title A Case Study in Knowledge-Based System Development : Envelope Design for Reduction of Traffic Noise Transmission
source February, 1990. 19 p. : some ill. and table. includes a bibliography
summary Researchers have demonstrated the value of replication of research and explicit testing of concepts in artificial intelligence (Ritchie and Hanna 1989). In this study, a rule- based system was implemented as an exercise in the application of the theory and practice of knowledge-based systems development to architectural design analysis. The test domain was the selection of wall and window assemblies to provide adequate noise reduction given a set of traffic and building site conditions. This domain was chosen for two reasons: (1) considerable detailed heuristic information was available; and (2) it avoided large solutions spaces, 'errorful' and time-dependent data, and unreliable knowledge. Development of the system in conjunction with an extensive literature review revealed that publications on construction and performance of rule-based systems provided insufficient detail on key aspects of system architecture. Topics suffering from neglect or insufficiently rigorous treatment included algorithms used in automated inference, methods for selection of inference procedures, the integration of numerical and symbolic processing, the formulation of explanation mechanisms to deal with integrated numerical and symbolic processing, testing methods, and software standardization. Improving the quality and scope of knowledge in these areas is essential if expert systems are to be applied effectively in architectural design

title Application of Expert Systems to Building Design Analysis and Evaluation
source Building and Environment. 1990. vol.25: pp. 221-233
summary This paper demonstrates the applicability of expert systems to design analysis and evaluation. Design is a field in which a large part of the processes involved is knowledge-based rather than computation-based. Much of this knowledge is experiential and as such lends itself to be encapsulated in an expert system. An analogy is made between analysis and interpretation and between evaluation and comparison of interpretations. Three examples of expert systems carrying out design analysis and evaluation in different domains are described. It is argued that a graphical interface and a model of the elements within the domain are essential parts of any design system

title Computational Design Instruction: Toward a Pedagogy

summary The computer offers enormous potential both in and out of the classroom that is realized only in limited ways through the applications available to us today. In the early days of the computer it was generally argued that it would replace the architect. When this idea became obsolete, the prevailing opinion of proponents and opponents alike shifted to the notion of the computer as merely adding to present design capabilities. This idea is so ingrained in our thinking that we still speak of "aiding" design with computers. It is clear to those who grasp the real potential of this still new technology - as in the case of many other major technological innovations - that it continues to change the way we design, rather than to merely augment or replace human designers. In the classroom the computer has the potential to radically change three fundamental ingredients: student, instruction, and instructor. It is obvious that changes of this kind spell out a commensurate change in design pedagogy. If the computer is going to be more than a passive instrument in the design studio, then design pedagogy will have to be changed, fundamentally. While the practice of computing in the studio continues to be a significant I aspect of architectural education, articulation of viable pedagogy for use in the design studio is truly rare. In this paper the question of pedagogy in the CAD studio will be considered first. Then one particular design studio taught during Fall 1988 at Carnegie Mellon University will be presented. Finally, we shall return to issues of change in the student, instruction, and instructor, as highlighted by this particular experience.

title A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.

summary This paper examines the use of computation in participatory housing design, and discusses its history, ideals and limitations. Drawing from archival material and personal interviews, the authors compare four case studies: The Calculation Center of the University of Madrid (1969-1972), the Stichting Architecten Research (1975-1990), WikiHouse (2011-present), and Automated Architecture (2019-present). This genealogy reveals an evolution from the use of mainframe computers to desktop computers then web tools and robotic arms, and from modular prefabricated systems to mass-customized digital fabrication. It argues that despite technological development, a combinatorial approach to choice and participation has persisted, where the main author designs an algorithmic object and secondary authors (or end-users) adapt and adjust some limited variable aspects at will. The paper demonstrates the possibilities and limitations of such an approach. It argues that while this methodology offers disruptive changes into the economic underpinnings of industrial production, it also limits user participation to the act of selecting from a pre-defined menu of alternatives.

summary In this paper we present a model for handling design information in the early design phases. This model can be used for representing both vague and exact defined information. The first part describes the difficulties involved in using CAD in the architectural design process and the characteristics of that process. Then we give a description of the design information and its representation during the design process. Next an overview of the architectural design process describes how design information is added and manipulated during the design process in order to achieve an effective result. Finally, we include a brief description of a simple prototype program to illustrate how this theory acts in practice.

summary The use of CAD is investigated in the teaching of systems theory to a fourth year group of design students. A comparison is made between the CAD group using MacArchitrion and a non-CAD group using traditional design methods. The paper includes a discussion of the meaning of systems design theories, relates the CAD and non-CAD student design methods and illustrates the results. It also includes recommendations for improvements so the computer can become more effective in this type of design teaching. Finally, it concludes with recommendations from the students at the end of the semester project. The basic premise for the CAD design group is that computers should encourage students to understand and use systems design theory.

