Abstract

This research proposed an automatic lighting control system in building using daylight and artificial lighting integration for energy savings. The proposed control system is used to automatically reduce or increase the light output of the T8 LED lamps to illuminate the room, where there is an illuminance from the outside coming into the room, to achieve a set value. When testing, the lighting control system was installed with T8 LED lamps in the 6.3 × 8.8 × 3 meter-classroom for 20 days from 9:00 a.m. to 4:00 p.m. (except Saturday and Sunday). The electric power consumption was measured and was compared with the one of fluorescent lamps and T8 LED lamps that were not installed in a lighting control system. The experimental results showed that T8 LED lamps that were installed in an automatic lighting control system consumed electric energy of 20.46 kilowatt-hours; fluorescent lamps consumed electric energy of 60.53 kilowatt-hours; and T8 LED lamps that the automatic lighting control was not installed consumed electric energy of 33.02 kilowatt-hours. This means that the electric power consumption of T8 LED lamps that were installed in an automatic lighting control system was less than the power consumption of fluorescent lamps and T8 LED lamps that were not installed in an automatic lighting control system 66.19% and 38.03%, respectively.
