要約(英語): Lighting occupies not less than 30% of electrical power consumption in a typical office building. Lighting control systems have been proposed as energy-saving to reduce electrical power consumption of lighting by supplying necessary illuminance for necessary locations, combined with illuminance sensors and human presence sensors. However, in the closed-loop control of dimming, abrupt changes of target illuminance by information from human-presence sensors might cause flicker of illuminance, and might thereby decrease the office workers' comfort and productivity. This paper proposes a direct-solution algorithm of an inverse problem for open-loop control of lighting to reduce flicker of illuminance. The proposed algorithm computes the setting pattern of the dimming rate from the target illumination distribution on desks using a light influence matrix derived by the point-by-point method of lighting. In this study, we applied a lighting group control system that adopts this proposed method in an actual office. In this paper, we show that the proposed method is effective by experiments using this system.
