summary There is limited research and discussion on pedagogical approaches in architectural education, simply because it is considered as one of the “unimportant” areas that researchers “do not bother studying” (Teymur, 2001). Problem Based Learning has been known to provide competent graduates in other professional disciplines, and, consequently, there have been attempts to utilise the same pedagogical approach in architectural education where PBL is seen as a potential solution to the problems encountered in architectural education. This paper critically reviews PBL implementations at TU Delft Netherlands and Newcastle University, N.S.W. Australia and draws conclusions with particular respect to the teaching of architectural computing

title The Digital Design Process: reflections on architectural design positions on complexity and CAAD
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 These instructions are intended to guide contributors to the Second Architecture is presently engaged in an impatient search for solutions to critical questions about the nature and the identity of the discipline, and digital technology is a key agent for prevailing innovations in architectural design. The problem of complexity underlies all design problems. With the advent of CAD however, Architect’s ability to truly represent complexity has increased considerably. Another source that provides information about dealing with complexity is architectural theory. As Rowe (1987) states, architectural theory constitutes “a corpus of principles that are agreed upon and therefore worthy of emulation”. Architectural theory often is a mixed reflection on the nature of architectural design, design processes, made in descriptive and prescriptive terms (see Kruft 1985). Complexity is obviously not a new issue in architectural theory. Since it is an inherent characteristic of design problems, it has been dealt with in many different ways throughout history. Contemporary architects incorporate the computer in their design process. They produce architecture that is generated by the use of particle systems, simulation software, animation software, but also the more standard modelling tools. The architects reflect on the impact of the computer in their theories, and display changes in style by using information modelling techniques that have become versatile enough to encompass the complexity of information in the architectural design process. In this way, architectural style and theory can provide directions to further develop CAD. Most notable is the acceptance of complexity as a given fact, not as a phenomenon to oppose in systems of organization, but as a structuring principle to begin with. No matter what information modelling paradigm is used, complex and huge amounts of information need to be processed by designers. A key aspect in the combination of CAD, complexity, and architectural design is the role of the design representation. The way the design is presented and perceived during the design process is instrumental to understanding the design task. More architects are trying to reformulate this working of the representation. The intention of this paper is to present and discuss the current state of the art in architectural design positions on complexity and CAAD, and to reflect in particular on the role of digital design representations in this discussion. We also try to investigate how complexity can be dealt with, by looking at architects, in particular their styles and theories. The way architects use digital media and graphic representations can be informative how units of information can be formed and used in the design process. A case study is a concrete architect’s design processes such as Peter Eisenman Rem Koolhaas, van Berkel, Lynn, and Franke gehry, who embrace complexity and make it a focus point in their design, Rather than viewing it as problematic issue, by using computer as an indispensable instrument in their approaches.

title Usage of Planning Support Systems - Combining three approaches
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 263-274
summary Although a wide range of Planning Support Systems (PSS) exists, their actual utilization in planning practice, to support planners in doing their planning tasks, stays behind. This is problematic since many see PSS capable of aiding planners to handle the complexity of their planning tasks. Our current study explains under usage of PSS from three different angles: the instrument, the user and the transfer of the instrument towards the user. The main conclusion is that usage of PSS is hampered by lack of awareness of and experience with PSS in planning practice as well as by instrumental quality problems and hampered user acceptance and diffusion. The main recommendation to enhance usage of PSS is that it should be made transparent which PSS types should be used for what planning tasks, by which kinds of users, in which kinds of organizations and under which external conditions.

title Linking Land Use Modelling and 3D Visualisation - A mission impossible?
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 85-101
summary Additional to the traditional land use maps 3D visualisation could provide valuable information for applications in the field of spatial planning, related to ecological and agricultural policy issues. Maps of future land use do not always reveal the appearance of the physical environment (the perceived landscape) as a result of land use changes. This means that 3D visualisations might shed light on other aspects of changed land use, such as expected differences in height or densities of new volume objects, or the compatibility of these changes with particular characteristics of the landscape or urban built environment. The Land Use Scanner model was applied for the Netherlands Environmental Assessment Agency's 'Sustainability Outlook' to explore land use changes, followed by GIS analyses to asses both the development of nature areas and the degree of urbanisation within protected national landscapes. Since it was felt that 3D visualisation could complement the resulting land use maps, the land use model output was coupled to 3D visualisation software in two different ways: 1) through Studio Max software in combination with iconic representation of the concerned land use types and 2) through 3D components of GIS software. However, the use of these techniques on a national scale level for the generation of semi-realistic 3D animations raised a number of conceptual and technical problems. These could be partly ascribed to the particular format and of the Land Use Scanner output. This paper discusses the methods and techniques which have been used to couple the output of the land use model to 3D software, the results of both approaches, and possible solutions for these problems.

