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.

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

title	Modeling Objects and Environments
source	xix, 402 p. : ill. New York: Wiley, 1989. includes a short bibliography and index. Part of the Principles of Computer Aided Design series. --- See also review by Patricia G
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	The Thousand-Acre Sketch Problem
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. 427-440
summary	An unusually large sketch problem in urban design was given to an undergraduate studio class to introduce visualization techniques and to explore fundamental urban design principles. This thousand-acre sketch problem was distributed to students on a floppy disk as a three- dimensional computer model. The availability of a large number of Macintosh IIs and access to a pre-release version of the three-dimensional modeling program ModelShop allowed us to conduct this prototype electronic studio. This paper looks at the productivity gains experienced by our students during this project and discusses the increased level of understanding witnessed in student performance. More importantly, this sketch problem is examined as a philosophical parable for several pedagogical issues of design education in the microcomputer age.

title	Computational Design Instruction: Toward a Pedagogy
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. 302-316
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 Hypermedia Model for Supporting Energy Design in Buildings
doi	https://doi.org/10.52842/conf.acadia.1994.039
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49
summary	Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title	Experiments as Modus Operandi
source	Journal of Architectural Education. November, 1990. Vol. 44: pp. 37-48 : 9 p. of ill
summary	Architecture has for too long focused on the presentation of pristine objects and the presentation in drawing form. A critical understanding of the field, however, necessitates a reevaluation of the roles of the process involved in the production of building. Rather than emphasizing surface appearances, an architecture rooted in process aims ultimately at revealing the fundamental and deep structures inherent within the making of architecture. One of the primary tasks of the process is to provoke intuition and ingenuity - and the awareness that both are founded on knowledge - and that knowledge must be applied with imagination. The experiment presented here developed sequentially with a defined structure to the process of design, moving gradually from the abstract into the concrete, thereby attempting and understanding of what Roland Barthes identified as 'concrete abstraction.'

summary	Application of solid modeling in computer-aided design, computer-aided manufacturing, and robotics often involve aggregates or assembling of disconnected pieces. This article presents an alternative CSG-like formalism based on open sets, in which both assemblies and connected pieces are modeled as points sets. Consequently, the same Boolean operations apply uniformly to connected pieces and assemblies

summary	This paper describes concepts which allow the development of integrated systems that combine the two technologies of expert systems and computer-aided drafting systems. It demonstrates how an expert system can be used for evaluating and criticizing designs described using traditional CAD packages. The notion of 'prototypes' has been used to play the central role in such an integration. The development, implementation and operation issues of an integrated system, called IPEXCAD, are described

title	Dynamic Interaction of Solids as a Design Tool
doi	https://doi.org/10.52842/conf.acadia.1990.029
source	From Research to Practice [ACADIA Conference Proceedings] Big Sky (Montana - USA) 4-6 October 1990, pp. 29-40
summary	Architectural form and order can sometimes be described as having dynamic characteristics. To capitalize on this notion, physical qualities (mass, velocity, material elasticity, and friction) are given to objects. The objects are set in motion and allowed to interact at will with each other and their environment. The physical qualities are the rules that govern the outcome of interactions. As a result, interactions can lead to affine transformations (translate, scale, rotate), reformations (topological editing), and/or deformations (geometrical editing) of the objects. The designer can investigate the effects of interaction between dynamic elements, vary their physical qualities, and evaluate the appropriateness of the outcome as a solution to the design problem.

source	New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 103-130
summary	Replacement operations, where an element at any topological level may be replaced by another element at the same or different topological level, are defined. Their potential as design tools which may be incorporated in a CAD system is investigated and demonstrated through the experimental implementation of two such operations in MARCOS, a Modeling Architectural Compositions System. MARCOS has been written in C. It is highly interactive and runs on an Apple Macintosh IIx. The two operations which have been implemented are the face -> volume and volume -> volume replacements. They were chosen for their potential as generators of architectural forms. Examples of architectural compositions produced through the use of replacement operations are also illustrated.

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

summary	This paper describes ongoing research projects on the development of user interfaces for energy software to be used by architects. The paper takes the position that the goal of knowledge-based design software should be to help the architect to visualize the unimagined. In order to approach this goal the unique characteristics of the architectural design process must be understood and used in the creation of software. The two characteristics discussed are: the architectural design process emphasizes synthesis rather than analysis, and the symbols used to transmit knowledge are primarily graphic abstractions rather than alpha-numeric abstractions
