summary	What is the role of CAAD as a tool of architectural form creation ? We used to over-estimate the role of computer as significant factor of design process. In fact it serves only to produce technical documentation and to visualise designed buildings. We usually use CAAD to record ideas, not to create designs. We use it like more complex pencil. But it is unsuitable for conceptual design , with imperceptible influence on idea definition. Its practical usefulnes is limited. I would like to consider and find out reasons of that state, present some conclusions and ideas on computer aided architectural form creation. Many tools were invented to extend posibilities of human body or intellect. Microscop and telescop are extensions of human eye. Which organ is extended by computer (especially by CAAD)? CAAD with high developed function of visualising of the object beeing designed seems to be an extension of architect's imagination. It is beeing used to foresee visual efects, to check designed forms, to see something what we are not able to imagine. It performes the role of electronic modeler. Real model and virtual model - the medium of presentation is diferent but ways of using them are similar . Dislocation of place where we build model is not a big achievement, but potential possbilities of CAAD in modeling are almost unlimited (?). What are special features of CAAD as a modeling tool? First we have to consider what is indispensible when building a model: to embody idea. To do this we need space, substance and tools. In architectural design practice space is a real site with definite climate, neigbourhood, orientation. Substance that we shape is an archiectural form composed of many difrent elements: walls, windows, roof, entry, ... , proportions, rhythm, emotions, impresions... The tool is: our knowledge, imagination, talent, experience, norms, law and drawing equipment. Working with the computer, making virtual model, we have many of mentioned elements given in structure of CAAD program and interpreted by it. But many of them have different character. Making traditional dummy of building we operate on reality which is manually accessible. In case of computer model we operate on information. Space, substance and tool (- program) are informations, data. Human being is not an abstract data processor, but creature that lives non stop in close, direct, sensual contact with nature. By this contact with enviroment collects experiences. Computer can operate on digital data that is optionally selected and given by user, independent upon enviromental conditions. Usually architecture was created on basis of enviroment, climate, gravity. But these do not exist in CAAD programs or exist in the symbolic form. Character of these conditions is not obvious. We can watch demeanour of objects in gravity but it can be also antigravity. In theory of systems everything is considered as a part of biger system. In "virtual" reality (in computer space) we deal with accurences which are reduced to abstract level, free upon terms or connections. We work with our CAAD software using geometric space whithout any other principle.

title	Virtual Reality in Architecture
doi	https://doi.org/10.52842/conf.ecaade.1994.x.e4i

summary	This short presentation will describe the application of a Virtual Reality system for the architectural design process. This is based on the results of research into 6 technology and in particular on the possibilities of a natural interface between a designer and a design system. This description is also based on the development of a laboratory setup for a “fully immersive” (all-round representation) and a “partially immersive” (stereo representation) 6 application. This application offers a designer the possibility of modify-ing and assessing a 3D design model in “Virtual Reality” This presentation is mainly based on the use of Virtual Reality in the course of several case studies. One of these case studies was the making of a presenta-tion of a design to possibly interested parties. The other case study was the use of Virtual Reality in the course of a design process. Finally this publication includes the description of some future and anticipated developments. The research problem is mainly posed by the questions regarding the ways in which the design process changes under the influence of, amongst other factors, the 6 technology. Other questions concern the ways in which the interface between a designer and a design system can be made as natural as possible, the way in which a design model can be made as autonomous as possible, and the way in which a representation can be made as realistic as possible. With regard to these the starting points were respectively the use of sensors, behaviour characteristics and illumination simulations. The development problem is posed by the question regarding the way in which a laboratory setup, in cooperation with a supplier of hardware (Sun Microsystems Nederland BV) and a supplier of software (Autodesk Benelux BV), can be developed. In order to do this use has to be made of their system components, such as workstations and CAD software. Another problem for the development of the laboratory setup is the way in which the project was to be made to lead to presentations and demonstra-tions of 6 technology which was still not yet generally available. The first case study was the development of a 6 presentation of a housing project. This presentation was in the first instance intended for people who had an interest in the project. In addition, naturally, people who really only had an interest in Virtual Reality itself also attended. The presentation was announced as being a first Virtual Open House. Each interested party could wander through the 3D design model and move the furniture. In the course of this case study consideration was above all given to the relationships between the interfaces between the user and the system, the level of detail of the model and the speed of the representation. The second case study was the use of Virtual Reality during a design process. The system is used for the evaluation of visibility and safety aspects of another housing project. The use of the system was initially only intended for the designer and the principal. At the end of the process different design modifications were effected in accordance with their evaluations of the design. After that the system was also used for internal presentations of the applications as well as of the technology. The problem which played a role in the course of these studies was in the first instance a design problem and in the second in-stance a technical problem.

