summary The dual function of the Environmental Design Assistant which we have developed is to act firstly as a teaching aid and secondly as a design aid. In terms of it's role as a design assistant it is similar in nature to the application described by Papamichael, K, in Novitski, B. J. (1993). However, the work described here forms part of an overall strategy to develop a user friendly design assistant across the spectrum of Architectural design disciplines: this is one particular strand of the project. One aim embodied in the development of the environmental design assistant has been the pragmatic one of the production and refining of a tool to perform environmental assessments of buildings in accordance with the British recommendations made in BREEAM (Building Research Establishment Energy Assessment Method). In this respect the assistant allows for the consequences of design decisions to be readily assessed and then for those decisions to be modified. The Assistant has undergone a series of refinements to make it more user-friendly, efficient and appropriate as an Architectural design aid; and this has been the second aim of the project. The project has acted as a vehicle for the application of design principles applied to the presentation, information structuring and navigation associated with Hypermedia and Multimedia products. We are applying the kind of good design principles which have been summarised well by Schulmeister, R. (1994). These principles include Ariadne's Thread (paths for navigation), Lost in Hyperspace (backward navigation), More-than-browsing (interaction) and Tutoring (providing feedback to the user). Adoption of such principles is, we believe, essential in order to realise the potential of Hypermedia tools. The principal development tool for the work has been SuperCard. This has been used in conjunction with a range of other software including ArchiCad and Intellidraw and a range of image grabbing devices.

title Contextual Hypermedia in the Design Studio
source [eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi https://doi.org/10.52842/conf.ecaade.1993.x.i7f
summary The focus of this paper is on the development and use of hypermedia applications for the presentation of design studio projects, based upon the author's own recent experience of teaching CAD at both undergraduate and postgraduate level. The contention of this paper is that this activity cannot be reduced to routine Hypercard stack development. Instead, the development of applications in this area need to give support to the expression of the design-theoretical issues that are central to the presentation of any design studio project, by exploiting the many issues of concern that are emerging from the field of human- computer interaction (HCI) The hypermedia application i.e. in this case design-theoretical views of a design project, will inevitably influence the specification of a user-interface, and hence the presentation and appearance of the design project. This paper will investigate the extent to which the interface can be separated out from the application and the converse issue namely, whether non-contextual hypermedia environments restrict design applications.

title Some Phenomena of Spatial Characteristics of Cyberspace
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 "Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

title Applying Visual Design: Trade Secrets for Elegant Interfaces Tutorials
source Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems -- Adjunct Proceedings 1993 p. 230
summary Objective: This tutorial is designed to increase the participant's awareness of visual and aesthetic issues and provide practical techniques (not guidelines) for achieving elegant user interfaces, information displays, and data visualisations. The emphasis is on avoiding a number of mistakes seen repeatedly in commercial products. Content: This tutorial will focus on the core competencies or "tricks of the trade" that all visual designers internalise as part of their basic training. The tutorial is organised not along the traditional graphic design specialisations, such as typography or colour, but according to the design goals and familiar problems of real-world product development. Specific content areas will include elegance and simplicity; scale, contrast and proportion; organisation and visual structure; module and programme; image and representation; and style. The communication-oriented design aesthetic seen in graphic design, industrial design, and architecture can be applied very successfully to graphical user interfaces, data displays, and multimedia. Design rules provided will be illustrated with extensive visual examples drawn from the international design communities as well as from the HCI domain.

title The Evolution of an Interface for Choreographers Evolving Design
source Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems 1993 pp. 115-122
summary This paper describes the evolution of the interface to Life Forms, a compositional tool for the creation of dance choreography, and highlights some of the important lessons we have learned during a six year design and implementation period. The lessons learned can be grouped into two categories: 1) Process, and 2) Architecture of the Interface. Our goal in developing a tool for choreography has been to provide computer-based creative design support for the conception and development of dance. The evolution was driven by feedback from the choreographers and users who were members of the development team, combined with our knowledge of current thinking on design and composition. Although the interface evolved in a relatively unconstrained way, the resulting system has many of the features that theoretical discussion in human interface design has projected as necessary. The Life Forms interface has evolved incrementally with one major discontinuity where adoption of a new compositional primitive required a completely new version. The choreography and composition of a dance is a complex synthesis task which has much in common with design. Thus, the lessons learned here are applicable to the development of interfaces to such applications as computer aided design.

