Abstract

Educational buildings are the most suitable type of building for the application of energy audit. Such measures can promote sustainability and ensure a comfortable and healthy environment for educational purposes. This study aimed to assess energy efficiency and conservation of the College of Engineering specifically the lighting system of the building. A walkthrough audit was made to acquire preliminary assessment on the building. A luxmeter was used to measure illumination (lux). The study showed that the illumination levels did not meet proper standards. Through data logger and theoretical calculations, it was determined that lighting system consisted 44% of total power consumption. These led to the development of a new lighting system (room E209 selected as a sample) composed of F28T5 lamps which improved lighting levels and saved more energy than the old F40T12 lamps. Through calculations, the new lighting systems showed an annual savings of Php5708 for room E209 alone with payback period of 2 years and 3 months.
