Assessment of Energy Saving Potentials in Covenant University, Nigeria

ABSTRACTIn this study, an energy audit was conducted at Covenant University in Nigeria looking for ways to reduce energy costs. Results show that of the total university electricity energy demand, space cooling and lighting have the highest electrical consumption (29%). In academic buildings, space cooling consumed the maximum power (49%), while lighting consumed the most power (39%) in staff quarters. Annual energy and cost savings for replacement of traditional fluorescent lights (FLTs) and incandescent bulbs with compact fluorescent lamps (CFLs) in student hostels and staff quarters are about 394 MWh, N4.8 million (
