title	Responsiveness and Social Expression; Seeking Human Embodiment in Intelligent Façades
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 12-23

summary	This paper is based on a comparative analysis of some twenty-six intelligent building facades and sixteen large media-facades from a socio-psychological perspective. It is not difficult to observe how deployment of computational technologies have engendered new possibilities for architectural production to which surface-centeredness lies at that heart of spatial production during design, fabrication and envelope automation processes. While surfaces play a critical role in contemporary social production (information display, communication and interaction), it is important to understand how the relationships between augmented building surfaces and its subjects unfold. We target double-skin automated facades as a distinct field within building-services and automation industry, and discuss how the developments within this area are over-occupied with seamless climate control and energy efficiency themes, resulting into socially inert mechanical membranes. Our thesis is that at the core of the development of automated façade lies the industrial automation attitude that renders the eventual product socially less engaging and machinic. We illustrate examples of interactive media-façades to demonstrate how architects and interaction designers have used similar technology to turn building surfaces into socially engaging architectural elements. We seek opportunities to extend performative aspects of otherwise function driven double-skin façades for public expression, informal social engagement and context embodiment. Towards the end of the paper, we propose a conceptual model as a possible method to address the emergent issues. Through this paper we intend to bring forth emergent concerns to designing building membrane where technology and performance are addressed through a broader cultural position, establishing a continual dialogue between the surface, function and its larger human context.

summary	Traditionally, the teaching of digital design systems has been focused on the operative learning of software. However, this almost exclusively technical approach has leaded to a partial view of these systems, as well suited platforms to exploration of project’s possibilities. Consequently their relevance as a base for project representation and therefore as a useful instrument for conceptual exploration for design and experimental research of their processes have been undervalued. On the other hand, this restrictive perspective results in an important waste of the teaching possibilities lying in CAD software related with interdisciplinary teamwork. The following academic experience obeys to a new insight of how to teach these tools, based upon problem solving in Design by interdisciplinary students work teams from Architecture and Industrial Design. In this bet, the learning process is flexible, shared and collaborative, according to the requirements of each project, powered by the commitment of facing common goals. [Full paper in Spanish]

title	A Design Model Using Mutation Shape Emergence
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 41-50
summary	The ability to recognize properties and characteristics unforeseen in the early stage of design, namely shape emergence, is considered one of vital aspects of human visual perception in creative thinking. This study aims at developing a design model by using an extended theory of shape emergence, mutation shape emergence which we call. The first part of this paper describes the definition of mutational emergent shapes clearly. In the second part, possibility of discovering mutational emergent shapes will be explored through protocol analysis. On the basis of the results of these efforts, we will examine closely the cognitive mechanism to discover mutational emergent shapes. In the last stage, based on our results we propose a design model for understanding the cognitive process implications for training architects.

title	Analogous Models and Architecture

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.

title	A Multi-dimensional Exploration of Urban Attributes by Data Mining
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 333-350.
summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title	Interpretation of Implicit Design Knowledge in Architectural Drawings Into Explicit Knowledge
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 23-32
doi	https://doi.org/10.52842/conf.caadria.2005.023
summary	This paper concerns a methodology in applying architectural design knowledge to the interpretation of design concepts from architectural drawings. We formalize the design knowledge such that knowledge plays a key role in the design interpretations that map between drawings and their design concepts. We consider this mapping, in general, as those linking between design decision space and design performance space, where design variables in both spaces are examined and categorized from the drawings and concepts. Examinations on drawings are performed based on qualitative shape analysis schemes and we apply feature-based shape analysis techniques to encapsulate those design characteristics in decision space. Interpretations of design concepts through shape characteristics are based on mostly two types of symmetries, namely cyclic and dihedral groups. We use CommonLISP in analyzing shapes in design decision space and CLIPS expert system shell in illustrating simple reasoning based on those design knowledge. We select target drawings from some of Frank Lloyd Wright’s block housing plans. In this experiment we try to illustrate a valid methodology that explicitly handles some of the implicit design knowledge hidden in architectural drawings.

title	Representation and Typological Refinement in a Case-base

summary	The subject of the paper is the possibilities and limitations of domain knowledge in design computing, as experienced in the development of a case-base of school buildings. In case-based design domain knowledge is used not only in the documentation and analysis of the cases but also in the structure of the casebase. The cases were documented and analysed using a geometric and topological representation. With respect to typological classification the highest abstraction level was occupied by three established types, the corridor, hall and pavilion type, which represent practically all school buildings in our case-base. Progressive abstraction of the geometric and topological representation returned the components of each type at various levels of specificity that correspond to different levels of design thinking and decision taking. The resulting typological / case-base structure provides a transparent description of both parts and global arrangements and has led to the identification of subtypes, variations and hybrids.