summary v Knowledge is commonly socially constructed, through collaborative efforts... v Intelligence may also be distributed for use in designed artifacts as diverse as physical tools, representations such as diagrams, and computer-user interfaces to complex tasks. v Leont'ev 1978 for activity theory that argues forcibly for the centrality of people-in-action, activity systems, as units of analysis for deepening our understanding of thinking. v Intelligence is distributed: the resources that shape and enable activity are distributed across people, environments, and situations. v Intelligence is accomplished rather than possessed. v Affordance refers to the perceived and actual properties of a thing, primarily those functional properties that determine how the thing could possibly be used. v Norman 1988 on design and psychology - the psychology of everyday things" v We deploy effort-saving strategies in recognition of their cognitive economy and diminished opportunity for error. v The affordances of artifacts may be more or less difficult to convey to novice users of these artifacts in the activities to which they contribute distributed intelligence. v Starts with Norman's seven stages of action Ø Forming a goal; an intention § Task desire - clear goal and intention - an action and a means § Mapping desire - unable to map goal back to action § Circumstantial desire - no specific goal or intention - opportunistic approach to potential new goal § Habitual desire - familiar course of action - rapidly cycle all seven stages of action v Differentiates inscriptional systems from representational or symbol systems because inscriptional systems are completely external, while representational or symbol systems have been used in cognitive science as mental constructs. v The situated properties of everyday cognition are highly inventive in exploiting features of the physical and social situation as resources for performing a task, thereby avoiding the need for mental symbol manipulations unless they are required by that task. v Explicit recognition of the intelligence represented and representable in design, specifically in designed artifacts that play important roles in human activities. v Once intelligence is designed into the affordances properties of artifacts, it both guides and constrains the likely contributions of that artifact to distributed intelligence in activity. v Culturally valued designs for distributed intelligence will change over time, especially as new technology becomes associated with a task domain. v If we treat distributed intelligence in action as the scientific unit of analysis for research and theory on learning and reasoning... Ø What is distributed? Ø What constraints govern the dynamics of such distributions in different time scales? Ø Through what reconfigurations of distributed intelligence might the performance of an activity system improve over time? v Intelligence is manifest in activity and distributed in nature. v Intelligent activities ...in the real world... are often collaborative, depend on resources beyond an individual's long-term memory, and require the use of information-handling tools... v Wartofsky 1979 - the artifact is to cultural evolution what the gene is to biological evolution - the vehicle of information across generations. v Systems of activity - involving persons, environment, tools - become the locus of developmental investigation. v Disagrees with Salomon et al.'s entity-oriented approach - a language of containers holding things. v Human cognition aspires to efficiency in distributing intelligence - across individuals, environment, external symbolic representations, tools, and artifacts - as a means of coping with the complexity of activities we often cal "mental."

summary The Sagrada Familia Church has appointed two groups of consultants to assist the translation of Gaudi's 1:10 scaled models of the nave into coherent information from which to build. One team has been undertaking the static analysis of the nave roof vault structure and the other the study of the complexities of Gaudi's composition in order to provide full-scale production templates and models for the walls. Both teams had begun using the same basic CAD package and both have had to move onto high-end and very expensive solid-modelling software normally used by mechanical engineers and vehicle designers. Both groups are collaborating together with different accents despite an improbable geographical separation. The original problem, one of intersecting ruled-surfaces accurately to reflect the geometries of the surviving fragments of the original models, has led to surprising possibilities which were not anticipated at the outset. Currently the potential of parametric variation and associative geometries are being investigated as a mirror for some of the intuitive design process and finite element analysis is being considered as a means of interactively analysing the structural implications for each study. The software being used also has a powerful ray-tracing module; rather than being simply a tool to produce eye-catching 'realistic' renderings it has proved to be invaluable in allowing the computer user to understand the spatial complexities of the components being studied. This paper discusses the merits of an architecture so demanding (despite having been designed at the beginning of this century) that it requires the most costly equipment in today's market and it will consider the proposition that in ordinary circumstances, an architecture too complex to be described using basic CAD tools is an architecture beyond our reach. The interdisciplinary nature of the diverse and powerful modules within the software referred to will be used to contest this proposition using the presence of both teams in schools of architecture as evidence.

summary Simulating the development and the image of architecture and urban design means to show how the environment of the future and the living conditions could develop. At the same time it is part of our task to explain our work to local people and to the public and to passion skills in methods, instruments and knowledge in planning to the next generation of architects, planners and last but not least to discuss and to renew them once more for ourselves. Our aim was also to reflect what we have done since starting the look through the key-hole of endoscopy. Meanwhile this look has been completed since the beginnings in 1993 much more by computer and monitor. It is not the question to take the endoscope or the computer as a methodical and instrumental approach. Nowadays we normally decide to take the endoscope and the computer. In preparing the conference and the workshop we thought that this should now also be the moment not only to inform each other and the participants on methods, tools and best practices in simulating and designing the environment but also to focus on the social and human consequences of perception, movement and use the present urban spaces and the urban space in future. So we proposed the theme “MOTION, E-MOTION and URBAN SPACE” and we invited a scientific expert in experimental psychology to give us some serious reflections and one or another hint on our research themes and methods. The contributions and discussions in the conference showed that the proposal has not only been accepted but has also been completed and enriched especially concerning the theme urban space, it’s processes of usage and it‘s atmosphere. Also in the themes of endoscopy and the research on modelling urban spaces and architecture, meanwhile nearly “traditional” ones, remarkable results were presented and discussed. A very important point of contributions and the following discussions was how to present our subjects to the interested public and to improve our own internal exchange. An object could be to enforce the research tasks in researching together even more.