title Communication in the Implementation of a Metacognitive Strategy for Learning to Design
source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 818-825
doi https://doi.org/10.52842/conf.ecaade.2006.818
summary This paper describes an instructional communication strategy that makes use of time-based media techniques (story boarding and animation) in order to empower design studios with means to promote their students’ awareness on the acquisition of metacognitive knowledge and skills. This paper highlights the importance of including the communication of the design processes in the evaluation of learning outcomes. Moreover, the paper proposes that the students should be made constantly aware of their design processes and how effective are the methods they use. It is in this state of awareness that metacognitive knowledge is acquired: knowing how to learn to design. We can cultivate, exploit and enhance the capabilities of design learners, making them more confident and independent as learners as they understand what they need to know and what kind of strategies might work for different design problems and learning opportunities. In the development of an instructional strategy to accomplish this learning goal, the paper proposes it may be possible and potentially beneficial to transfer current metacognitive support strategies from a course on computer visualization techniques to the design studios. The paper elaborates on how these communication strategies could be transferred and implemented in a design studio setting. The results of a recent controlled experiment and considerations about the cognitive style of design students will be used in the preparation of recommendations for future full scale implementations in early design studios.

summary Context awareness is important for human senses of places as well as human computer interaction. The aim of this research paper is focusing on controlling the user's privacy in a smart space which is adaptive to different users for enhancing the user's awareness in his diary life. In Environmental Psychology, the definition of privacy is that an individual has the control of deciding what information of himself is released to others, and under how he interact with others. (Westin 1970) And privacy is categorized as the linguistic privacy and visual privacy. (Sundstorm 1986). Solutions for privacy control: Plan Layout, Vision Boundary, Access Control and Architecture Metaphor - the transmission of information is not ascertainable for every single user. Although information are shown in public, but information is implied by cues and symbols. Only a certain user or a group of users have access to the full context of information. The methodology is to form an analytic framework to study the relationship between information, user and activities by using the computational supports derived from KitchenSense, ConceptNet, Python, 3d Studio Max and Flash; and to record patterns built up by users' behaviour and actions. Furthermore, the scenario-based simulation can envision the real world conditions by adding interfaces for enhancing user awareness.

title A Constraint-Based Building Bulk Design Support
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
summary We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 346-349
summary This article approaches the social use of digital immersive environments in two different realms. One aiming at the digital training of self-builders involved in participatory design of affordable housing and the other dealing with experimental connection of lowincome communities (favelas) placed at different geographic locations. It first describes the specific digital immersive environment called Digital TENT, developed at IBPA/LAGEAR, which aims to investigate the production of space by means of bodily engagement with images within the perspective of the experience rather than that of the spectacle. Subsequently, it discusses the conceptual basis of the TENT (Technological Environment for Negotiated Topology) as opposed to the CAVE (Cave Automatic Virtual Environment), This discussion is deepened into a critique of the visual representation of space opposed to the possibility of dynamic creation of environments that only happen in present time with peoples' interaction, Such a critique, associated with two social experiences carried out by IBPA/ LAGEAR, leads to the conclusion that the Digital TENT is effective for both supporting visualization processes and spatial negotiation in participatory design, and also as a place for enhancing the very experience.

title Generation of alternative designs in architectural problems using Shape Grammars defined with animation tools - A computer implementation of shape grammars using modelling and animation software

summary We present a model of generation of alternative designs to selected architectural and spatial configurations of small complexity. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of time and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. The alternative designs vary from the original according to their temporal and/or spatial distance from the original object on the animation time-line. The constraints placed upon the objects , used as actuators of Shape Grammars, are defined informally by the user/designer while their influence can vary according to time, speed, location, configuration of the object and/or the constraint itself. However the constraints further function as formal rules for the Shape Grammar creation so that our model tries to predict ahead of time the emergence of alternate designs. The employ of animation tools [shape driven curves, speed and time-line functions,parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established: either the animated schema may be a sum or family of various designs or the animated time-line represents a single design which changes over time. Finally the possibility of an automated analysis of every design is discussed, using Space Syntax diagrams so the designer can quickly evaluate the various spatial configurations produced by a single original.

