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	Distributed Agents for Morphologic and Behavioral Expression in Cellular Design Systems
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 111-121
doi	https://doi.org/10.52842/conf.acadia.2002.111
summary	After more than a century of domination by neo-Darwinian theory, biological thought is beginning to giveincreasing recognition to developmental theory. Amongst other reasons, this recent widening ofperspective is grounded on the incompleteness of the neo-Darwinian perspective in providing modelsfor the invention of novel forms or species and individual development. Evolutionary design theory hasdrawn much of its inspiration from evolutionary biology and consequently shows analogous flaws. Thispaper demonstrates an adoption of biological developmental theory to the field of design theory in orderto fill the corresponding gap. As natural developmental processes are based on the development ofcellular units, which form composite structures, this paper employs the cellular model as a means for thedevelopment of a corresponding design and construction theory. The discussion of this approachincludes possible linkages between morphologic and behavioral attributes of tissues with implicationsfor self-assembly, growth, healing and self-reproduction of man-made structures.

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	A design optimization tool based on a genetic algorithm
source	Automation in Construction 11 (2) (2002) pp. 173-184
summary	Much interest has been recently devoted to generative processes in design. Advances in computational tools for design applications, coupled with techniques from the field of artificial intelligence, have lead to new possibilities in the way computers can inform and actively interact with the design process.In this paper, we use the concepts of generative and goal-oriented design to propose a computer tool that can help the designer to generate and evaluate certain aspects of a solution towards an optimized behavior of the final configuration. This work focuses mostly on those aspects related to the environmental performance of buildings.Genetic Algorithms (GAs) are applied as a generative and search procedure to look for optimized design solutions in terms of thermal and lighting performance in a building. The GA is first used to generate possible design solutions, which are then evaluated in terms of lighting and thermal behavior using a detailed thermal analysis program (DOE2.1E). The results from the simulations are subsequently used to further guide the GA search towards finding low-energy solutions to the problem under study. Solutions can be visualized using an AutoLisp routine.The specific problem addressed in this study is the placing and sizing of windows in an office building. The same method is applicable to a wide range of design problems like the choice of construction materials, design of shading elements, or sizing of lighting and mechanical systems for buildings.

title	Generative Architectural Design and Complexity Theory
source	International Conference on Generative Art
summary	During the past decades, complexity theory has evolved as a new discipline that provides a broad scientific perspective towards dynamic real-life phenomena, challenging the classical linear worldview as well as simple cause-and-effect-style Newtonian physics. For architects, the advent of this new science offers the challenge as well as the chance to reconsider common design approaches and to invent new strategies based on the new paradigms. The actual application of complexity theory to architectural design, however, results in a fundamental dilemma: How can a reflective, ultimately retrospective body of thought (complexity theory) be applied to prospective design challenges (architecture)? Being part of a current MArch thesis project, the proposed paper focuses on this general dilemma between architectural design and complexity theory and discusses actual as well as potential future generative architectural design approaches involving complexity theory. Generative design strategies commonly apply algorithmic methods and formalisms, which can conveniently produce and deal with high levels of complexity. Complexity describes general properties of a system and can be further dissected into several modes: epistemic, ontological and functional complexity. This taxonomy offers insights into generative design applications, which have mostly focused on a limited set of complexity modes. Besides complexity generated by sheer numbers, aspects like functional or hierarchical complexity offer further perspectives on generative systems, processes and output. Considering these aspects of complexity theory, future challenges to generative architectural design can be predicted.

