Description
The objective of this study is to identify the effects of mirror duct system on energy savings for luminaries. The results of the experiments showed that more than half of the subjects judged the room was bright when the illuminance on the desk from mirror duct system was higher than 100 lx. Half of the subjects judged ceiling luminaire could be turned off when the illuminance on the desk was higher than 100 lx in the case of relaxing. On the other hand, about 80% of the subjects always switched on the luminaire regardless of the illuminance on the desk in the case of reading.
