| Abstract |
The purpose of this simulation study was to improve the performance of daylight responsive dimming system. This simulation study was to analyze the followings. ⅰ) correlation between workplane illuminance and photosensor signal ⅱ) comparison between closed loop proportional and open loop proportional control algorithm in the daylight responssive dimming system. This study used DayDim as a simulation software and four different spatial characteristics of photosensors. Each photosensor has different spatial distributions in the existing photosensor, 0 degree, 30 degree, and 60 degree from nadir. Parameters such as sky condition, seasonal changes, azimuth, photosensor location, and different spatial distribution were considered. The results showed proper photosensor position and spatial distrubution determined by the various parameters. |
