title Metaphors in Design: An Experiment with a Frame, Two Lines and Two Rectangles

summary The research we will discuss below originated from an attempt to examine the capacity of designers to evaluate an artifact, and to study the feasibility of replicating a designer's moves intended to make an artifact more expressive of a given quality. We will present the results of an interactive computer experiment, first developed at the MIT Design Research Seminar, which is meant to capture the subject’s actions in a simple design task as a series of successive "moves"'. We will propose that designers use metaphors in their interaction with design artifacts and we will argue that the concept of metaphors can lead to a powerful theory of design activity. Finally, we will show how such a theory can drive the project of building a design system.

When trying to understand how designers work, it is tempting to examine design products in order to come up with the principles or norms behind them. The problem with such an approach is that it may lead to a purely syntactical analysis of design artifacts, failing to capture the knowledge of the designer in an explicit way, and ignoring the interaction between the designer and the evolving design. We will present a theory about design activity based on the observation that knowledge is brought into play during a design task by a process of interpretation of the design document. By treating an evolving design in terms of the meanings and rules proper to a given way of seeing, a designer can reduce the complexity of a task by focusing on certain of its aspects, and can manipulate abstract elements in a meaningful way.

title The Intelligent Sketch: Developing a Conceptual Model for a Digital Design Assistant

summary The computer is a relatively new tool in the practice of Architecture. Since its introduction, there has been a desire amongst designers to use this new tool quite early in the design process. However, contrary to this desire, most Architects today use pen and paper in the very early stages of design to sketch. Architects solve problems by thinking visually. One of the most important tools that the Architect has at his disposal in the design process is the hand sketch. This iterative way of testing ideas and informing the design process with images fundamentally directs and aids the architect’s decision making. It has been said (Schön and Wiggins 1992) that sketching is about the reflective conversation designers have with images and ideas conveyed by the act of drawing. It is highly dependent on feedback. This “conversation” is an area worthy of investigation. Understanding this “conversation” is significant to understanding how we might apply the computer to enhance the designer’s ability to capture, manipulate and reflect on ideas during conceptual design. This paper discusses sketching and its relation to design thinking. It explores the conversations that designers engage in with the media they use. This is done through the explanation of a protocol analysis method. Protocol analysis used in the field of psychology, has been used extensively by Eastman et al (starting in the early 70s) as a method to elicit information about design thinking. In the pilot experiment described in this paper, two persons are used. One plays the role of the “hand” while the other is the “mind”- the two elements that are involved in the design “conversation”. This variation on classical protocol analysis sets out to discover how “intelligent” the hand should be to enhance design by reflection. The paper describes the procedures entailed in the pilot experiment and the resulting data. The paper then concludes by discussing future intentions for research and the far reaching possibilities for use of the computer in architectural studio teaching (as teaching aids) as well as a digital design assistant in conceptual design.

