title	Strategic Briefing A Conceptual Process Model for Building Design
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Nowadays building design problems are divided in partial discipline related sub-problems. Through targeted and focused attention to sub problems however the awareness of the whole is lost. Each designparticipant gives his sub-problem first priority. In contrast in the past the master builder saw the whole problem as his problem first. Thus the process of seeing the design problem as a whole, as a result ofprioritizing, considering constraints, or strategizing, is lost in today’s practice, basically because this process is a mental and implicit process, that occurred in the brain of the multi-disciplinary master builder.In most cases it is the task of no one in a design team today. The aim of this paper is modeling this conceptual mental implicit process design using System Theory and Cognitive Psychology, trying to determine the structure of the design problem as it occurs intuitively in the brain. The result will provide us with a mechanism that enables us each time to refine a unique common design problem representation. This leads to more effective use of design team capabilities, and forms an essential basis for organizing efforts toward collaborative solutions. Also some kind of clarity is provided as to how proposed solutions are to be judged.

title	Modelación de Actividades [Modeling of Activities]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 151-154
summary	Despite increasing interest in the functionality and humanization of architecture, scarcely the occupation of buildings are studied and it lacks methods to represent activities in the spaces. By this reason, it proposes a system such integrates simulation of processes and virtual modeling software, to program the behavior of tri-dimensional characters based on the probabilistic evolution of events, testing this approach in the study of emergency services of hospitals. It describes the procedure developed and reflections about temporal representation, demonstrating that modeling of activities allows to suggest functional and spatial improvements.

title	An Innovative Model of the Building Development ProcessDesign as a Process of Crystallisation
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	In the past, models describing the development of artefacts, including buildings, usually were of a linear nature thereby suggesting a sequential path from conception of the artefact to its completion. This has consequences for the sequence of activities in the design and programming phase. However, designing is basically a thinking activity and is as such not bound to the same laws as e.g. the construction process. This must have repercussions for the way the design process is designed andmanaged. The proposed conceptual model of the artefact development process – in this case a building design process – is a kind of framework which is more in accordance with the nature of thinkingactivities. It should stimulate a non-sequential process. The development of a solution to a design problem thus should become a responsive search process driven by insights and creative leaps but guided by the framework the model provides. Furthermore, the model is meant to support the exploration and clarification of the problem as well as to extend the solution space by various means such as the development of scenarios and strategic values as a basis for the realisation of the building project’s goals. This model is an essential element in the development of an innovative approach towards the process design of the building design process. The creation of a building (conception, design and development) is not considered a sequential process but a process of crystallisation with the potential of developing in all directions, thus growing from a conceptual centre outwards.

title	Interdisciplinarity: Perceptions of the Value of Computer Supported Collaborative Work in Design for the Built Environment
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 221-228
doi	https://doi.org/10.52842/conf.caadria.2002.221
summary	This paper presents the findings from a study into the current exploitation of CSCW in design for the built environment in the UK. The research is based on responses to a web-based questionnaire. Members of various professions including civil engineers, architects, building services engineers and quantity surveyors were invited to complete the questionnaire. The responses reveal important trends in the breadth and size of project teams at the same time as new pressures are emerging regarding team integration and efficiency. The findings suggest that while CSCW systems may improve project management (e.g. via project documentation) and the exchange of information between team members it has yet to significantly support those activities that characterize integrated collaborative working between disparate specialists. The authors conclude by combining the findings with a wider discussion of the application of CSCW to design activity – appealing for CSCW to go beyond multidisciplinary working to achieve interdisciplinary working.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	Semi-metric formal 3D reconstruction from perspective sketches
source	Proceedings of International Conference on Computational Science (ICCS), pp. 285-294, Amsterdam, The Netherlands
summary	We present a new approach for accurate and fast reconstruction of 3D models from hand-drawn perspective sketches and imposed geometric constraints. A distinctive feature of the approach is the decomposition of the reconstruction process into the stages of correction of the 2D sketch and elevation of the 3D model. All 3D constraints that describe the spatial structure of the model are strictly satisfied, while preferences that describe the model projection are treated in relaxed manner. The constraints are subdivided into the projective, affine and metric ones and expressed in algebraic form by using the Grassmann-Cayley algebra. The constraints are resolved one by another following the order of their types by using the local propagation methods. The preferences allow to apply linear approximations and to systematically use formal methods.

