<p>The present invention deals with light level control for building illumination by controlling electric lights and windows treatment. In an embodiment, the light level is controlled by a control system (2) operatively connected to at least one interior sensor (3) for detecting an interior light level; at least one electric light controller (4) for controlling the light level; at least one window treatment controller (5) for controlling the admittance level of daylight; and a processing unit (7) for handling control setpoints, including an interior light level setpoint. The level of the electric lights and the admitted level of daylight are controlled in parallel by operating the electric light controller and the window treatment controller.</p> |
