Abstract: This thesis focuses on a thermal performance indicator, sky view factor (SVF) in an urban design scenario. The relationship between SVF and outdoor thermal performance and the meaning of SVF for urban design are discussed. The preceding algorithms of SVF are reviewed and criticised and a proper solution is developed in GIS platform. A customised tool SVF Extension for ArcGIS is developed and utilised based on our algorithm. SVF is employed as a key indicator of thermal performance in urban environment. Response of SVF to 3-D geometric differentiation is studied through case studies on archetypal spatial configurations and design proposal alternations. Studies on the mechanism of SVF-geometry response bring further implications in interactive design decision making.