title	Space-related Content-Management
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 400-403
doi	https://doi.org/10.52842/conf.ecaade.2002.400
summary	Establishing virtual city models (“digital cities“) has become an important planning tool for configuring the future of our cities and vital spaces. The present contribution discusses the concept of “Space-related Content-Management” and its interlaceable possibilities of implementation in the planning and configuration process. The activities of those acting in space and their impacts on space, e.g. leading to new, additional and renovation of buildings, to the demolition of buildings, to alterations regarding vegetation stock, traffic infrastructure, etc., do not result from a static conception of physical space, but exclusively suggest a dynamic one. Real space is subject to continuous changes. The constant changing of physical space thus represents a considerable factor concerning the conception of the virtual image (virtual city model). The dynamics of space suggests the development of “data-pipelines“ as core elements of virtual city models. Only this pipeline-concept can account for the dynamics of space. It is suggested to embed “datapipelines“ in “Content-Management-Systems (CMS)“ thus promoting the concept of “Space-related Content-Management“ including all kinds of space-related information enriched with metainformation that might be useful during the planning- and configuration process. “Space-related Content-Management-Systems (SCMS)“ are considered as navigation systems through complex space-related data sets supporting a broad range of questions during the planning- and configuration process. The application fields of “Space-related Content Management-Systems“ are supposed to integrate the complete planning process starting with the space-related analysis and model generation via characterization of space and winds up at the development of space-related concepts to be passed on to those involved in the space under consideration.

title	Interactive Storytelling and Its Role in the Design Process
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 151-158
doi	https://doi.org/10.52842/conf.caadria.2002.151
summary	Projects of ever increasing complexity and size have incited the need for new and robust design methodologies and tools in an effort to manage complexity, lower costs, ascertain quality and reduce risk. Technology convergence through the growing availability of networked computers, rapid progress in Computer Aided Design (CAD) and information management have encouraged the undertaking of even more complex designs that demand high degrees of interaction, collaboration and the efficient sharing and dissemination of information. It is suggested that interactive storytelling and interactive design (Rafi and Karboulonis, 2001) techniques that use non-linear information mapping systems can be deployed to assist users as they navigate information that is structured to address localized needs as they arise. The design process is a collaborative effort that encompasses diverse knowledge disciplines and demands the management and utilization of available resources to satisfy the needs of a single or set of goals. It is thought that building industry specialists should work close together in an organised manner to solve design problems as they emerge and find alternatives when designs fall short. The design process involves the processing of dynamic and complex information, that can be anything from the amount of soil required to level lands - to the needs of specific lightings systems in operation theatres. Other important factors that affect the design process are related to costs and deadlines. This paper will demonstrate some of our early findings in several experiments to establish nonlinear storytelling. It will conclude with a recommendation for a plausible design of such a system based on experimental work that is currently being conducted and is reaching its final stages. The paper will lay the foundations of a possible path to implementation based on the concept of multi-path animation that is appropriate for structuring the design process as used in the building industry.

summary	Evolution of trends in the realm of computer aided architectural design (CAAD) has seen the convergence of technologies – complementing traditional tools with emerging sciences like Information Technology (IT) and multimedia applications. This appliqué of technologies has not just expanded the scope and enhanced the realm of CAAD research and practice, but is also breaking new frontiers. This creative nexus will be realised at the 7th International Conference on Computer Aided Architectural Design Research In Asia (CAADRIA 2002) to be held at the Faculty of Creative Multimedia, Multimedia University, Malaysia, between 18th-20th April, 2002. CAADRIA 2002’s theme, "Redefining Content", seeks to recognise and infuse these emerging components in the field of architecture and design with a holistic approach towards online, digital and interactive systems. The 41 papers compiled were selected through a blind review process conducted by an international review panel. To reflect the multi-disciplinary nature of this year's conference, the chapters are arranged topically to facilitate the in-depth study of key components. The component sessions include: // Web Design, Database and Networks // CAD, Modelling and Tools // Collaborative Design, Creative Design and Case Reasoning // Simulation and Prototyping // Virtual Environment and Knowledge Management // Design Education, Teaching and Learning /// We believe that this specialised approach will provide a deeper and more illuminating feel of the various components and their critical convergence in the field of architecture and design.

