The sensor unit senses environment states within building. The database stores data related to the environment states of the building. The central control unit controls devices related to the environment of the building on the basis of the stored data of the database. The mode setting unit sets a operation control command of a central control unit. The illumination control unit controls an illuminating unit(180) according to the command of the central control unit on the basis of the setting states of the mode setting unit.</p> |
