title	The Computability of Architectural Knowledge

summary	In an important contribution to the theoretical foundation of design computing, Mitchell noted "an increasingly urgent need to establish a demonstrably sound, comprehensive, rigorously formalized theoretical foundation upon which to base practical software development efforts" (Mitchell, 1986). In this paper we propose such a theoretical framework. A basic assumption of this work is that the advancement of design computing is dependent upon the emergence of a rigorous formulation of knowledge in design. We present a model of knowledge in architectural design which suggests a promising conceptual basis for dealing with knowledge in computer-aided design systems. We require models which can represent the formal knowledge and manipulative operations of the designer in all of their complexity-that is formal models rather than just geometric models. Shape Grammars (Stiny,1980) represent an example of such models, and constitute a relatively high level of design knowledge as compared to, for example, use of symmetry operations to generate simple formal configurations. Building upon an understanding of the classes of design knowledge as the conceptual basis for formal modeling systems may contribute a new realization of the potential of the medium for design. This will require a comprehensive approach to the definition of architectural and design knowledge. We consider here the implications of a well-defined body of architectural and design knowledge for design education and the potential mutual interaction-in a knowledge-rich environment-of design learning and CAAD learning. The computational factors connected with the representation of design knowledge and its integration in design systems are among the key problems of CAAD. Mitchell's model of knowledge in design incorporates formal knowledge in a comprehensive, multi-level, hierarchical structure in which types of knowledge are correlated with computational concepts. In the main focus of this paper we present a structured, multi-level model of design knowledge which we discuss with respect to current architectural theoretical considerations. Finally, we analyze the computational and educational relevance of such models.

summary	Conventional computer systems currently used by architecture and landscape architecture are not addressing complex decision making, system interface, dynamic manipulation and real time visualization of data. This paper identifies a strategy by which Canadian Schools could form a supportive network, incorporate and expand their research development. Within this larger framework schools would have better tools, a larger research base and access to funding as a group. The following discussion is an idea of what we at the Canadian Schools need to do differently over the next five years in our research and teaching in order to make a unique contribution to our fields.

title	Computer Modeling: A First Course in Design Computing
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 61-76
summary	Computation in design has long been a focus in our department. In recent years our faculty has paid particular attention to the use of computation in professional architectural education. The result is a shared vision of computers in the curriculum [Woodbury 1985] and a set of courses, some with considerable historyland others just now being initiated. We (Dave and Woodbury) have jointly developed and at various times over the last seven years have taught Computer Modeling, the most introductory of these courses. This is a required course for all the incoming freshmen students in the department. In this paper we describe Computer Modeling: its context, the issues and topics it addresses, the tasks it requires of students, and the questions and opportunities that it raises. Computer Modeling is a course about concepts, about ways of explicitly understanding design and its relation to computation. Procedural skills and algorithmic problem solving techniques are given only secondary emphasis. In essential terms, the course is about models, of design processes, of designed objects, of computation and of computational design. Its lessons are intended to communicate a structure of such models to students and through this structure to demonstrate a relationship between computation and design. It is hoped that this structure can be used as a framework, around which students can continue to develop an understanding of computers in design.

title	CAD Tools for Systems Theory and Bottom Up Design
doi	https://doi.org/10.52842/conf.acadia.1989.209
source	New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 209-226
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	The Economics of Building : A Practical Guide for the Design Professional
source	xvii, 209 p. : ill. New York: John Wiley & Sons, 1990. includes bibliography
summary	This book is both an introduction to economic principles and theories as they relate to building design decisions, and a practical reference guide on how to use economic principles when making decisions. It unites a variety of specialized topics relating to building economics, such as cost estimating, life-cycle costing, cost indexes, capital budgeting, decision analysis, and real estate feasibility analysis, developing them within the framework of an integrated approach to making building design and management decisions. This integrated approach is developed by adapting basic approaches of decision theory to economic evaluation. This book attempts to achieve a sensible balance between the need to simplify relatively complex economic and decision theory principles and practices without sacrificing the intellectual content of the material

