title Parametric Urbanism: Explorations in Generative Urban Design
source International Conference on Generative Art
summary This paper is the result of several years of research by the Authors into the new field of generative design, as applied to urbanism. Its purpose is to formulate a concept of parametric urbanism and data-driven urban design, and how it departs from existing concepts of urban analysis and resulting design methods. This paper first gives a definition and description of the notion of generative urban design, and its relevance to current the practice of architecture and global political, sociological and economic developments. The difference between dogmatic forms of urban design and new parametric research methods is explained, and the Authors argue the fundamental relevance of using examples of post-colonial large-scale projects. In support of this, the Authors explore the widening field of research into parametric and data-driven architecture and urban design and the history of rule-based and evolutionary design methodologies. The paper illustrates examples of successful research in the field of parametric and rule-based urban design, by the Authors as well as colleagues within the field. It surveys the Authors’ work done at the Architectural Association School of Architecture, at the Hong Kong Polytechnic University School of Design, as well as in practice and research-oriented consultancy. The projects illustrated support the thesis of parametric urbanism by showing its power and versatility when applied to very large-scale projects, in particular within the People’s Republic of China.

title Teaching Creativity with Computers
source CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 307-316
summary Using computers as an aid to architectural design promotes efficiency – of that there is no doubt – but its real merit must surely lie in provoking inventiveness. The medium makes possible the speedy creation and manipulation of images, a holistic, integrational approach to design, the exploration of virtual environments, the real time collaboration in design by individuals at remote sites and so on – these all fall under my heading of ‘efficiency’, since more or less the same ends can be achieved, albeit much more slowly and tediously, by traditional methods. But inventiveness, that’s something different. For comparison, think of the advent of reinforced concrete. In the early years, the new medium was used, roughly speaking, as a substitute for timber beams; but the genius of Le Corbusier was required to appreciate that concrete had fluid qualities which afforded completely different kinds of design opportunities. Can computers likewise revolutionise design? Will new kinds of building get constructed as a result of the advent of computers into the design arena?

summary In the past decades, many attempts have been made to solve the challenging architectural layout design problem such as non-linear programming and evolutionary algorithm (Michalek and Papalambros, 2002). The Mixed Integer Programming (MIP) (Kamol and Krung, 2005) was recently developed to find the global optimal solution. However, the problem can be shown to belong to the class of NP-hard problem (Michalek and Papalambros, 2002). Hence, only the small instances of the problem can be solved in a reasonable time. In order to deal with large problem sizes, this paper utilizes the strong valid inequalities (George and Laurence). It cut off the infeasible points in the integral search space by formulated the disconnected constraints involved with line configurations of three rooms. It is shown to significantly increase the computational speed to more than thirty percents. This exhibits the practical use of the MIP formulation to solve the medium size architectural layout design problems.
