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.

summary “Genetic architectures”, not only like a metaphorical name. New materials and new tools give a new architecture. Up to now the human being had to conform with acting only at the superficial level of objects. Now, it’s possible to think further away and descend to actions at the molecular level, influencing on genetic design and on programming chains which are then developed by themselves as artificial computing elements and natural live elements. It’s time to apply all these to architecture, when these can become an integrating part of architecture. These should include an advanced contemporary architecture versus (and basing itself on) the use of the computer as a mere substitute of manual drafts while improving pintoresque ecology: “the new cibernetic-digital architectural design & the new ecological-environmental architectural design”. Not building in the nature, building with the nature, building the nature self. The utopy of today is the reality of tomorrow.

title Can a Genetic Algorithm Think Like a Composer?
source International Conference on Generative Art
summary There has now been a substantial body of work utilising Genetic Algorithms (GA) for the purpose of musical composition. A common point of discussion is how far GA’s can simulate not just the musical output of human composers, but also the process of composing itself. This paper begins by discussing the suitability of using a GA for composition, and goes on to describe a generative music system (by the author), that utilises a domain specific, knowledge rich GA. The system acts on a supplied 2-bar musical phrase (up to 4 parts), and evolves musical fragments towards a supplied target. The aim is to provide interim points on the evolutionary path, which represents a ‘new’ musical ideas audibly based on the supplied fragments. The paper concludes that the system is able to model at least part of the creative process of composition, and is effective at producing musically successful results. (Audio download sources of its output are included to support this conclusion). The system was used to generate music included in an interactive installation work, exhibited at Brighton Arts Festival 2002, and other applications under developed that use the algorithm are discussed.

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 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.

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 Artificial Design and Planning Support: Interactive Plan Generation andCoordination in Distributed Decision-Making
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 In this paper we discuss some basic issues pertaining to artificial plan design as a paradigm for architectural design and urban planning support. We present a model for artificial design generation based on learning control methodologies. Plan design is seen as a search for "coordinated" solutions (changes) that satisfy distributed domain requirements and views expressed by human or artificial agents. Learning control is used as a method to search for solutions that direct partial descriptionsproduced by agents, to follow their dynamically defined targets -despite conflicting requirements. The model is simulated for land use and layout plan design, involving decisions for the location and physical configuration of a hypothetical housing and retail development.

summary Taking as a starting point the hypotheses that the urban body is a self-adapted ecology made of material and non-material components (Bateson, 1972), relationships between elements are examined in an attempt to destabilize the static division of matter and idea and to inquire into those relationships that determine the structural coupling (Maturana, 2002) between body and environment, as well as the constitution of the body itself. Contemporary technology is used in order to trace these alterations and the urban body is examined as a network configuration. The importance of the methodology adopted by the current research lies in the fact that social and economic factors merge with spatial characteristics, allowing for a visualization and re-interpretation of the urban body mutations based on self-adapted reconfigurations and for a prediction of the structural alterations made possible through the reconfiguration of the synaptic forces between elements.

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.

title Evolution of Media for Early Design Stages
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 this paper the evolution of media used at early design stages will be considered. In traditional methods of searching and presenting the design idea, the basic tool used was the graphic representation. Implementation of new digital techniques in 60s - 70s focused on the mathematical way ofrepresentation. These methods were “not architect friendly” (lack of graphic representation traditionally used by architects). As a result, the development of methods for digital support of form searching was terminated. The computer was used as a tool for drafting. Creative usage of computers for form searching through sketching on the display was extremely difficult. The computer could be described as an “incompatible pencil”. Only in recent years can we see new efforts in this area ofdesign methodology. Thanks to new technical possibilities we have a new chance for changing the process of designing. New kinds of software and hardware let us use the computer not as a pen, but as a medium. In this paper different new ways of form searching will be considered (from very simple method as the scansketches to very complicated ones, such as the generic algorithms). At the end, the influence of new media on the process of design will be presented.

title Design Decision Support through Translation between Multiple Representations of Spatial Data
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Urban planning and urban design involve collaboration of diverse participants with multiple agendas and multiple criteria. The participants typically use multiple representations of spatial data to derive inferences and insights about the planning problems, leading to a shared decision-making process. To support such multidisciplinary work, this paper proposes a new computational approach and technique for translation between multiple representations of spatial data. This approach is designed to supportdesign decision-making in the interrelated interests of design participants. Prototype implementation and evaluation are conducted to test and validate the proposals.