title	Form and Performance in Intelligent CAAD Systems for Early Stages in Solar Design Building
source	Technion, Faculty of Architecture and Town Planing, Haifa
summary	Great care should be taken at the initial design stages to determine the principles and solution schemes for climate and energy-conscious buildings. The present study deals with supporting the designer's efforts at the early stages to lay down the appropriate principles for a conceptual and geometric design of energy-preserving buildings, which are also thermally comfortable and adapted to local climatic conditions. For years, especially during the last decade, important data concerning climate-conscious construction has been compiled, but the information has not been utilized by designers, due to its inaccessibility. It is significant, though, that solutions based on this knowledge could be found and assessed at the preliminary design steps. A correct climate-conscious design conceived at the initial stages may guarantee that during later phases of the project's development no problems calling for essential and drastic changes in the basic design will crop up. The meaning of such changes at later stages may require sometimes a redesigning of the entire project. It is vital, therefore, to understand at the pre-conceptual phase, what are the correct climatic-solar design strategies which satisfy the requirements of the local conditions, and enable the attainment of thermal comfort conditions, while consuming the least possible energy. The present study proposes a computer-aided passive solar design system (PASYS) which enables the handling of entire designing process, and its general, conceptual aspects, as well as the preliminary designing steps and their particular, practical aspects. The system is based both on a knowledge base which stores the existing information concerning solar-climatic construction in the form of rules of thumb, and on precise procedural models which enable finding solutions suited to the local climatic conditions. The proposed system is an intelligent CAAD system which equips the designer who is aware of the constraints of climate and energy, with a tool to achieve a better design. PASYS was developed as a universal system to deal with the various activities involved in the initial – pre-conceptual and conceptual - design stages. The system supports the following design activities of each stage of this kind: analysis, synthesis, documentation, assessment and decision making. It is capable of analyzing given conditions, thus helping the designer understand which are the significant preliminary design stages that have a bearing on thermal comfort conditions in a given climate. The system is also capable of proposing solutions corresponding with the particular design phase, and assess their adequacy. These solutions take into account the constraints determined both by the designer and by the system itself, owing to the knowledge base it contains. The system can also document the various solutions that have been found and selected, so that may be further developed at later stages. This documentation is carried out by a graphic interface, developed as part of the system, as well as by an interface devised for existing CAD software. This study highlights the interaction between form and performance. The system is able to assess the performance of a proposed design by considering a given geometry (form), or viceversa, it is able to recommend a solution that can deliver desired and required performances. The study comprises three parts: (a.) Development of the conceptual model of a knowledge based design process. (b.) Further development of the initial stages of the afore mentioned process, including the pre-conceptual and conceptual stages. (c.) Demonstration of the mode of work with the PASYS system. // The first part of the study deals with the definition of the design process, the definition of the various design steps and their characteristics, and the definition of the activities involved in each design step. This part of the work also presents the kinds of knowledge bases affecting the design process, and shows how this knowledge is an inseparable part of the design process. The second part deals with the development of the initial design stages - the pre-conceptual and the conceptual - which are based on knowledge. This part also contains compiled knowledge that is relevant to the design stage, and a knowledge storage and retrieval method that was developed so as to make the knowledge available and accessible on demand. This part further presents precise procedural methods, developed to find solutions adapted to the specific given conditions, and to precisely assess the performance of the proposed solution. A case in point is the module of the SHADING system which enables a precise assessment of the mutual shading of buildings, and an examination of the exposure of the southern elevation to the sun, which is necessary in order to determine the effective solar absorption area in a proposed project in given environment conditions. The third part of the study demonstrates the solar-climatic design process put into action and supported by the system that was developed. This system enables the designer, even at the preliminary design stages, to determine which properties relating to local climatic conditions he will introduce into the building. This important, seemingly natural act, is usually performed during more advanced stages, when it might generate significant changes in the design, at a juncture when changes are hard to make. A PASYS-aided design environment ensures that from the beginning of the designing process, the project will be designed correctly and efficiently as far as energy is concerned.

