title Cognitive Biases - The case of tropical architecture
source Delft University of Technology
summary This dissertation investigates, i) How cognitive biases (or illusions) may lead to errors in design thinking, ii) Why architects use architectural precedents as heuristics despite such possible errors, and iii) Develops a design tool that can overcome this type of errors through the introduction of a rebuttal mechanism. The mechanism controls biases and improves accuracy in architectural thinking. // The research method applied is interdisciplinary. It employs knowledge from cognitive science, environmental engineering, and architectural theory. The case study approach is also used. The investigation is made in the case of tropical architecture. The investigation of architectural biases draws from work by A. Tversky and D. Kahneman in 1982 on “Heuristics and biases”. According to Tversky and Kahneman, the use of heuristics of representativeness (based on similarity) and availability (based on ease of recall and imaginability) for judgement of probability can result in cognitive biases of illusions of validity and biases due to imaginability respectively. This theory can be used analogically to understand how errors arise in the judgement of environmental behaviour anticipated from various spatial configurations, leading to designs with dysfunctional performances when built. Incomplete information, limited time, and human mental resources make design thinking in practice difficult and impossible to solve. It is not possible to analyse all possible alternative solutions, multiple contingencies, and multiple conflicting demands, as doing so will lead to combinatorial explosion. One of the ways to cope with the difficult design problem is to use precedents as heuristic devices, as shortcuts in design thinking, and at the risk of errors. This is done with analogical, pre-parametric, and qualitative means of thinking, without quantitative calculations. Heuristics can be efficient and reasonably effective, but may not always be good enough or even correct, because they can have associated cognitive biases that lead to errors. Several debiasing strategies are discussed, and one possibility is to introduce a rebuttal mechanism to refocus the designer’s thinking on the negative and opposite outcomes in his judgements, in order to debias these illusions. The research is carried out within the framework of design theory developed by the Design Knowledge System Research Centre, TUDelft. This strategy is tested with an experiment. The results show that the introduction of a rebuttal mechanism can debias and improve design judgements substantially in environmental control. The tool developed has possible applications in design practice and education, and in particular, in the designing of sustainable environments.

title The End of Methodology - Towards New Integration
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary The present paper is devoted to the deliberation on the genesis and development of designing from the point of view of the potential use of computers in the process. Moreover, it also presents the great hopes which were connected with the use of the systematic designing methods in the 1960’s, as well as the great disappointment resulting from the lack of concrete results. At this time a great deal of attention was paid to the process of design as a branch of a wider process of problem-solving. Many people believed that the intuitive methods of design traditionally used by architects were incapable of dealing with the complexity of the problems to be solved. Therefore, the basic problem was the definition of a vertical structure of the designing process, which would make it possible to optimise each process of architectural design. The studies of design methodology directed at the codification of the norms of actions have not brought about any solutions which could be commonly accepted, as the efforts to present the designing process as a formally logical one and one that is not internally “uncontrary” from the mathematical point of view, were doomed to fail. Moreover, the difficulties connected with the use of the computer in designing were caused by the lack of a graphic interface, which is so very characteristic of an architect’s workshop. In result, the methodology ceased to be the main area of the architect’s interest and efforts were focused on facilitating the method of the designer’s communication with the computer. New tools were created, which enabled both the automatic generation of diversity and the creation of forms on the basis of genetic algorithms, as well as the presentation of the obtained results in the form of rendering, animation and VRML. This was the end of the general methodology of designing and the beginning of a number of methods solving the partial problems of computer-supported design. The present situation can be described with the words of Ian Stewart as a “chaotic run in all directions”. An immediate need for new integration is felt. Cyber-real space could be a solution to the problem. C-R-S is not a virtual reality understood as an unreal world. Whilst VR could be indeed treated as a sort of an illusion, C-R-S is a much more realistic being, defining the area in which the creative activities are taking place. The architect gains the possibility of having a direct contact with the form he or she is creating. Direct design enables one to creatively use the computer technology in the designing process. The intelligent system of recognising speech, integrated with the system of virtual reality, will allow to create an environment for the designer – computer communication which will be most natural to the person. The elimination of this obstacle will facilitate the integration of the new methods into one designing environment. The theoretical assumptions of such an environment are described in the present paper.

