Abstract
A load control system for a building having a lighting load, a window, and a heating and cooling system comprises a lighting control device for controlling the amount of power delivered to the lighting load, a daylight control device (such as a motorized window treatment) for adjusting the amount of natural light to be admitted through a window, and a controller for adjusting a setpoint temperature of the heating and cooling system to thus control a present temperature in the building. In response to receiving a demand response command, the controller controls the lighting control device, the daylight control device, and the heating and cooling system so as to decrease a total power consumption of the load control system. The load control system may comprise a controllable switching device for disconnecting power to or disconnecting the control lines to one or more components of the heating and cooling system.
