Decision support for window design : a computer-based prototype

Abstract

Several approaches have emerged for the integration of computer aided design support systems and architectural design processes. However, architects have yet to see such a system that is not only useful for producing construction drawing, but also useful in earlier processes of the design, for example, in the preliminary design stage, in the use of architectural referencing, and in evaluation of alternative design solutions. The design support system that I propose and implement in this thesis, is one that incorporates traditional design tools with computer technology. The system is capable of evaluating designer's decisions and automatically translating his or her decisions to a 3-D model; it provides the designer with an interactive means to access visual images and textual data; it is also, much like the knowledgeable expert, capable of evaluating and manipulating the form, and engaging the designer in constructive discussion about the form until he or she is most satisfied with it. Acknowledging the challenge of implementing such a system in a complex design environment, this thesis focuses on a small prototype model. The prototype model illustrates all the issues that I have presented and implies a much broader structure that future implementation work can be expanded from. The system is called LWINDOW - a prototype design support system for designing library window. The thesis addresses three major issues, i.e. the idea and rationale behind such a system, the implementation strategies and examples, and lastly, the evaluation and future trends. This thesis aims to contribute to the development of computer aids for the preliminary phases of design. I hope that as a result of this prototype design support system, the environment of the integrated design support system for architects will no longer be something the experts talk about, but will become a realistic system that can eventually aid architects in their every day practice.
