In 2005, the International Energy Agency published that electricity consumption for lighting Consumption for lighting of the sector service. Around Two thirds of the lighting systems now a days are based On technology developed before 1970, and they have lower Performance that the current technology. A complete change of the lighting system and the implementation of control and regulation systems can provide relevant energy savings. This work presents a comparison about the energy efficiency of different control lighting systems applied to office spaces located in Spain. The work is based on DIA-LUX calculations to perform day lighting, lighting systems and lighting controls are compared using fluorescent lighting level distribution on the work plane. [1][2]
