to negative net energy for heating and cooling in a climate such as Chicago.

summary This paper celebrates the successful outcome of a trial of an innovative multi-platform distributed design decision support system in which the shared design environment exists within the virtual world. The outcome is the result of a sustained three-year research and development effort, within an internationally recognised research group. The project set itself a number of ambitious targets within the broad spectrum of distributed design decision support, viz: • A multi-platform environment: the trial demonstrates inter-operability of different machine platforms - from a home PC to an international standard Virtual Reality Centre. • A distributed environment: the trial demonstrates the high level of understanding amongst the design team separated by time and space. • An ability to propose, discuss and agree upon, design decision from within the virtual world. Hitherto, virtual environments were viewing galleries; designers had to leave them to effect design changes in a conventional CAD package. The trial described in the paper amply demonstrates the potential to design, collaboratively and, in distributed mode, from within the virtual world. The two ideas upon which the system (known as JCAD-VR) is built are: • That all the users present in the virtual world have to be able to share the same virtual environment in a "transparent fashion"; • The user interface, instead of the traditional menu/windows based layout, is part of the virtual world itself. Any element of the interface becomes an object belonging to the 3D world and therefore it is treated as any other object. Each element of the interface can then be moved or scaled according to the user’s needs. The entire project is based on client-server architecture where every user logs into a virtual world and starts sharing design tasks with other users. The authors propose to present a video which demonstrates the positive outcome of the trials to date. More importantly, perhaps, the authors will put the achievements of the R+D into the context of past aspirations and developments in the subject area and, most importantly of all, suggest how these modest achievements will impact on the next decade of increasingly rapid R+D.

title Virtual Reality in the Service of User Participation
source Distributing Knowledge in Building. Proceedings of CIB W78 Conference (Ed. K Agger et al), Aarhus, 217-224
summary The normal application of Virtual Reality is to the simulation of environments which are in some way special - remote, hazardous or purely imaginary. This paper describes research and development work which changes the paradigm by simulating perfectly ordinary buildings for special people. Some of the population have some form of physical impairment - a proportion which is likely to rise in line with an ageing population. New legislation, such as the UK Disability Discrimination Act places additional responsibility on building owners to ensure adequate access for people with an impairment and this in turn will place additional responsibility on the architect. Current methods of auditing access for new building are primitive and require the auditor to interpret plans/sections of the proposed building against a checklist of requirements specific to the special need. This paper reports on progress in the use of an immersive VR facility to simulate access to buildings for two broad classes of user:

i) those with a mobility impairment

ii) those with a visual impairment

In the former case, a wheelchair motion platform has been designed which allows the wheelchair user to navigate the virtual building; a brake and motor connected to the rollers on which the wheelchair sits facilitate the effects of slope and surface resistance.

summary This paper elaborates and illustrates an educational experiment in which students were asked to develop their design in the virtual environment and at the same time evaluate the process and the product. Starting from a general overview on the VRML 97 technology the workshop offered an opportunity to students to enhance their curricula with new tools through experimenting and interacting with their design spaces. Students’ designs were tested and critically discussed in a fully immersive VR environment offering them new stimuli for both designing and enriching their learning experience. Students were finally asked to present their projects in a fully interactive VR environment. The outcomes of the experiment, and the challenging question it raises about the nature of reality and virtuality – technical, pedagogical and even ethical – offer a contribution to the debate on the concept of an “Ideal Digital Design Curriculum”.

source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 159-162
summary This paper re-establishes the theoretical framework for participatory design evolved in the late sixties and early seventies as part of the movement towards a more explicit design methodology and attempts an explanation of why the concept failed to gain commitment from the architectural and urban design professionals. The issue of user participation in the processes of building and urban design is enjoying renewed attention following its relative neglect over the last 20 years due, in large measure, to significant advances in emerging information technologies, particularly multimedia, virtual reality and internettechnologies. This paper then gives an account of two significant and relevant developments in the evolution of the application of informationtechnologies with which the authors have been engaged. These are:a responsive and interactive interface to wholly immersive and realistic virtual reality representations of proposed buildings and urban neighbourhoods. an intuitive and platform-independent VR modelling environment allowing collaborative evolution of the scheme from withinthe virtual world. The efficacy of these IT developments is tested in the context of a design exercise in which three designers, from distributedlocations and using different computer platforms, collaboratively design an Information Centre from within the virtual world.

summary This paper addresses an articulated vision of Virtual Reality which lends itself to design collaboration in teaching, learning and communication of architectural design ideas among students, design professionals and client body during the early stages of the design process. Virtual Reality (VR) has already acquired a new degree of complexity through development of network-based virtual communities and the use of avatars. The intrinsic quality of VR technology is to support collaborative design experience. The design tools developed for this experiment are capable of creating 3D objects in a shared VR environment, thus allowing the design and its evolution to be shared. The choice of programming language (JavaTM) reflects the desire to achieve scalability and hardware independence, which in turn allows for creation of a VR environment that can co-exist between high-end supercomputers and standard PCs. The prototype design environment was tested using PC workstations and an SGI system running a Reality Centre. The research and teaching/learning experience in the collaborative design environment reported in this paper describe the development and application of software that aims to increase the opportunity for architects to collaborate within virtual worlds which enable effective and transparent information exchange.

summary This paper suggests that the theoretic framework devised in the late 1960s to help structure the IT curriculum in Schools of Architecture has served the community of teachers and students well but must be re-visited to take proper account of the recent and rapid developments in Virtual Reality and Real Virtuality. The paper offers definitions which differentiate these terms and suggests that the emerging technologies will have a major impact on the issues of sustainability, user participation and creativity. It ends with an appeal for the discussion of the theoretical and philosophical ideas raised by virtuality, and the development of the skills to test them, to be put at the heart of the architectural agenda and curriculum.

summary The paper starts with a re-iteration of the concept of appraisal of digital prototypes during the early phases of the architectural design activity and with a summary of research and development from the early seventies to the current time; the use of appraisal by progressive practices is described in the context of the company Integrated Environmental Systems. The paper then focuses as an experiment which set out to determine how the information delivered by the computer based appraisal of virtual prototypes is ordered and used by professionals in the evaluation of design alternatives. The information provided to the professionals is detailed and their self-assessment of their management and utilsation of the data is reported, together with their critique of the experience. Conclusions are drawn and future research directions proposed.

summary In this current era it is the information technologies that has set the stage for the drama of human life to be acted out. The information revolution has created global links on a scale unparalleled in human history. With exciting explorations into virtuality (the current buzz word) our life experiences, dreams and ambitions will be mapped into cyber-space and our "real" reality will become indistinguishable from our virtual reality. We are on the verge of experiencing a complete sensory immersion in this man-made cyber-dream. We will be able to enter virtual space that has as much richness and tangible quality as the world from which it sprang.

title Real Teaching and Learning through Virtual Reality
source International Journal of Architectural Computing vol. 1 - no. 1
summary This paper addresses an articulated vision of Virtual Reality, which lends itself to design collaboration in teaching, learning and communication of architectural design ideas among students, design professionals and client bodies during the early stages of the design process. Virtual Reality (VR) has already acquired a new degree of complexity through development of network-based virtual communities and the use of avatars. A key intrinsic quality of VR technology is to support collaborative design experience. The design tools developed for this experiment are capable of creating 3D objects in a shared VR environment, thus allowing the design and its evolution to be shared.The choice of programming language (JavaTM) reflects the desire to achieve scalability and hardware independence, which in turn allows for the creation of a VR environment that can co-exist between high-end supercomputers and standard PCs. The prototype design environment was tested using PC workstations and an SGI system running in a Reality Centre.

summary The paper describes a recent project whose objective was to redesign GIMSEX-PERT, an existing architectural knowledge- based design system developed in 1987. Its critical generative problems appeared to be the rigid structure and limited evaluation criteria. The project's outcome is DESTOOLS, based on the 'object-oriented-methodology' inspired by the traditional trial-and-error approach. It includes a set of interchangeable design methods that can be applied interactively by any desired sequence, producing or transforming a GIMS Building System object. Such 'moderately- loose' system structure offers flexibility in use, avoids pitfalls of knowledge-based design systems with rigid structure, and is applicable in design research, education and practice

Starting with simple algorithmic drafting programmes, the work transcended to expert systems and distributed artificial intelligence, using computers as tools. The research cycle is about to begin afresh; computers in the next century shall not be detached entities but the extensions of man. The computer shall be the medium that will enable a designer to be what he/she really is. This future has already begun.

summary A design studio of the future shall be based on dislocated, distributed design services, and feature the ‘design by collaboration’ enabled by the computer transmitted information. However, in a collaborative design process, computer may take an additional role, i.e., as an “ultimately structured dynamic communication medium ... based on the notion of commitment and interpretation” (Winograd and Flores 1987). Various models of ‘intelligent’ design systems based on the ideas of ‘open, distributed, artificial intelligence systems’ have shown that the computer-based design agents which act on the object-to-be-designed model could be involved in a “conversation for action” (Winograd and Flores, Ibid.). The aim of the paper is to illustrate a computer-based design system that enables ‘a-kind-of’ conversations by the design agents before the design decisions were made. After the description of a design experiment and the conversation that went on between the design agents, the traits of the applied ‘design design system’ are discussed.

A process leading to definition of the expected performances of design agents is desribed, and some possible applications illustrated. The framework includes not only the objective, but also, the "subjective" agents. It is expected that the framework would offer an insight into the intricacies of CAAD in an educational environment, and provide the exploration paths and an efficient production of alternative solutions in an office.

The computers were significantly involved in both, making the offer, and organisation of project design phase. The story illustrates some interesting relationships between IT and certain types of design problems. The paper presents how the offer was prepared, discuss whether the computers would be beneficial in getting the design tasks done, and finally, pose the question whether such design tasks could be achieved without the help of computers. The explicit design tasks and use of the computer tools make this case of "computerised craftsmenhip" appropriate for presentation in educational environments.

summary The paper explores the use of in-house developed self-reconfigurable modular robotic system in civil construction activities and investigates a concept where an arbitrary Civil Engineering structure or a daily use industrial product are self-assembled from a number of self-reconfigurable composite blocks. The system extends current range of modular robot systems (mDrs) where autonomous modules self-assemble into a wide variety of forms. However, contrary to conventional mDrs, MoleMOD has not mechatronic actuating parts permanently fixed to each individual module. The MoleMOD actuators are separable and operate inside the modules, tight them together or relocate them to required configuration. It significantly reduces number of expensive mechatronics parts and the environment the actuators operate. Although MoleMOD focuses on architecture, it can take over other mDrs tasks as research and rescue. This paper describes properties, advantages, foreseen applications, and basic design specifications of the second generation prototype.

summary Activities in the building industry in Europe concentrate increasingly on a combination of renovation and new-building. A prerequisite for comprehensive IT supported design and planning in the context of existing buildings is both the use of on-site computer- aided surveying techniques and the integration of all professional disciplines in an integrated information and communication system. The starting point is often the building survey on site. An examination of currently available IT tools and hardware shows insufficient support for planning within existing built contexts. Surveying equipment has been derived from other disciplines without being modified to cater for the specific needs of building surveying. This paper describes a concept for computer-aided digital building surveying equipment based upon a wearable computer and AR to close the gap between specialist equipment adapted for use in building surveying and the need for simple straightforward surveying equipment for architects and engineers.

source Abstract Book CIPA 2001 International Symposium, Potsdam 2001, pp. 58
summary Future tasks for the building trade in Germany will be more and more a combination of the fields of revitalization and new building projects. Prerequisite for computer-aided planing for existing buildings is both, the use of onsite computer-aided measurement and the integration of all specialists involved in the building process. Existing approaches for this problem are not yet satisfying. The aim of this research project is twofold: to design a practice-relevant software concept and to develop various prototypic systems, for a structured way of capturing and organizing building-related information about existing buildings in digital form. The research is oriented towards existing buildings, in particular residential and commercial buildings. This project is a special branch of SFB524. The project is founded by "Deutsche Forschungsgesellschaft (DFG)".

summary Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A prerequisite for computer-aided planning in the context of existing buildings is both the use of on-site computer aided surveying techniques and the integration of all professional disciplines in an integrated information and communication system. Current approaches to these issues are unsatisfactory. Methods and techniques in renovation work are being investigated as part of ongoing research at the Bauhaus- Universität Weimar (SFB524 - “Collaborative research center 524 „Materials and Structure in Revitalization of Buildings”). A sub-group (SFB524 - D2 „Planning-Relevant Digital Building Surveying and Information System”) is currently investigating the possibilities of computer-aided building surveying and of joint communcation platforms for engineering disciplines (www.uni-weimar.de/sfb: May 2001). The objective is the development of a general approach for the renovation of buildings. The paper discusses concepts and requirements for a computer-aided system supporting the entire surveying process from the initial site visit to its use in a CAD system.