title	An Investigation of the Concept of Designer Style and its Relevance to The Design of CAD Systems
doi	https://doi.org/10.52842/conf.ecaade.1994.x.t0t
source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 213
summary	Underlying the notion of style is the basic premise that all designers are not the same and that the manner in which any designer works through a design problem towards a proposed solution may be qualitatively different from other designers. If, through this work, this is shown to be the case and the concept of designer style can be meaningfully discussed then any model of the design process and any system or product relating to this model must allow for such variations at the level of the group or individual. This is the starting point of this investigation of the concept of designer styles.

title	SEED: A Software Environment to Support the Early Phases in Building Design
source	Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary	The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title	Computer Aided Urban Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The product of the Urban Design process in the public sector in the UK is usually a briefing document of some kind which communicates design ideas in outline both to the lay public and to private developers. The problem with briefing effectively is that outline expression of ideas does not provide a strong basis for negotiation with developers; the temptation therefore is to work up one proposal in detail and to present it as the only option. This type of prescriptive briefing may be successful in situations where the public body has control over the land, the economy is buoyant and the site has a simple context. Its problems are that it is labour intensive, so some areas are covered in detail, others not at all; it is seen as restrictive by developers, so may create a climate of conflict rather than certainty; it is not responsive to change; it covers specific sites thoroughly but does not deal well with large, complex areas; on large sites it tends towards a homogeneous environment whereas the nature of towns and cities is pluralistic and heterogeneous; it confines the Urban Designer to site specific work rather than allowing concentration on the whole urban system. Urban Designers at the London Docklands Development Corporation felt that CAD might present some answers to these problems in facilitating an iterative, interactive briefing process which could respond quickly to change; whereby varying options for development could be investigated fully but quickly and resource-efficiently; which could be used to communicate design ideas effectively to non-professionals; which could help to make negotiation with developers more effective, less confrontational; which could deal with large, complex sites effectively. The idea was that a piece of city could be modeled on the computer and an urban design study would then be carried out on it which would test varying options for development, resulting in an outline, but three dimensional, model for an area which could be used in three ways: as a briefing tool, as part of a marketing exercise and as a tool to aid effective negotiation and consultation at the planning stage. A pilot project was carried out on a set of development sites at East India Dock and, following the success of this, a full study was carried at Surrey Quays Centre. The paper describes these projects and discusses both their products and their effect on the developmentprocess as aids in decision making.

title	The Animation of Dynamic Architecture
doi	https://doi.org/10.52842/conf.ecaade.1994.x.q6a
source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 233
summary	The most valuable resource in education is student time and the greatest asset is the ingenuity of student minds. CAD technology now offers enormous potential to education, but limitations in time and funding, prevent its use to the extent possible within practice. Therefore, after dealing with 'awareness', 'attitude' and 'limited applications', our most important role in education is to encourage innovation. The third year of the honours option course at De Montfort University takes this as its theme and challenges students to explore and exploit innovative applications. One particular area of development has been exploring the dynamic aspects of architectural design which go much further than the well-established 'fly-through' sequences. A great deal of architectural design and design development depends upon dynamic issues which range from movement joints to construction sequence. A visual understanding of these dynamic issues drawn from appropriate computer animations can now be an effective factor in design.