title GDL Object
source The Architect’s Journal, 14 June 2001, pp. 49-50
summary It is all too common for technology companies to seek a new route to solving the same problem but for the most part the solutions address the effect and not the cause. The good old-fashioned pencil is the perfect example where inventors have sought to design-out the effect of the inherent brittleness of lead. Traditionally different methods of sharpening were suggested and more recently the propelling pencil has reigned king, the lead being supported by the dispensing sleeve thus reducing the likelihood of breakage. Developers convinced by the Single Building Model approach to design development have each embarked on a difficult journey to create an easy to use feature packed application. Unfortunately it seems that the two are not mutually compatible if we are to believe what we see emanating from Technology giants Autodesk in the guise of Architectural Desktop 3. The effect of their development is a feature rich environment but the cost and in this case the cause is a tool which is far from easy to use. However, this is only a small part of a much bigger problem, Interoperability. You see when one designer develops a model with one tool the information is typically locked in that environment. Of course the geometry can be distributed and shared amongst the team for use with their tools but the properties, or as often misquoted, the intelligence is lost along the way. The effect is the technological version of rubble; the cause is the low quality of data-translation available to us. Fortunately there is one company, which is making rapid advancements on the whole issue of collaboration, and data sharing. An old timer (Graphisoft - famous for ArchiCAD) has just donned a smart new suit, set up a new company called GDL Technology and stepped into the ring to do battle, with a difference. The difference is that GDL Technology does not rely on conquering the competition, quite the opposite in fact their success relies upon the continued success of all the major CAD platforms including AutoCAD, MicroStation and ArchiCAD (of course). GDL Technology have created a standard data format for manufacturers called GDL Objects. Product manufacturers such as Velux are now able to develop product libraries using GDL Objects, which can then be placed in a CAD model, or drawing using almost any CAD tool. The product libraries can be stored on the web or on CD giving easy download access to any building industry professional. These objects are created using scripts which makes them tiny for downloading from the web. Each object contains 3 important types of information: · Parametric scale dependant 2d plan symbols · Full 3d geometric data · Manufacturers information such as material, colour and price Whilst manufacturers are racing to GDL Technologies door to sign up, developers and clients are quick to see the benefit too. Porsche are using GDL Objects to manage their brand identity as they build over 300 new showrooms worldwide. Having defined the building style and interior Porsche, in conjunction with the product suppliers, have produced a CD-ROM with all of the selected building components such as cladding, doors, furniture, and finishes. Designing and detailing the various schemes will therefore be as straightforward as using Lego. To ease the process of accessing, sizing and placing the product libraries GDL Technology have developed a product called GDL Object Explorer, a free-standing application which can be placed on the CD with the product libraries. Furthermore, whilst the Object Explorer gives access to the GDL Objects it also enables the user to save the object in one of many file formats including DWG, DGN, DXF, 3DS and even the IAI's IFC. However, if you are an AutoCAD user there is another tool, which has been designed especially for you, it is called the Object Adapter and it works inside of AutoCAD 14 and 2000. The Object Adapter will dynamically convert all GDL Objects to AutoCAD Blocks during placement, which means that they can be controlled with standard AutoCAD commands. Furthermore, each object can be linked to an online document from the manufacturer web site, which is ideal for more extensive product information. Other tools, which have been developed to make the most of the objects, are the Web Plug-in and SalesCAD. The Plug-in enables objects to be dynamically modified and displayed on web pages and Sales CAD is an easy to learn and use design tool for sales teams to explore, develop and cost designs on a Notebook PC whilst sitting in the architects office. All sales quotations are directly extracted from the model and presented in HTML format as a mixture of product images, product descriptions and tables identifying quantities and costs. With full lifecycle information stored in each GDL Object it is no surprise that GDL Technology see their objects as the future for building design. Indeed they are not alone, the IAI have already said that they are going to explore the possibility of associating GDL Objects with their own data sharing format the IFC. So down to the dirty stuff, money and how much it costs? Well, at the risk of sounding like a market trader in Petticoat Lane, "To you guv? Nuffin". That's right as a user of this technology it will cost you nothing! Not a penny, it is gratis, free. The product manufacturer pays for the license to host their libraries on the web or on CD and even then their costs are small costing from as little as 50p for each CD filled with objects. GDL Technology has come up trumps with their GDL Objects. They have developed a new way to solve old problems. If CAD were a pencil then GDL Objects would be ballistic lead, which would never break or loose its point. A much better alternative to the strategy used by many of their competitors who seek to avoid breaking the pencil by persuading the artist not to press down so hard. If you are still reading and you have not already dropped the magazine and run off to find out if your favorite product supplier has already signed up then I suggest you check out the following web sites www.gdlcentral.com and www.gdltechnology.com. If you do not see them there, pick up the phone and ask them why.