summary	In landscape architecture design, land forming is the key to trigger many design concepts. However, the design media we currently used doesn’t provide suitable data or better visual feedback to designers when they are on site. In this paper, we develop a framework as well as a ubiquitous device called MODA comprised of five components. They are sensors, representation, display/viewing, motion and control that result from behaviors observation and analysis. According to the framework, a practical example of landform design is conducted and examined with one version of MODA combining both hardware and software.

title	Sensitive Voxel - A reactive tangible surface
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 525-538.
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 ŒµœÖ = good and Œ¨œÄœÑœâ = 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 ‚Äì 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 ‚Äútouch‚Äù 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	Supporting Objects in voxel-based design environments
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 105-113
doi	https://doi.org/10.52842/conf.caadria.2005.105
summary	Inspired from the idea of using voxels in the conceptual stages of architectural design, a synchronous collaborative design system, CoBlocks, was developed. This paper raises the problem that simply adopting the voxel representations would take voxels as graphic primitives and offer design operations at the voxel level. We introduce the object descriptor to group voxels to form higher-level semantic elements. A test of its efficacy is reported in this paper. The results indicate that the objects facilitated more discussions on high-level design issues and supported more effective design operations. This suggests designers can benefits from the use of objects in voxel-based design environments.

title	Diagraphics: an exposé of visual expression
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 400-404
summary	This exposé introduces preparations for a publication based on what I have found to be a ‘missing link’ in the library of educational source materials. The skills necessary to record and interpret the complexity of the architectural design process are often illusive. The sophistication of computer modeling and graphics applications only adds to the dilemma of making clear and concise decisions about how to communicate the essence of one’s design intent. The publication will define and illustrate five Diagraphic models of analysis. Each offers ways of seeing and understanding the idiosyncrasies of recording the design process. Gestures, Traces, Pulls, Morphs and Transits exemplify specific modes of visual expression and integrate both their diagrammatic and graphic nature. The distinctive aspects of each model enable the student of architecture to choose appropriate and meaningful techniques for visual expression. The publication will also illustrate current and historically relevant examples of diagrammatic expression. These examples show how diagrams have been flexible over time in adapting to the needs of newly forming conceptual models, spatial analysis and belief systems.

summary	Cities are becoming more complex in this digital era due to technological changes. Thinking of cities without such technological changes is equivalent to an embryonic state in the morphology of city growth, that is, the growth seems less advanced. So it is appropriate to think of the non digital city digitally. Urban design is one state which establishes the perfect relationship between the street, people and building. The relationship of the people with the building and street is becoming one of the key factors in architecture. It has been observed that the design of a city has been influenced by the pedestrian movement. Many cities prior to the industrial era were largely determined by the social interactions based on walking. Thus the pedestrians play a key role in the formation of the city. They are a very important component in any representation of transport movements. They generally terminate or initiate a chain of linked activities, and if observed carefully, a single pedestrian movement is meant to include various sub journeys from one location to another. In order to organize pedestrians, we need to understand the pedestrian movement system. Though there is a lot of development of urban models in this aspect, it is still in a nascent state in comparison with the digital advancement. Thus much research work is carried out which can be applied to any given environmental setting, and as a result urban designers can respond to the changing socio-cultural technologies.

title	Computer Renderings – „Reality is Overrated”

doi	https://doi.org/10.52842/conf.ecaade.2005.729
summary	In this paper, two problems concerning truthfulness of computer-generated visualization are considered. The first one concerns relationships between reality and its representation by computer renderings. The second problem concerns the kind of representations people need. These problems are analyzed for static perception of architectural forms based on computer visualization, and for dynamic walk-through perception of urban space. The thesis of the paper is that many photorealistic renderings are excessively realistic and thus not true. In this context, a new question arises: do we need the true representation of an object? The author claims that we need “adequate” pictures. Adequate means a picture that is satisfactory in particular situation. The problem of equivalence of media (renderings and animations) and reality is not that important here. Much research is concerned with the truthfulness and falsity of information. However, they do not take into consideration that frequently what seems to be real exerts bigger influence on people than what is in fact real. Understanding this problem may help us in producing images that better correspond to people’s expectations.

