Abstract:An energy audit is a study of a plant or facility to determine how and where energy is used and to identify the measures for energy savings. Generally the institutes, library buildings, offices, rooms etc. are well designed without looking towards energy efficient lighting system. But during energy accounting, these buildings consume more energy as the energy required by energy efficient structure design for the same. This research paper aims at the identification of lighting based energy losses of saraswati complex (Library) of DCRUST Murthal, a state government funded university. This research paper implements the concepts of lighting methodology for calculating the lighting parameters manually that directly calculate the performance of the lighting system parameters in a single excel sheet. Finally the energy efficient measures are proposed for improving energy savings &illuminance level.
Keywords: lighting, energy audit, energy efficient,methodology, lux meter, circuit watt, illuminanceetc.
