1. Apparatus for interfacing a lighting system with an automated energy control system comprising:
- means for receiving energy control signals from an automated energy control system; and
means for converting said energy control signals from said receiving means into lamp intensity control signals to control lamp intensity of at least one light output device of a lighting system in response to a power consumption monitored by the automated energy control system, wherein said converting means includes at least one amplifier stage, said amplifier stage having a feedback path which includes a variable resistance.

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.
