Construction of Intelligent Lighting System Providing Desired Illuminance Distributions in Actual Office Environment
An Intelligent Lighting System providing desired illuminance distributions at minimum electrical power was constructed in the actual office environment. The place of construction is the Area Planning Office in the headquarters building of Mitsubishi Estate Co., Ltd. in Otemachi, Tokyo. The floor area is about 240 square meters, and 26 lighting fixtures and 22 illuminance sensors are installed. One lighting fixture consists of neutral fluorescent lamp and light bulb fluorescent lamp, and the color temperature can be changed for each fixture. These devices are connected with the control PC and operate with an optimization algorithm. With the constructed system, individual illuminance was successfully provided to each office worker.