title Evolutionary Algorithms in Urban Planning
source CORP 2001, Vienna, pp. 269-272
summary The functions supported by commercial CAD software are drawing, construction and presentation. Until now, no programssupporting the creative part of architectural and urban problem solving are on the market. The grand hopes of symbolic AI ofprogramming creative architectural and urban design have been disappointed. In the meantime, methods called New AI are available.Among these methods, evolutionary algorithms are particularly promising for solving design problems. The paper presents anapproach to town panning and architectural problem solving that combines an evolutionary strategy (ES), a genetic algorithm (GA)and a Particle System. The problem that remains incapable of being solved algorithmically has to do with the fact that in architectureand urbanizm form as well as function count. Because function relates to comfort, easiness of use, and aesthetics as well, it ishopeless to fully specify the fitness function of architecture. The approach presented circumvents a full specification through dividinglabor between the software and its user. The fitness function of town plans is defined in terms only of proportions of the shapes, areasand buildings to be accommodated and topological relations between them. The rest is left to the human designer who interactivelyintervenes in the evolution game as displayed on the screen.

title Using Evolutionary Methods for Design Case Adaptation

summary Case-based reasoning (CBR) provides a methodology for directly using previous designs in the development of a new design. An aspect of CBR that is not well developed for designing is the combination and adaptation of previous designs. The difficulty with this aspect of case-based design is partly due to the extensive amounts of specialised knowledge needed to select the appropriate features of a previous design to include in the new design and the adaptation of these features to fit the context of a new design problem. In this paper we present a design process model that combines ideas from CBR and genetic algorithms (GA’s). The CBR paradigm provides a method for the overall process of case selection and adaptation. The GA paradigm provides a method for adapting design cases by combining and mutating their features until a set of new design requirements and constraints are satisfied. We have implemented the process model and illustrate the model for residential floor plan layout. We use a set of Frank Lloyd Wright prairie house layouts as the case base. The constraints used to determine whether new designs proposed by the process model are acceptable are taken from feng shui, the Chinese art of placement. This illustration not only clarifies how our process model for design through the evolutionary adaptation of cases works, but it also shows how knowledge sources with distinct origins can be used within the same design framework.

title An inquiry into computers in design: attitude before-attitudes after
source Design Studies, 22(3), pp. 255-281
summary This paper reports on the findings of an empirical investigation into the use of the computer as the only design medium. A group of students took part in an experiment to design a studio for a graphic designer on the computer. Student attitudes towards the design process were assessed at two conditions: before using the computer and after using the computer. Prior to the experiment a literature search was carried out to explore some widely researched design issues such as sketching, design creativity, and computer-aided design. Consequently a number of design variables were identified, developed and then empirically tested. Data collection methods included questionnaires and observations. Statistical analysis of the responses confirms that using the computer has produced a statistically significant difference in attitudes to the design process variables.

title Coordinating virtual building design teams

summary Most research in design project management support systems treats the subject as an isolated objective problem. The goals to be met are defined in terms of a supposed universal view of the project, and now outside concerns are taken into account. While such approaches, including project simulation, may yield excellent results, they ignore what, for many projects, are the real difficulties. Design projects are not isolated. All participants have other obligations that compete with the given project for attention and resources. The various participants in the design process have different goals. For these reasons it is proposed that design project management can be best facilitated by tools which assist the participating actors to share suitable management information in order to make better co-ordination possible, while allowing the resource balancing between projects to occur in private. Such a tool represents the design project management task as a negotiation task that spans both projects and firms; the management of one project is the management of all. The model of design collaboration upon which the Design Coordination System (DeCo) is built was developed from 1) a heuristic case study used to gain insight into the ways in which designers co-ordinate their efforts, and 2) the application of the theory of the social contract as developed by John Rawls to the problem of design project management. The key innovation in the DeCo system is the shaping of the project management system around existing practices of collaborative project design management and planning. DeCo takes advantage of how designers already co-ordinate their work with each other and resolve disputes over deadlines and time lines. The advantage of DeCo is that it formalises these existing practices in order to accommodate both the increasing co-ordination burden and the difficulties brought about by the internationalisation of design practice. DeCo, the design project management system proposed here, provides a representation, a communications protocol, and a game theoretical decision structure. The combination of these three units provides users with the ability to exchange structured pictures of the project as seen from the points of view of individual actors. Further, it suggests a mechanism based on a specific principle of fairness for arriving at mutually acceptable project plans. The DeCo system permits the users freedom to manage their design processes as they will, while providing a basic compatibility between practices of design team members which supports their collaborative efforts to co-ordinate their design work.

