Electrical Energy Audit and Analysis of Energy Conservation Opportunities at University Buildings

Buildings are one of the major consumers of energy in Pakistan. A case study of electric power consumption in the main campus (i.e. sector-A) of Quaid-e-Awam University of Engineering, Science and Technology, was carried out. This research work was mainly based on the energy audit and analysis of conventional energy conservation measures such as using daylighting and minimizing wastage of energy by reducing the usage time of electrical appliances. The luminance level could be maintained by opening windows installed inside the classrooms. Each classroom and office consisted of two to six windows. The daylighting increased the illumination level and reduced the consumption of electricity by switching off the lighting appliances. The different parameters like indoor temperature and illumination level and amount of electricity saved in kWh were recorded by using various meters. It was found that using the daylight method could save 65,923.52 kWh/year and can save Rs. 922,929.28 pkr (Pakistani rupees).
