Lighting control integrated with daylighting is recognized as an important and useful strategy in energy-efficient building designs and operations. It is believed that proper daylighting schemes can help reduce the electrical demand and contribute to achieving environmentally sustainable building development. This paper studies the daylighting performance and energy use for office buildings using daylight-linked lighting controls via computer simulation techniques. Key building variables affecting daylighting designs are briefly reported and discussed. The daylight factor, indoor daylight illuminance and building energy expenditures were simulated and the reductions of pollutants and greenhouse gases emissions were estimated. The results indicated that daylight-linked lighting controls could save the overall building electricity expenditures and benefit to the environment aspect.
