A Study on Determination of Poiling Period of Daylight Responsive Dimming Systems

광센서 조광제어시스템의 폴링주기 결정에 관한 연구

Recently, energy depleting problem have risen seriously. Many studies of daylight responsive dimming system for saving of lighting energy in office buildings have been done actively. Most of studies are focused on the accuracy. However if the variation of dimming levels is changed too often, occupants would feel uncomfortable. First, illuminance changes which occupants couldn't detect are studied through analyzing foreign studies. Second, workplan illuminance from daylight in each sky condition is measured. Because the dimming level In daylight responsive dimming system is dependent on the workplan illuminance from daylight. In conclusion, the most appropriate polling periods to daylight responsive dimming system for occupant's visual comfort was determined.
