Abstract
The calculation of utilization factors relies on geometric multipliers to arrive at the distribution factors which give the fraction of the source flux arrives directly at each room surface. There are a number of possible assumptions that can be used to derive geometric multipliers each resulting in different values. This paper explores these differences and estimates the potential differences in utilisation values that may be expected. The key finding is the method in CIE 52 may no longer be appropriate.
