This project addresses the feasibility of two basic methods for saving electric energy. The goal of the works is to determine the viability of motion detector and remote controller of air-conditioner to reserve electric energy. After calculation and analysis, it was learned that for building with good thermally insulation, the intermittent on/off operation on air-conditioner could result in about 50% reduction on the consumption of electric energy; similarly, installation of motion sensor in places demanding for great electric lighting would assist people in saving electric cost in less than 3 years. In conclusion, the paybacks of both of the methods are desirable, which indicates the worthiness of investment on these two means of saving electric energy.