title	REAL SCALE MODEL VS. COMPUTER GENERATED MODEL
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	Advances in electronic design and communication are already reshaping the way architecture is done. The development of more sophisticated and user-friendly Computer Aided Design (CAD) software and of cheaper and more powerful hardware is making computers more and more accessible to architects, planners and designers. These professionals are not only using them as a drafting tool but also as a instrument for visualization. Designers are "building" digital models of their designs and producing photo-like renderings of spaces that do not exist in the dimensional world. The problem resides in how realistic these Computer Generated Models (CGM) are. Moss & Banks (1958) considered realism “the capacity to reproduce as exactly as possible the object of study without actually using it”. He considers that realism depends on: 1)The number of elements that are reproduced; 2) The quality of those elements; 3) The similarity of replication and 4) Replication of the situation. CGM respond well to these considerations, they can be very realistic. But, are they capable of reproducing the same impressions on people as a real space? Research has debated about the problems of the mode of representation and its influence on the judgement which is made. Wools (1970), Lau (1970) and Canter, Benyon & West (1973) have demonstrated that the perception of a space is influenced by the mode of presentation. CGM are two-dimensional representations of three-dimensional space. Canter (1973) considers the three-dimensionality of the stimuli as crucial for its perception. So, can a CGM afford as much as a three-dimensional model? The “Laboratorio de Experimentacion Espacial” (LEE) has been concerned with the problem of reality of the models used by architects. We have studied the degree in which models can be used as reliable and representative of real situations analyzing the Ecological Validity of several of them, specially the Real-Scale Model (Abadi & Cavallin, 1994). This kind of model has been found to be ecologically valid to represent real space. This research has two objectives: 1) to study the Ecological Validity of a Computer Generated Model; and 2) compare it with the Ecological Validity of a Real Scale Model in representing a real space.

title	Computer-aided extraction of morphological information from architectural drawings
source	University of Michigan
summary	Along with the popularization of Computer-Aided Design (CAD), it has been becoming increasingly necessary and desirable for a computer to recognize engineering drawings and diagrams. Methods exist for inputting and recognizing such engineering drawings and diagrams. This is primarily because they are drawn to conform to specific standards. In contrast, architectural drawings are not prepared in accordance to existing standards. Hence, the problem of reading, recognizing, and extracting morphological information from them automatically remains unsolved. It is this problem that this study focuses on. The research undertaken by this author has three distinct but interrelated objectives. The first objective is to design, implement, and test a computer-based framework which allows its user to extract automatically the geometric and/or architectural structures of a two-dimensional plan. The second objective entails designing, implementing, and testing a computer-based framework which may be employed to compare the geometric and/or architectural structures of individual plans or classes of such plans. The third objective is to integrate the two aforementioned frameworks. Computer vision techniques are used to investigate, analyze, and compare plans of buildings from a morphological standpoint. Such techniques can contribute toward detecting differences or similarities between individual plans. Their ability to search for, combine, and compare morphological information is both parsimonious and effective. Predicated on the assumption that designers derive knowledge from past solutions to form-making problems, this study focuses on the methods by which the morphological information which is contained in building plans can be extracted automatically and entered in a knowledge base. Conceptually, this is part of a larger project which entails investigating how knowledge can be incorporated in a CAD system in a manner which aids and supports the form-making process. Conceivably, the approach of this work is, wholly or partially, applicable to the problem of extracting useful information from graphic representations used in a variety of disciplines (e.g., engineering).

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 ‚Äúgingerbread houses‚Äù, 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	Residential Comfort as a Tool for the Design and Evaluation of Dwellings
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The term comfort plays a not inconsiderable role in scientific housing research, for example as a predictor of household energy behaviour and of residential satisfaction. Nevertheless, its meaning is mostly ill-defined and it is unclear which properties of the dwelling are associated with the concept. In an exploratory study the meaning and structure of comfort were established on the basis of an etymological analysis, interviews with occupants and experts, an extensive review of the literature and a survey of 500 respondents in the Netherlands. It is shown that residential comfort is a useful and meaningful concept in housing research. It can be regarded as a variable which represents the totality of properties of a dwelling which are important for the well-being of occupants, including its social and psychological aspects. The structure of comfort is captured in a model that can be used in the designing process and the evaluation of dwellings. The model enables an organized overview of the needs of (intended) groups of occupant, of sub-fields of comfort (e.g. sub-properties of the dwelling) associated with these needs and of possible housing characteristics that are necessary for the presence of the sub-fields. The scheme of analysis appears to be a good instrument for the construction of comparable models for other types of building.