title	Using Social Interaction in Generative Design of Shared Virtual Spaces
source	International Conference on Generative Art
summary	The proposed paper outlines research findings in the field of generative design of visual virtual chat spaces. It discusses social interaction as a central determining factor in the generation of virtual spaces through and for chat communication on the World Wide Web. Social interaction in a chat room is based on communication using written text. The research and design results of this project involve the translation of chat statements into three-dimensional virtual objects according to - criteria derived from theories of virtual and social space, - the production of space through action and interaction of the users of the interface and - the translation of the components of written text (words and characters) into three-dimensional virtual forms. The generation of a dynamic, virtual, social structure is based on criteria deduced from systems of interaction within social space. The visual social structure, reflected in the shape and spatial relation of the three-dimensional objects, evolves as source for feedback processes and therefore as “re-generation” of social interaction. This paper documents the design, implementation and evaluation of the described system. It represents an outset and a first manifestation of a new project in cultural-differentiated user-interaction-centred generative approaches in interface design of chat room applications.

title	Models of Design Requirement
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Case studies show that significant proportions of design errors and failures are linked to poor requirement specification during both early stages of design and as changes occur. Computational requirements engineering as a front-end to design iterations is a promising area addressing theseproblems. In other design disciplines, such as in software engineering, requirement engineering has given significant product improvements. In this paper, we present a state-space representation of requirement models for architectural design. The purpose of requirement modeling in design is tocreate a process by which requirements can be converted into working design solutions through frontend validation. We suggest three models of requirement specification, co-evolutionary [CoM], multiple domain [MDM] and single domain [SDM] models, that can facilitate this effort. Taken together all three models provide a full set of logical permutations of requirement-solution “worlds” and “operations.” We compare each model against the others in terms of facilitating change management and computability.

title	Design devices: digital drawing and the pursuit of difference
source	Design Studies 23 (3) (2002) pp. 263-286
summary	We examine the uses of a prototypic device, in research and in design, for incorporating manual sketching into computer environments. We move from empirical and evolutionary conceptions of the role of such devices to the phenomenology of disclosure, attending to the revealing, generative, catalytic, metaphoric, signalling and provocative characteristics introduced by such devices. The discussion takes us through a series of steps that each amplifies the role of philosophical concepts of negation and difference in understanding the device.

title	CyberQuest Prospector (CQP):A Guide for the Evolutionary Discovery Process
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	CyberQuest Prospector (CQP) is a tool to guide an individual or team through the evolutionary process of finding better approaches to a particular problem, project, program, plan, or design. This prospectingprocess can involve, for example, new definitions, different data, altered evaluation techniques and new ideas and actions on many other topics. CQP involves a five step process. At step zero all the requisite historical background knowledge is entered. This knowledge is divided into topical areas or statements. In step one the team updates the various knowledge statements in the system and then assigns a "maturity" to them. The team then adds any new statements (step two). Next, (step three) the team makes decisions on actions to be undertaken and also on the external factors likely to be "in play" in the upcoming time period. After that period (step four) the team records the results and rates the "success" achieved. CQP subsequently changes the associated knowledge statement confidences. In the last step the clock is advanced. The ultimate result is a set of definitions, data, relationships, experimental techniques, issues,implications, and even personality traits in which some degree of confidence has evolved. The CQP process is demonstrated here with an urban transportation planning example involving such diverse topics asplanning/analysis techniques, data collection methods, and procedures for working with advocacy coalition networks.

title	A generative design system based on evolutionary and mathematical functions
source	International Conference on Generative Art
summary	Previous work by Professor John Frazer on Evolutionary Architecture provides a basis for the development of a system evolving architectural envelopes in a generic and abstract manner. Recent research by the authors has focused on the implementation of a virtual environment for the automatic generation and exploration of complex forms and architectural envelopes based on solid modelling techniques and the integration of evolutionary algorithms, enhanced computational and mathematical models. Abstract data types are introduced for genotypes in a genetic algorithm order to develop complex models using generative and evolutionary computing techniques. Multi-objective optimisation techniques are employed for defining the fitness function in the evaluation process.