title Digital Building Surveying and Planning in Existing Building

summary For planning in existing built contexts, the building survey is the starting point for initial planning proposals, for the diagnosis and documentation of building damages, for the creation of objectives catalogues, for the detailed design of renovation and conversion measures and for ensuring fulfilment of building legislation, particularly by change of use and refitting. An examination of currently available IT-tools shows insufficient support for planning within existing contexts, most notably a deficit with regard to information capture and administration. In ongoing research at the Bauhaus-Universität Weimar (SFB524- Collaborative research center 524 “Materials and Structure in Revitalization of Buildings”) methods and techniques of revitalisation are being investigated (SFB 524, 2004). A special branch of SFB524- D2 entitled “Planning-Relevant Digital Building Surveying and Information Systems” is investigating possibilities of computer-aided building survey and communication platforms for architects and civil engineers. This paper discusses the concept for a modular surveying system (basic concept, structuring of collected data, separation of geometry from semantic data, and separation into sub-systems) and the prototypical realisation of a system for the complete support of the entire building surveying process for existing buildings. The project aims to contribute to the development of a planning system for existing buildings.

summary CA(A)D systems are nowadays a part of everyday architectural practice and have completely replaced drawing with pen and T-square. The standard functions of such systems are (usually) sufficient for the everyday needs of practical work. The question is: can CA(A)D systems be adapted to improve work efficiency for specific users or applications such as those of the architect? Most current CA(A)D systems already provide some level of support for individual adaptation however these are rarely exploited by the end users. This paper discusses the teaching of skills for adapting and extending existing CA(A)D systems in current architectural education. In addition to the teaching of programming and operational skills, the course also examines the critical examination of CA(A)D systems and the formulation of user requirements (analysis), the search for existing solutions, functions or extensions (research) and the technical adaptation or extension of the system (software development). Using examples from current coursework, the paper illustrates both process and results of teaching practice.

source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary The application of new media is common practice in architectural offices and complements traditional forms of presentation such as drawings and physical ‘haptic’ models. Other interactive forms of presentation are also already available, for example in the realm of computer gaming, however the transfer and application of game engines to an architectural environment has not yet been explored in any depth. This paper looks at how “new media” can be used as a means of communicating architectonic information without simply emulating an already available traditional means of representation. We discuss the process of learning how “new media” (the computer as a multi media) can be used as a tool for the analysis and reconstruction of architecture. Using Mies van der Rohe’s unrealised project for a brick country house as a basis, a project was devised which communicates valuable design and analysis skills and also allowed us to explore the use of “new media” and to draw conclusions for teaching and research as well as to critically assess the opportunities, limitations and risks involved.

summary Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A look at current computer aided applications reveals a serious lack of IT support for the whole architectural design process in and within existing buildings (e.g. building surveying, designing on site and the preparation of information for further use in later planning stages). An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process in and within existing buildings. The goal is to develop a hardware and software concept for a “design-toolbox” based on SAR (spatial augmented reality) and to implement aspects of this as prototypes. This paper describes the goals of the “Spatial Augmented Reality for Architecture” project and discusses possible fields of application for SAR for supporting the design process in existing buildings from a user’s perspective. This paper presents the initial results of the project, the development of a cave-like hardware and software concept called “low-cost projection in room corners” and the description of the core concept based on a client-server architecture. The project is funded by the “German Research Foundation (DFG)”.

title High-precision application of GPS in the field of real-time equipment positioning
source Automation in Construction 9 (3) (2000) pp. 299-314
summary In the frame of its research concerning real-time positioning and control of road construction equipment, the Laboratoire Central des Ponts et Chaussées, has carried out in 1996 a study to know more about the actual vertical accuracy that a real-time kinematic (RTK) global positioning system (GPS) sensor could reach, under work site conditions. This study has widely used the dedicated testing facility called SESSYL, built to perform high-accuracy and real-time evaluation tests on positioning systems. It has been performed in collaboration with the French road contractor COLAS and the Ecole Supérieure des Géomètres et Topographes (ESGT). First, there is the proposed adapted geodetic transformation procedure, compatible with the high accuracy requirements. Then, the main results of a special SESSYL tests program are presented, where the impacts of several influencing parameters on the vertical accuracy have been carefully examined. The core part of the paper is the analysis of the typical RTK GPS set of data, from which we have tried to extract two different components: a high-frequency noise, rather easy to filter, and a low-frequency bias. This bias, given its good repeatability, can be modelled and used in prediction to improve in real-time the raw accuracy of the data. As a full-scale validation of our study, a site experiment is finally described, carried out this time on a real piece of equipment (an asphalt paver) during real roadwork.

title The Computer Integrated Road Construction project
source Automation in Construction 9 (5-6) (2000) pp. 447-461
summary This paper is about the "Computer Integrated Road Construction" (CIRC) project, which is a Brite-EuRam III funded project, lasting 1997–1999, aiming at introducing a new generation of control and monitoring tools for road pavements construction. These new tools are designed to bring on the sites significant improvements by creating a digital link between design office and job site. The first part of the paper describes the background of the project, which gathers seven European partners from five different countries, and gives the objectives of the project, in general and for each of the two targeted products: one for the compactors (CIRCOM) and one for the asphalt pavers (CIRPAV). Then, the two prototypes are described, each of them being broken down into three main sub-systems: the ground sub-system (GSS), the on-board sub-system (OB) and the positioning sub-system (POS). The expected benefits for the different users are also presented and quantified. The central part of the paper is devoted to the main technical innovations that have been developed in the frame of the project: universal vector database for road equipment guidance, multi-machine functionalities of CIRCOM and the two positioning systems which are actually the technological keys of the systems. Finally, the state of progress of the developments of the two CIRC products and the first commercial success achieved in parallel are presented.

title A new facility for testing accurate positioning systems for road construction robotics
source Automation in Construction 8 (2) (1998) pp. 209-221
summary The first part of the paper gives a definition of positioning in the context of road work sites and stresses the advantages offered by the new generation of positioning systems. A logical classification of these systems is also proposed. The `global positioning system' (GPS) technique, as one of the most promising techniques, is detailed. The main point of the paper is the presentation of a new test facility for positioning systems which has been set up at the `Laboratoire Central des Ponts et Chaussées' (Central Laboratory of Roads and Bridges). First, its principle is described, based on the re-construction of a 6D reference trajectory to which the measurements of the system in test are compared. Then, the operation of the facility and the post-treatment software which has been specially developed for it are described. Finally, the results of some recent studies are given, results which would have been hard to obtain without using the SESSYL facility. During the first study, the facility was used to establish an accurate time-model of the vertical error and this model allowed us to propose an innovative method for improving the vertical accuracy. During the second study, SESSYL proved its capability of differentiating several state-of-the-art GPS receivers of the same category.

summary This paper is an account of the façade rationalisation strategy developed at Gehry Technologies for mitigating the tradeoffs between project constructability and the aesthetic implications of arranging flat panels over a complex surface. The strategy outlined was developed as the result of the digital building delivery of the Museo Soumaya façade in Mexico City designed by Fernando Romero LAR. This report documents the development process of a method for obtaining relevant construction information flows enabling the assembly of the façade system by a third-party sub-contractor in support of the façade system coordination. This report concludes on a method using bespoke software for extending the parametric modelling system Digital Project™ in the design support role of obtaining an aesthetically pleasing arrangement of flat hexagonal panels over a freeform surface.

title Are European cities becoming similar?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The paper discusses city specific development patterns to overcome todays transport problems. The results are based on recent andongoing research activities at TUW-IVV and ITS. At previous CORP-conferences, we presented the basics and the development of aplanning support tool to find optimal policy packages in urban transport and land use (Emberger, 1998), (Pfaffenbichler, Emberger, 2001). The core of this planning support tool is a dynamic land use and transport interaction model. This model, which we refer to as Sketch Planning Model (SPM), is embedded into an appraisal and optimisation framework. The SPM and this framework were developed in the recently finished European Union funded research project PROSPECTS1. Case studies with this planning supporttool were performed within PROSPECTS for the cities Edinburgh, Helsinki, Madrid, Oslo, Stockholm and Vienna. These cities are principally comparable in regards of their status (capitals and major business and education centres), but different in their size, population density, transport system etc. A set of policy instruments like public transport improvements, car traffic restrictions, and infrastructure provision was available to formulate strategies to reduce negative impacts of transport and to increase welfare. The overall objective was a sustainable development of the city. Although the instruments and the goals are similar in all investigatedcites, different solutions were adequate. The solutions vary in regard of spatial implementation, implementation time and level of implementation. The paper will highlight some reasons for the different development paths of the cities. As well the comparison of the do nothing scenario as the comparison of the most feasible policy strategies shows that European cities are different, need different solutions for their problems and will stay different in the future.

summary Concepts and ideas take shape in the head. Human beings think by relying on visual forms, they connect ideas and thoughts with images. Especially when we are dealing with complex processes, visualizations have always helped to increase our understanding of contents, to facilitate communication and thus to support cooperation. Communication and planning are not possible without real or imagined pictures or, as we prefer to say, images.This easily explains why computer-aided visualizations today are among the standard instruments in the field of construction and planning.

summary People are aware of objects in physical spaces to which they may act responsively. We are interested in human behavioral changes in the presence of reactive displays in shared environments. In a limited 2-week field study, using plants (both natural and artificial) as reactive displays, we observed human trash disposal/recycling behavior. We found that there is a significant increase in recycling (p=0.08) when there are reactive display with natural plants. We also noticed increase in recycling with displays with artificial plants. These findings suggest that people can and do alter their behavior in shared environments, and that such behavioral changes can be effected by the use of reactive/responsive information displays.

title Augmented Reality-Based Education and Fire Protection for Traditional Korean Buildings
source International Journal of Architectural Computing vol. 8 - no. 1, 75-91
summary This study examines an application of Augmented Reality technology (AR) for Korean Cultural Traditional Buildings, specifically, the Namdaemun Gate, "National Treasure No 1" of the Republic of Korea. Unfortunately, in February 2008, the Namdaemun Gate burned down, despite the efforts of many firemen, as the main difficulty was getting the fire under control without any structural knowledge of the wooden building. Hence, with the great advances in digital technology, an application of virtual technical information to traditional buildings is needed, and the new technology of AR offers many such advantages for digital architectural design and construction fields. While AR is already being considered as new design approach for architecture, outdoor AR is another practical application that can take advantage of new wearable computer equipment (Head-mounted display also know as HMD, position and orientation sensors, and mobile computing) to superimpose virtual graphics of traditional buildings (in this case, Namdaemun Gate) in a real outdoor scene. Plus, outdoor AR also allows the user to move freely around and inside a 3D virtual construction, thereby offering important training opportunities, for example, specific structural information in the case of firemen and mission planning in the case of a real-life emergency. In this example, the proposed outdoor AR system is expected to provide important educational information on traditional wooden building for architects, archaeologists, and engineers, while also assisting firemen to protect such special buildings.

summary Collective Design seeks to explore how new forms of Collective Intelligence, arising from the web, allows mass participation in design. Regarding design we have a wellestablished grounding for understanding how design works through the use of representations. Likewise, collective intelligence via certain crowdsourcing examples has demonstrated that a diverse crowd can trump ability groups, when the conditions are right. In the literature, crowdsourcing is the leading lens bridging design with collective intelligence. However in crowdsourcing design there is less focus on the role of shared representations, subsequently any collective diversity is mitigated by the models that govern the extraction of this intelligence. We propose that more effective design in collective intelligence lies in the crowd’s ability to generate meaningful contributions via the content of shared representations. In order to investigate this, the current paper examines data collected from a pilot study in which a representationally rich online collaborative presentation tool is used to provide a shared design space. The analysis presented applies our previously established semiotic framework to identify potential patterns in the meaningful communication of image based design information.

title Kinetic Hybrid Structure Development and Simulation
source International Journal of Architectural Computing vol. 10 - no. 1, 67-86
summary Supported through technological advances, the concept of kinetic architecture is internationally increasingly acknowledged in the past years in the development of adaptable buildings as to differing functional requirements, or external loading conditions. Most decisive factor is the structure in terms of materials and geometrical configurations, and the control system integrated within. Based on general principles of tensegrity structures, a hybrid system has been developed that consists of continuous hinge connected compression members, strengthened by an internal system of struts and continuous cable diagonals with closed loop. The kinetic mechanism is achieved through alteration of the cables length and the respective relative inclination of any adjacent compression members. In this way the transformability of the system arises primarily from the inherent integrative composition and dual capabilities of its members. Following the construction design of the prototype structure, the interactive development, as regards geometric properties and structural configurations, is presented analytically, as based on a parametric-associative design approach applied. Along this line, the specific syntax of structural development and simulation through parametric design is suggested to support in real terms the control design of the innovative structure in an integrated interactive context.

summary The quality of computer generated images of three-dimensional scenes depends on the shading technique used to paint the objects on the cathode-ray tube screen. The shading algorithm itself depends in part on the method for modeling the object, which also determines the hidden surface algorithm. The various methods of object modeling, shading, and hidden surface removal are thus strongly interconnected. Several shading techniques corresponding to different methods of object modeling and the related hidden surface algorithms are presented here. Human visual perception and the fundamental laws of optics are considered in the development of a shading rule that provides better quality and increased realism in generated images

summary Generative design system develops the purpose that is can generate a large number of design plans. Generative design system can let designer unceasingly explore the new design plans. At present generative design system, they all only have one kind of generative mechanism. Therefore, one can’t provide enough feasibility for designer to explore new plans. So, in this paper, we propose a Co-Generative Form System (COgenForm). COgenForm is a 3D form exploration system that invokes two set of generative mechanisms. This system used co-evolutional characteristics to build the steps and framework of co-generative design process. This system includes two groups of generative mechanisms and these will evolve with each other. Using this system, the form exploration and generation process can be more dynamic and more alternatives.