summary	There will likely be an intensive colonization movement into space within the foreseeable future. Presupposing eventual adaptation to the microgravitational environment, the structural, habitable, and meaningful environment Space Architecture will be fundamentally redefined. The primary shift in spatial conception will be from a two-dimensional decentralized horizontal schema with singular up-down vertical axis, to a three-dimensional centralized polyaxial schema with in-out the primary existential axis. Mega- structures are proposed, which provide ample habitable space in Space. Their structure is provided by means centralized tensile lattices stressed by pneumatic enclosures. These are envisaged to be large-scale, of about 13 kilometers in diameter each. with Primary Tensile Lattice ties of 1 km. length. The geometry of the tensile lattice is given by the author's centralized polyaxial zonahedral expansions. Secondary tensile assemblages are then stressed by means of the primary tensile lattice, with tertiary and subordinate assemblages as desired. This permits a 'soft' non-rigid architecture to be developed. Principles of traditional architecture are relevant to space habitation studies, and indicate Space Habitation theory should seek to integrate metaphysical, psychic, and physical human needs appropriate to dwelling in microgravity. Ideally the Space Habitation should integrate structure form and meaning

summary	A graphic data base of our campus is being developed to record physical inventory and to provide a three- dimensional development tool for the University. The campus has many changes in elevation. Computer terrain modeling is planned to provide traditional contour information as well as to furnish a base for perspective views of the campus. Selecting an appropriate geometry to record the landform, and determining criteria for coloration of the ground surface is critical to the success of the project. Methods of modeling a three-dimensional surface are discussed; color principles which articulate landform are explored. A methodology is illustrated which achieves a flexible model of the campus landform.

title	Conceptual Content of Digital Design
doi	https://doi.org/10.52842/conf.ecaade.2005.115
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 115-121
summary	Concepts related to digital architecture have begun to occupy a central role in current architectural discourse. Design concepts that have been the conceptual content of this discourse are now becoming integrated into the general architectural discourse. The research reports on this process of the emergence, migration, and crystallization of a new conceptual structure over the past decade under the influence of digital design and its emerging conceptual structure. The research presented in this paper examines the emergence of new ideas in architectural thinking that are related to digital architecture since 1990 until today. In order to demonstrate this shift, we have selected a representative architectural building type that is strongly and directly influenced by the conceptual content of the cultural discourse in architecture. A museum type was selected to represent features of the expression that reflects the changes and evolution of conceptual structures that underlie digital design. The research methodology is based on a method known as “content analysis”. Content analysis in our research was de- fined as including textual material in books, book chapters, essays, articles, and historical documents. A new approach for Design Content Analysis was accomplished employing the ICF analytical framework. In order to conduct a content analysis the text was coded and was broken down into categories on a variety of theoretical design themes. Our findings demonstrate that certain expressions related to digital technology have moved up from a low level descriptive function to a significant conceptual role in formulating the design content of architectural design. In our paper we describe the research, methodology findings and contribution to the definition of the conceptual content of contemporary architectural discourse on digital architecture.

title	Prior Knowledge in Design : A Dynamic Knowledge-based Model of Design and Creativity
source	Design Studies. January 1990. vol. 11: pp. 17-28 : ill. includes bibliography
summary	The incorporation of precedents into a present design situation by adaptation, restructuring and reformulation depends upon processes of typification and generalization. The function of prototypes as a characteristic form of generalized and structured knowledge in design is described. A precedent-based design model employing memory-based reasoning is proposed. It is argued that typological concepts can serve as a matching level between situation types and solution types. In such an approach both the organization of structured knowledge and the mechanisms of matching to prior knowledge such as cross-indexing and analogy appear to be of seminal importance. A memory-based reasoning process in routine, innovative and creative design is postulated. This is based on concepts of dynamic and episodic memory. Relevant work in the fields of memory organization, machine learning and analogical reasoning is considered with respect to its significance to the field of knowledge-based design

title	The Role of Knowledge-Based Systems in Design and Design Education
source	Int. J. Appl. Enging, Ed England: Pergamon Press, 1990. vol. 6: pp. 255-264 : ill. includes bibliography.
summary	This paper investigates the role of Artificial Intelligence and Knowledge Based Design in the emergence of a 'general design science' common to all engineering design. The advantages of the design shell's approach is demonstrated relative to the utilization of expert systems for design. The design shell is proposed as a medium to accommodate the characteristics of design knowledge. The significance of this concept is discussed with respect to formalization of knowledge, implementation, application and operation in knowledge based systems. GRPS - a generative prototype refinement design shell is defined and elaborated. A system applying this concept in a significant structure of generic knowledge in architectural design is demonstrated. It utilizes a method for representing structured knowledge by exploiting the characteristics of both rules and frames, and integrates them in a prototype based design system. Finally, the significance of such an approach in research and design teaching is discussed

summary	The concept of a knowledge based design shell is proposed as a basis for teaching design. The significance of the concept of design shell is discussed with respect to formalization, implementation, application and operation. GPRS-a generative prototype refinement design shell-is proposed, defined and elaborated. A plan type is introduced as one significant kind of structure of knowledge in architectural design is introduced. A method for representing syntactic and the semantic content to be used in design refinement is proposed. The method exploits the characteristics of both rules and frames, and integrates them in a prototype-based design system. This is demonstrated in a system called PRODS. Finally, the significance of such an approach in teaching is discussed.