title	The Evolving Role of the Artist
source	International Conference on Generative Art
summary	For more than a decade the author has designed and used algorithmic systems to produce artworks that incorporate generative and evolutionary concepts, forms and processes. This work has demonstrated that algorithmic aesthetic processes and products can be effectively created and modulated by both human beings and non-human systems. However, this work has also raised important questions such as: - What role can the individual human artist play in a cultural economy based upon industrialized generative processes and non-human systems? - How can artists integrate standardized scientific languages and algorithmic processes into personal visions and expressive languages? - How can artists capture their personal creative processes and encapsulate these processes in industry standard systems and software; and should they do so? - How might the generative systems and products created by human and non-human artists function and evolve in the larger social context? To address these questions, in this paper the author uses examples taken from his past and present artwork to illustrate the opportunities and pitfalls presented by computerized generative aesthetic processes and tools. In addition, the author offers a set of conjectures intended to help clarify issues such as: the evolving role of the artist as a producer of knowledge and form, and the value and appropriate structure of personalized computer languages for artists.

title	USING EVOLUTIONARY ALGORITHMS TO AID DESIGNERS OF ARCHITECTURAL STRUCTURES
source	Creative evolutionary systems, eds Bentley, Peter & Corne, David, Morgan Kaufmann, pp 315-336
summary	This paper describes the application of an Intelligent Genetic Design Tool (IGDT) in the design of architectural, structural elements. As a computer design aid an IGDT is innovative in its intelligent interaction with the designer. By always submitting multiple solutions for review by the designer, it is less likely to cause design fixation than other optimization techniques, and allows the user greater range in exploring hard-to-code design criteria such as aesthetics. As an example, the design of a cantilever truss is briefly explored. Using the coded optimization criterion of weight, and the designer's non-coded criteria of visual aesthetics and performance, a series of possible designs are explored. The ability of an IGDT to intelligently respond to the designer's preferences in a way that promotes creative thinking on the part of the designer is demonstrated. A final truss design is selected based on the use of the tool. It is concluded that an IGDT offers a significantly different approach to computer aided structural design which has the potential to enhance the user's own creativity in determining a good solution.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 186-189
summary	A Hypermedia system is, morphologically speaking, an information structure which organizes a set of elements of alphanumeric and graphic nature as a web. This enables a multidimensional access from specific interests. One of the most widespread hypermedia applications is within the field of education. There should be validation criteria which contribute to systematize and direct design processes for didactic hypermedia. This work aims at becoming a contribution by analyzing the relations and effects produced by the number of links and node sizes on some basic didactic uses; particularly, within information search, learning and attitude towards hypermedia. From the results obtained, we propose guidelines for the design of didactic Web Sites and CD Rom.

title	Design space navigation in generative design systems
source	Automation in Construction 11 (1) (2002) pp. 1-22
summary	Generative design systems make it easier for designers to generate and explore design alternatives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed if designers wish to access the information they generate with ease. We present a comprehensive approach to support information navigation in requirement-driven generative design systems, which gain their power form explicit representations of design requirements, which in turn add to the information generated by the system. Our approach takes into account studies dealing with human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. We structure the information to be accessed in terms of a five-dimensional design space model that applies across generative design systems of the type considered here. The model structure supports basic generic navigation operations along its five dimensions. We validated the model in the context of the SEED-Layout system and used it to extend the built-in navigation tools of the system through novel ones, which we subjected to a limited usability study. The study suggests that these tools have promise and warrant further investigation.

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	A Bottom-Up Approach to Design Coordination
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	The design industry like any other industry could benefit from process support for its practitioners. However, what constitutes legitimate process support for designers is a difficult research question. In order to support designers in their processes, first one needs to know what designers do. This is not only a question of knowing what designers do in general, but also what particular designers do in their own individual design practice. How to find out what designers do, that is, how to acquire knowledge abouttheir design processes, is also a difficult research question. Providing process support for designers is seen as a task, which cannot be divorced from design process acquisition. That is, one is unlikely to provideprocess support, without acquiring an understanding, what individual designers actually do, and conversely, one is unlikely to acquire an understanding of what designers do, without providing process support for designers. An application whose goal it is to provide both design process support for designers working in collaborative design teams, and also acquires a particular type of design process representationof design processes, is described.