title Computers and Design Activities: Their Mediating Role in Engineering Education
source Sociomedia, ed. Edward Barret. MIT Press
summary Sociomedia: With all the new words used to describe electronic communication (multimedia, hypertext, cyberspace, etc.), do we need another one? Edward Barrett thinks we do; hence, he coins the term "sociomedia." It is meant to displace a computing economy in which technicity is hypostasized over sociality. Sociomedia, a compilation of twenty-five articles on the theory, design and practice of educational multimedia and hypermedia, attempts to re-value the communicational face of computing. Value, of course, is "ultimately a social construct." As such, it has everything to do with knowledge, power, education and technology. The projects discussed in this book represent the leading edge of electronic knowledge production in academia (not to mention major funding) and are determining the future of educational media. For these reasons, Sociomedia warrants close inspection. Barrett's introduction sets the tone. For him, designing computer media involves hardwiring a mechanism for the social construction of knowledge (1). He links computing to a process of social and communicative interactivity for constructing and desseminating knowledge. Through a mechanistic mapping of the university as hypercontext (a huge network that includes classrooms as well as services and offices), Barrett models intellectual work in such a way as to avoid "limiting definitions of human nature or human development." Education, then, can remain "where it should be--in the human domain (public and private) of sharing ideas and information through the medium of language." By leaving education in a virtual realm (where we can continue to disagree about its meaning and execution), it remains viral, mutating and contaminating in an intellectually healthy way. He concludes that his mechanistic model, by means of its reductionist approach, preserves value (7). This "value" is the social construction of knowledge. While I support the social orientation of Barrett's argument, discussions of value are related to power. I am not referring to the traditional teacher-student power structure that is supposedly dismantled through cooperative and constructivist learning strategies. The power to be reckoned with in the educational arena is foundational, that which (pre)determines value and the circulation of knowledge. "Since each of you reading this paragraph has a different perspective on the meaning of 'education' or 'learning,' and on the processes involved in 'getting an education,' think of the hybris in trying to capture education in a programmable function, in a displayable object, in a 'teaching machine'" (7). Actually, we must think about that hybris because it is, precisely, what informs teaching machines. Moreover, the basic epistemological premises that give rise to such productions are too often assumed. In the case of instructional design, the episteme of cognitive sciences are often taken for granted. It is ironic that many of the "postmodernists" who support electronic hypertextuality seem to have missed Jacques Derrida's and Michel Foucault's "deconstructions" of the epistemology underpinning cognitive sciences (if not of epistemology itself). Perhaps it is the glitz of the technology that blinds some users (qua developers) to the belief systems operating beneath the surface. Barrett is not guilty of reactionary thinking or politics; he is, in fact, quite in line with much American deconstructive and postmodern thinking. The problem arises in that he leaves open the definitions of "education," "learning" and "getting an education." One cannot engage in the production of new knowledge without orienting its design, production and dissemination, and without negotiating with others' orientations, especially where largescale funding is involved. Notions of human nature and development are structural, even infrastructural, whatever the medium of the teaching machine. Although he addresses some dynamics of power, money and politics when he talks about the recession and its effects on the conference, they are readily visible dynamics of power (3-4). Where does the critical factor of value determination, of power, of who gets what and why, get mapped onto a mechanistic model of learning institutions? Perhaps a mapping of contributors' institutions, of the funding sources for the projects showcased and for participation in the conference, and of the disciplines receiving funding for these sorts of projects would help visualize the configurations of power operative in the rising field of educational multimedia. Questions of power and money notwithstanding, Barrett's introduction sets the social and textual thematics for the collection of essays. His stress on interactivity, on communal knowledge production, on the society of texts, and on media producers and users is carried foward through the other essays, two of which I will discuss. Section I of the book, "Perspectives...," highlights the foundations, uses and possible consequences of multimedia and hypertextuality. The second essay in this section, "Is There a Class in This Text?," plays on the robust exchange surrounding Stanley Fish's book, Is There a Text in This Class?, which presents an attack on authority in reading. The author, John Slatin, has introduced electronic hypertextuality and interaction into his courses. His article maps the transformations in "the content and nature of work, and the workplace itself"-- which, in this case, is not industry but an English poetry class (25). Slatin discovered an increase of productive and cooperative learning in his electronically- mediated classroom. For him, creating knowledge in the electronic classroom involves interaction between students, instructors and course materials through the medium of interactive written discourse. These interactions lead to a new and persistent understanding of the course materials and of the participants' relation to the materials and to one another. The work of the course is to build relationships that, in my view, constitute not only the meaning of individual poems, but poetry itself. The class carries out its work in the continual and usually interactive production of text (31). While I applaud his strategies which dismantle traditional hierarchical structures in academia, the evidence does not convince me that the students know enough to ask important questions or to form a self-directing, learning community. Stanley Fish has not relinquished professing, though he, too, espouses the indeterminancy of the sign. By the fourth week of his course, Slatin's input is, by his own reckoning, reduced to 4% (39). In the transcript of the "controversial" Week 6 exchange on Gertrude Stein--the most disliked poet they were discussing at the time (40)--we see the blind leading the blind. One student parodies Stein for three lines and sums up his input with "I like it." Another, finds Stein's poetry "almost completey [sic] lacking in emotion or any artistic merit" (emphasis added). On what grounds has this student become an arbiter of "artistic merit"? Another student, after admitting being "lost" during the Wallace Steven discussion, talks of having more "respect for Stevens' work than Stein's" and adds that Stein's poetry lacks "conceptual significance[, s]omething which people of varied opinion can intelligently discuss without feeling like total dimwits...." This student has progressed from admitted incomprehension of Stevens' work to imposing her (groundless) respect for his work over Stein's. Then, she exposes her real dislike for Stein's poetry: that she (the student) missed the "conceptual significance" and hence cannot, being a person "of varied opinion," intelligently discuss it "without feeling like [a] total dimwit." Slatin's comment is frightening: "...by this point in the semester students have come to feel increasingly free to challenge the instructor" (41). The students that I have cited are neither thinking critically nor are their preconceptions challenged by student-governed interaction. Thanks to the class format, one student feels self-righteous in her ignorance, and empowered to censure. I believe strongly in student empowerment in the classroom, but only once students have accrued enough knowledge to make informed judgments. Admittedly, Slatin's essay presents only partial data (there are six hundred pages of course transcripts!); still, I wonder how much valuable knowledge and metaknowledge was gained by the students. I also question the extent to which authority and professorial dictature were addressed in this course format. The power structures that make it possible for a college to require such a course, and the choice of texts and pedagogy, were not "on the table." The traditional professorial position may have been displaced, but what took its place?--the authority of consensus with its unidentifiable strong arm, and the faceless reign of software design? Despite Slatin's claim that the students learned about the learning process, there is no evidence (in the article) that the students considered where their attitudes came from, how consensus operates in the construction of knowledge, how power is established and what relationship they have to bureaucratic insitutions. How do we, as teaching professionals, negotiate a balance between an enlightened despotism in education and student-created knowledge? Slatin, and other authors in this book, bring this fundamental question to the fore. There is no definitive answer because the factors involved are ultimately social, and hence, always shifting and reconfiguring. Slatin ends his article with the caveat that computerization can bring about greater estrangement between students, faculty and administration through greater regimentation and control. Of course, it can also "distribute authority and power more widely" (50). Power or authority without a specific face, however, is not necessarily good or just. Shahaf Gal's "Computers and Design Activities: Their Mediating Role in Engineering Education" is found in the second half of the volume, and does not allow for a theory/praxis dichotomy. Gal recounts a brief history of engineering education up to the introduction of Growltiger (GT), a computer-assisted learning aid for design. He demonstrates GT's potential to impact the learning of engineering design by tracking its use by four students in a bridge-building contest. What his text demonstrates clearly is that computers are "inscribing and imaging devices" that add another viewpoint to an on-going dialogue between student, teacher, earlier coursework, and other teaching/learning tools. The less proficient students made a serious error by relying too heavily on the technology, or treating it as a "blueprint provider." They "interacted with GT in a way that trusted the data to represent reality. They did not see their interaction with GT as a negotiation between two knowledge systems" (495). Students who were more thoroughly informed in engineering discourses knew to use the technology as one voice among others--they knew enough not simply to accept the input of the computer as authoritative. The less-advanced students learned a valuable lesson from the competition itself: the fact that their designs were not able to hold up under pressure (literally) brought the fact of their insufficient knowledge crashing down on them (and their bridges). They also had, post factum, several other designs to study, especially the winning one. Although competition and comparison are not good pedagogical strategies for everyone (in this case the competitors had volunteered), at some point what we think we know has to be challenged within the society of discourses to which it belongs. Students need critique in order to learn to push their learning into auto-critique. This is what is lacking in Slatin's discussion and in the writings of other avatars of constructivist, collaborative and computer-mediated pedagogies. Obviously there are differences between instrumental types of knowledge acquisition and discoursive knowledge accumulation. Indeed, I do not promote the teaching of reading, thinking and writing as "skills" per se (then again, Gal's teaching of design is quite discursive, if not dialogic). Nevertheless, the "soft" sciences might benefit from "bridge-building" competitions or the re-institution of some forms of agonia. Not everything agonistic is inhuman agony--the joy of confronting or creating a sound argument supported by defensible evidence, for example. Students need to know that soundbites are not sound arguments despite predictions that electronic writing will be aphoristic rather than periodic. Just because writing and learning can be conceived of hypertextually does not mean that rigor goes the way of the dinosaur. Rigor and hypertextuality are not mutually incompatible. Nor is rigorous thinking and hard intellectual work unpleasurable, although American anti-intellectualism, especially in the mass media, would make it so. At a time when the spurious dogmatics of a Rush Limbaugh and Holocaust revisionist historians circulate "aphoristically" in cyberspace, and at a time when knowledge is becoming increasingly textualized, the role of critical thinking in education will ultimately determine the value(s) of socially constructed knowledge. This volume affords the reader an opportunity to reconsider knowledge, power, and new communications technologies with respect to social dynamics and power relationships.

