University contribution in developing country on carbon emission reduction through motion sensor application pilot project on building lighting installation

摘要

The high demand for electrical consumption with current supply corresponds to the high cost of electricity bills. This factor is compounded by the fact that many electric generators in Indonesia still use fossil fuels, which contributes to the high basic generation cost. UBL is one of the universities that aim to be a green campus. One of the efforts to lower energy demand in consumer side is to use the electricity efficiently, such as turning off lights in a room when it's not in use. This method can be simply done by turning the light switches for office and classrooms, but difficult to do in public spaces such as toilets and corridors. Automatic light switches experimentally installed in sample toilet room prove that electricity consumption from the lamps can contribute to 63% reduction from the total weekly energy that translates into 10.95 tons/year of Green House Gas emission reduction.
