초록

This study investigates the effects of daylight dimming control systems for a small office space with a solar panel under variety of daylight conditions. Computer simulations using Radiance software were conducted and consecutive computation procedures were employed to determine the final light output by the control system. Results indicate that the desk 1.5 m away from window was overshot and revealed limitations for daylight dimming controls.
The desk 3.3 m away from window was effective for the applications of control system due to stable daylight on the desk. The blind with 45 degree of tilt angle failed to provide a target illuminance showing excessive dimming levels and insufficient daylight. Lighting energy savings achieved by the control system under clear and overcast sky ranged from 32.92 to 78.89% and from 21.19 to 40.65%, respectively. Linear prediction models between the desktop and photosensor illuminance due to daylight were acceptable under a significance level of 0.05. The linear relationships between them under overcast sky were stronger than that of clear sky.