summary Design educators attempt to train the eyes and minds of students to see and comprehend the world around them with the intention of preparing those students to become good designers, critical thinkers and ultimately responsible architects. Over the last eight years we have been developing the digital media curriculum of our architecture program with these fundamental values. We have built digital media use and instruction on the foundation of our program which has historically been based in physical model making. Digital modeling has gradually replaced the capacity of physical models as an analytical and thinking tool, and as a communication and presentation device. The first year of our program provides a foundation and introduction to 2d and 3d design and composition, the second year explores larger buildings and history, the third year explores building systems and structure through design studies of public buildings, fourth year explores urbanism, theory and technology through topic studios and, during the fifth year students complete a capstone project. Digital media and CADD have and are being synchronized with the existing NAAB accredited regimen while also allowing for alternative career options for students. Given our location in the Los Angeles region, many students with a strong background in digital media have gone on to jobs in video game design and the movie industry. Clearly there is much a student of architecture must learn to attain a level of professional competency. A capacity to think visually is one of those skills and is arguably a skill that distinguishes members of the visual arts (including Architecture) from other disciplines. From a web search of information posted by the American Academy of Opthamology, Visual Acuity is defined as an ability to discriminate fine details when looking at something and is often measured with the Snellen Eye Chart (the 20/20 eye test). In the context of this paper visual acuity refers to a subject’s capacity to discriminate useful abstractions in a visual field for the purposes of Visual Thinking- problem solving through seeing (Arnheim, 1969, Laseau 1980, Hoffman 1998). The growing use of digital media and the expanding ability to assemble design ideas and images through point-and-click methods makes the cultivation and development of visual skills all the more important to today’s crop of young architects. The advent of digital media also brings into question the traditional, static 2d methods used to build visual skills in a design education instead of promoting active 3d methods for teaching, learning and developing visual skills. Interactive digital movies provide an excellent platform for promoting visual acuity, and correlating the innate mechanisms of visual perception with the abstractions and notational systems used in professional discourse. In the context of this paper, pedagogy for building visual acuity is being considered with regard to perception of the real world, for example the visual survey of an environment, a site or a street scene and how that visual survey works in conjunction with practice.

title Exploiting Tools of Evaluation to Improve CAAD Teaching Methods. A Case Study of Inter & Intra ECTM Model
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 215-230
summary This paper reports on an ongoing research study model into the Evaluation of CAAD Teaching Methods (ECTM) of which a number of resolutions and strategies were attained via an empirical investigation. The first stage of the study findings proposed a framework for the evaluation of architecture courses in tandem with CAAD. The second stage was based on the Inter & Intra ECTM design model as a strategy for acquiring solutions to CAAD problems through the exploitation of CAAD evaluation tools. The ECTM model structure criteria: the Model Concepts, the Operational Context, Dialectic Meanings, Relational Context, Performing Methods and Level of Integration were illuminated. ECTM model has a twofold involvement junctures, which describe CAAD evaluation behaviour. The first involves the evaluator in an interdepartmental comparison of CAAD integration into the curriculum, and/or between schools of architecture. The second engages the evaluator in an intradepartmental study of CAAD integration, and within the institution. The study projected an attempt to validate the Inter & Intra ECTM design model in concert with evaluation. The paper presents an extended description of the objectives, procedures and testing designed for the two abovementioned junctures composing the proposed ECTM case studies. Sequences of methods of data collection employed as a vehicle for the ECTM were Kirkpatrick model, questionnaire survey, observation (using an ECTM checklist) and experimental studies. The paper also explores variables and indicators used, and advances to shed some light on the methods of statistical analysis employment. ECTM model as a tool to attain CAAD effectiveness might redefine the role of collaborators/ team partnerships in CAAD tuition; and induce the level of technology selection and adaptation amongst schools, e.g. tutors and coursework interconnectivity. The ECTM model may also work as a framework of strategies to augment interactivity and positive learning amongst both staff and students.