title Interactive design of parameterized 3D models by direct manipulation
source Delft University of Technology
summary The practical applicability of a computer-aided design system is strongly influenced by both the user interface and the internal model representation. A well designed user interface facilitates the communication with the system by offering an intuitive environment for for specification and representation of model information. An internal model representation, capable of storing geometric, topological and hierarchical dependencies between components in a model, increases the efficiency of the system by facilitating modification and elaboration of the model during the different stages of the design process. The subject of this thesis is the integration of a high level parameterized model representation with direct manipulation interface techniques for the design of three-dimensional objects. A direct manipulation interface enables the user to specify a model by interaction on a graphical representation, as an alternative for an abstract and error-prone apha-numerical dialogue style. A high level model representation is obtained by using a procedural modeling language with general purpose control structures, including arithmetic and logical expressions, repetition, conditionals, functions and procedures, and dedicated data types such as coordinate systems, geometric primitives and geometric constraints. The language interpreter is interconnected with a graphical interface, an incremental constraint solver and a geometrical modeler, using visual programming techniques. The developed techniques are implemented in a modeling system called GeoNode. The system incorporates paradigms of object-oriented design, with respect to both the user interface and to the system implementation. The applicability of the presented techniques is illustrated by examples in application domains such as solid modeling, kinematic analysis, feature modeling and top-down design.

title Generative and Evolutionary Techniques for Building Envelope Design
source International Conference on Generative Art
summary The authors have been involved in the use of generative techniques for building envelope design since 1968 and the use of genetic algorithms since 1990. Recent work has focused on incorporating optimisation functions into form generating processes in order for new forms responding to varied design environments to be created and determined. This paper will summarise the authors’ previous work in this field and explain the theory behind this approach, and illustrate recent developments. While the initial implementation of a new building envelope design system is reported in more details in a related paper at this conference, this paper outlines its main features and points out the direction at which it is to be fully developed and further improved.

summary Analogous to music sampling, in which sounds from the environment are recorded, distorted and used in unique ways to create music, "image sampling" is the visual equivalent of a sound bite used to create new visual forms, textures, patterns and types of architecture. Through the use of image sam ling, a designer can accurately record and digitize images from the existing visual world: rom the physical (built or natural) context of the site, from history (a specific building " or a significant architectural monument) or from previous work produced by the designer. The digital scanning process makes design information equal and uniform, as it converts all images to dot patterns of varying color. As a result the image can be transformed through numeric operations (even when the algorithms are transparent to the end user). The recorded images can therefore be fragmented, combined, distorted, duplicated, tweened, or subjected to random automated operations. Because computer images are digital, they facilitate modification and transformation, unlike their analog counterparts. Merging video and image processing capabilities with three-dimensional modeling permits the designer to collage visual information into new and readily editable architectural proposals. Combining image samples into new architectural concepts expands the scope of potentials available to the architect and also raises fundamental questions about issues of originality, creativity, authenticity, and the nature of the design process itself. What is original work, created by the designer, and what is merely re-used? The discussion of new digital imaging eventually leads to questions about design theory and ethics, in addition to those associated with computer technology and architectural form. As one works in any new medium, including the digital environment, many questions are raised about its impacts on design. Much of what is presented in this paper are early speculations on the implications of the digital technology and its influence on architecture.