It is based on previous studies on architecture, art and technology on modernity and its development, as well as studies about scale in architectural design. In despite of the fact that scale can be technically considered indifferent for computer aided design, I wish to discuss how digital tools intercede in the process of clipping that selecting a specific scale eventually implies, sustaining that for architectural design, the concept of scale has to do both with representation and knowledge of reality.

The program enables students to compose structures and to experiment interactively the effects of different geometry and load configurations. It tries to identify the proposed structure and controls its stability. Upon request of the student, it also processes displacements, internal forces (moments, shear forces, etc.) and reaction forces on supports. The students can then visualise the desired information by interacting directly with the structure or its members of interest. We present different methods with which students can visualise the results of their actions and discuss their implications in the educational context.

summary This paper aims to connect a reading of Francisco Goya’s painting Vuelo de Brujo with Marco Frascari’s metaphorical exploration of the idea of ‘monstrosity’ in architecture in Monsters of Architecture (1991). It also seeks to connect these works to contemporary forms of digital monstrosity and the proposition that the existential anxiety explored within current digital representations of the monstrous have both their basis in the technical apparatus within which they are created, and current thinking on material realism in ontology. Given the emergence of complex forms of ‘life’ within Cellular Automata studies and the speculations regarding digital ontology stemming from Stephen Wolfram’s New Kind of Science, the paper also asks what the consequences of large-scale expansions of these capabilities will entail in a post-Singularity scenario.

summary This paper investigates the relationships between conventional modes of architectural design, those represented through and mediated by Cartesian schema, and the radical organization of spatial experience available through the use of NURBS modelling. This is examined particularly through a study of how game engine software and the appropriate editors are able to accommodate the properties of both. Within this software the first-person view attempts to provide a normalised experience of the VR environment (usually a game), yet there is significant scope for experiencing radically ‘other’ spatial and topological presences. Whilst considerable work has been done in the use of participatory digital spaces, there is the opportunity for examining the manner in which a highly stylised medium such as Unreal Tournament can productively assist the architectural design process.

summary A method is developed for the efficient representation of spherical caps by using the rational Bezier scheme of Computer Aided Design. The technique is applied to describe special spherical patches such as the hemi-sphere, an octant of a sphere and the whole sphere. A geometric interpretation of quadratic curves and quadric patches is used in order to obtain an insight into the geometry inherent in the rational Bezier scheme and so to make easier the selection of the spherical patch out of the quadric primitives

summary An algorithm for approximate skinning through cross-sectionalNURBS curves is presented. The method eliminates the problem of dealing with huge amounts of control points obtained during the curvecompatability process. It also allows the designer to specify large numbers of cross-sections and approximately fit a smooth surface to these curves to any given tolerance. Depending on the tolerances used, up to99% of the control points can be eliminated.

summary The paper concerns the issue of constructing flat vaults from elements topologically interlocking inspired by the Abeille blocks. One of the new ideas that are presented is constructing the vaults in an order opposite to the one considered untill now. The problem of static response on the thrust force, significant for flat vaults, is usually solved by the use of the perimeter frame, added only after arranging all the elements of the vault. The paper presents how to arrange the vault inside a previously made frame thanks to application of special components divided into parts, which are inserted at the end and play the same role as a keystone in a stone arch. The other new concept is shaping vaults based on equilateral triangles and regular hexagons, from hexagonal, romboidal and triangular elements shaped and arranged in a manner similar to the one used for shaping square vaults. The last innovative concept presented in a paper concerns shaping the perimeter frame from the components providing stiffness of the frame only due to topological interlocking. All presented ideas have been analised purely at a geometric level.

summary The emergence of a data space (Big Data and IoT) and, with it, the proliferation of communication means, led many scholars to describe the city through a series of concepts like the informational city, the intelligent city or the cybercity, all of them being characterized by a strong networked consciousness (Castells, Graham, Boyer). The hypothesis of this paper is that game methodology is now gaining momentum and can act as enabler of smarter communities by an increasing access to data infrastructures. This is why the city can be seen as a series of connected playgrounds where interactive tools can support citizen engagement and decision making processes. It does so by going through relevant theoretical background on gamification in the urban context and best practices, to finally describe two student projects developed at CHORA Conscious City, TU Berlin. The two projects are experimental and explore the capabilities of interactive tools in order to support planning processes.

title Toolspaces and Glances: Storing, Accessing, and Retrieving Objects in 3D Desktop Applications
source Proceedings of the Symposium on Interactive 3D Graphics 1999. pp. 163-168
summary Users of 3D desktop applications perform tasks that require accessing data storage, moving objects, and navigation. These operations are typically performed using 2D GUI elements or 3D widgets. We wish to focus on interaction with 3D widgets directly in the 3D world, rather than forcing our users to repeatedly switch contexts between 2D and 3D. However, the use of 3D widgets requires a mechanism for storing, accessing, and retrieving these widgets. In this paper we present toolspaces and glances to provide this capability for 3D widgets and other objects in interactive 3D worlds. Toolspaces are storage spaces attached to the user's virtual body; objects placed in these spaces are always accessible yet out of the user's view until needed. Users access these toolspaces to store and retrieve objects through a type of lightweight and ephemeral navigation we call glances.

summary This thesis research presents an integrated workflow for the design and fabrication of large-scale architectural envelopes using swarms of drones and inflatable structures as formworks. The work lies at the intersection of architecture, biology and robotics, incorporating generative design with digital fabrication techniques. The proposed approach aims to investigate the tectonic potential of computational systems which encode behavioral strategies inside an agent-based model. It is from local interactions taking place at the micro-scale of complex systems that a new set of architectural tendencies seem to emerge. The authors focused on the strategies developed by colonies of social spiders during the construction of three-dimensional webs. Their communication system and the characteristics of the material structure have been then modelled and translated in a digital environment. A physical fabrication process, in which the simulated agents become drones in a real world environment, was concurrently developed. The goal was to investigate the architectural possibilities given by an autonomous aerial machine depositing fibrous material over inflatable formworks and its potential usefulness in specific sites where overall conditions don't allow traditional construction techniques.

summary The building of a city model of Adelaide, Australia, has been as much determined by stakeholder enthusiasm and administrative context as technical questions. The present state of the model is comprehensive in area but exists with parts at very different levels of detail, determined by the various motivations behind their creation. The paper describes some examples of the use of sections of the model as a basis for student design projects, as a basis for City planning department-initiated explorations of development proposals, as a basis for the negotiation of acceptable development proposal strategies between City planners and the public, and as a means of presenting the implications of development proposals to City councillors who are members of the Planning Committee.

summary An overview of the research activities of a university simulation laboratory is presented. The mission of the laboratory is to anticipate the design and to support the evaluation process of urban design projects from a perceptual viewpoint through the use of digital and physical models. We have research and educational purposes. Founded five years ago, the laboratory has implemented different simulation tools, often combining existing techniques and finding new applications of existing ones. In particular, we focused our interest on visual perception tools, investigating the use of physical models and digital ones, and combining them in different ways in order to enhance the experience offered by the perceptual simulation.

title The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

summary The aim of this study is to develop a novel toolkit for co-design with community stakeholders based on the use of digital interactive simulations. The toolkit is composed of a variety of tools, with a specific focus on emergent technologies. We argue that tools, especially interactive and immersive ones, can be efficiently applied for enabling citizen engagement and supporting place-making processes thanks to the natural interaction and intuitive understanding of design schemes. The occasion for testing a co-design process and simulation techniques was the redesign of a shared public space, an initiative promoted by the project Citt? Studi Campus Sostenibile, a sustainable campus program supported by the Politecnico di Milano and the Universit? degli Studi di Milano.

summary This paper presents a methodology for the integration of fabrication constraints within the architectural design process through custom written algorithms for fabrication. The method enables the translation from three-dimensional geometry, or algorithmically produced data, into appropriately formatted machine codes for direct CNC fabrication within a single CAD modeling environment. This process is traditionally one-way with part files translated via dedicated machine programming software (CAM). By integrating the toolpath creation into the design package, with an open framework, the translation from part to machine code can be automated, parametrically driven by the generative algorithms or explicitly modeled by the user. This integrated approach opens the possibility for direct and instantaneous feedback between fabrication constraints and design intent. The potentials of the method are shown by discussing the computational workflow and process integration of a diverse set of fabrication techniques in conjunction with a KUKA 7-Axis Industrial Robot. Two-dimensional knife-cutting, large-scale additive fabrication (foam deposition), robot-mounted hot-wire cutting, and robot-assisted rod-bending are each briefly described. The productive value of this research is that it opens the possibility of a much stronger network of feedback relations between formational design processes and material and fabrication concerns.

summary New operation frameworks and user-oriented design methods are needed to make better use of new innovative technologies within smart city contexts. This paper addresses the design and research of intelligent lighting and user-oriented services for smart city environments. It presents the problem setting and research and development methods of the SenCity project. The project will pilot smart lighting solutions in six Finnish cities in different kinds of urban environments. In the pilots, the target is to employ lighting infrastructure as a service platform - an Internet of Things backbone - in the intelligent city. Together, separate pilots in different cities around Finland will create a living lab ecosystem for developing and testing innovative solutions. The specific objective of this paper is to present the concept of a platform as defined and applied in SenCity project. The presented framework forms an operational model for creating intelligent lighting and digital services in smart cities by integrating relevant technologies, users' needs, and business into an interactive system. In the paper, the framework is applied to a selection of pilot cases with specific themes to introduce its usability in real world implementations.

summary This proposed paper presents the results of a real world demo of adaptive urban lighting in a pedestrian oriented street in the core centre of a northern city of 65°01’ latitude, Oulu, Finland. The case project – LightStories (Valotarina) – explores the methods to enable city dwellers to participate in the design of public urban lighting, as well as interaction and communication through urban lighting. It applies a web-based design tool which offers city dwellers the possibility to design one hour long light animations to be displayed along a pedestrian oriented street. In addition to describing the design and development process of the lighting system and the participatory design tools used in this case, the paper presents general discussion about the process and tools, and also about the role of algorithm aided methods in enabling the user participation in lighting design with the tool.

title Situation Analysis of Design Tasks for CAD Systems
source Behaviour and Information Technology 1989 v.8 n.3 p.191-206
summary There has been little empirical research on the human aspects of CAD systems. In this paper observations on the analyses of designer activities are presented, by using a systems design approach. The paper concentrates on situation analysis and subsequent allocation of system tasks. A situation analysis was carried out in two design departments. The analysis consisted of a formal system description and a reconstruction interview. During the interview the previous week's activities were reconstructed with the help of photographs of the drawing board and protocols completed by design draughtspersons. This procedure was used for six design projects. In this study the technique of the reconstruction interview proved to be very useful and informative, and enabled three general conclusions to be made. First, designers liked the initial design phase and their responsibility for the final result. Second, they disliked the activities associated with drawing as well as the project documentation phase. Third, they preferred to work with two or more drawings on the drawing board. A number of frequent tasks could be identified, for example, large scale manipulation within and between drawings. In the final section, an example of a global allocation of system tasks for the design of a CAD system is given.

