Abstract
The present invention is directed to providing building automation systems which can effectively control light output of a building in a manner which can significantly reduce power consumption, yet which goes virtually unnoticed by building occupants. Exemplary embodiments are directed to using existing building automation systems to control the dimming, rather than the turning off, of selected artificial lighting. Further, exemplary embodiments are directed to using the conventional relay network of existing building automation systems to control the dimming of the artificial lighting.
