画像センサによる照明個別制御の有効性検証

抄録

In this paper, we aim to find out the energy efficiency of an individual lighting control system using image-based motion sensors, which recognize occupants with image recognition technologies, by comparing a lighting control system using conventional passive infrared sensors (PIR sensors). We evaluated the actual energy consumption by the lighting control system using the two types of sensors over 12 weeks in 2 office environments and simulated energy consumption based on the record of the sensor values. Our result suggests that the individual lighting control system using the image-based sensors have reduced the energy consumptions by more than 17.3% (0.83 kWh) per day on median. In addition, we analyzed the advantages and disadvantages of the individual lighting control system based on image-based sensor in more detail. One of the disadvantages was misdetection of occupants, which may increase energy consumption. From estimation based on simulation, we consider that the effect of misdetection may be reduced by time-scheduling control.