title A computer-based framework for analyzing and deriving the morphological structure of architectural designs
source University of Michigan
summary An approach to the acquisition and utilization of knowledge about the morphological structure of notable orthogonal building plans and other two-dimensional compositions is formulated and tested. This approach consists of two levels of abstraction within which the analysis and comparison of existing designs and the derivation of new designs can be undertaken systematically and efficiently. Specifically, the morphological structure of orthogonal building plans and other two-dimensional compositions is conceived as a language defined by shape grammar and architectural grammar corresponding to the geometric and spatial structures of the compositions. Lines constitute the shape grammar and walls and columns the architectural grammar. A computer program named ANADER is designed and implemented using the C++ object-oriented language to describe feasible compositions. It is argued that the gap between morphological analysis and synthesis is bridged partially because the proposed framework facilitates systematic comparisons of the morphological structures of two-dimensional orthogonal compositions and provides insight into the form-making process used to derive them. As an analytical system, the framework contributes to the generation of new and the assessment of existing morphological knowledge. Specifically, it is demonstrated that it is feasible to specify an existing architectural design by a set of universal rule schemata and the sequence of their application. As a generative system, the framework allows many of the tasks involved in the derivation of two-dimensional orthogonal compositions to be carried out. As well, it promotes the use of analytical results. In conclusion, it is argued that the proposed computer-based framework will provide the research and the educator with increasing opportunities for addressing persistent architectural questions in new ways. Of particular interest to this author are questions concerning the decision-making activities involved in form- and space-making as well as the description, classification, and derivation of architecutural form and space. It is suggested that, at least in reference to the cases examined, but probably also in reference to many other morphological classes, these and other related questions can be addressed systematically, efficiently, and fruitfully by using the proposed framework.