title Virtual Science: Virtuality and Knowledge Acquisition in Science and Cognition
source Virtual Reality: Cognitive Foundations, Technological Issues & Philosophical Implications. Frankfurt am Main: Peter Lang
summary The focus of this paper is the process of knowledge acquisition (KA) and which role virtuality plays in this context. We argue that there are three different modes of knowledge acquisition which can be identified both in the domains of cognition and science: the empirical, the "constructive", and the "synthetic" mode. We show that the method of constructing knowledge in the virtual domain (i.e., the synthetic mode of KA) is not only a principal mode of KA in our cognition (e.g., thought experiments, making plans, etc.). It becomes increasingly important in the field of (natural) science in the form of simulations and virtual experiments. The attempt to find an answer to the question of whether simulation can be an information source for science, and to validate the computational approach in science, leads to a new interpretation of the nature of virtual models. This new perspective renders the problem of "feature extraction" obsolete.

title BioIcons
source International Conference on Generative Art
summary BioIcons are images developed with artificial life, especially modified Cellular Automata to simulate a sort of living artistic tool. Each image is a spontaneous creation of Artificial Life: different shapes and colors are assigned to each cell of the digital being; this is done linking the “biological” state of each cell and the auto similarity existing between the cell and the digital being as a whole. The resulting picture is like a microscopic view, because we can endlessly magnify portions of the image, using this process to reach, conceptually and visually, the integration between Fractals andArtificial Life. BioIcons, as the rest of my work, is the product of my programming efforts: I think that using proprietary algorithms supports autonomy and originality. I started this work studying Cellular Automata algorithms; some of them are mutations of classic Cellular Automata, others are my own creations. After that, I studied how to force the Cellular Automata to behave like an artistic tool, introducing special parameters linked with color theory, perception and auto similarity. Finally, I studied an interface in such a way to allow interaction between the artificial artists and the user, and to transform the image into an interactive and dynamic process. The dynamic interactions between the piece of art and the public, the transformation of the artistic process into something open and free and the close connections between art and investigation are the orienting ideas of my artistic effort. Yet I’m also concerned with digital technology as it should be applied to art, mainly to discover the medium’s artistic language. I consider of great importance, for my artistic development, the opportunity to integrate my strong love for nature and life with art and mathematics, with the help of computer technologies.

title Exploring the Roles of Exploring the roles of Sketches and Knowledge in the Design Process
source The University of Sydney, Faculty of Architecture
summary The needs of computational tools provide the motivation to have a better understanding of the roles of knowledge and sketches in the design process. The inadequacies of current computer-aided conceptual design tools result from our vague comprehension of the nature of the design process. The hypothesis of this study is that the design process involves interlocked and multi-mode processes in which design knowledge and sketches interact with each other to advance the design process. These interactions make current computer-aided design systems unsatisfactory in the conceptual design process. The understanding of these interactions would provide the foundation of more useful computational tools and potentially play a role in developing better pedagogical methods.

This research utilized both process-oriented and content-oriented coding schemes to examine different aspects of the design process. Concurrent and retrospective protocols were analyzed to determine their utility in revealing the design processes. Retrospective protocols and the content-oriented coding scheme were selected for design cognition studies in this research, and the procedures of experiments and analyses were described in detail.

The results of encoded protocols were presented in terms of segments, levels, and instances. They represented the design process in a way that enabled us to observe the interactions among sketches, knowledge, and different cognitive levels.

The examination of the conceptual design process demonstrated its features of interlinked levels and multiple modes; even one snippet of the process contained various modes and sub-processes. The shifting speed of intentions and the vagueness of sketches and functional references were also shown.

The study of the meditated roles of the sketches and knowledge in the design process shows the following. First, sketches are the affordances of perceptual and functional instances while designing. Most of the sketches made by designers are multi-functionally bounded. Second, design knowledge plays various roles in the conceptual design process. The ubiquitous designerly way of knowing demonstrates the differences between active developing and passive utilizing design knowledge. Finally, one of the roles of design sketches and knowledge is shown to be the connector among different cognitive levels in the design process.

The unpredictability of the design process is demonstrated in the results. Design knowledge provides previously generated solutions for the problem at hand, and design situatedness describes the phenomenon that a designer uses his/her experience to produce novelty and innovation. A method to measure the design innovation through an encoded protocol is proposed based on the concept of situated creativity.

