The optical performance of redirecting daylight materials under given outdoor illumination conditions is characterized by mean of virtual goniophotometry, and results are expressed as light source equivalent distributions that can be then used as input to daylighting simulations. Such a concept has been practically applied to the SerraGlaze product and will be extended with real case experiment.