title	Computer-Aided Architectural Design Strategies: One Size Does Not Fit All
doi	https://doi.org/10.52842/conf.acadia.1991.015
source	Reality and Virtual Reality [ACADIA Conference Proceedings / ISBN 1-880250-00-4] Los Angeles (California - USA) October 1991, pp. 15-31
summary	The practice of architecture is in the midst of significant change and an increasingly uncertain future. Socio-economic factors external to the profession are forcing firms to develop new strategies for delivering design services. Overlaying these external changes is the uncertainty resulting from the inevitable introduction of information technology, which is only beginning to have an impact on the profession. Some advocates see the emergence of a new form of design firm -the computerized design firm - as an intelligent organization structured around electronic work groups with powerful computation and communications tools (Catalano 1990). On the other hand, many practitioners still see CADD as an expensive technology whose primary result leads to an increase in overhead costs. But some practitioners and researchers (Coyne, 1991) recognize both the potential and, problems that computer-aided design presents to the profession. This research presents a framework for understanding how changing information technology might be appropriately integrated into the design firm. It argues that design is an increasingly diverse enterprise, and that this diversity must be understood in order to effectively integrate information technology. The study is divided into three sections. The first section develops an overview of major social, economic, and structural changes within the profession. The second section discusses two alternative approaches that have been utilized to integrate information technology into firms. The third part presents a framework for understanding how information technology may have an impact on strategies for structuring and organizing architectural firms.

source	From Research to Practice [ACADIA Conference Proceedings] Big Sky (Montana - USA) 4-6 October 1990, pp. 45-59
summary	After a discussion of the problematic relationship between architectural history, computer aided design and the design studio, a course is described which provides an overview of the history of urban form through readings and three-dimensional modeling by computer. One objective of the course was to model a hypothetical, archaic Greek city on a hypothetical but realistic site and to transform the model of that city through time to the 20th century. An overview is given of the computer modeling techniques, of the successes and failures of the first offering of the course and of suggestions for improving future offerings of the course.

title	Variations in Solids : A Declarative Treatment
source	Computers and Graphics. April, 1990. Vol. 14: 40 p. : ill. includes bibliography
summary	Underlying the notions of variational geometry, design prototypes, features, and representation of assemblies seems to be a common concept of variations. This paper develops the core of a monotonically declarative system for variations on solids. It introduces a set of language constructs that are the basis for ASCEND, an object oriented equation solving language. It presents equations for representing certain spatial relationships between primitive geometric elements. Using plex grammar notation it develops a set of Euler operators that are monotonic in the strict sense required by the ASCEND language. These operators are collectively shown to generate representations for all plane models of 2-manifold objects and to generate only such representations. Finally it presents the core of a system for variations using the ASCEND language to implement both equation models and the new Euler operators

title	Precedents: Memory Structure in Design Case Libraries
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 273-287
summary	The paper presents an approach to a memory structure of design ideas in a library of design precedents. A model of case memory for design is developed. The model is composed of distinct chunks of knowledge called design stories. A formalism for the design story is proposed which represents the linkage between design issue, concept and form in stories. Stories are structured in memory according to a semantic network. The lexicon of the semantic network acts as a memory index. The memory structure and indexing system are demonstrated to enhance search and to support crosscontextual browsing and exploration in the precedent library. The approach is demonstrated in a pilot design aid system in the task domain of early conceptual design in architecture.

source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 313-328
summary	Within a transformational paradigm of form generation, refinement and adaptation are presented as two distinct concepts which can provide formalisms for encoding design knowledge. Refinement and adaptation are treated as syntactical models of form generation. Computational formal analysis is proposed as a method for the study and modelling of refinement and adaptation in design. Employing the analytical method we demonstrate that formal transformations are dependent upon their membership in classes of architectural designs. Computational issues inform generation through refinement and adaptation are identified.

summary	With the development of storage media such as the CD ROM, the availability and usage of very large data bases of information has dramatically opened new vistas for the creation of electronic libraries. From dictionaries and encyclopedias to historical treatises, the electronic packaging of large and cumbersome information sources has begun to demonstrate its utility and efficiency. Today the bridge to an unknown territory of electronic knowledge resources lies here at the boundary between the passive (though electronically accelerated) access to information through electronic books and the user interactive access to knowledge. This paper is about that boundary.

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