Abstract
A cost effective illumination control system calculating motion and daylight or surrounding light inputs, particularly in large structures where the light distribution is not uniform across time. The system divides the structure into zones each having input capability with regard to occupation and background light levels. Each zone being able to make independent decisions with regard to control of lighting levels in the zone, yet the zones being able to cooperate in a coordinated fashion to provide uniform lighting to the structure as a whole.