title	Post Occupancy Evaluation as a Strategy to Develop an Improved Work Environment
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	A post-occupancy evaluation is a formal way of finding out whether a recently occupied, remodelled, or built environment is performing, as was intended in its programming or design, and a term which has been developed in the professional field in the United States over the last 20 years. The Scandinavian approach to the same question has emphasised surfacing the values of the users of the work environment as a tool for a more comprehensive approach to space planning and design. A recent case-study of the Taubman Building at Harvard University's John F. Kennedy School of Government was aimed at blending the two strategies for evaluation, defined postoccupancy evaluation as a dialogue with the client, as a process to help the client reflect on spatial and technological improvements, or alternate strategies for organisational locations in buildings, and offers an interesting example of a possible future direction for POE's. Sheila Sheridan, Director of Facilities and Services at the Kennedy School, commissioned the case-study, and has been using it result in her daily work. Jacqueline Vischer, who has developed a survey of seven key dimensions of work-place comfort for commercial office buildings throughout eastern North America, and Turid Horgen, who has developed tools for participatory environmental evaluation and programming, widely used in Scandinavia, carried out the study and facilitated the evaluation process. The study is also done in the context of the ongoing research on these issues in the design Inquiry Group at the School of Architecture and Planning at MIT, which is involved in a larger program for developing strategies and tools for more effective programming and management of corporate space. This research defines the workplace environment as the interaction between four dimensions: space, technology, organisation and finance. Our approach is to integrate programming and evaluation with organisational planning and organisational transformation.Post occupancy evaluation is seen as a way to inform the client about his organisational culture as he manages the fit between a facility and its uses, and as one of several tools to bridge the frameworks and viewpoints and the many "languages" which are brought into the decision making process of designing the built environment.

title	The Reflective Eye: Visual Reasoning in the Sketch
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Despite recent advances in our understanding of design thinking, we still lack a comprehensive theoretical approach to cognitive processes in design and particularly to visual reasoning. Of scientific interest in its own right, understanding non-verbal reasoning is also relevant to a wide range of subjects in the area of visual data resources for designers. This paper presents research into visual reasoning through the study of cognitive acts and processes associated with design drawing. Employing case studies in the design sketch, a vocabulary is defined for describing phenomena of visual reasoning in design as they are revealed in the sketch. Classes of reasoning processes are proposed as strings of graphic acts of state transformation. A theoretical schema is developed which relates the individual act of visual reasoning manifested in the sketch, of sketch sequences, with larger global cognitive phenomena such as analogical or associative reasoning in design. Based upon this schema, a symbol system for these acts and processes is proposed as a coding technique in the observation, analysis and recording of non-verbal processes in design.

title	Why Architects Draw

summary	For nearly twenty years Edward Robbins, an anthropologist, has been studying and writing about the system of architectural education and practice in the United States and abroad. In this book he examines the social uses of architectural drawing: how drawing acts to direct both the conception and the production of architecture; how it helps architects set an agenda, define what is important about a design, and communicate with their colleagues and clients; and how it embodies claims about the architect's role, status, and authority. The centerpiece of Robbins's provocative investigation consists of case study narratives based on interviews with nine architects, a developer-architect, and an architectural engineer. The narratives are illustrated by the architects' drawings from projects in Japan, England, Italy, Germany, Spain, Portugal, and the United States, from conception through realization. Included are orthographic and axonometric projections, perspectives, elevations, plans, sections, working drawings, sketches, schematics, construction, and finished drawings. Drawings and interviews with: Edward Cullinan, Spencer de Grey, Jorge Silvetti, Renzo Piano, Alvaro Siza, John Young, Itsuko Hasegawa, William Pedersen, Rafael Moneo, Rod Hackney, Peter Rice.