title	Computation-Universal Voxel Automata as Material for Generative Design Education
source	International Conference on Generative Art
summary	This paper is a report on the educational application of a voxel automata system for massively parallel execution of computation-universal cellular units in the generative design field. The software, designed and co-developed by the author to enable developmental strategies in generative design - for example with respect to 3D design generation, semantic self-evaluation and self-replication - was applied in teaching at the School of Design at The Hong Kong Polytechnic University to achieve two goals: to teach programming as part of the School’s Interactive Systems Design stream and to teach generative concepts at a theoretical, yet hands-on and highly intensive level. An introduction to the software, its development and its functions as well as a discussion of the teaching/learning experience is given, highlighting design educational aspects and student design work. The paper concludes with an analysis of how student approaches to generative concepts have been affected by the tool and how ideas and feedback from students have supported the ongoing development of the voxel automata system and its documentation.

title	Interactive Tools for Collaborative Architectural 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	Today’s rapidly changing society is continuously developing towards an increased demand for multistakeholder knowledge and influence in the architectural planning and design process. Accordingly, we are working with developing and setting up a partner engaged collaborative design process. It includes active collaboration between users, external partners and designers, and visualizations in conceptual design and scenario building. My research is focusing on integrating visualization technology in theseprocesses by application of digital tools. We have developed a working prototype for an interactive design tool. The prototype is an extremely “easy to use” digital modeling tool called “ForeSite Designer.” With this tool one builds one’s own spatial environment with elements on a 2D surface.With one command the 2D layout is exported to a lit-up 3D/Virtual Reality world in the computer game “Half-Life”. ForeSite Designer has lately been used in a series of workshops together with external users. In these processes ForeSite Designer has played a crucial role as an arena of building spatially arranged concepts of future environments. The results show that it works, and, importantly, promotes a collaborative engagement among the users.

title	Perceptual Evaluation of the Spatial Manifestations of Urban Structures
source	Environmental Simulation - New Impulses in Planning Processes [Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1]
summary	The objective of this contribution is to bring to the attention of the community of experts in the field of architectural simulation the interdependence of the spatial manifestations of material components of urban environments and the phenomena of visual perception and imagination which we practically employ in education, professional design and which we also try to use in our contact with the clients. The way towards finding new qualities of urban environments should be dominated by our efforts to understand and perceive the urban structure as a real space-time manifestation, which is being mediated to the user also as a sensually experienced image (scene). Its atmosphere and informative content give impulses for an individualized reaction from various aspects. The content of the experience is multileveled and the sensorial effects of its iconic components can be precisely verified by means of simulation processes in temporal sequences. Taking these aspects as basis, we are developing methods, which would by taking determined conditions into consideration, broaden the spectrum of research, verification, or evaluation of the real spatial manifestations and interactive actions in situ as well as their possible anticipation and performance in laboratory conditions. Perceptual simulation is, together with the significance of experiencing and evaluating the urban environment in the eye-level horizon, a starting point of spatial model simulation methods as a supportive experimental creative and verification tool. The new information technologies and the creative technical cooperation of analog and digital iconic simulation systems create unconventional possibilities for exact recording of information and impulses for the complicated transformational process engaging more actively the community in their participation.

title	Information Amount Measurement in Generative Systems:An Objective Approach to Termination
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Termination in computational generative systems is linked increasingly to user intervention: the generative system concludes when the user chooses it to do so. The similarities between this approach to termination and the creative artistic process suggest that the products of generative systems are amenable to analysis in terms of well-formedness leading to a formal measure that acts as an automatic termination trigger. The paper proposes that such a measure can be derived from structural information theory. By applying the compression of structural information theory to meaningful principles of a design world we derive a consistent, universal description of the design result at any given state. This description expresses the correlation of the design with its formal constraints, as well as the general perception of the design’s patterns.