title	A Representation Language for a Prototype CAD Tool for Intelligent Rooms
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 170-183
doi	https://doi.org/10.52842/conf.acadia.2005.170
summary	Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

summary	This article describes an analysis of the morphological changes between 2005 and 2020 in the Vila Cabral neighborhood, located on the outskirts of the Brazilian city of Campina Grande. The research was developed in two different analytical scenarios, adopting the algorithmic- parametric computational implementation as a methodology, and applying the following procedures: (i) formal decomposition of a sample of the urban fabric; (ii) visibility graph analysis (VGA); (iii) analysis of the diversity of uses and (iv) analysis of urban density (populational and built). The study demonstrated that the association of different urban analysis tools strengthens decision-making in the context of evidence-based urban design.

summary	Collaborative design activity that involves remote multilateral, multidisciplinary communication has become more commonplace with the electronic means to communicate across any distance in real time. The communication itself can be both an important repository of project information and an important part of the process of conceptualisation and design development. This research has explored the apparent shortcomings inherent in commonly used means of communication and how these impact on the design process. This paper describes research that has taken as a starting point the analysis and observation of actual design communication from the archive of an internationally published collaborative project involving disciplinarily diverse and globally scattered participants. Through the analysis, we have identified characteristics of communication tools or information environments that would address the particular issues found to impede collaboration while fostering those aspects that support it. The findings have been used to inform the design, specification and implementation of collaborative information spaces based on Wiki software.

title	Dynamical structural modeling A collaborative design exploration
source	International Journal of Architectural Computing vol. 3 - no. 1, 27-42
summary	This study is based on a generative performative modeling approach that engages architects and structural engineers in close dialogue. We focus on knowledge shared between engineers and architects to apply the Finite Element Analysis based structural design technique Evolutionary Structural Optimization [ESO] as a way to understand or corroborate the performance factors that are significant in determining architectural form. ESO is very close conceptually to the dynamical system of matter and forces of growth itself. It has parallels both mathematical and metaphorical with natural evolution and morphogenesis so it has been poignant to apply the approach to a formal architectural case study in which the generative influence of these processes is inherent.

title	From Bézier to NURBS: Integrating Material and Digital Techniques through a Plywood Shell
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 156-169

summary	The development of digital fabrication has reintroduced material processes with digital processes. There has been much discussion about the tool and the objects of the tool, but little discussion of the implication of the material process on the digital process. A brief historical review on the development of computer numerical control and the origins of the Bézier curve reveals an instrumental fact: computer numerical controlled tools necessitated advancements in computational surfaces which eventually led to NURBS (Non-Uniform Rational B-Splines) surfaces. In other words, the origins of NURBS surfaces resides in its relation to material processes, rather than many current approaches that develop free form surfaces and then force the tool onto the material without regard to the material properties. From this historical and mathematical review, this project develops toward more intelligent construction methods based on the integration of NURBS differential geometry paired with material qualities and processes. Specifically, a digital technique of developing conceptual NURBS geometry into piecewise surface patches are then flattened based on the material thickness and density. From these flattened patches, a material technique is developed to intelligently remove material to allow the rigid flat material to re-develop into physical surface patches. The goal of this research is to develop digital and material techniques toward intelligent construction based on the correspondence between digitally driven surface and digitally driven material processes. The application of this technique as a rational and flexible system is to support the dynamic response of form and material toward such performative aspects as structure, daylight, ventilation, and thermal properties.

title	Three-Dimensional Shape Generation of Low-Energy Architectural Solutions using Pareto Genetic Algorithms
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 647-654
doi	https://doi.org/10.52842/conf.ecaade.2005.647
summary	This paper extends on a previous work on the application of a Generative Design System [GDS] to the evolution, in a computational environment, of three-dimensional architectural solutions that are energy-efficient and adapted to the climatic environment where they are located. The GDS combines a well-known building energy simulation software [DOE2.1E] with search procedures based on Genetic Algorithms and on Pareto optimization techniques, successfully allowing to tackle complex multi-objective problems. In the experiments described, architectural solutions based on a simplified layout were generated in response to two often-conflicting requirements: improving the use of daylighting in the space, while controlling the amount of energy loss through the building fabric. The choice of a cold climate like Chicago provided an adequate framework for studying the role of these opposing forces in architectural form generation. Analysis of results shows that building characteristics that originate successful solutions extend further than the building envelope. Issues of massing, aspect ratio, surface-to-volume ratio, orientation, and others, emerge from the analysis of solutions generated by the GDS, playing a significant role in dictating whether a given architectural form will prove adapted to its climatic and energy requirements. Results suggest that the questions raised by the exploration of form generation driven by environmental concerns are complex, deserving the pursuit of further experiments, in order to better understand the interaction of variables that the evolutionary process congregates.
