EUROPEAN RESEARCH PROJECT RE-VIS,DAYLIGHTING PRODUCTS WITH REDIRECTINGVISUAL PROPERTIES

摘要

The European RTD project REVIS, Daylighting products with redirecting visual properties (contract JOE3-rnCT98-0096), started in October 1998 and was completed by the end of 2000. The project was coordinated byrnTNO. The presentation highlights the objectives, means and some of the main results.rnThe main results are: Measurement data of the full angular (bi-directional) distribution of solar/light radiationrntransmitted through and reflected in a daylight component (glazing, sun shading), measured in goniophotometerrnequipment and data analysis software, applied on a number of samples representing novel daylight products. Arnset of indices on the daylight transmitting quality of glazing and sun shading products in terms of their potentialrnto prevent glare, to redistribute the daylight and to view through as a basis for future European standardisation.