summary For the tenth time in as many years, the Association for Computer-Aided Design in Architecture (ACADIA) has invited architectural educators and professionals to discuss their activities and interests related to computer-aided architectural design. This annual meeting has grown from a small group representing a handful of schools to a conference with international participation. For the fifth time, the papers presented at this annual conference have been collected and published in a bound volume as the conference proceedings. In organizing these meetings, ACADIA must be viewed has having firmly established itself as a valuable forum for those who are interested and active in this area. Moreover, the proceedings of these conferences have become an important record for documenting the progress of ideas and activities in this field. This organization and its annual conferences have been a critical influence on my own professional development. The first conference I attended, ACADIA '86, confirmed a nagging suspicion that courses in computer-aided design (CAD) offered at the university level should be more than vendor training. Papers and conversations at subsequent conferences have reinforced this conviction and strengthened my commitment to CAD education which does more than convey electronic drawing technology. At the same time, I have been frustrated at the apparent lack of communication between those involved in these activities in architectural education and the average professional practice. With some notable exceptions, architects are only beginning to make basic computer-aided drafting pay for itself. In many small offices, "The CAD Computer" remains more decoration and status symbol than useful tool. While it can be argued that the economics of computer-aided drafting have only recently become attractive, it must be admitted that many members of ACADIA are actively involved in the development and use of computer applications which are significantly more challenging. In the short run, most of these activities will go largely unnoticed by the community of practicing architects. This situation raises a number of questions on the value of the work produced by members of ACADIA. One can (and many do) challenge the worth of "design" research produced by academia to those in professional practice. However, it is a fundamental mistake to insist that such work be of immediate and direct relevance to the profession. In fact, some presentations at the ACADIA conferences have focused solely on the pedagogical environment (which may be of some intellectual interest) but do not even attempt to address professional design issues. Other work may serve as the basis for further activities which may result in useful applications at some future point in time. Such work is strategic in nature and should not be expected to bear fruit for many years. These are the *natural" products of a university environment and, indeed, may be what the university does best. Still, design professionals remain indifferent (if not somewhat hostile) to these endeavors. The central dilemma resides in the ongoing debate about the fundamental goals of professional education. A number of design professionals believe that architectural education should follow more of a “trade school” model where a professional degree program becomes solely a process of acquiring (and practicing) a set of skills which are directly and immediately useful upon graduation. Today these people stiR closely examine the drafting skill of any recent graduate, but they are also likely to demanding expertise on AutoCAD. It is my view that this position tends to deprecate the image of architects and depreciate the economic status of the profession. On the other hand, there is a similar minority in architectural academia who teach because they are unable or unwilling to deal with the very real complexities and challenges of professional practice. These instructors tend to focus on obscure theory and academic credentials while discounting the importance of professional development. For most who participate in this discussion, it is becoming increasingly clear that professional competency must be founded on an effective marriage of intellectual theory and practical expertise. This must lead to the conclusion that CAD research must recognize and give serious consideration to the professional agenda in a substantive manner without abandoning those activities which deal with strategic and pedagogical issues.

summary McIntosh, in ACADIA Newsletter Vol. 9 No. 3 pp 20-23, June 1990. This book introduces the concept of modeling objects in the computer's memory so it can be used to aide the process of their design. Modeling is defined as an hierarchical abstraction of data and operators to manipulate it, subject to semantic integrity constraints that guarantee the realizability of the designed artifact in the real world. Starting with general concepts of modeling, the book moves on to discuss the modeling of shapes (form) in two and in three dimensions. The discussion covers both topology and geometry. Next the book introduces the concept of shape transformations (translation, scaling, rotation, etc.), both in absolute and in relative terms. The book then introduces the concept of assembly modeling, and adds non-graphical attributes to the representation. It concludes with a discussion on user interface and parametrization. The book includes many examples written in Pascal that complement the theory, and can be used as a basis for building a geometric modeling engine. It also includes exercises, so it can be used as a text book for a two-semester advance course in geometric modeling

title Development of a computerized handbook of architectural plans
source Delft University of Technology
summary The dissertation investigates an approach to the development of visual / spatial computer representations for architectural purposes through the development of the computerized handbook of architectural plans (chap), a knowledge-based computer system capable of recognizing the metric properties of architectural plans. This investigation can be summarized as an introduction of computer vision to the computerization of architectural representations: chap represents an attempt to automate recognition of the most essential among conventional architectural drawings, floor plans. The system accepts as input digitized images of architectural plans and recognizes their spatial primitives (locations) and their spatial articulation on a variety of abstraction levels. The final output of chap is a description of the plan in terms of the grouping formations detected in its spatial articulation. The overall structure of the description is based on an analysis of its conformity to the formal rules of its “stylistic” context (which in the initial version of chap is classical architecture). Chapter 1 suggests that the poor performance of computerized architectural drawing and design systems is among others evidence of the necessity to computerize visual / spatial architectural representations. A recognition system such as chap offers comprehensive means for the investigation of a methodology for the development and use of such representations. Chapter 2 describes a fundamental task of chap: recognition of the position and shape of locations, the atomic parts of the description of an architectural plan in chap. This operation represents the final and most significant part of the first stage in processing an image input in machine environment. Chapter 3 moves to the next significant problem, recognition of the spatial arrangement of locations in an architectural plan, that is, recognition of grouping relationships that determine the subdivision of a plan into parts. In the absence of systematic and exhaustive typologic studies of classical architecture that would allow us to define a repertory of the location group types possible in classical architectural plans, Chapter 3 follows a bottom-up approach based on grouping relationships derived from elementary architectural knowledge and formalized with assistance from Gestalt theory and its antecedents. The grouping process described in Chapter 3 corresponds both in purpose and in structure to the derivation of a description of an image in computer vision [Marr 1982]. Chapter 4 investigates the well-formedness of the description of a classical architectural plan in an analytical manner: each relevant level (or sublevel) of the classical canon according to Tzonis & Lefaivre [1986] is transformed into a single group of criteria of well-formedness which is investigated independently. The hierarchical structure of the classical canon determines the coordination of these criteria into a sequence of cognitive filters which progressively analyses the correspondence of the descriptions derived as in Chapter 3 to the constraints of the canon. The methodology and techniques presented in the dissertation are primarily considered with respect to chap, a specific recognition system. The resulting specification of chap gives a measure of the use of such a system within the context of a computerized collection of architectural precedents and also presents several extensions to other areas of architecture. Although these extensions are not considered as verifiable claims, Chapter 5 describes some of their implications, including on the role of architectural drawing in computerized design systems, on architectural typologies, and on the nature and structure of generative systems in architecture.

