summary Despite significant advances in the area of computational support for lighting design, lighting simulation tools have not been sufficiently integrated into the lighting design process. There is a significant body of designers who rely solely on their individual experience and do not use predictive simulation tools. Even when simulation tools are utilized, it is for design verification or presentation rather than for design support. A number of factors are thought to contribute to this lack of integration of simulation tools into the design process: a) Most existing tools rely on the problematic assumption implying the appropriateness of simplified models for the less complex early design and detailed simulation for the more complex later stages of design; b) They do not support an active exploration of design variables to satisfy desired performance criteria; c) They are not integrated with other building performance simulation models. This thesis addresses the above shortcomings by contributing to the field of visual analysis in the following areas, pertaining to the development of active, integrated design and performance simulation environments: - Implementation of a consistent and coherent, physically-based modeling approach, combining radiosity and ray-tracing methods for the simulation of light propagation. - Provision of design support both in terms of evaluation support for interpreting large amounts of computed data with diverse performance indices, and in terms of active design support to explore the relationships between the design variables and performance indices. - Integration of the lighting simulation module within a larger software environment (SEMPER) for the prediction and evaluation of multiple performance indicators (for energy, light, acoustics, etc.) in buildings.