title Parallel Modeling: Addressing the Issues of Creative Designing in CAD Environments II. Special Applications
source Proceedings of the Fifth International Conference on Human-Computer Interaction 1993 v.1 pp. 249-254
summary We postulate that Industrial Designers, in general, solve a given problem by generating a series of proposed solutions to that problem, each proposal, in theory, helps the designer to converge on the ideal solution. Any number of solutions may be under continuous development at any one time and any previous solutions should always be available for appraisal and viewing. The single modeling environment provided in traditional Computer Aided Design (CAD) systems does not support this practice. Thus, CAD systems are primarily used to address the final phases of the design process, such as analysis, visualisation and detailing. This is surely not utilising the full potential of such a powerful design tool. In an attempt to develop a less restrictive working practice for CAD users, we consider a parallel modeling approach. This solution allows the simultaneous development, design and review of a number of computer based solutions.

summary The work described here represents an attempt to devise CAD techniques appropriate to the apparel industry. An integrated approach is outlined which provides a greater justification for CAD, other than the ability to produce a single image of a design concept. In addition, high level tools are described which enable 3D design specifications to be evolved without exhaustive dimensional input.

title Recognizing Emergent Subshapes in Design Problem Solving: A Connectionist Investigation
source Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 131-139
doi https://doi.org/10.52842/conf.acadia.1993.131
summary Human problem-solving behavior has been modelled as a search through the space as defined as problem states, within which earlier states move to subsequent ones by applying rules in the human mind until the goal state is found. This cognitive model of problem-solving has been broadly accepted and has become dominant in both cognitive psychology and artificial intelligence (AI). In the field of computeraided architectural design (CAAD), search models are also widely used for solving design problems, although various foci of design knowledge are differently represented by shape grammars, graphs, and knowledge-based systems using predicate logic for different purports.

In design search, design evolves from one state to another by exhaustively or heuristically applying proper rules. Each rule application involves, first, pattern-matching the antecedent of a rule to the current state and, second, transforming the matched portion of that state into the consequence of the rule. However pattern-matching techniques of current CAAD systems are still limited. In current CAAD systems, only those two squares can be dealt with by patternmatching for further development. However, a human designer can effortlessly recognize not only those two but other emergent subshapes, for example a smaller square in the middle where the two squares overlap and two L-shapes in the corners. Therefore a human designer can thoroughly deliberate all these alternatives before making a decision. In other words, human designer is capable of restructuring shapes in terms of emergent subshapes in any step of designing.

doi https://doi.org/10.52842/conf.acadia.1993.077
summary Architects and urban designers are increasingly using computers in their attempt to improve decision making in urban design. Most existing systems emphasize hard data such as statistics, land use data, etc. In recent years with the use of more powerful computers we have seen a greater emphasis on managing visual data. Computer systems are being used to generate urban models and simulations of the various kinds of impact new developments have on the existing cityscape.

This project emphasizes the use of visual data. The purpose of the research has been to develop a computer system for urban designers to use in analyzing urban architectural qualities. Therefore this project focuses on applying traditional methods and theories of urban designers rather than developing new computer techniques.

The traditional methods and theories of urban designers fall within the category which the French theorist Francoise Choay calls Pre-urbanism and Urbanism - the Cultural Model. Theorists within this category include Camillo Sitte, Gordon Cullen, Kevin Lynch, Leon Krier, Aldo Rossi, Michael Trieb, Roger Tranzick and Thiis-Evensen.

This computer system has been developed as a prototype in order to gain experience and knowledge for future development of a large system. Later development will be based upon a vectorized threedimensional model of a whole city using texture mapping and tracing techniques to annotate important architectural features.

The computer system consists of the basic analysis module supplied with a simulation unit and a theory unit. With this analytical tool, analysis is conducted on three different urban scales. The prototype has been developed on the Macintosh computer with SuperCard as the authoring tool.