summary Design is the computation of shape information that is needed to guide fabrication or construction of artifacts. But it is not so straightforward as, say, the computation of numerical information required to balance a checkbook. This is partly because algebras of shapes are not as well understood and precisely formalized as algebras of numbers, partly because the rules for carrying out shape computations tend to be fluid and ill defined and partly because the predicates that must be satisfied to achieve successful termination are often complex and difficult to specify. For centuries architects have carried out shape computations by hand, using informal procedures and the simplest of tools. Over the last two decades though, they have made increasing use of more formal procedures executed by computers. It is still too early to be sure of the gains and losses that follow from this development, but there is no doubt that it raises some challenging questions of architectural theory and some perplexing issues for those concerned with the future of architectural education. This book frames those issues and provides a diversity of perspectives on them. Its contents were initially presented at the CAAD Futures 89 Conference-an international gathering of researchers and teachers in the field of computer-aided architectural design which was jointly sponsored by the Harvard Graduate School of Design and the MIT Department of Architecture and held in Cambridge, Massachusetts, in July 1989. There are four major sections: Theoretical Foundations, Knowledge-Based Design Tools, Information Delivery Systems, and Case Studies: Electronic Media in the Design Studio. In a representative collection of current views, over thirty extensively illustrated papers discuss the experiences of universities in the USA, Europe, Japan, Israel, Canada, and Australia, articulate present theoretical and practical concerns, provide criticism of media and methods, and suggest directions for the future. Architectural educators and architects concerned with the effect of computer technology on the design process will find here an indispensable reference and a rich source of ideas. This book was itself prepared in an electronic design studio. Composition and typography, most image collection and placement, and such editing as was practical within this publishing format, were all performed digitally using Macintosh computers at the Harvard Graduate School of Design during a period of a few weeks in 1989.

title The Logic of Architecture: Design, Computation and Cognition
source The MIT Press, Cambridge
summary The Logic of Architecture is the first comprehensive, systematic, and modern treatment of the logical foundations of design thinking. It provides a detailed discussion of languages of architectural form, their specification by means of formal grammars, their interpretation, and their role in structuring design thinking. Supplemented by more than 200 original illustrations, The Logic of Architecture reexamines central issues of design theory in the light of recent advances in artificial intelligence, cognitive science, and the theory of computation. The richness of this approach permits sympathetic and constructive analysis of positions developed by a wide range of theorists and philosophers from Socrates to the present. Mitchell first considers how buildings may be described in words and shows how such descriptions may be formalized by the notation of first order predicate calculus. This leads to the idea of a critical language for speaking about the qualities of buildings. Turning to the question of representation by drawings and scale models, Mitchell then develops the notion of design worlds that provide graphic tokens which can be manipulated according to certain grammatical rules. In particular, he shows how domains of graphic compositions possible in a design world may be specified by formal shape grammars. Design worlds and critical languages are connected by showing how such languages may be interpreted in design worlds. Design processes are then viewed as computations in a design world with the objective of satisfying predicates of form and function stated in a critical language.

summary Computer-aided architectural design is design with color - the monitor of a CAAD system is a display of color, a place where images are produced by color manipulation. The success of these images can be judged by the ability of the colors selected to communicate graphic ideas and to convey graphic information. Color as a visual phenomena intrigued the impressionist painters at the end of the nineteenth century; it was the focus of much attention at the Bauhaus in Weimar Germany. When Johannes Itten was appointed as a Master of Form at the Bauhaus in 1919, he developed "an aesthetic color theory originating in the experience and intuition of a painter". In his definitive work, Itten postulates seven ways to communicate visual information with color. "Each is unique in character and artistic value, in visual, expressive and symbolic effect, and together they constitute the fundamental resource of color design". These seven contrasts provide a lexicon of the methods by which computer images convey graphic information. The colors which form a computer image can be simply manipulated to illustrate these contrasts; today's computers make color manipulation a very simple matter. This paper is composed of short essays about each of these contrasts and how they can guide the selection of appropriate colors to convey visual intent on a picture tube. Considered together the contrasts of Itten provide a fundamental resource for electronic graphic communication.
