EVOLUTIONARY DESIGN OF RESIDENTIAL PRECINCTS A Skeletal Modelling Approach for Generating Building Layout Configurations

Abstract

This paper presents a ‘skeletal’ parametric schema to generate residential building layout configurations for performance-based design optimization. The schema generates residential building layout configurations using a set of ‘skeletal’ lines that are created based on various design elements and coincident with factors such as walkways, spacing, and setback requirements. As such, the schema is able to generate diverse and legitimate design alternatives. With the proposed parametric schema, a case-study optimization is carried out for a Singapore Housing Development Board (HDB) project. The case study considers a set of performance criteria and produces results with higher practical referential value. The case study demonstrates that the optimization with the parametric schema can improve the overall quality of the design and provide designers with various design options.