title ClearBoard: A Seamless Medium for Shared Drawing and Conversation with Eye Contact Systems for Media-Supported Collaboration
source Proceedings of ACM CHI'92 Conference on HumanFactors in Computing Systems 1992 pp. 525-532
summary This paper introduces a novel shared drawing medium called ClearBoard. It realizes (1) a seamless shared drawing space and (2) eye contact to support realtime and remote collaboration by two users. We devised the key metaphor: "talking through and drawing on a transparent glass window" to design ClearBoard. A prototype of ClearBoard is implemented based on the "Drafter-Mirror" architecture. This paper first reviews previous work on shared drawing support to clarify the design goals. We then examine three metaphors that fulfill these goals. The design requirements and the two possible system architectures of ClearBoard are described. Finally, some findings gained through the experimental use of the prototype, including the feature of "gaze awareness", are discussed.

summary This paper addresses new design teaching strategies at an important and traditional university in Istanbul, founded as the Academy of Fine Arts 110 years ago. It will include a short review of design education before the Academy changed into a university, and a description of the present situation with regard to computers. Nearly two years ago, CAAD education was introduced as an elective subject. The students show great interest in CAD; most Turkish architects now work with computers and CAAD graphics, although automated architecture has not yet become firmly established. The aim of the CAD studio is also to establish an institute which will allow university staff to develop their own programs and to pursue scientific research in this field. On the basis of rising requests from researchers and students, rapid and healthy developments should be made to keep up with new technologies. As the improvement of the specialized involvement with CAD is the future target, MSU is attempting to broaden its horizon by including design methodologies of the last decades.

