AbstractThis paper presents the results of a Radiance-based intermodel comparison between the validated Daysim daylight coefficient model and a new standard model for dynamic daylighting simulations (DDS). The new model offers independence from site location and orientation, estimation techniques and simulation applications. The standard data can be used for dedicated daylighting analysis or for integrated building energy/daylighting simulation. Results show that DDS outperforms Daysim, notably in cases where sensors are subjected to sudden changes in solar exposure, e.g. for sensors far from a window.
