20130166265 | METHOD FOR SIMULATING INDOOR ILLUMINANCE - Described herein is a method for simulating indoor illuminance which includes preparing an intrinsic optical property function of a bidirectional transmittance function and a bidirectional reflectivity function based on values actually measured for each plate-shaped optical member; for a skylight constructed by combining a plurality of those optical members, creating an optical physical model based on the intrinsic optical property function and the construction mode of each optical member constituting the skylight; calculating the skylight light distribution data for daylight, which is introduced through the skylight, by using the optical physical model; and simulating the indoor illuminance, which would be provided by actually installing the skylight, on the basis of the light distribution data. The simulation is performed on a computer system which has stored the intrinsic optical property function of each optical member in a database. | 06-27-2013 |