title Faculties of Architecture
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 order to be inscribed in the European Architect’s register the study program leading to the diploma ‘Architect’ has to meet the criteria of the EC Architect’s Directive (1985). The criteria are enumerated in 11 principles of Article 3 of the Directive. The Advisory Committee, established by the European Council got the task to examine such diplomas in the case some doubts are raised by other Member States. To carry out this task a matrix was designed, as an independent interpreting framework that mediates between the principles of Article 3 and the actual study program of a faculty. Such a tool was needed because of inconsistencies in the list of principles, differences between linguistic versions ofthe Directive, and quantification problems with time, devoted to the principles in the study programs. The core of the matrix, its headings, is a categorisation of the principles on a higher level of abstractionin the form of a taxonomy of domains and corresponding concepts. Filling in the matrix means that each study element of the study programs is analysed according to their content in terms of domains; thesummation of study time devoted to the various domains results in a so-called ‘profile of a faculty’. Judgement of that profile takes place by committee of peers. The domains of the taxonomy are intrinsically the same as the concepts and categories, needed for the description of an architectural design object: the faculties of architecture. This correspondence relates the taxonomy to the field of design theory and philosophy. The taxonomy is an application of Domain theory. This theory,developed by the authors since 1977, takes as a view that the architectural object only can be described fully as an integration of all types of domains. The theory supports the idea of a participatory andinterdisciplinary approach to design, which proved to be awarding both from a scientific and a social point of view. All types of domains have in common that they are measured in three dimensions: form, function and process, connecting the material aspects of the object with its social and proceduralaspects. In the taxonomy the function dimension is emphasised. It will be argued in the paper that the taxonomy is a categorisation following the pragmatistic philosophy of Charles Sanders Peirce. It will bedemonstrated as well that the taxonomy is easy to handle by giving examples of its application in various countries in the last 5 years. The taxonomy proved to be an adequate tool for judgement ofstudy programs and their subsequent improvement, as constituted by the faculties of a Faculty of Architecture. The matrix is described as the result of theoretical reflection and practical application of a matrix, already in use since 1995. The major improvement of the matrix is its direct connection with Peirce’s universal categories and the self-explanatory character of its structure. The connection with Peirce’s categories gave the matrix a more universal character, which enables application in other fieldswhere the term ‘architecture’ is used as a metaphor for artefacts.

title APPROPRIATE LEVELS OF ACCESS: AN EMPIRICAL STUDY ON THE AVAILABILITY OF COMPUTERS IN STUDIO

doi https://doi.org/10.52842/conf.acadia.2003.119
summary One of the most significant technological challenges facing architecture schools today is how to provide an appropriate level of access to computing resources. As the computer has become a significant tool in the study and practice of architecture, students need to have access to that tool in order to further their studies. But in facing this question of access, what is “appropriate”? Is there such a thing as too much access? Is 1:1 access—a computer for every student—the minimum level of access that schools and students should accept? Or is there a point beyond which more resources just means more waste; computers sitting idle and unused, or students using the computer for unproductive ends? These questions were the subject of an experimental series of studios in the spring of 2002, wherein three studios were given varying numbers of computers for a term. The use of these computers was then tracked, and compared with previous terms. In tandem, the quality of work produced by these three studios was compared. While additional experiments are most likely needed to draw firm conclusions, the results of this experiment seem to support defining “an appropriate level of access” at less than 1:1.

title GenJam in Transition: from Genetic Jammer to Generative Jammer
source International Conference on Generative Art
summary GenJam, short for Genetic Jammer, is an evolutionary computation (EC) based software agent that models a jazz improviser. Recently GenJam has evolved away from its roots as an interactive genetic algorithm toward its current state as an autonomous generative system. GenJam has retained its chromosome-based representations and mappings, its intelligent selection, crossover and mutation operators, and its real-time interactive performance capabilities. However, it no longer needs any explicit representation of fitness, which arguably makes it no longer an EC system. This paper considers GenJam as a generative art system. Generative art produces “unique and non-repeatable events” that express a designer’s generating idea. The designer’s generating idea defines a species of events, represented in a genetic code. In music, these events could be individual notes, melodic phrases, even entire pieces. In GenJam the events are four-measure phrases, or “licks” in the jazz vernacular. The format for the genetic code, then, defines a species space from which unique individual events can be generated. Uniqueness is important in jazz because improvisation must be spontaneous and “new.” Hence, improvisation is tailor-made for the generative art paradigm, and in fact, one could argue that improvisation is, by definition, the purest example of generative art applied to music. In other words, generative music is improvisation, and GenJam is the Generative Jammer.

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.

summary If the result of computer innovations can be interpreted as an emerging “difference” in the quality of constructed space, then in order to truly understand what future applications may be regarding architecture at present, we should look at what advanced functions are available in the process of designing forms and space (DeLuca and Nardini, 2002). Recently the so called parametric approach, a technique for describing a large class of designs with a small description in programming code, has become a focus of attention in architectural computing. In this paper, we reflect on the current use of parametric tools using real case studies as well as our own proof of concept parametric programmes and report on how the avant-garde computer techniques may help to increase the quality of residential building.

summary Most departmental computing infrastructure reflects the state of networking technology and available funds at the time of construction, which converge in a preconceived notion of homogeneity of network architecture and usage patterns. The DMAN (Digital Media Access Network) project, a large-scale server and network foundation for The Hong Kong Polytechnic University’s School of Design, was created as a platform that would support a highly complex academic environment while giving maximum freedom to students, faculty and researchers through simplicity and ease of use. As a centralized multi-user computation backbone, DMAN faces an extremely heterogeneous user and application profile, exceeding implementation and maintenance challenges of typical enterprise, and even most academic server set-ups. This paper summarizes the specification, implementation and application of the system while describing its significance for design education in a computational context.