The implications for future computer-aided design systems are presented based on the roles of sketches, knowledge, and situatedness in the interlinked and multimode design process. The concept of cognition-oriented CAD is proposed to provide empirical clues to improve current CAD systems.

title Mouse.class: Experiments for Exploring Dynamic Behaviors in Urban Places
source University of Washington, Design Machine Group
summary Urban space comprises not only physical forms - buildings, streets, plazas, trees, etc. – but also the people 'acting on them'. The purpose of this thesis is to increase our awareness of behavior and environment relationships, focusing on local movement at the individual level in a pedestrian environment. The thesis describes the experiment Mouse.class, as a concept demonstration model, which allows users to create a 2D-virtual environment for accommodating autonomous agents, Mouse, to explore (pedestrian) dynamic behavior in relation to (urban) space. The program uses multi-agent technology to construct an individual-based simulation in which each agent employs individual behaviors. The agents have abilities to navigate through the environment using a behavior rule set derived from a wide range of research – both theoretical and empirical approaches – on spatial behavior in small-scale urban space. These simulated individuals also have the ability to improvise their actions according to the situations they find themselves in. In the simulation, each agent reacts to the space configuration, to specific attractions in the environment, as well as to other mice. The local movement of an individual is, therefore, the result of the interaction of its visual perception, motivation, and social actions. The program then tracks each movement – path of use – revealing patterns that emerge from interactions among the components of the environment. The exploration seeks to develop a way urban designers think of 'space' as fluid processes and recognize that objects in the urban environment can have radically differing effects, depending on the circumstances and contexts in which they exist. Indeed, people are parts of the environment.

title Analysis and the descriptive approach

summary The rise of consciousness concerning the quality of working and living conditions has been a permanent though frequently underplayed theme in architecture and building since the reconstruction period. It has led to an explosive growth of programmatic requirements on building behaviour and performance, thus also stimulating the development of design analysis. The first stage of development was characterized by the evolution of prescriptive systems. These reversed the structure of pre-existing proscriptive systems into sequences of known steps that should be taken in order to achieve adequate results. Prescriptive systems complemented rather than replaced proscriptive ones, thereby creating an uncertain mixture of orthodoxy and orthopraxy that failed to provide design guidance for improving design performance and quality.The second stage in the development of design analysis focuses on descriptive methods and techniques for analyzing and supporting evaluation. Technologies such as simulation and scientific visualization are employed so as to produce detailed, accurate and reliable projections of building behaviour and performance. These projections can be correlated into a comprehensive and coherent description of a building using representations of form as information carriers. In these representations feedback and interaction assume a visual character that fits both design attitudes and lay perception of the built environment, but on the basis of a quantitative background that justifies, verifies and refines design actions. Descriptive analysis is currently the most promising direction for confronting and resolving design complexity. It provides the designer with useful insights into the causes and effects of various design problems but frequently comes short of providing clear design guidance for two main reasons: (1) it adds substantial amounts of information to the already unmanageable loads the designer must handle, and (2) it may provide incoherent cues for the further development of a design. Consequently the descriptive approach to analysis is always in danger of been supplanted by abstract decision making.One way of providing the desired design guidance is to complement the connection of descriptive analyses to representations of form (and from there to synthesis) with two interface components. The first is a memory component, implemented as case-bases of precedent designs. These designs encapsulate integrated design information that can be matched to the design in hand in terms of form, function and performance. Comparison between precedents with a known performance and a new design facilitate identification of design aspects that need be improved, as well as of wider formal and functional consequences. The second component is an adaptive generative system capable of guiding exploration of these aspects, both in the precedents and the new design. The aim of this system is to provide feedback from analysis to synthesis. By exploring the scope of the analysis and the applicability of the conclusions to more designs, the designer generates a coherent and consistent collection of partial solutions that explore a relevant solution space. Development of the first component, the design case-bases, is no trivial task. Transformability in the representation of cases and flexible classification in a database are critical to the identification and treatment of a design aspect. Nevertheless, the state of the art in case-based reasoning and the extensive corpus of analysed designs provide the essential building blocks. The second component, the adaptive generative system, poses more questions. Existing generative techniques do not possess the necessary richness or multidimensionality. Moreover, it is imperative that the designer plays a more active role in the control of the process than merely tweaking local variables. At the same time, the system should prevent that redesigning degenerates into a blind trial-and-error enumeration of possibilities. Guided empirical design research arguably provides the means for the evolutionary development of the second component.

