A smart lighting control to save energy

In Europe the amount of the electrical energy used in illuminating the interiors of medium and large buildings is considerable of about 40%. Energy saving actions could follow two basic directions: efficiency and effectiveness: efficiency, by new more performing equipment (lamps, control gear, etc.) and by utilization of improved lighting design practices (localised task lighting systems); effectiveness by improvements in lighting control systems to avoid energy waste and by adopting a technical building management system (maintenace and metering). By controlling the lighting in such a way that the lighting level is always accurately matched to the actual need allows to save on the energy costs and to improve the human comfort and efficiency. Establishing an integrated lighting control concept is a very important part of the lighting design process. Directly controlling and managing energy consumption it is possible to reach high effectiveness in energy management.
