Abstract: An energy control system for a dwelling with a plurality of rooms is disclosed wherein said system has a plurality of occupancy sensors, with each sensor adapted to detect the presence of a human being in a room. The occupancy sensors are all connected to a computer with the computer controlling a plurality of dampers that regulate the air flow in the air ducts into the various rooms. Upon the detection of the presence of a human being in a room by the occupancy sensor, the computer sends a signal to the air damper controlling the air flow into that room to open the air flow through that air duct.