summary Professional design offices claim that our graduates have difficulties with their free-hand perspective drawing skills. This fact, which has become obvious over the last 5 years, is parallel to a clear tendency towards the use of 3-dimensional digital imagery in the projects of our students. Frequently, faculty tends to blame the computer for the shortcomings of our students in the use of traditional media, yet there is no clear evidence on the source of the blame. At a more fundamental level, the visualization skills of our students are questioned. This paper will explain how faculty teaching design communication techniques, with traditional and digital media, are working together in the development of a teaching methodology that makes use of computers in support of our student’s training on cognitive visualization skills, namely; “The Third-Eye Method”. The paper describes the Third-Eye Method as an alternative to traditional methods. As evidence of the benefits offered by the Third-Eye Method, the paper presents the results of testing it against traditional methods among freshman students. At the end, the paper draws as conclusion that computers are not the main source of the problem but a potential solution.

summary Today the multimedia technology offers us an undeveloped world of resources. But these resources are not didactic themselves; they depend on the way they are used. The management of new variables, such as interactivity, redundancy, will allow to reach a superior level in relation to that of the attraction/fascination, characteristic of the digital means. Under this conceptual base, an investigation project is developed with the objective of constructing a didactic multimedia, strongly determined by the characteristics of the topic SEISMIC PREVENTION, and guided specifically to the construction of preventive BEHAVIORS, before, during and after the occurrence of an earthquake.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title Designers‚ Cognition in Traditional versus Digital Media during Conceptual Design
source Bilkent University Ankara Turkey
summary Designers depend on representations to externalize their design thoughts. External representations are usually in the form of sketches (referred to as traditional media) in architectural design during the conceptual design. There are also attempts to integrate the use of digital representations into the conceptual design in order to construct a digital design medium. This thesis aims at gaining an insight on designers’ cognitive processes while sketching in digital versus traditional media. The analysis of cognitive processes of designers based on their protocols is necessary to reveal their design behavior in both media. An experiment was designed employing six interior architects (at Bilkent University) solving an interior space planning problem by changing the design media they work with. In order to encode the design behavior, a coding scheme was utilized so that inspecting both the design activity and the responses to media transition was possible in terms of primitive cognitive actions of designers. The analyses of the coding scheme constituents, which are namely segmentation and cognitive action categories enabled a comparative study demonstrating the effect of the use of different media in conceptual design phase. The results depicted that traditional media had advantages over the digital media such as supporting perception of visual-spatial features, and organizational relations of the design, production of alternative solutions and better conception of the design problem. These results also emerged implications for the computer aid in architectural design to support the conceptual phase of the design process.

title On Developing Standards for the Creation of VR City Models
source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 404-409
doi https://doi.org/10.52842/conf.ecaade.2001.404
summary The paper is an inclusive summary of research work on creating VR city models carried out over the last six years in the UK and Greece aiming to put into discussion the guidelines/ rules developed by the author. The paper is structured in three sections referring to the main stages in terms of either technical expertise and problem solving or conceptual structuring of information: creation of 3D city models, CAAD versus VR in digital city modelling and finally utilizing digital city models. The expected outcome of the work presented is the establishment of a body of knowledge that will facilitate the development of standards and guidelines for the creation of city models. There are obvious advantages in having a compatible set of city 3D models. On the other hand, there are different rules to be followed and issues to be solved, according to the scale of the model, level of detail that is needed—all these rules relate to the projected use of the model.

summary It has been designed and developed a system Web that has video in real time and an interactive product catalogue based on pseudo-three-dimensional models, that is to say, models that they pretend to be three-dimensional, but that in fact do not have geometry 3D properly in the memory, but of an appropriate composition according to the case of geometry 2D (image or any graph), that allows to see the model from several points of view and to consult additional information (weight, material, dimensions, etc.). They have been analyzed and proven the different formats from transmission of video and audio by Internet, studying all its parameters, until finding the optimal ones for this server. In comparison with the use of format VRML (Virtual Reality Modeling Language) used commonly to put models 3D in the Web, this system that we have devised presents like advantages the low time of load, the high precision of the views of the object and the low cost of maintenance of the Web. On the other hand, one does not have the infinity of views and facility of manipulation of the VRML.