In the work described here a range of architectural schemes were presented using particular representational techniques and media. An experiment was then undertaken on two different groups; architects and lay people. They were presented with a number of schemes displayed using the various techniques and media. The responses are summarised and some comments are made on the effect of computers on perceiving architecture and on communicating architectural ideas arising from an analysis of the responses.

title Computing and Problem Based Learning at Delft University of Technology Faculty of Architecture
source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 289-294
doi https://doi.org/10.52842/conf.ecaade.1992.289
summary Delft University of Technology, founded in 1842, is the oldest and largest technical university in the Netherlands. It provides education for more than 13,000 students in fifteen main subject areas. The Faculty of Architecture, Housing, Urban Design and Planning is one of the largest faculties of the DUT with some 2000 students and over 500 staff members. The course of study takes four academic years: a first year (Propaedeuse) and a further three years (Doctoraal) leading to the "ingenieur" qualification. The basic course material is delivered in the first two years and is taken by all students. The third and fourth years consist of a smaller number of compulsory subjects in each of the department's specialist areas together with a wide range of option choices. The five main subject areas the students may choose from for their specialisation are Architecture, Building and Project Management, Building Technology, Urban Design and Planning, and Housing.

The curriculum of the Faculty has been radically revised over the last two years and is now based on the concept of "Problem-Based Learning". The subject matter taught is divided thematically into specific issues that are taught in six week blocks. The vehicles for these blocks are specially selected and adapted case studies prepared by teams of staff members. These provide a focus for integrating specialist subjects around a studio based design theme. In the case of second year this studio is largely computer-based: many drawings are produced by computer and several specially written computer applications are used in association with the specialist inputs.

This paper describes the "block structure" used in second year, giving examples of the special computer programs used, but also raises a number of broader educational issues. Introduction of the block system arose as a method of curriculum integration in response to difficulties emerging from the independent functioning of strong discipline areas in the traditional work groups. The need for a greater level of selfdirected learning was recognised as opposed to the "passive information model" of student learning in which the students are seen as empty vessels to be filled with knowledge - which they are then usually unable to apply in design related contexts in the studio. Furthermore, the value of electives had been questioned: whilst enabling some diversity of choice, they may also be seen as diverting attention and resources from the real problems of teaching architecture.

summary Teaching the use of computers in architecture poses the same kind of problems as teaching mathematics. To both there are two possible approaches. The first presents the discipline as a tool of which the merely instrumental aspect is emphasized. Teaching is limited to show the results obtainable by existing programs and how to get them. The second approach, on the contrary emphasizes the autonomous nature of the discipline, mathematics as much as computing, on the basis of the convincement that the maximum of instrumental usefulness can be obtained through the knowledge at the highest degree of generality and, then, of abstraction. The first approach changes little in the mind of the student. He simply learns that is possible, and then worthy doing, a certain amount of operations, mainly checks of performances (and not only the control of the aspect, now easy with one of the many existing CAD) or searches of technical informations in some database. The second approach gives the student the consciousness of the manageability of abstract structures of relationships. He acquires then the idea of creating by himself particular structures of relationships and managing them. This can modify the very idea of the design procedure giving the student the consciousness that he can intervene directly in every segment of the design procedure, reshaping it to some extent in a way better suited to the particular problem he is dealing with. Of course this second approach implies learning not only a language but also the capability of coming to terms with languages. And again it is a cultural acquisition that can be very useful when referred to the languages of architecture. Furthermore the capability of simulating on the computer also a small segment of the design process gives the student a better understanding both of the particular problem he is dealing with and of the very nature of design. As for the first effect, it happens whenever a translation is done from a language to another one. One is obliged to get to the core of the matter in order to overcome the difficulties rising from the different bias of the two languages. The second effect comes from the necessity of placing the studied segment in the general flow of the design process. The organisation in a linear sequence of action to be accomplished recursively in an order always varying in any design occasion is an extremely useful exercise to understand the signification and the techniques of formalisation of design problems.

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 On the Limitations of Shape Grammars: Comments on Aaron Fleisher’s Article “Grammatical Architecture?”

