BIM-Centric Daylight Profiler for Simulation (BDP4SIM): A methodology for automated product model decomposition and recomposition for climate-based daylighting simulation

► We develop a method to automatically identify unique daylit spaces in a BIM model. ► Radiance generates spherical maps that are compared for unique geometry and materials. ► The method correctly identified the tested geometric and non-geometric variations. ► The method achieved accuracies in DSerr of 0-0.3%. ► The method also achieved reductions in simulation times of 60-76%.