title Evolving Urban Structures using Computational Optimisation
source Proceedings of the Generative Arts conference, Milan, 2006
summary This paper investigates the use of computer analogies for naturally inspired optimisation techniques as an aid to developing the site layout and massing for the new World Trade Centre development in Pristina Kosovo, which is being designed and developed by 4M Group architectural company, in conjunction with the Advanced Modelling Group Aedas. The development of a genetic algorithm will incorporate various techniques, that have been developed in the field of multi-objective optimisation, to create three dimensional massing models, and site layout solutions which partially fulfil the Prisina brief requirements, which are taken from specifications created by 4M Group. Genetic algorithms are based on natural evolutionary principles which are explained in this paper. It will incorporate Pareto concepts to manage the optimisation of the various objective functions. For example, these will include volume and position of units, which will ensure that the different and sometime conflicting needs of the site are balanced throughout the optimisation. This type of problem is often known as an NP-complete (non-determinate polynomial time) problem. This will provide architects and planners with a number of Pareto optimised site massing solutions as an aid to the design process. An initial investigation into the specifics of the Pristina site requirements, will be followed by an investigation into the the genetic algorithm which is created in Visual Basic for Applications (VBA) linked with AutoCAD as the graphical output of the code. The embryology (development) of the various solutions from the genetic information incorporates an ‘ant’ pheromone trail model, which simulates the action of ants during food foraging, as a tool for initial route planning within the site. Diffusion and cellular automata are used during the development of the solution to construct the massing for the site.

summary This research studies the relationship between architectural language and thought, using digital models to communicate architectural concepts. It studies in particular two renowned buildings of contemporary architecture in Chile. A tower for insurance company in the downtown of the city of Concepcion, designed by architect Enrique Browne, well- known by his ecological approach. And offices for industry of timber boards close to the city of Arauco, designed by architect Jose Cruz Ovalle, whom applied sensitive background. Digital models of both buildings were developed to show different characteristic and parts. A group of students evaluate semantic interpretation of these digital models, when other evaluates same conditions with pictures of the buildings. The results showed high understanding of language, but low appreciation of meaning and thoughts, close to general values than particular approaches, supporting basic architectural concepts and use of diverse digital models.

title A framework towards designing responsive public information systems

summary "Evolving effective responsive systems, and creating a credible interface between the work and the user, requires an awareness of many different types of user, contexts and functions as well as the phenomenological aspects of social and environmental conditions." (Bullivant, 2006). Responsive design and interactive architecture operates at the intersection of Architecture, Arts, Technology, Media Arts, HCI and Interaction Design in a physical context suggesting ways in which the existing physical environments can be augmented and extended adding a greater level of depth, meaning and engagement with the world around us. Through a series of case studies, this paper explores a number of principles which may be applied to the design of responsive environments of which public information systems form part. Divided into three main sections, the paper first explains how responsive environments have addressed the application of public information systems, secondly, through a series of case studies, precedents are highlighted which lead to development of principles for developing designs for responsive environments. The third section discusses and elaborates on these principles which have been developed based upon our own interpretations and grouping of precedents and approaches towards interaction design. This paper contributes towards the field of responsive environments and interactive architecture through an analysis of case studies to infer a framework from which responsive environments may be created and developed.

title Computational Design of Parametric Scripts for Digital Fabrication of Curved Structures
source International Journal of Architectural Computing vol. 4 - no. 3, 99-117
summary This paper explores strategies for building toolchains to design, develop and fabricate architectural designs. It explains how complex curved structures can be constructed from flat standard panels. The hypothesis of this research is that by embedding ruled based procedures addressing generative, variational, iterative, and fabricational logics into early phases of design, both design techniques and digital fabrication methods can merge to solve a recurrent problem in contemporary architectural design, building double curved structures. Furthermore it achieves this using common fabrication methods and standard construction materials. It describes the processes of programming computational tools creating and developing designs to fabricate continuous complex curved structures. I describe this through a series of experiments, using parametric design environments and scripted functions, implementing certain techniques to fabricate these designs using rapid prototyping machines. Comparing different design and fabrication approaches I offer a discussion about universal application of programmed procedures into architectural design.