summary Drones are not just a new technology or a fun toy airplane with remote control, they are also a possible new and silent control mechanism. It would not be the first time in history nor the last in which a technological advance is used to monitor society and impress upon it the power of the State. The particularity of this case is that not only could it be misused by the government, but also some members of society could come together in an anarchic movement that, for example, could invade people's privacy, as the fact of knowing the lack of control over this type of practices.

summary This paper presents an interdisciplinary work done at the Museum Oteiza near Pamplona, Spain during 2012 and 2013. The main goal is the use of low cost devices that allows natural interaction, Virtual and Augmented Realities to get the general public closer to the works and concepts of Oteiza through interactive serious games. The most difficult Oteiza’s concepts to understand are those related with the empty space or with time & space. We propose three different activities, shaped as serious game, that use the whole body to interact and play with these concepts. The result is a facility that has been installed at the entrance of the Museum and that can be used for free, before or after a visit to the museum. These activities were presented to 4 experts in Oteiza and the results are discussed. In addition, we gathered more comments after several groups of children tried the application in the museum.

title The Grammar of Crystallographic Expression

summary This paper stems from a research collaboration which brings together two disciplines at different ends of the scale spectrum: crystallography and architecture. The science of crystallography demonstrates that the properties of crystalline materials are a function of atomic/molecular interactions and arrangements at the atomic level—i.e., functions of the form and structure of the material. Some of these nano-geometries are frameworks with special characteristics, such as uni-directional porosity, multi-directional porosity, and varied combinations of flexibility and strength. This paper posits that the symmetry operations implicit in these materials can be regarded as a spatial grammar in the design of objects, spaces, and environments. The aim is to allow designers and architects to access the wealth of structural information that is now accumulated in crystallographic databases as well as the spatial symmetry logics utilized in crystallography to describe molecular arrangements. To enable this process, a bespoke software application has been developed as a tool-path to allow for interoperability between crystallographic datasets and CAD-based modelling systems. The application embeds the descriptive logic and generative principles of crystallographic symmetry. Using this software, the project, inter alia, produces results related to a class of geometrical surfaces called Triply Periodic Minimal (TPM) surfaces. In addition to digital iterations, a physical prototype of one such surface called the gyroid was constructed to test potential applications in design. The paper describes the development of these results and the conclusions derived from the first stage of user testing.

title Design Evaluation Based on Virtual Representation of Spaces
source Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 111-120
summary When spaces are evaluated, clients and architects often discuss design proposals by looking down at scale models. This overhead perspective forces viewers to imagine themselves looking and moving about within the model. Misperceptions may well result from such a point of view. With the advancement in virtual reality (VR) technology, and with its rising popularity in architecture, it is becoming plausible to consider using VR to evaluate design projects.

The projects presented here are of three types: (1.) The first project compares people's evaluation of several slightly modified virtual models of a space. (2.) The second project compares how people evaluate a foam core model of a space to how they evaluate a virtual representation of the same space (3.) The third project compares people's evaluation of a real space to that of a virtual representation of this space. //

The wide range of results presented provides one argument in support of using VR simulations to study spaces and how they are perceived. For example, results shows that a virtual window serves to alleviate perceived crowding and that added furniture serves to make a virtual room feel slightly larger and less constraining. However, problems did emerge with using virtual reality simulations to gain information about peoples' behavioral reactions to a space. Thus, not all circumstances under which VR representations are used creates valid results. Differences appear to be in the type of evaluations measured (e.g. dimensional versus behavioral). More research is needed to clarify this issue.

Using the theoretical framework from Cognitive Psychology, we propose an evaluation model to analyze ambient information systems, considering the attentional mechanisms involved in their use. As a conclusion, we outline a set of parameters to be considered during the design of ambient information systems.

summary We will analyze a pedagogic exercise that joined together both the Informatics and Morphology Courses, required in the second year of Architecture School. The objective of the analysis is to explore the possibilities of the computer as a tool for design, and also to contribute some ideas for planning, curriculum development, and the necessary training to introduce the use of computer graphics in the Architecture School. We based our analysis on some preliminary hypotheses: (1) Students must learn to use digital models with a certain degree of simultaneity with learning design and the other techniques used to develop models. (2) Professors of Design, Representation, and Morphology are main actors in this learning process; they do not have to become experts in informatics, but have some understanding of the topic. (3) Many universities and professional associations are offering students and professionals courses based in the use of programs, instead of addressing their real needs.

The process of Design considers different dimensions, including people, technology and context, in which the prototype has a distinct role. On the way to synthesis, early solutions speculate, on a descriptive and conceptual way, about possible solutions to a given project in an early state. The importance of a clear communication between all stakeholders in the process to refine details is also studied.

summary This paper, introduces a cybernetic approach to digital design and fabrication by embracing aspects of embodied interaction, behavior and communication between designers and machines. To do so, it proposes the use of body gestures, digital/tangible interfaces and Artificial Intelligence to create a more reciprocal way of making. The goal is to present a model of designing and making as a ‘conversation’ instead a mere dialog from creator to executor of a predefined plan to represent an idea. In other words, this paper proposes a platform for interaction between two antithetical worlds—one binary/deterministic and the other perceptual/ambiguous—by focusing in the exploratory aspects of design and embracing aspects of improvisation, ambiguity, imprecision and discovery in the development of an idea.

summary Design is “something that we do” that is related to our unique human condition as creative individuals, so as “making” is related to how we manifest and impress that uniqueness into our surrounding environment. As designers, the way we impress our ideas into the material world is tightly connected to a ‘continuous creative performance’ and with concepts often missing in digital design and fabrication techniques –yet present in analog processes - such as ambiguity, improvisation and imprecision. In this paper, a model of human-machine interaction is proposed, that seeks to transcend the ‘hylomorphic’ model imperative in today’s digital architectural design practice to a more performative and reciprocal form of computational making. By using body gestures and imbuing fabrication machines with behaviour, the research seeks to embrace the concept of ‘performance and error’ as promoters of creativity and cognition about the things we create, installing human as the bond of the interrelations between designing and making.

summary In the case of designers, architects and arts, tools are part of a repertoire of cognitive, symbolic, and semiotic artifacts with which each explores and learn about design problems. Nonetheless, when using digital fabrication tools, a dichotomy between what is ideated and what is made appears as an evident problem since many of the perceptual aspects of sensing and thinking about new things in the making are neglected. It is argued that this establishes a dichotomy between what is ideated and what is executed as an outcome from that idea. How designers can think, learn and augment their creativity by using digital tools in a more relational, exploratory, interactive and creative way? Furthermore, how can we teach design using contemporary fabrication tools beyond its representational capabilities? This paper explores the richness of using digital fabrication tools through the lens of shapes grammars as a design paradigm in order to extend computational making including digital fabrication tools, gestures and material behavior as crucial actors of the design process. Through the use of discrete heuristics - that is, the elaboration of deictic rules for computation with physical objects, materials and fabrication tools in a precise yet perceptual way- this paper shows experiments inside a third year design studio to overcome the hylomorphism present in the digital design and make dichotomy.

summary Evolution and innovation in architecture are intensely related to the rise and developments of technology. Within this context, it is possible to recognize how in recent decades this milieu has fostered the development of new methodologies for urban design and architectural practice, as is, for example, the Parameterization. This paper is focused on the subject of Parametric Urbanism: discussing / questioning the emergence of this new architectural methodology; addressing the factors that contributed to its appearance; and seeking to understand whether the parametric approach has benefits and whether it may or may not be a solution or of assistance to urban planning. The paper provides a brief literature review focused on parametric urbanism and then it presents a practical case study of parametric urbanism: an Urban Plan in Beijing, developed in an academic context, at the University École Polytechnique Fédérale de Lausanne in 2012. Having as base diverse examples of parametric urbanism, it is tried to identify/justify decisions defining principles and application guidance for this project. The conclusion presents the final considerations based on opposing the case study with the theoretical approach, seeking to clarify whether this new kind of urban design methodology, Parametric Urbanism, is or not viable.

summary Computer-Aided Architectural Design Futures was conceived late one evening in the bar of the Metropole Hotel in Brighton, UK. Those present - veterans of a hundred and one CAD conferences - were bemoaning the degree to which big business was taking over the conference scene: exhibiting was replacing conferring, selling was replacing thinking, products were replacing ideas. Wouldn't it be nice, we agreed, to get back to an 'academic' conference which would take stock of current developments in CAAD and attempt to anticipate the direction of future developments and their impact on architectural practice, on the building industry and on the quality of the built environment? Four major themes are explored in CAAD Futures: (1) Systematic design; (2) Drawing and visualization; (3) Artificial intelligence and knowledge engineering; (4) Implications for practice. // Stimulus papers on these four themes were circulated prior to the Conference, and the conference papers themselves elaborated the issues raised in the stimulus papers in such a way as to encourage discussion. The resulting book, we believe, will be a major reference text for students, researchers and practitioners.

summary This paper demonstrates the process of generation of physical paper models from digital models of curved surfaces through the digital technique for approximately flattening. A collection of these models, based on works of architecture, is being produced as a didactic activity within a discipline of graphic and digital geometry in the curriculum of architecture. The study allowed the identification of parameters to improve the process of generating such models and recognize the kirigami technique as an alternative for the representation of non-developable rectilinearsurfaces, previously not included for the generation of physical models in the didactic activities in question.

source 5° Congresso Nacional de Ambientes Hipermídia para Aprendizagem, UCPel e UFPel, Pelotas, Brasil
summary Em estágios iniciais de ensino/aprendizagem do projeto de arquitetura existe um interesse de que os estudantes adquiram um vocabulário geométrico preliminar que os auxilie a compreender a forma arquitetônica. Atividades apoiadas em análises de casos de arquitetura tradicionalmente vêm contribuindo com esse propósito. Entretanto, identificam-se novas abordagens, como as apresentadas pela gramática da forma, que incorporam parâmetros sob o ponto de vista geométrico que facilitam a sistematização da atividade de análise de composições formais e arquitetônicas, tais como o vocabulário e as regras empregados. Este trabalho se ocupa em produzir materiais didáticos que reúnam estruturas de saber advindas de duas abordagens de caracterização da forma: por um lado, a representação gráfica digital observando-se o seu potencial para aprofundar os conhecimentos geométricos, e, por outro, saberes da teoria da Gramática da Forma, como maneira de ampliar e fundamentar a atividade de análise, de representação da forma arquitetônica e principalmente de potencializar processos criativos de composições formais. Apoiando-se na abordagem da metacognição, considera-se que os materiais resultantes desencadeiam processos reflexivos sobre a configuração da forma arquitetônica, ativando os conhecimentos prévios dos estudantes para projetar, contribuindo ao propósito de ampliação do vocabulário e repertório geométrico para os estágios iniciais da prática projetual. A atividade de identificação de estruturas de saber, no âmbito deste estudo, demonstra-se também como estratégia para a aproximação ao conceito de objetos de aprendizagem, quanto aos aspectos de granularidade.

source 1° Congresso Internacional de Educação a Distância da UFPel, Pelotas, Brasil
summary O aumento da produção de materiais didáticos em formato digital configura a necessidade de disponibilizar sistemas de catalogação para facilitar mecanismos de busca e recuperação dos materiais gerados. Em contextos de educação a distância, principalmente quando se trabalha com o conceito de objetos de aprendizagem, este problema pode adquirir maiores proporções, no sentido de que um mesmo material pode se decompor em várias partes, cada uma delas devendo ser indexada e ainda demonstrar as conexões inicialmente determinadas. Frente a isto, este trabalho experimenta configurar uma metodologia para a identificação de uma taxonomia que abarque um conhecimento específico, capaz de descrever e conectar objetos de aprendizagem, em diferentes níveis de granularidade e advindos de diversas abordagens. A metodologia se apóia em análises de materiais didáticos, que tratem de temas convergentes, a partir da abordagem de estruturas de saber. Através de mapas conceituais são explicitadas as estruturas de cada material, destacando-se palavras chaves capazes de delimitar uma taxonomia que no conjunto dos materiais pode ser ampliada e representar uma ampla estrutura capaz de responder às questões específicas do saber tratado. Os resultados, ainda que parciais, delimitam uma rede conceitual que expressa tais materiais, e as suas interconexões, visando facilitar sua acessibilidade, na Internet, a partir da delimitação de uma taxonomia para o domínio do conhecimento tratado.

summary Geometric knowledge increases the memory of the architect, which is formed dynamically, from new experiences on the comprehension of shape. Such process suggests the acquisition of a specific vocabulary for describing shape. With the aim of recognizing a wide geometrical and architectural terminology, experimentation is performed. The present work also describes an architectural project which uses metadata characterized by the identification of knowledge structures composed of four approaches whose geometrical and architectonical focus are present. The proposed systematization, which denotes and delimits a specific vocabulary, is considered as being able to contribute to the re-indexing of formal frameworks through the dynamic process of memory constitution to the architecture design.