doi https://doi.org/10.52842/conf.acadia.2003.279
summary Shape grammars were introduced by Gips and Stiny in 1972. Since then, there have been many articles and books written by them and their associates. In 1992, Aaron Fleisher, a professor at the School of Planning, MIT, wrote a critique of their work in an article titled “Grammatical Architecture?” published in the journal Environment and Planning B. According to him, Gips, Stiny and later Mitchell, propose a hypothesis that states that shape grammars are presumed to represent knowledge of architectural form, that grammars are “formable,” and that there is a visual correspondence to verbal grammar. The strong version of “the hypothesis requires that an architectural form be equivalent to a grammar.” Fleisher considers these hypotheses unsustainable, and argues his case by analyzing the differences between language, and architecture, and by dealing with the concepts of lexicons, syntax and semantics. He concludes by stating that architectural design is negotiated in two modalities: the verbal and the visual, and that equivalences are not at issue; they do not exist. If there is such thing as a language for design, it would provide the means to maintain a discussion of the consequences in one mode, of the state and conditions of the other. Fleisher’s observations serve as the basis of this paper, a tribute to him, and also an opportunity to present an outline to an alternate approach or hypothesis to shape grammars, which is “nonlinguistic” but “generative,” in the sense that it uses production rules. A basic aspect of this hypothesis is that the only similarity between syntactic rules in language and some rules in architecture is that they are recursive.

title Issues and Experiences Designing and Implementing Two Group Drawing Tools
source Readings in Groupware, 609-620
summary Groupware designers are now developing multi-user equivalents of popular paint and draw applications. Their job is not an easy one. First, human factors issues peculiar to group interaction appear that, if ignored, seriously limit the usability of the group tool. Second, implementation is fraught with considerable hurdles. This paper describes the issues and experiences we have met and handled in the design of two systems supporting remote real time group interaction: GroupSketch, a multi-user sketchpad; and GroupDraw, an object-based multi-user draw package. On the human factors side, we summarize empirically-derived design principles that we believe are critical to building useful and usable collaborative drawing tools. On the implementation side, we describe our experiences with replicated versus centralized architectures, schemes for participant registration, multiple cursors, network requirements, and the structure of the drawing primitives.

This 3D user interface provides a new structure for solving the problems of difficult interface operations and complicated commands due to the application of CAD 2D interface for controlling 3D environment. The 3D user interface integrates the controlling actions of “seeing – moving –seeing” while designers are operating CAD (Schön and Wiggins, 1992). Simple gestures are used to control the operations instead. The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis. The study aims to discuss the provision of more intuitively interactive control through CAD so as to fulfil the needs of designers. In our practices and experiments, a pair of LED gloves equipped with two CCD cameras for capturing is used to sense the motions of hands and positions in 3D. In addition, circuit design is applied to convert the motions of hands including selecting, browsing, zoom in / zoom out and rotating to LED switches in different colours so as to identify images.

title A Graphical Feedback Model for Computerized Energy Analysis during the Conceptual Design Stage
source Texas A&M University
summary During the last two decades, considerable effort has been placed on the development of building design analysis tools. Architects and designers have begun to take advantage of computers to generate and examine design alternatives. However, because it has been difficult to adapt computer technologies to the visual orientation of the building designer, the majority of computer applications have been limited to numerical analysis and office automation tasks. Only recently, because of advances in hardware and software techniques, computers have entered into a new phase in the development of architectural design. haveters are now able to interactively display graphics solutions to architectural related problems, which is fundamental to the design process. The majority of research programs in energy efficient design have sharpened people's understanding of energy principles and their application of those principles. Energy conservation concepts, however, have not been widely used. A major problem in the implementation of these principles is that energy principles their applications are abstract, hard to visualize and separated from the architectural design process. Furthermore, one aspect of energy analysis may contain thousands of pieces of numerical information which often leads to confusion on the part of designers. If these difficulties can be overcome, it would bring a great benefit to the advancement of energy conservation concepts. This research explores the concept of an integrated computer graphics program to support energy efficient design. It focuses on (1) the integration of energy efficiently and architectural design, and (2) the visualization of building energy use through graphical interfaces during the conceptual design stage. It involves (1) the discussion of frameworks of computer-aided architectural design and computer-aided energy efficient building design, and (2) the development of an integrated computer prototype program with a graphical interface that helps the designer create building layouts, analyze building energy interactively and receive visual feedbacks dynamically. The goal is to apply computer graphics as an aid to visualize the effects of energy related decisions and therefore permit the designer to visualize and understand energy conservation concepts in the conceptual phase of architectural design.