title	Urban Sprawl Modelling: Combining Models to Make Decision
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	Urban sprawl is frequently associated with the idea of an unsuitable development, leading to increasing economic, social and environmental problems. Moreover, its control is difficult because multiple patterns (concerning numerous traditional urban planning fields) overlap. In order to understand the sprawl process and to manage its consequences, it must be simplified. The construction of a decision making tool appears then interesting. The GIS-based tool presented here is being developed incollaboration between the urban planning agency of Belfort and the laboratory of geography of Strasbourg. It requires three steps: 1. quantification of the sprawl (how much areas are involved in theurban sprawl process?); 2. location of the sprawl (where are the areas defined in the first step?); 3. differentiation of the sprawl (what are the areas located in the second step?). Of course, the successionof the three stages makes the use of the complete model more complex. So, a global ergonomic user interface is being developed within the GIS, allowing to modify each parameter and to play easily numerous simulations.

doi	https://doi.org/10.52842/conf.acadia.2007.174
summary	This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

title	Digital Design - Research and Practice
source	Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1 / Tainan (Taiwan) 13–15 October 2003, 464 p.
summary	The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title	The Glass Chair - Competence Building for Innovation
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 180-185

summary	This paper tells the strange tale of a glass chair. Creating a glass chair might seem a perverse – maybe impossible – enterprise. After all, chairs are normally held together by moment connections, such as those joining the legs to the seat. Glass is a notoriously bad material for forming moment connections; it is brittle, and quickly snaps if you subject it to bending. But there are advantages to such startling formulations of design problems. They force you to challenge conventional wisdom, to ignore standard prototypes, and to ask interesting new questions. How might you design a chair without moment connections? How might you do so without making the result impossibly heavy? How would you built it? And what interesting qualities might such a chair have? These were questions investigated in the design project pursued jointly by students at an American and a Portuguese school, in collaboration with glass and molding fabricators. The students explored many possibilities, and in doing so learned a great deal about chairs and about the properties and potentials of glass. The final project is a particularly elegant outcome of their investigations. It is created from just two curved pieces of glass, which held together by metal tie-rods. In the end, the finished glass chair looked just like the initial computer visualizations.

title	Interacting unities: an agent-based system
source	International Conference on Generative Art
summary	Recently architects have been inspired by Thompson’s Cartesian deformations and Waddington’s flexible topological surface to work within a dynamic field characterized by forces. In this more active space of interactions, movement is the medium through which form evolves. This paper explores the interaction between pedestrians and their environment by regarding it as a process occurring between the two. It is hypothesized that the recurrent interaction between pedestrians and environment can lead to a structural coupling between those elements. Every time a change occurs in each one of them, as an expression of its own structural dynamics, it triggers changes to the other one. An agent-based system has been developed in order to explore that interaction, where the two interacting elements, agents (pedestrians) and environment, are autonomous units with a set of internal rules. The result is a landscape where each agent locally modifies its environment that in turn affects its movement, while the other agents respond to the new environment at a later time, indicating that the phenomenon of stigmergy is possible to take place among interactions with human analogy. It is found that it is the environment’s internal rules that determine the nature and extent of change.

title	Generative and Evolutionary Techniques for Building Envelope Design
source	International Conference on Generative Art
summary	The authors have been involved in the use of generative techniques for building envelope design since 1968 and the use of genetic algorithms since 1990. Recent work has focused on incorporating optimisation functions into form generating processes in order for new forms responding to varied design environments to be created and determined. This paper will summarise the authors’ previous work in this field and explain the theory behind this approach, and illustrate recent developments. While the initial implementation of a new building envelope design system is reported in more details in a related paper at this conference, this paper outlines its main features and points out the direction at which it is to be fully developed and further improved.

title	Modular Perspective as a Method for Generative Design
source	International Conference on Generative Art
summary	Apparently there are many methods for perspective but if we categorize them there are just a few. Some criterions of classification relate perspective to the so-called 1-point, 2-point and 3-point methods, others —more formally— to projective geometry, descriptive geometry or vectorial algebra. Of course we cannot forget to mention the early treatises on perspective such as Alberti’s Della Pittura or Piero’s De Prospectiva Pingendi, which escapes any classification. Our aim on this article is not precisely to solve the classification problem rather we propose a new comprehensive method for perspective, capable of 3D representation without using vanishing points.The modular perspective method allows us to work in true three-dimensionality on the perspective plane (PPl). We will explain how to measure directly on the PPl the triad coordinates (x, y, p) of a given point into the visual space, and how to play with the symmetrical planes X and Y (SPl X/Y) in order to generate or recover data. Finally we will explain how to employ modular perspective in generative design formal-process through an example of application.