title	Spatial Schemata and Design Competence: A Case of Beginning Designers
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In the course of learning professional skills in architectural design, students will develop, usually with the help of instructors, certain ways of analyzing spatial relations. Such spatial schemes are considered critical means to the comprehension of the graphical representations of spaces, and therefore schemes of different kind will have different effects on design performance. This study intends to explore this issue. Three sets of experiments are conducted to test our working hypotheses as stated as follows: (i) to reproduce a plane graphic requires knowledge and skills different from those to recognize; (ii) some schemes are more effective than others in reproducing plane graphics; (iii) the kind of schemes that can effectively reproducing given forms (in plane graphics) can also have positive effects on design capabilities. It is interesting to further differenti-ate the kinds of schemes and their power as design tools. All these experiments employ three kinds of spatial schemes: the categorical, the referential, and the hierarchical from the results we can reach the following conclusions: (i) reconstruction is a different mental activity from recognition which is mainly a comparison between the input data and the known characteristics reconstruction relies more on the structured relations among data that should be established in the course of recognition. Therefore, effective cognition is a part of design competence; (ii) categori-cal schema is found most effective in recognition test. The quality of this type has to do with the quality of its contents. Referential schema can effectively relate elements to one another and to the context in which they are located. This schema contributes to the quality of spatial compositions. Hierarchical schemata are more general that can help identify dependent relations among elements, and therefore reduce the complexity. Conceivably this can increase the efficiency of problem-solving in design.

title	The comparison of animation, virtual reality, and scenario scripting in design process

summary	Design media is a fundamental tool, which can incubate concrete ideas from ambiguous concepts. Evolved from freehand sketches, physical models to computerized drafting, modeling (Dave, 2000), animations (Woo, et al., 1999), and virtual reality (Chiu, 1999; Klercker, 1999; Emdanat, 1999), different media are used to communicate to designers or users with different conceptual levels¡@during the design process. Extensively employed in design process, physical models help designers in managing forms and spaces more precisely and more freely (Millon, 1994; Liu, 1996).Computerized drafting, models, animations, and VR have gradually replaced conventional media, freehand sketches and physical models. Diversely used in the design process, computerized media allow designers to handle more divergent levels of space than conventional media do. The rapid emergence of computers in design process has ushered in efforts to the visual impact of this media, particularly (Rahman, 1992). He also emphasized the use of computerized media: modeling and animations. Moreover, based on Rahman's study, Bai and Liu (1998) applied a new design media¡Xvirtual reality, to the design process. In doing so, they proposed an evaluation process to examine the visual impact of this new media in the design process. That same investigation pointed towards the facilitative role of the computerized media in enhancing topical comprehension, concept realization, and development of ideas.Computer technology fosters the growth of emerging media. A new computerized media, scenario scripting (Sasada, 2000; Jozen, 2000), markedly enhances computer animations and, in doing so, positively impacts design processes. For the three latest media, i.e., computerized animation, virtual reality, and scenario scripting, the following question arises: What role does visual impact play in different design phases of these media. Moreover, what is the origin of such an impact? Furthermore, what are the similarities and variances of computing techniques, principles of interaction, and practical applications among these computerized media?This study investigates the similarities and variances among computing techniques, interacting principles, and their applications in the above three media. Different computerized media in the design process are also adopted to explore related phenomenon by using these three media in two projects. First, a renewal planning project of the old district of Hsinchu City is inspected, in which animations and scenario scripting are used. Second, the renewal project is compared with a progressive design project for the Hsinchu Digital Museum, as designed by Peter Eisenman. Finally, similarity and variance among these computerized media are discussed.This study also examines the visual impact of these three computerized media in the design process. In computerized animation, although other designers can realize the spatial concept in design, users cannot fully comprehend the concept. On the other hand, other media such as virtual reality and scenario scripting enable users to more directly comprehend what the designer's presentation.Future studies should more closely examine how these three media impact the design process. This study not only provides further insight into the fundamental characteristics of the three computerized media discussed herein, but also enables designers to adopt different media in the design stages. Both designers and users can more fully understand design-related concepts.

