An Integrated Scalable Lighting Simulation Tool

Yi Chun Huang
Lighting simulation contribute readily to the synthesis of high performance lighting designs. Unfortunately there exist several issues impeding the pervasive use of lighting simulation, including: Most of the time in preparing lighting simulations is spent towards the input of existing but non-interoperable information between different tools. Lighting simulation tools do not complement integrated building design processes where the design solution is progressively developed in multiple

Disparate tools with vastly different technical approaches available for different stages of the building design process do not allow consistent or meaningful performance comparisons between design versions, and similarly makes design performance progress tracking between design versions difficult. Lighting simulation tools provide radiance and irradiance values as simulation results, and much time and manual effort is required to process these results into operative information, information that is directly applicable in making design decisions. Lighting simulation tools employ outdated rendering techniques that are inadequate in evaluating highly-reflected irradiance, a typical feature in high performance building designs. While there remain other shortcomings in lighting simulation tools as identified by contemporary research3, the issues above relate closely to the overall effort and time-cost factors attributed to using simulation tools, which has been consistently identified as obstacles towards using simulation tools. This research seeks to reduce the effort and time-cost required to conduct lighting simulation by addressing the issues above. Case studies of actual design scenarios are used to establish quantitatively the effort and time costs baselines for comparison. The effort and time reduction goal is structured as the following objectives in a new l [...]