summary This paper describes a process of identifying a taxonomy for describing learning materials made available in the context of a Virtual Learning Environment for Architecture and Design and produced by partner groups coming from different institutions. Paying attention to the specificity of the knowledge structure conveyed in such materials, exemplified in the case study of the digital graphic representation material, the importance of seeking by different terminologies combining concepts, techniques and technologies involved in different approaches to the same subject was observed, by allowing to characterize the structure of the teaching material and, through relationships among its terms, identify the connection between other learning objects for architectural design.

summary Creating architectural form requires much more than a moment of inspiration; it requires understanding form in its whole structure. In teaching architecture aiming for the architectural design a group of strategies is needed to prepare students for the creative process. In this process it begins with issues such as the geometry allows the students redeem their prior knowledge. This paper compares, in two different contexts of the initial stages of architectural teaching process, the results of activities of digital graphic representation of architectural structures. These activities are supported by the analysis of shape grammar in promoting the learning process in a comprehensive manner such as suggested by Wertheimer.

summary Among the many possible ways of classifying the concept of “modelling”, Maldonado refers to “homologies” when structure but not shape and function are similar; “analogies” when structure and function are similar, but not shape; and “isomorphisms” when structure and shape are similar, but function may or may not be similar. Traditional artistic representation would basically fall into the category of isomorphisms, whilst analogous models are to be found mainly in activities such as magic, play or industry. Other ways of representing reality, such as architectural models or drawings, are also traditionally regarded as isomorphisms. In the course of the last century, this panorama has been altered somewhat by the post-industrial or second industrial revolution in computing and communications. Using mathematical algorithms, the computing tool has an enormous capacity to describe things of extremely diverse nature: from the shape of everyday objects to relatively complex human behaviours, these can all be described using the common language of bits. Alongside developments in computing, the world of communications has been providing us with increasingly advanced means of transmitting information, including sophisticated systems capable of emulating our own perceptions. This paper is intended as a contribution to the theoretical debate conducted over recent years on the considerable shift that has occurred in architectural representation techniques. The analysis that follows highlights a two-fold change in traditional representation techniques: on the one hand, a change in the nature of the model (as is discussed in this paper); and on the other, a modification of the interfaces or communication and perception mechanisms of the model. The conjunction of these two factors has led to the emergence of representation modes that can no longer be regarded simply as isomorphisms of reality. Insofar as virtual spaces have the capacity for us to move, to interact, in short to inhabit them, they should be regarded as “analogous models” of architectural space. In other words, there has been a shift away from representation modes based on illusion in favour of those based on simulation.

summary Brazilian construction industry's efficiency level is very low. Within the public administration sectors responsible for the construction of public facilities, this fact is amplified by the very nature of the laws regulating the public expenditures. Transparency and active public accountability are in its initial stages, creating misinformation and opportunities to corruption. Some public initiatives of adopting BIM (Building Information Model) for public construction projects are however taking place, seeking to revert this scenario. Corruption is one of the particular problems that are to be addressed for a efficient adoption of BIM in the public sectors. In addition to the traditional corruption-fighting tools, if we comprehend all the actors and processes that lead to the construction and operation of a public building as a whole complex system, where BIM is responsible for transparent flux of information, it can provide another layer of transparency, accountability and social control over the process.

summary As a rising number of schools of architecture have decided to extend their curriculum with the new subject CAAD (Computer Aided Architectural Design) the questions of how to organize the education is deeply affecting the concerned faculty members. Though the general education objectives differ with crossing the borders it is of high interest and at the same time extraordinarily valuable to achieve an exchange of experience in the methods of CAAD-education - thus giving new stimulus to the "aged" CAAD-teachers and encouraging the "newcomers". The submitted papers were coming from many countries and they are covering a variety of questions dealing with education and practice. Research topics are touched, because the research work of CAAD- teachers always has some influence on the educational work.

summary The educational outlines used by the German, and most other European schools of architecture, have certain differences in comparison to an American school. This is partly due to the different tasks each group has to fulfill. Our architects not only plan their projects in detail, but in many cases they have to supervise the site as well. Most importantly, they also check on all communications between those participating in the design process. Skills of architects leaving their schools and entering into practical life generally need further training. Since CAAD is becoming more and more involved in architectural design studios of various sizes, the development of skills in this area should be shifted towards the period of studies. Thus, schools and staffs have to react to meet the needs of the present facts.

source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 363-376
summary Today we can look back on several years of data processing support in architecture. When computer aided architectural design - CAAD - entered the field there was a lot of utter confusion in the beginning, a lot more than usually in other more technical application-fields of CAD. The architect is a very special CAD-user, as he is a very special member of all those other very analytical and scientific faculties around. There is a lot of tradition involved, tradition that has got its roots far back in medieval and classic periods and is rich of art and creativity and intuition. Mostly lots more of this than scientific analysis, exact research, and similar stuff. We could spot a large number of architects who would have been horrified when they are confronted with the analytic research of the very basic problem as how architects are designing - the methods, the procedures and the ways of thinking. And there CAAD was entering the architects' studios. No question that this caused a lot of trouble. CAD in architecture is a very provoking subject as the new tool is going to gain ground against the tradition of centuries of handmade architectural designs and drawings. And there we don't even touch the future aspects of the computer's architectural design support - what about the imminent threat of computer support in the holy domain of architectural creativity and intuition. What about the uneasy idea of CAAD in connection with artificial intelligence? The problem of CAAD-education has been largely neglected through a number of years. If there existed a certain horror looking at the mere idea of CAD-support in architecture, horror became to outrage, when university education was discussed. In our days we can stay a good deal more relaxed, when we speak of CAAD education - we not only got used to it, we are convinced, that the whole subject is of high importance.

summary Co-operation and/or collaboration is a vital aspect in planning. Many partners have to share information and have to react - if possible - without delay. In order to get support by computers combined with modern and recently immensely improved means of communication we have to explore, how we (should) communicate and what would be necessary to support this - may be in a different or modified process - by new media. It is obvious that this investigation will be a different one, whether done by research-institutions or by highly active practitioners, who cannot afford a test-phase with non-reliable performance. This contribution tries to supply some aspects of an engineering partner within a number of project-teams.

title Parametric Modelling of Architectural Surfaces
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 635-644
summary Parametric modelling is gaining in popularity as both a fabrication and design tool, but its application in the architectural design industry has not been widely explored. Parametric modelling has the ability to generate complex forms with intuitively reactive components, allowing designers to express and fabricate structures previously too laborious and geometrically complex to realise. This allows designers to address a project at both the macro and micro levels of resolution in the governing control surface and the individual repetitive component. This two level modelling control, of component and overall surface, can allow designers to explore new types of form generation subject to parametric constraints. Shading screens have been selected as the focus for this paper and are used as a medium to explore form generation within a given set of functional parameters. Screens can have many applications in a building but for the purpose of the following case studies, lighting quality and passive sun control are the main functional requirement. A set of screen components have been designed within certain shading parameters to create a generic component that can automatically adapt to any given climatic conditions. These will then be applied to surfaces of varying degrees of geometric complexity to be analysed in their ability to correctly tessellate and create a unified screening array true to the lighting requirements placed on the generic component.

source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 685-694
summary The following paper explores practice based research as a means of identifying issues within current urban design methods. It considers the application of parametric systems as a means of addressing these issues. These systems are developed and tested across both Australian and international urban design projects within Grimshaw Architects. A methodology is proposed for the development and application of these parametric tools across multiple scales of design resolution. It reports on the application of a set of parametric urban scale massing tools in real world design projects. This exploration is carried out in distinct phases of design defined by the scale of resolution. The phasing allows for discrete problems to be addressed more effectively at different stages of the design process while still encouraging a seamless, bi directional workflow through a digital master model.

summary This paper addresses the current void between social agendas, environmental criteria and design methodology in urban planning through the implementation of new computational systems. It considers the application of digital design tools such as GIS and parametric systems towards more effi cient and effective design solutions. The digital design methods have been developed and tested within Grimshaw Architects Design Technology Group on both Australian and international urban development projects. A methodology for the use of parametric design for urban design development is suggested for defi ning, simplifying and categorising planning and design strategies. The following tools are a means of generating urban design concepts as digital forms in order to better inform the designer during the design process.

summary Architectural design is a very complicated process. It contains many sequences within the design process that the architects have to take into considerations. Within the process, the architect will look for every feasible schematic to make the best decision for developing the final design process. However, the preliminary design involves both conceptual and schematic design that concern about quantitative analysis and qualitative analysis. The objective of this research is to utilize an assistant method or tool to help form a preliminary design and a thinking process by using genetic algorithm to find the feasible solutions for conceptual and schematic design.

title Auditory collision warning signals for crane operation
source Automation in Construction 5 (6) (1997) pp. 445-457
summary This study examined the effect that an auditory collision warning signal's pulse rate, pulse pattern, and onset distance had on subject braking responses in a simulated crane/overhead power line collision scenario. The experimental warning signal alerted subjects of their proximity to overhead power lines. The experimental taks required subjects to monitor a simulated auditory collision warning signal while simultaneously operating a single-axis driving simulation task. The driving task simulated an actual crane operator's mental workload required to navigate a crane and manipulate various loads. Subjects were required to initiate braking responses based on the information conveyed solely through the auditory collision warning system. No visual information was provided to the subjects to isolate the effects of the warning signal. Subjective ratings of the auditory warning signals were obtained to compare subjects' actual performance using the warning signal versus their subjective preferences. Results indicate that subjects were able to initiate appropriate braking responses while using an auditory collision warning signal with moderate onset distances and low pulse rates. The auditory pulse pattern did not have a large impact on subjects' braking responses except at extremely short onset distances. Overall, it was concluded that a pulsing auditory warning signal comprised of a moderate onset distance and low pulse rate could work effectively as a proximity warning device for mobile cranes.

summary In order to provide a range of complex forms, justifiable to be selected in different aspects, the present work developed and evaluated a parametric and generative algorithm that allows to create diversified geometric options. The development of this work occurred in four stages, initially with the collection of information in the areas of architecture, parametric design and tools. Then the algorithm was developed with the aid of visual programming software. After, the geometric result was recreated in a physical model. Finally, we verified the potentialities of the use of the algorithm, and the use of a generative method.

summary The incorporation of virtual technologies to the learning process in architectural design is still incipient, using graphic software mainly as a rendering tool late in the curriculum. This paper presents an experience carried out with first year studio students, at the School of Architecture of the University of Chile, in which the intention is to incorporate virtual learning as part of the process spatial modification thinking. Through the use of Form Z, friendly software to learn for beginners, applied for simple extrusions, geometric transformations as translation, rotation or scaling, and the transformation of geometries and proportions through the handling of topological levels of polygonal objects. Through increasingly complex exercises we developed an effective complement of a traditional design methodology.

summary In the last decades, urban design has been influenced by its relationship with landscape. This has led to a new approach formalised and called Landscape Urbanism. Defining specific reading and analysis instruments together with proper design methods, capable of a transdisciplinary dialogue with geography, plant and biological world's languages, landscape urbanism can undoubtedly obtain more performing purposes than the ones achieved by traditional urban planning. Moreover, new digital tools are appearing, providing urbanism with new instruments for an advanced and interactive way to design cities in close relationship with landscape. The process starts with the acquisition of large quantity of data, like georeferenced maps in conjunction with relevant information about the territory, such as traffic and atmospheric pollution data, important buildings and monuments or significant landscape elements (rivers, mountains, etc.). All this information is combined onto multiple layers in order to be used by different design algorithms, connected by multi-dimensional arrays, whose reciprocal relations are dynamically controlled by architects and engineers. We will present here the case study of an ecological and regenerative infrastructure for the city of Bergamo designed on the basis of these principles, using a convenient combination of parametric tools.

summary Current research treats walkability in cities as an urban asset, to be identified by formal methods in order to let people benefit from it. In this paper, we take an activity-based view on the subject, arguing that walkability is not an end in itself but must always be seen from the standpoint of a specific activity to be performed. More precisely, we look at the specific walkability when seeking to perform an activity 'a' (e.g. shopping) within a given time budget 'b' (e.g. 15 minutes). Based on these two factors, we have devised a grid-based analysis method that computes transitions between grid cells. As result, we get a walkability map that extends the traditional 'proximity-based' understanding of neighborhoods by the notion of goal-directed pedestrians. To argue for the applicability of our approach, we showcase i it in two cities with different urban structure (Yerevan and Wiener Neustadt) before concluding.