title	Solving design problems by computational exploration
source	J. S. Gero and E. Tyugu (eds), Formal Design Methods for CAD, NorthHolland, Amsterdam, pp. 249-270
summary	Most real-world problems, especially design problems, are ill-structured, but formal approaches to problem-solving in AI have only really made progress into techniques for solving well-structured problems. Nevertheless, such research contains clues which illuminate the way towards formal approaches to solving ill-structured problems. This paper presents the foundations of an approach towards developing a better computational understanding of ill-structured problems and how to solve them computationally, with the eventual aim of giving AI problems a much greater and more useful role in the design process. The main issues which come up in this endeavour are the notions of different kinds of ill-structuredness, and the meaning of a 'solution' to an ill-structured (and hence possibly insoluble) problem. Some basic algorithmic recipes are proposed for dealing with the main kinds of ill-structuredness, and the initial design of a general computational technique which deals with general ill-structuredness is discussed.

title	Sketch-Trigger: A Specification for a Form Generator and Design Analysis Toolbox for Architectural Sketching
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In order to develop design and decision support techniques in the early sketch design phases, weshould (1) experience and (2) observe real behaviour in practice, (3) transform observations intoideas for improvement, (4) develop behaviour models to explain the sketch design activities and(5) to evaluate between the proposals, (6) decide between the alternatives, (7) implement theselected option in a supporting tool. Our paper reports about the results of step 3 in particular inthe first phase of a Ph D project, started this year. Our main objective is to amplify the effects ofthe sketch as a very effective instrument to generate original forms and to stimulate the mind to discover new shapes and meanings in the roughly sketched patterns. Instead of considering the sketch only as a representation of what the designer has in mind as is usually assumed in CAD systems, we see sketching as form activation. Thus, we want also to offer triggering images to spark off the imagination of the designer while generating images which are practically impossibleto create by hand and certainly not at short notice. The main improvement proposed is the use of an evolutionary form breeding system: one or more sketched parent images (either ready-made'partis' or basic schemes drafted by the designer) presented in the centre of the screen, will generate surrounding mutated children as defined at random but constrained by default or customization of the available transformations. By selecting one or more children a next generation will be produced in the same way. At all times the designer can introduce or reduce constraints. To complete the usually offered 'classical' symmetrical, spatial and logical operations,we want to introduce dis-functional operations like dislocation, explosion, deformation, anti-logic etc, in short all kinds of antagonistic operations, among them the transformations applied indeconstructionist and post-modern design. Our expectation is that these operations will correspond roughly to the 'move' pertaining to a design entity as the operational unit most appropriate for design behaviour research, in particular the analysis of the chunking and parsing behaviour of the designer. The applicability of the 'move' approach has been shown experimentally by Habraken and others. Goldschmidt has abandoned the usual typology approach of protocolanalysis based on moves and concentrated on the linking of moves, but has been hampered by the lack of a good representational instrument. This brings us to the representation of moves and linkages as a research instrument. The 'linkograph' approach as proposed by Goldschmidt is a first step towards a graphical representation of the designers associative reasoning mode, necessary for tracking the heuristics of designers at the most basic level, but its practical implementation remained as yet incredibly laborious. What is proposed here is an instrument and approach which makes such registration and analysis possible within a structured software environment.

summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

summary	Computer-aided-design (CAD) systems are now used to design all kinds of artifacts, from jet fighters to works of art. A major challenge in the design of a CAD system itself is the user interface (UI). Developing the UI to a CAD system raises myriad questions about input devices and techniques, display devices and techniques, and the details of the dialogue that relates the two. But these questions are ancillary to one central question: what is the fundamental nature of the interaction between human and computer in the design process supported by the CAD system? Is the design activity essentially manual, with the computer playing the role of passive tool, like a pen or paintbrush? Or is the computer augmenting the human designer by actively restricting available design choices, or by playing the role of critic or "improver"? Or maybe the interaction paradigm is one of "interactive evolution," in which the computer is responsible for generating design alternatives, with the human merely choosing among choices suggested by the machine. Or perhaps the computer performs the design process completely automatically, with a final acceptance check being the only human contribution? The panelists will describe these different paradigms for human-computer cooperation in a set of related CAD systems and prototypes and discuss the conditions under which each paradigm might be most useful.
