주간의 인공조명 조절방식에 따른 조명 에너지의 평가방법

Lighting is one of the largest energy consumption in commerctial buildings. For saving such energy, effective lighting control systems have been suggested. A major purpose of the lighting control systems is to provide suitable illumination levels for visual performance while minimizing electrical energy during daytime. So, this paper is a preliminary theoritical estimation process of lighting energy by control systems- on/off switching, multi-step switching and continuous dimming.
