This paper reports the status of new hybrid simulation for daylight analysis method under development. The method combines both full-scale physical measurements and computational techniques, providing analysis results of complex fenestration system (CFS) with increased realism while keeping costs in check and, for the first time, the repeatability of excitation conditions at fullscale. The simulation method divides the physics of daylighting into the two primary components: direct and diffuse light. Preliminary results of the diffuse component of the system and the current state of the heliodon is presented in the paper for a novel CFS known as translucent concrete panels for energy-efficient building envelopes.
