• This paper describes a new approximate calculation of interreflection in a room containing fixtures.In the conventional calculation for interior lighting which is based on luminous flux transfer, the number of calculated form factors and hence the computation time increases with the number of surface elements. For this evaluation, the illuminance of each surface in the room calculated vary in fixture type, fixture height, and fixture reflectance.We present results that the approximate values have strikingly good agreements with the exact values for the average illuminance and illuminance distribution of all surfaces, and the computation time is much shorter.