summary The title comes from two different motives. At first it is a trial of excuse and introduces the subject of my exposure. The second reason is a way of improve dramatic accents from the beginning of my presentation. Computers are changing the world. Nobody can imagine a contemporary world without a useful help of them. We got used to the presence of computers in practically each area of existence. This presence is the first way in which computers are changing the world. The second way is less spectacular, but it completes the first one. It is an influence onto the human mentality and human way of thinking and working. This influence is often difficult to see and realize, but in my opinion is more interesting. Everybody knows that the computers are making the work of architects different. Is it a difference of quantity only or maybe also of quality? Which was the influence of computers onto an architectural space? Would it be different (better? worst?) if we were not used CAAD technology?

summary Education is an authority, it is a power. The power of independence and freedom first for teachers and then for theirs students. Teachers are responsible for an intellectual formation of students, who will build the future world. The teachers decide will they become creative people or only a well instructed members of a society. We are used to treat the education as a process of discovering and extending, but it can either be a process of covering and distributing only a selected part of knowledge. In my text I am trying to present a "picture" and a "word" as symbols of two kinds of transferring information, two kinds of culture, and education. The division line goes between teaching instructions ("pictures") and teaching ideas ("words").I am undertaking that subject because of the fact, that our life is more and more dominated by consumption, subordination to technology, and overproduction of senseless information. People are loosing theirs individuality. Our civilisation becomes very superficial and "pictorial". I belong to the "books generation", probably it is the last generation for whom the books are so important. I am conscious of that, and that is why I am trying to emphasise the importance of a "word" for a contemporary world, and for education.

summary The use of digital tools in the early, creative design process is the focus of an interdisciplinary teaching and research project. Starting from the question of how a seamless connection between physical and digital tools could be made possible, the proposed method tries to bridge the gap between both methodologies and provide intuitive, visual and collaborative design coupled with advanced, real time computer simulations. A design platform has been developed which supports a seamless connection between freely shaped physical models, GIS data and Grasshopper3D. The environment combines the reconstructed physical models with the digital one (surrounding buildings) and passes the information to a custom Grasshopper3D plug-in which serves as a link to existing and custom developed simulative tools. All simulations are performed and visualized in real time to support the intuitive and iterative design process.

summary This paper reports on a multi-disciplinary building design studio where a shared IFC (Industry Foundation Classes) building model was employed to support a collaborative design process in a studio-teaching environment. This project began with the premise that the efforts over the past decade of the International Alliance for Interoperability (IAI) to develop a genuinely operational building model schema has resulted in a mature technology that is now ready to be applied. This design studio experience sought to test that premise. The paper discusses the background to the idea of design collaboration based on a shared building model, placing this current work within that context. We look at both the nature of design decision-making, as well as the process opportunities afforded by close multi-disciplinary collaboration and rapid feedback from design analysis. Although the work was undertaken in a teaching context, the paper does not discuss the pedagogical issue, but rather concentrates on the operational issues that are encountered when working with a shared building model during a design process. The paper concludes with a statement of the lessons learnt and strategies to be adopted in future projects of this nature.

title An Urban Information Framework to support Planning, Decision-Making & Urban Design

summary This paper reports on a 2-year research project undertaken in collaboration with a state planning authority, a major city municipal council and a government-owned development organisation. The project has involved the design of an urban information model framework with the aim of supporting more informed urban planning by addressing the intersection where an individual building interfaces with its urban context. This adopted approach enables new techniques that better model the city and its processes in a transparent and accessible manner. The primary driver for this project was the challenge provided by the essential incompatibility between legacy GIS (geographic information system) datasets and BIM (building information model) representations of the built form. When dealing with urban scale information, GIS technologies use an overlay mapping metaphor linked to traditional relational database technologies to identify features or regions in the urban landscape and attach attribute data to those in order to permit analysis and informed assessment of the urban form. On the other hand, BIM technologies adopt an object-oriented approach to model the full three-dimensional characteristics of built forms in a way that captures both the geometric and physical attributes of the parts that make up a building, as well as the relationships between those parts and the spaces defined by the building fabric. The latter provides a far richer semantic structure to the data, while the former provides robust tools for a wide range of urban analyses. Both approaches are widely recognised as serving well the needs of their respective domains, but there is a widespread belief that we need to reconcile the two disparate approaches to modelling the real world. This project has sought to address that disjunction between modelling approaches. The UrbanIT project concentrated on two aspects of this issue: the development of a framework for managing information at the precinct and building level through the adoption of an object-oriented database technology that provides a platform for information management; and an exploration of ontology tools and how they can be adopted to facilitate semantic information queries across diverse data sources based on a common urban ontology. This paper is focussed on the first of those two agendas, examining the context of the work, the challenges addressed by the framework and the structure of our solution. A prototype implementation of the framework is illustrated through an urban precinct currently undergoing renewal and redevelopment, finishing with a discussion of future work that comes out of this project. Our approach to the implementation of the urban information model has been to propose extensions to ISO/PAS 16739, the international standard for modelling building information that is commonly known as IFC (Industry Foundation Classes). Our reason for adopting that approach is primarily our deep commitment to the adoption of open standards to facilitate the exchange of information across the built environment professions, but also because IFC is based on a robust object schema that can be used to construct a internet-accessible database able, theoretically, to handle the vast quantity of data needed to model urban-scale information. The database solution comes with well-established protocols for handling data security, integrity, versioning and transaction processing or querying. A central issue addressed through this work is concerned with level of detail. An urban information model permits a very precise and detailed representation of an urban precinct, while many planning analyses rely on simplified object representations. We will show that a key benefit of our approach is the ability to simultaneously maintain multiple representations of objects, making use of the concept of model view definitions to manage diverse analysis needs.

summary We report on a method that has been tested to produce the working drawings for site communication of the architectural project. The advantage of using such a method is that it allows improving the architect’s control over design while maintaining the traditional role of drawings; at the end, it will be possible the delivering of a flexible set of information more suitable to the building needs. This work is part of larger efforts to investigate the conventional methods that architects use to communicate their ideas to the builder and the potential of information technologies for partially automating this process. The research described in this paper was developed at LNEC. Funds were granted by FCT, under a Portuguese program for promoting scientific research within architecture and urbanism (PRAXIS XXI/2/2.1).

title Global Visualisation Engines – Issues for Urban Landscape Planning Participation Processes
source Digital Design in Landscape Architecture 2008, Proceedings at Anhalt University of Applied Sciences, 29-31 May 2008
summary Traditional planning processes use two-dimensional drawings, plans, sections, elevations and artists’ impressions to communicate design intent to interested parties. Three-dimensional computer visualisation technologies that support the planning process raise institutional and organisational challenges as their perceived benefits are considered. Virtual Reality (VR) models add interactivity and immersiveness to landscape visualisations but require appropriate technical input and management. This paper explores two main themes. Firstly, how interactive 3D computer simulations of planning proposals can be adopted to successfully improve the traditional process. It reports on a pilot study to examine how architects, clients, planning officers and university researchers have worked together to systematically examine and analyse this changing process. It reports on issues concerned with ownership of city models, the roles and the compatibility, accuracy and remote sharing of urban data. Secondly, we explore the emerging theme of web-based GIS applications and their impact on architectural visualisation. The process of placing urban data onto Google Earth was tested and the resulting issues emerging with this software, including IT and data management and accuracy issues for suitable architectural visualisation are discussed. The study also reports and offers an overview of placing accurate urban landscape data onto Google Earth and a discussion of using this method for online public participation and communicating technical building information.

summary Digital media and interactive technologies provide the opportunity to augment and alter the characteristic qualities of sensual and aesthetic perception. The visual and auditory senses are culturally predominant, but nevertheless the sense of touch receives nowadays increasing attention. This paper presents the perceptive potentials of touch sensations and their influences on our emotions. We will discuss how we can take advantage of these potentials using digital media and technology and how touch stimuli are forming aesthetic experiences. In this paper we are investigating the influence of an interactive "skin" - prototype on the human touch perception in the architectonical context.

summary Over the last decade digital tools became an integral part in architectural design practice and teaching. A variety of software and algorithmic methods enhance our possibilities in advanced building design. Yet our build environment is perceived with our body and senses. In this paper I present an information visualization course, which gives students an analysis method to interlace and understand the complex relationship between physical phenomena and qualitative evaluation of space. The tools and methods to achieve this aim were a combination of sensor technologies, algorithmic data visualization and phenomenological inquiry. A detailed description of the course objective, methodologies and students work are provided in this paper.

title Sensitive Voxel - A reactive tangible surface

summary Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ευ = good and άπτω = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner – potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique “touch” for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

title Adaptive Pneumatic Shell Structures - Feedback-driven robotic stiffening of inflated extensible membranes and further rigidification for architectural applications
source Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 1, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 549-558
summary The paper presents the development of a design framework that aims to reduce the complexity of designing and fabricating free-form inflatables structures, which often results in the generation of very complex geometries. In previous research the form-finding potential of actuated and constrained inflatable membranes has already been investigated however without a focus on fabrication (Otto 1979). Consequently, in established design-to-fabrication approaches, complex geometry is typically post-rationalized into smaller parts and are finally fabricated through methods, which need to take into account cutting pattern strategies and material constraints. The design framework developed and presented in this paper aims to transform a complex design process (that always requires further post-rationalization) into a more integrated one that simultaneously unfolds in a physical and digital environment - hence the term cyber-physical (Menges 2015). At a full scale, a flexible material (extensible membrane, e.g. latex) is actuated through inflation and modulated through additive stiffening processes, before being completely rigidified with glass fibers and working as a thin-shell under compression.

summary In New Zealand's (NZ) mild climatic conditions, most residential houses are ventilated naturally, mainly by opening windows. However, maintaining the indoor thermal comfort characteristics of a house by modulating natural ventilation is particularly challenging, as the solution is not explicit. Determining a solution requires a technique that adjusts openable window area while encapsulating the complexity, dynamics, and nonlinearity associated with the natural ventilation driving forces and building thermal behavior. By verifying that there exists a significant potential of regulating indoor thermal comfort of a relatively airtight and insulated house by adjusting window openable area; this work additionally confirmed an excellent capability of Artificial Neural Network (ANN) technique in predicting air temperature time-series of the naturally ventilated house. On the basis of these examinations, this work particularly developed a co-simulation strategy between building thermal-airflow model and the ANN model and demonstrated that windows could be regulated intelligently to modulate the natural ventilation and maintain indoor thermal comfort level during the summer period by applying Artificial Neural Network (ANN) based predictive controller technique.

summary Typical horizontal building types, open spaces, and human activities have yet to competently overcome or adapt to the constraints of vertically-oriented dense urban environments. Designing the built environment to the oblique, or more than two axes at once, is a required strategy for the future of city planning, the advancement of body-space interaction in architecture, and to reinforce the interconnectedness of the natural environment with human activities. With the development and increasing use of 3D modeling software, parametric and generative design processes, and the progressive investigation of complex geometry, it is likely that the oblique will be envisioned more and more as a functional architectural device. This research investigates the tessellation of minimal surface geometry to achieve a folded, multi-use surface capable of connecting disparate urban program and which can enable a city to offer amenities that are typically available in horizontally-oriented suburbs. The geometric family of the helicoid is found as the optimal formal generator because of its ability to create a continuous surface while allowing for both horizontal and vertical circulation.

summary This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title Built Form Impact Assessment Method of Description
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary Continuous change in contemporary cities heve produced an urban space tipollogically diverse, particulary in fast growing South-American countries. As a result, the straight contextual analysis, usually used to assess the degree of innovation/permanence of new buildings in urban settings becomes ineffective, for the simple reason that frequently it is virtually impossible to establish what the context dominance actually is. The method proposed in this paper takes the issue of tipological analysis from a systems approach. This is carried out by a series of procedures, such as: a) identifying buildings'constitutive parts, which can be done at any degree of detail; b) listing them according to their attributes of repertory and formal composition. ;with this it is obtained a extensive catalogue of the entities taking part of the considered urban setting, from which the actual context can be depicted; c) listing each entity's participation in the landscape composition, or the role each one has in the landscape configuration. The software that operates the analysis does the rest, measuring the degree of innovation/permanence of each entity, in relation to the others, and defining what the context is made of.. From this, any inclusion/exclusion in the considered townscape is automatically evaluated in terms of impact on the pre-existing setting. The system can be used at any urban scale, as well as at the building scale.