The computer system was developed as a prototype for Danish Urban Designers and is currently being tested in conjunction with the city of Viborg, Denmark. ( population 55,000). Located in Jutland, Viborg was the capital of Denmark around the year 1000. It now functions as a center for regional government. Viborg was selected as the test site because of its historical core.

summary The application of computer--based technique to support architectural design has often concentrated on matters of representation. Typically, this means computer-aided drafting, and less frequently, computer-aided modeling and visualization. The promise of new computer-based tools to support the process of design has thus far failed to produce any significant tool that has had a widespread impact on the architectural profession. Most developments remain in university based research labs where they are used as teaching instruments in CAD courses or less often in design studios. While there are many reasons for this lack of dissemination, including a reluctance on the part of the architectural profession itself, the primary obstacles deal with difficulties in explicating design knowledge, representing this knowledge in a manner that can be used for design, and providing an intuitive and effective user interface, allowing the designer to easily use the tool for its intended purpose.

This study describes a system that has been developed to address a number of these issues. Based on research findings from the field of Artificial Intelligence which expounds on the need for multiple techniques to represent any complex area of knowledge, we have selected a particular approach that focuses on multiple techniques for design representation. We review this approach in depth by considering its many facets necessary when implementing a knowledge-based system. We then partially test the viability of this approach through a small case study, implementing a knowledge-based system for designing stairs. While this effort only deals with a small part of the total design process, it does explore a number of significant issues facing the development of computer-based design assistants, and suggests several techniques for addressing these concerns.

summary Jaron Lanier is a major spokesperson of our society's hottest new technology: VR or virtual reality. He expressed his faith in the VR movement in this quote which appears in The User's Guide to the New Edge published by Mondo 2000. In its most technical sense, VR has attracted the attention of politicians in Washington who wonder if yet another technology developed in the United States will find its application across the globe in Asia. In its most human element, an entire "cyberpunk movement" has appealed to young minds everywhere as a seemingly safe form of hallucination. As architecture students, educators, and practitioners around the world are becoming attracted to the possibilities of VR technology as an extension of 3D modeling, visualization, and animation, it is appropriate to consider an overview of virtual reality.

In virtual reality a user encounters a computersimulated environment through the use of a physical interface. The user can interact with the environment to the point of becoming a part of the experience, and the experience becomes reality. Natural and

instinctive body movements are translated by the interface into computer commands. The quest for perfection in this human-computer relationship seems to be the essence of virtual reality technology.

To begin to capture the essence of virtual reality without first-hand experience, it is helpful to understand two important terms: presence and immersion. The sense of presence can be defined as the degree to which the user feels a part of the actual environment. The more reality the experience provides, the more presence it has. Immersion can be defined as the degree of other simulation a virtual reality interface provides for the viewer. A highly immersive system might provide more than just visual stimuli; for example, it may additionally provide simulated sound and motion, and simultaneously prevent distractions from being present.

title A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

title A toolset for navigation in virtual environments
source Proceedings of the ACM User Interface Software and Technology, pp.157-165
summary Maintaining knowledge of current position and orientation is frequently a problem for people in virtual environments. In this paper we present a toolset of techniques based on principles of navigation derived from real world analogs. We include a discussion of human and avian navigation behaviors and show how knowledge about them were used to design our tools. We also summarize an informal study we performed to determine how our tools influenced the subjects' navigation behavior. We conclude that principles extracted from real world navigation aids such as maps can be seen to apply in virtual environments.

summary The formulation of design knowledge as concepts, goals and rules cannot be captured in fixed and valid statements. The dynamic modelling of concepts and goals is, on the contrary, part of the design process itself. Tools that effectively support architects in their design should therefore never use predefined mechanisms, but must be definable interactively according to design specifications. We propose the concept of prototypes as a cognitive model to represent and structure design knowledge. Prototypes incorporate an individual view of design in a synthetic and organizational model for a defined area of interest. They actively control and guide design processes in supporting the organizational concepts for solutions. The a+Tool implements these concepts on the basis of a modelling language. It provides a dynamic toolkit and user interface to support design as well as knowledge modelling.

summary There is an essential contradiction between the making of buildings or built environments in a threedimensional modeler and the graphic control of this process. Three-dimensional modeling is a constructive activity, in which solids are assembled as they would be in an actual structure; it benefits the designer. Presentation and documentation, on the other hand, are prescriptive activities that direct some of the construction and all the visualization and criticism of the proposal; they benefit the user and builder.

A building while being designed can be visualized and criticized from its solid model, and the model can take a variety of forms depending on its part): computer-based, drawn in orthographic or perspective projection, constructed of cardboard or wood, or described narratively by means of text, programmatic data, performance model or animation. However, practicing architecture is the process of recording and communicating the decision making process and the contractual obligations that result. In actual practice, in contrast to the designer directed ideal, more participants are brought in sooner at the beginning of a project and with more publicity, which in turn means keeping more, not fewer, records. As the profession evolves, records of the string of design decisions will become more automated, more carefully structured and more retrievable. More buildings will be "tracked" and exposed to review in this way because public environmental sensitivity will improve. The communication between a single designer and his own thoughts will become less and less important.

title A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques

summary Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.
