The EU project REVIS (Daylighting Products with Redirecting Visual Properties), was completed at the end of 2000. The project was aimed at: Full angular distribution of solar/light radiation transmitted through & reflected in a daylight component, measured with a goniophotometer equipment & data analysis software, applied on a number of samples representing novel daylight products; a set of indices on the daylight transmitting quality of glazing/sun shading products in terms of their potential to prevent glare, to redistribute the daylight and view through as a basis for future EU standardisation; upgrade database & calculation routines of the EU software tool for the determination of thermal & solar properties of windows, WIS, with detailed daylight distribution data of components & calculated daylight product quality indices.