title CONTEXTUALIZATION AND EMBODIMENT IN CYBERSPACE

summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

title A functional approach to realizing decision support systems in technical regulation management for design and construction
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 Technical building standards defining the quality of buildings, building products, building materials and building processes aim to provide acceptable levels of safety, health, usefulness and energy consumption. However, the logical consistency between these goals and the set of regulations produced to achieve them is often hard to identify. Not only the large quantities of highly complex and frequently changing building regulations to be met, but also the variety of user demands and the steadily increasing technical information on (new) materials, products and buildings have produced a very complex set of knowledge and data that should be taken into account when handling technical building regulations. Integrating knowledge technology and database technology is an important step towards managing the complexity of technical regulations. Generally, two strategies can be followed to integrate knowledge and database technology. The main emphasis of the first strategy is on transferring data structures and processing techniques from one field of research to another. The second approach is concerned exclusively with the semantic structure of what is contained in the data-based or knowledge-based system. The aim of this paper is to show that the second or knowledge-level approach, in particular the theory of functional classifications, is more fundamental and more fruitful. It permits a goal-directed rationalized strategy towards analysis, use and application of regulations. Therefore, it enables the reconstruction of (deep) models of regulations, objects and of users accounting for the flexibility and dynamics that are responsible for the complexity of technical regulations. Finally, at the systems level, the theory supports an effective development of a new class of rational Decision Support Systems (DSS), which should reduce the complexity of technical regulations and restore the logical consistency between the goals of technical regulations and the technical regulations themselves.

summary The use of computer tools in architectural practice has been steadily increasing in recent years. Many architectural offices are already using computer tools, mostly for production tasks. Hardly any design is being done with the computer. With the new computer tools, architects are confronted with the challenge to use computers to express their design ideas right from conception.

This paper describes a project made for a competition which recently took place in Spain. Sketches and computer models were the only tools used in designing this project. A variety of computer tools were used in different stages of this project: two dimensional drawing tools were used in the early stages, then a three-dimensional modeling program for the development of the design and for the production of final drawings, and a rendering program for final presentation images.

title Multiple Operative and Interactive Modes in Knowledge-Based Design Systems
source New York: John Wiley & Sons, 1992. pp. 125-143 : ill. includes bibliography
summary A conceptual basis for the development of an expert system which is capable of integrating various modes of generation and evaluation in design is presented. This approach is based upon two sets of reasoning processes in the design system. The first enables a mapping between design requirements and solution descriptions in a generative mode of design; and the second enables a mapping between solution descriptions and performance evaluation in an evaluative and predictive mode. This concept supports a formal framework necessary for a knowledge-based design system to operate in a design partnership relation with the designer. Another fundamental concept in expert systems for design, dual direction interpretation between graphic and textual modes, is presented and elaborated. This encoding of knowledge behind the geometrical representation can be achieved in knowledge- based design systems by the development of a 'semantic interpreter' which supports a dual direction mapping process employing a geometrical knowledge, typological knowledge and evaluative knowledge. An implemented expert system for design, PREDIKT, demonstrates these concepts in the domain of kitchen design. It provides the user with a choice of alternative modes of interaction, such as: a 'design critic' for the evaluation of a design, a 'design generator' for the generation of a design, or a 'design critic-generator' for the completion of partial solutions

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 In this paper we present a hierarchical decision support system for the allocation of organisations to available buildings, and for the allocation of employees of an organisation to the work units of a building. For both allocation problems a mathematical model and optimisation algorithm is developed, taking into account the relevant criteria, such as the extent to which the allocated floorspace is in accordance with the standards, and the extent to which departments are housed in connecting zones of a building. The decision support system is illustrated by two practical applications.

title THE MEASURABLE AND THE UNMEASURABLE OR - FROM FORM TO DESIGN TO EXISTANCE
source Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part B, pp. 55-62
summary This article discusses the architectural design process from two sides of the spectrum: the formal exercises of experts and the participatory process involving users. The "place" of the full-scale-modelling laboratory at the Federal Institute of Technology in Lausanne is then assessed with respect to this spectrum. It may seem that activities in a full-scale laboratory are closer to the participation process than to formal exercises. However, activities of the full-scale laboratory in Lausanne may best be situated around the middle of the design process. It is clearly within the realm of the measurable (since each construction can easily be measured.) Yet, it does not quite correspond to the real building; it remains an abstraction, a model. And in this quality of abstraction lies the potential to give form to the unmeasurable. It is a tool which allows a transformation of the unmeasurable aspects of an idea into the unmeasurable of existence.