summary After the wide-spread use of computers as task processors, either for algorithmic operations, or for advanced interfaces, the emphasis has shifted on computers as communicators. Beyond basic serial communications, computers serve as providers of information, linking organizations and expanding the bounded rational of professionals. Based on the use of computers as communica-tors, a multiplicity of visual databases for architecture have emerged in the recent years. Building on a maturing technology, those databases address different domains of design, either aiming to provide the designers with information for making informed decisions, or aiming to document prior designs. However, a common characteristic of those visual databases is a separation between the design of the database, versus the entering of the critical amount of data that can make the databases useful. While the research has progressed in the designs, and technological problems of data presentation and data transfer have reached workable solutions, most of the efforts have not succeeded yet in providing the critical mass of information that is required to make the use of the databases desirable. Furthermore, this effort seems as having less research interest, while the necessary amounts of data, and especially the updating of those data, makes the task impossible for academic institutions, and requires interorganizational efforts. This paper focuses on the duality of the databases, either as a form of documentation, or as on-line interactive information systems. Based on that distinction, it examines the required technology and the critical success factors of each type, and proposes that these databases add value to design and they have considerable market effects, which will drive their development and diffusion.

summary The present study tries to investigate the Brazilian hackers´ artistic and communicational manifestations. We tried to understand how they use the digital technology for expression of their identities and transmission of messages in defaced homepages. The integration of different chains of thinking made it possible to build a schematic diagram and the establishment of conceptual categories for a graphic analysis and for the analysis of the messages present in the defacements by the Brazilian hackers. From these analyses we could see that the Brazilian hackers express their identities through their nicknames and defaced pages. These pages have a common underlying structure marked by the linearity, the identification of the one(s) responsible for the defacement, the message left for the administrator of the defaced page, the personal statements and the exhibition of the elements for contact with the defacer(s).

summary Differently from other regions in the Planet, since 2010, in Latin America textual programming language (Rhinoscripting) is being replaced by its visual equivalent (Grasshopper). This is a consequence of our preference for an interactive platform, and because our design problems are not as complex, so we aim to control geometrical problems or aspects belonging to an product scale instead of an architectural one. Problems emerging when creating code could be improved by modifying and reusing existing solutions as a starting point, since learning would not be centered in the object but in the process of creating it, using a suitable instrument.

summary A great part of our physical environment and existence is currently undergoing an epochal transformation from a solid to a liquid state on many layers of technological evolution. Optical phenomena and radical shifts in visuality, particularly manifest through media propagation are impacting on urban space in unpredictable ways. City - space is not only perceived as a physical place but also simultaneously inhabited as a virtual site. Both conditions form the hybrid of an urban realm, construed as surveillance, simulation, distraction and a relentless proliferation of information. Ultimately, all man-machine interfaces of hardware will be adequately infinitely machined. This process however will continue beyond the now experienced level of TV, video, cellular-phones and computers, incorporating interconnected surfaces of text, music and other kind of data. The surrounding sensorium will penetrate the phenomenological tissue of our nervous system to the extent that we are unconsciously fluidly interacting. Behavioral properties of matter and their smooth transmittal of visual, sound and tactile sensations, will provide an intellectual and sensual presence which renders space and its perception as being liquefied. Also the interrelation between the exterior and interior usage will be smooth and multidimensional, as the building’s envelopes are capable to alter their properties in response to contextual changes or movements. A redefinition of the disciplines of architecture and urban planning responds to the changes in cultural, social, political and economical milieus.

summary A person is a wonderful creature. His high organization helps him not only to see and to hear the world around him, but to feel and understand, to condole and pity. A person is a sacramental creature too. His complex organization helps him to see day as light and darkness, as delivery and death, as delight and grief. Every human reaction has biological, physiological and sensitive components. That is why environment is able to call up physical an emotional associations. A human being can "see" sound and "hear" colours. All history of human culture shows that the art can affect man in different ways: unconscious effects, spontaneous associations, general symbolic or specific conventional meanings. That is why architecture can not only protect (a safeguarded aspect), but give knowledge ( an informational aspect) and set up mood (an emotional aspect). And that is why we speak about ambiguity of sense and about multiartistic works. Such as Skriabin's symphony 'Prometheus'. Two scores - musical and colouristic - are connected in this masterpiece. Let us look through two architectural disciplines—from this point of view. The programmes of these disciplines are examples of such embedment. Any architectural discipline demands computer graphics. Any architectural discipline demands multimedia aided teaching, because multimedia in computer designing is a result of human being's complexity and ambivalence.

summary There is an absolute dependence between the professional colour culture and the sphere of professional architectural tasks. From the skill to know how to handle brush up to the skill to convey one's own conception to the customer. Colour sketch, polychrom model, means of computer aided design, colour schemes and diagrams, are the means, which modern architect must wield. Actually an architect must think "by colours" from the very beginning of designing and must use colour as a compositional expedient. Architectural colour theory gives the students of the architectural department fundamental rules of colour science and methods of their practical utilization. But today the real designing demands the wider utilization computer of the graphic. There are a lot of remarkable graphic packages, which help architects to wield vector-mode graphic display and roster- mode graphic display, to work with colour and shape. That is why it is necessary to teach students to use the possibility of computer designing in the field of architectural colour science. This task determines the general matter and direction of teaching programme, defines the character and the way of its composition, The teaching programme is adapted for using the graphic package "Corel DRAW-5.0". Students work with a simple set of software tools "Corel DRAW" and at the same time acquire habit of working with the graphic package and decide problems of plane and volume colour simulation. The main practical tasks - colour on perception, psychological influence of colour people, colour harmonies, are performed by the way of "colour modelator". With the help of uncomplicated transformations it helps to receive a necessary set of simple figures for colour exercises.

summary Urbanisation carries in substantial variations in human life, such as the bad air, dirty water, heightened radiation which are the main reason of the hygienic discomfort. But this is not only ecological problem, there is one more - the visual discomfort. Human being is forced to live in the environment of huge flat areas with straight lines, right angles, and uniform painting. The visual comfort is related to natural world of trees, mountains, includes acute angles, crooked lines, colour diversity. That is an environment with a great variety of natural visual elements. Ecological expediency is obtained when colour environment possess the informational sufficiency and provides emotional and visual comfort.

title Designing the Undesigned: Emergence as a tool for design
source International Conference on Generative Art
summary Design, as an act and a result, is a natural part of the larger biological context in which we live. It is both a behavior and a tangible side effect of the organic system from which it arises. A design can be characterized as a physical exemplar of the concept of memes, the 'genetic' building blocks of ideas or units of cultural transmission. In this capacity, design has served to extend humankind's reach and ensure and enrich humankind's survival in the full range and variability of conditions the Earth has to offer. In a very real sense, design has 'evolved' its own rich ecosystem, with a robust diversity of elements, dynamics, and interrelationships rivaling that of the organic system from which it derives. In the ecology of design, designs obey laws analogous to the laws of survival and selection that organisms in nature obey. Given the recent advances in understanding and modeling of the biological and physical systems, it is not surprising that artists and designers are now turning to these models as a 'new' resource for the conceptualization and design of structured artifacts and spaces. While there are many fundamental technical issues surrounding development and application of generative models and processes, the relationship of artist to the process of creation is a central issue in the scaling up and widespread accessibility/acceptance of the generative approach. This paper will present a set of observations from the perspective of a small company of artist/ technologists trying to bridge the commercial and artistic application of generative processes. Specifically, the paper will explore some approaches to the designer/system relationship and process control metaphor, the balancing of serendipity and design convergence, the definitions and representations of design spaces, and finally, present some ideas about the future prospects and promising new techniques for generative design.

summary Propose: Costs are a major issue in low-cost housing projects. Traditional project process uses estimated cost studies and comparative methods in initial phases, but the cost itself is elaborated only at the end phases, generating significant re-working and changes in specifications and drawings. Is desirable to use tools that possibility more integration between costs and architectural projects. Some CAD software already offers these tools, but they are not use by architects. This work intention is search in these tools the integration between costs and architectural projects. Methods: To use software Vectorworks in a low-cost housing project, Residential Serra Verde; incorporate cost aspects at initial phase by parameterization of 3D model; analysis of cost and project results. Findings: validation of cost estimative with the utilization of tested procedures. Value: developing a simple methodology of cost estimation and integration with architectural project.

summary A design process is traditionally viewed as a sequential process model from the formulation of the problem to the synthesis of solutions. Simon (1981) regards design as a state-space search where a problem leads to the solution. To be more practical, there are many versions of solution generated during design, where each current one is an improvement over the previous one. This kind of synthesis of solutions can be viewed as an evolutionary system over time. We propose to apply the metaphor of "exploration” to design, and further argue that evolution occurs in the problem space as well as in the solution space. Co-evolutionary design is introduced to remove the assumption of having a fixed goal (problem). The problem is allowed to change over time. Two algorithms for co-evolution are presented. Their characteristics and differences are highlighted. The paper moves on to review the design history of the Sydney Opera House and to show how observations from this real life example confirm our co-evolutionary model.

title Ratios for cost control
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary The design of buildings takes place in phases representing a development from rough to precision planning. Estimates are made in order to test whether the result is still within the budget set by the client or developer. In this way, the decisions taken during the design phase can be quantified and expressed in monetary terms. To prevent blaming the wrong person when an overrun is discovered, the cost control process has to be improved. For that purpose, two new procedures have been developed: (i) a new translation activity; and (ii) ratios by which quantities can be characterized. 'Translation is the opposite of estimation. A monetary budget is converted -'translated' - into quantities, reflecting the desired quality of the building materials. The financial constraints of the client are thus converted into quantities - the building components used by the designers. Characteristic quantity figures play an important role in this activity. In working out an estimate, the form factor (i.e., the ratio between two characteristic values of a building component) has to be determined. The unit cost is then tested against that ratio. The introduction of the 'translation' activity and the use of characteristic quantity figures and form factors enhance existing estimation methods. By implementing these procedures, cost control becomes considerably more reliable.

summary We present a tool which empowers 'green' design freedom for architects by presenting ever expanding choices in components and materials and automatizing their configuration and placement. Several time- and resource- consuming initial design iterations are eliminated by optimizing the energetic efficiency of the building in the original draft phase. The smart, efficient, energy producing building of the future can thereby offer increased cost and energy efficiency, security and comfort, without any compromise in style and form - on the contrary, the proposed tool stands to open up a novel palette of creative 'green' architectural design elements, which would effectively be co-designed by architects. The proposed algorithmic CAD design tool allows direct integration of renewable sources in the architectural design phase, taking into account local meteorological and solar radiation conditions. Furthermore locally optimized evolution and modification of renewable components integrated into the building's structure is possible, leveraging an increasingly wide range of possibilities in form, finish and renewable energy generation.

summary This paper reports on some recent research carried out to develop computational generative urban design system that can be used as an alternative approach to master planning. The focus of the investigation is an 11 ha site located in the South-East edge of Auckland, New Zealand. The urban (or sub-urban) morphology is modelled as cellular automaton based on Hillier’s (1984) x-y syntax in order to resemble the morphology of the existing village. An agent based system based on Reynolds’ (1987) flocking algorithm evolves synchronously with the automaton and tests its ecological fitness. The emergent pattern of development therefore results from the mutual co-adaption of the cellular automaton and the agent based model. The outcomes are variety of spatial morphologies that connects well with adjacent existing village and at the same time take into account landscape and ecological peculiarities of the site.

source Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 316-353
summary We propose a prototype “kernel” of an object-oriented language, SOML (Scene Objects Modeling Language), intended to assist in the declarative design of scenes in image synthesis. This language is an attempt to provide the designer with a tool to facilitate the rapid prototyping of 3D scenes. It can also serve as a tool for knowledge acquisition and representation , and for communication and exchange of data with other tools in a design environment. Advantages offered by the implementation of SOML are: (a) from user’s viewpoint: the possibility of declarative description of the initial concept associated with the target scene in terms of properties and constraint vocabulary, the possibility of quantitative and qualitative reasoning on these properties, the modification of the intermediate solutions to different levels of detail, the utilisation of previous solutions; and (b) from the implementation viewpoint: the structuring of the properties and methods in the form of domain knowledge, the optimal solution generation according to heuristic causal-probabilistic criteria, the transformation of the semantic concept description of the scene in generic entry code for a geometrical CSG modeler or for rendering and visualization software, the integration of functionality for parameter generation and modification, the compilation of a scene from components of other final scenes and operations of geometrical transformations acting on groups of scenes. We present the architecture of the object-based implantation of the language and its interpreter, in the unified notation formalism UML. The utilization of the SOML language is illustrated by some examples.