title Foundations for a Constraint-Based Floor Plan Layout Support in Participatory Planning of Low-Income Housing
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 283-287
summary We introduce the foundations of a novel approach that deals with constraint-based design methods to supporting participatory planning processes of low-income dwellings. We examine the space allocation problem inside the architectural domain on the basis of graph theory and combinatorics, providing a concise mathematical background for an implementation strategy called FLS (Floor plan Layout Support), which is analyzed here for the first time regarding this particular context of application. The philosophy underlying a design method that is mainly driven by the formulation of distinct constraints suggests to avoid the traditional procedure of first to create a yet not necessarily valid instance of the eventual design solution by directly choosing specific parameter values of its shape, and later on to evaluate its validity by confronting the designed model to a set of applicable constraints. Instead, constraint-based design poses a search procedure that operates in a space of planning-relevant constraint sets. The FLS methodology integrates some few principles of constraint-based automated reasoning with high user interactivity, into a design environment where as much dwellers as planners can collaboratively work in solving spatial organization problems of housing projects. The FLS model of application makes use of a combination of dweller-specified constraints, planning and zoning regulations, and a small library of modular space units. Constraint-based design ! methods are particularly capable of supplying efficient support for the collaborative involvement of dwellers into the architectural programming process of her/his own home. Mainly, because dwellers themselves tend to describe their space need and design intentions as a set of constraints on room quantity, space utilization, circulation system, allocation of available furniture, available budget, construction time, and so forth. The goal is to achieve an integrated tool for finding and modelling topologically valid solutions for floor plan layout alternatives, by combining user-driven interactive procedures with automatic search and generative processes. Thus, several design alternatives can be explored in less time and with less effort than using mainstream procedures of architectural practice. A FLS implementation will constitute one system module of a larger integrated system model called Esther. A FLS tool shall interact with other functional modules, like e.g. the BDS (Building Bulk Design Support), which also uses constraint-based design methods. A preliminary procedural model for the FLS was tested on Chile’s official social housing standards (Chilean Building Code – OGUC. Art. 6.4.1) which are very similar to most Latin American housing programs currently in operation.

title Road hierarchy and speed limits in Brasília/Brazil

summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title FULL 3D STRUCTURAL ZONING OF SPACE: Using a Geometrically Related Reducer and Matrix Coupling

summary Structural zoning is the recognition of forms in spatial designs. It can be used by a structural designer to develop a structural system. This paper will start with the presentation of a proof that neither user action nor a two-dimensional approach -two existing approaches of zoning- are able to recognize all possibilities for the application of a structural design to a spatial design. Only full three-dimensional structural zoning is considered to be an appropriate instrument to give useful solutions. Two new concepts will be presented to overcome problems for three-dimensional zoning: (1) Geometrically Related Reducers and (2) Matrix Coupling. These concepts are first defined in a general form and thereafter the definitions are condensed into a practically applicable format. Both concepts are demonstrated when finding rectangular zones in spatial designs up to 44 separate spatial entities. They are programmed procedurally using the C++ computer language and are used for a comparison between structural designers and computer performance.

title An Approach to 3D Conceptual Modelling
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 This article presents a 3D user interface required by the development of conceptual modeling. This 3D user interface provides a new structure for solving the problems of difficult interface operations and complicated commands due to the application of CAD 2D interface for controlling 3D environment. The 3D user interface integrates the controlling actions of “seeing – moving –seeing” while designers are operating CAD (Schön and Wiggins, 1992). Simple gestures are used to control the operations instead. The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis. The study aims to discuss the provision of more intuitively interactive control through CAD so as to fulfil the needs of designers. In our practices and experiments, a pair of LED gloves equipped with two CCD cameras for capturing is used to sense the motions of hands and positions in 3D. In addition, circuit design is applied to convert the motions of hands including selecting, browsing, zoom in / zoom out and rotating to LED switches in different colours so as to identify images.

title The Art of Communication: a Collaborative Decision-Making System among Different Industrial Design Stakeholders - The case of the company ASUS
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 271-288
summary Collaboration benefits the process of complex design. However, there are many communication problems among different stakeholders in the domain of industrial design, because the situation of communication and decision-makings for stakeholders is so complicated. To deal with the complexity requires both a web-based collaborative system to communicate and share information immediately, and a multi-agent system (MAS) integrated with KW architecture to possess different levels of competence at performing a particular task. The goal of our system is to integrate a variety of representational methods of transferring knowledge and to communicate among different stakeholders using a single platform. To demonstrate our proposed concepts, we focus on a prototype system for notebook design for the company ASUS, a leading notebook manufacturer based in Taiwan.

title STRONG VALID INEQUALITY CONSTRAINTS FOR ARCHITECTURAL LAYOUT DESIGN OPTIMIZATION

summary In the past decades, many attempts have been made to solve the challenging architectural layout design problem such as non-linear programming and evolutionary algorithm (Michalek and Papalambros, 2002). The Mixed Integer Programming (MIP) (Kamol and Krung, 2005) was recently developed to find the global optimal solution. However, the problem can be shown to belong to the class of NP-hard problem (Michalek and Papalambros, 2002). Hence, only the small instances of the problem can be solved in a reasonable time. In order to deal with large problem sizes, this paper utilizes the strong valid inequalities (George and Laurence). It cut off the infeasible points in the integral search space by formulated the disconnected constraints involved with line configurations of three rooms. It is shown to significantly increase the computational speed to more than thirty percents. This exhibits the practical use of the MIP formulation to solve the medium size architectural layout design problems.