summary This paper discusses methods for information management through the rational application of IT within collaborative design. We explore the possible integration of the platforms of case-based reasoning and information structures. We examine the potential combination of existing techniques (CAD-tools, word processors, general applications, WWW) and standards (IFC, national classification systems) into a system for information management. We focus on the designers’ use of heterogeneous information and the further development of a prototype based on product-model and process-model technology. Today, XML helps us structure various kinds of information before the system performs case-based reasoning sessions. The aim is to promote efficient and flexible information management in a casebased design process. Through the use of standardized product models, this information will be sharable and suitable for reuse and feedback. The more often the information is reused, the more general and adaptable it becomes i.e. it evolves. This scenario requires, though, efficient information management in the design office: a quality system for evaluating the information for reuse, consequent use of standardized product models and IT.

title Model of Design Parts and its Use to the Design Team

summary This paper discusses the impact of the choice of representation on the final result in design and construction projects. Representation is an integrated part of the design process used by architects as a communication tool to help them present a concept to their clients and other consultants. The representation choice, in addition, reflects the professional’s perception of the design process and the architectural artefact. Architects’ offices work with a wide range of problems - aesthetic and spatial issues, detailing, choice of materials, and systems design. The multiplicity of representations enriches the understanding of these issues. Today, the model-oriented approach in design is common among both architects and leading software producers for the construction industry. While STEP (Standard for the Exchange of Product Data) aims at developing very comprehensive product models, we examine the possibility of building up a small-scale model responding to the information needs of a design team. In our research work, we view a model of design parts as a suitable carrier of information allowing the designers to store data reflecting their accumulated and refined professional knowledge and experience. Besides, the team of architects can later easily retrieve information needed for future design reuse from the model. To reuse design solutions and learn from previous work is an essential part of the professional culture. The construction industry as a whole has been slow in implementing information technology to improve the work methods. Neither have architects’ offices used the full potential of this technology to structure information and rationalize the design process. The objective of this study is to examine whether information technology makes it possible to organize all the design information in an office archive. The proposed model of design parts relates to national standards and universal models for product data representation and exchange, such as STEP. Today, the construction sector is becoming increasingly aware of the potential of the model-oriented approach both to rationalize the design and construction process and offer designers new options to store, broaden and reuse professional knowledge. We have used the information modelling language EXPRESS to describe our concept.

Mais il semble que la société moderne ait déjà omis pour toujours la première voie : au réseau télépathique, nous avons privilégié le réseau télématique. Il est difficile d'évaluer les conséquences sociales et psychologiques d'un tel choix. Néanmoins, la prudence nous oblige à garder notre autonomie de la technologie. Alors, il faut la maîtriser au fond, et surtout former la génération future de façon non seulement pratique mais aussi philosophique et critique par rapport à elle.

source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 209-216
summary How we see things depends on our education and our cultural pre-suppositions. This does not allow to convey some logical form, but nevertheless makes possible a more global and less formalized understanding of the objects, their environment and their physical proprieties. In architecture, the digital image acts according to two directions: (-) representation: the fine images are a means of communication between the different parties implementing building projects. (-) modelization: in addition to its iconic qualities the layers of different models simulate the most different aspects of the ,image and the environment characteristics. // At this level our vision is directly concerned with the design of the studied object; it acts both in the design process and in the expression of our conceptual images. How does modelization work? Infographical representation deals with a more or less schematic and conceptualized world the reading of which is more typified than particularized. It deals with a schematization nearly "ideographical" of the mental image thus is produced "synthetism", a neologism similar to such expressions as realism or abstractionism.

title "To See Ideas" or The Visualizing of Programmatic Data Reading Examples in Architecture and Town Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Whether images are still in the mind, metaphors, sketches or icons, they play a crucial role. They have always been the heuristic pivot around which the process of artefact design organizes itself, particularly in architecture and town-planning. "To see ideas" through computer ideograms is to experiment an interesting and new direction for "pictural approach" supported design. Cognitive psychology emphasizes the important part played by mental images in reasoning, imagination in the working of human intelligence and the construction of mental images as cognitive factors underlying reasoning. It also points out how close computerized objects and mental schemata are. "To reason over a situation is first to remember or build some mental models of this situation; second to make those models work or simulate them in order to observe what would happen in different circumstances and then verify whether they fit the experiment data; third to select the best model, a tool meant to sustain and amplify the elaboration of mental models, which is a spontaneous activity". We introduce our exploration of the direct transmission of mental models through computer ideograms. We study the "operative" and the "expressive" aspects, and this allows us to analyze how some aspects in a field of knowledge are represented by ideograms, schemata, icons, etc. Aid to imagination, reasoning and communication by means of a graphic language must be limited to some figurative relevant aspects of the domain considered; it should not aim at a realistic simulation. Therefore, the important role played by icons and the spatial schematic representation of knowledge is emphasized. Our hypothesis is that an architectural concept does not result from an inductive process, but rather is built to solve problems through the direct representation of ideas with ideograms. An experiment was conducted with a graphic language, a dynamic scenography and actor-objects. The language allows one to build and visualize models from the various domains of knowledge of the object. The dynamic scenography can explore and simulate kinetically those models by means of staging various narrations and visual scenarios. The actor-objects play various and complementary parts in order to make the image explicit and link it with the concept. We distinguish between two parallel levels of reality in computer ideographics: one concerns the model, it represents the visualization of a graphic model at a particular moment and according to a particular representation, the other concerns the ideogram.

summary Reflection about the architectural programme starts with the analysis of its writing, its "style" which bears not only the "griffe" of the programmer but as well the structure, methodology, codes of reading, etc. particular to a programming approach. The programme structure corresponds in most cases to the different levels in the text's format and the composition modes of representing data and their relations. The choice made can either facilitate or impede the reading as interpretation of the programme. The programmer’s aim should be to open the text to reading towards a "synthetic schematic" summary, a sort of cognitive threshold which allows the reader to understand both the client's objectives and the designer's intentions enhanced by his experience. Articulating a designer's experience means focusing on his knowhow and memory. The designer's recollected knowledge and heuristic approaches to the solution of a basic design problem - types, his readings and spatial evaluations permanently feed the knowhow. It is important for the architect to have access to past examples, to the collective memory of his workplace, and a repertoire of readings, notes, sketches, influences and citations. It is therfore equally important that a computer environment also have a multimodal "architect's memory" or "project memory" module in which different forms of representation are classified, and made accessible as memory components. It is also necessary to have the possibility to access at any moment in an interactive manner to the recomposition, addition and adaptation of these mnemonic components. The information coming from the programme, classified as descriptive, prescriptive and quantitative types of data, must be able to be interrogated in different modes of representation : text, matrices, nets, diagrams, and so on, so that the pertinent information can be extraded at any given design process stage. Analysis of competition programmes show that often the description of an activity, for example, the Great Stadium competition in Paris, is described by several pages of text, a circulation diagram with arrows and legend, a topological proximity diagram with legend and as table activity - areas . These different representations, which are supposed to be complementary and give the most pertinent view of the client needs, show in fact after analysis, many description problems, incoherance, and which result in a reading difficulty.

summary Our fashion of thought is dialogic in its way to use simultaneously logic- mathematics and analogical approaches (Morin, 1986). The analogy works as well at the level of the unconscious by the construction of an analogon that permits us to recognise a face between thousand of others, despite changes intervened in time; as consciously where by an effort of constructive analogy, we establish bridges between different events or domains giving to the design a new lighting that puts it on the way to a solution. For this reason visual approach acquires a great importance in the establishment of similitude in conception. Many testimonies of scientists, philosophers, artists confirm this observation about their creative work, while underlining the danger of no founded analogies. In current life, analogy brings a support of likeness to the daily conversations, and the possibility to advance in the dialogue by a chaining of analogies having for objective to strengthen the speech.

summary Calculations are used to forecast urban flows of population, development of various activities, demography, and many other architectural programme constrains, and have been spontaneously the first field of computer intervention in urban and architectural project design. By analogy to engineering where computation is the base of decision making, architectural design process is seen as a problem solving process. <> constrains computer aided computation is seen as Computer Aided Architectural Design, CAAD. This way, a technological utopia called CAD in architecture is born. Nevertheless, the review of architectural design methods has clearly shown that programmatic models, since they are only used to evaluate spatial hypothesis, and do not have in themselves space production potentialities. In spite of the powerful methodological movement of the sixties, that have established this design constellation, the misunderstanding persists until now. Architect is a gestural and visual being. By using simultaneously metaphor, gesture and calculation, he calls for all his experiences and sensibility to realise plastic and poetic synthesis of form. To remedy to the major problem of the form synthesis, graphical instruments have been proposed. Why not utilise tools used in the field of engineering as computer aided drafting ? And so, computer aided drafting triumphaly entered the architectural design process. But, computer aided drafting is commonly seen as an instrument used on the - projection - stage, where drawings are produced for an already designed object. A new myth that assimilate architectural design to the drawing production activity arrives with the <>, containing thousands of drawings. All this aimed to facilitate, as it is proclaimed, communication between all the intervening in the project.

Thanks to that, architecture that was never thought as a scientific discipline seems at last to enjoy a virtual laboratory of pure research. This visionary space of experimentation of potential architecture must assure the return of performances obtained in the constructed environment. But, to make such a future certain, one has to start with pedagogy, where the laboratory of potential architecture must constitute a real construction site of the imaginary.

summary The projectual disciplines must respond with some grade of originality to a approached problem. In order to products of design be creative must be implemented a creative process of design and also from the teaching. The essence of creativity are the variations over a subject. A pedagogic way for this, is the one to recognise, individualise and represent the problem attributes, building upon them an "exploration space", to analyse and create new combinatorial alternatives or restructuring of the problem. The digital media incorporation as a new proyectual environment approaches the interactivity not only of the combinatorial variables, but, also to the hypermedia's. Both the digital documents, as the creative process, have a "no linear" or a "net" structure, that allows the construction of a himself way, self-managemented into this structure. The interactivity makes possible to work, as the divergent thought does, in a "polydirectional" field, that stimulates the fluency, the flexibility and the originality. The new- media's, used as didactic tool, open to "action", allow the students to convert them in "co- author", together professors, about themself learning process. >From this educational conception and its potential enrichment with the hypermedia, we are designing a project of digitising of an exercise to our didactic proposal and its later application into the course with our students.

summary The textile surface presupposes infinite limits and contained in each one of its minimum parts the total information of the complete system, the singular sign that repeats itself with infinite criterion in a limited field. The textil proposes, simultaneously, the limit and the excess. The logic of the constructions by repetitions is based in the coordinated interaction of the part and the whole. IT CONSTITUTES A SYSTEM, with variations from simplicity to complexity, in the estructural morphology and in the surface. The recuperation of a totality/ continuity concept in a teaching- learning strategy, implicates the manage in all senses of a multidirectionel space, today indispensable, in the convivences of the analogic and the digital. Immersed into a culture that repeats the fragments on a seduction of the representation to the representation itself, the generation of a place of flexibility and interaction is the instance to the knowledge construction.

summary This paper briefly reviews the state of the art in computer drafting. It moves on to consider some of the limitations of computer drafting systems today. It poses a number of questions regarding the trends and future development of the subject, and suggests some points which should be addressed by the vendors and user organisations alike. The paper concentrates on marketing and management matters rather than on purely technical issues.

title An Empirical Investigation into the Influence of Media Types on Design Cognition and Methodologies
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary This paper reports on the findings of an empirical investigation into the impact of different media on design methodology. The statistical sample included 49 fourth year architecture students, divided into three groups: the drawing group, the physical model group and the computer group. They were given a problem of designing a façade in an urban context in Glasgow over a two week period. The design process of each group was monitored over that period through observations, recordings and attitude measurement via a questionnaire survey. The results were analysed using the Statistical Programme for Social Sciences (SPSS). The dendrograms from cluster analysis revealed that there were well established perceptual dimensions, or clusters, for the façade’s design variables within the three groups because of using different media. The impact of media on design creativity, both as a process and a product, was investigated. All three media types yielded a positive correlation between ‘media made design decisions more creative’ and ‘media made design scheme more creative’- with a correlation coefficient of 0.708 which was significant at the 0.01 level, p<0.05.

source SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 125-128
summary This work stems from our research on augmented reality (AR); it is focused on the development of AR applications for smartphones. This research was motivated by many factors including the reality that: mobile phones have become commonplace in our societies, there is high demand for access to real - time information, and that smartphones are practical, powerful, and compact devices that are available in developed as well as emerging economies. In light of such facts this work presents a case study and proposes the development of an application capable of linking the most remarkable features of smarthphones (GPS, camera, accelerometer, internet access, and compass).
