ENERGY EFFICIENCY RESOURCE ASSESSMENT AND OPTIMIZATION AT UNIVERSITY OF ENGINEERING AND TECHNOLOGY

This research is the summary of energy usage in UET Peshawar located in Peshawar, Pakistan. Electricity and natural gas are the main consumers of energy in university. About 90 percent of energy is consumed by electric equipment and 10 percent of energy is consumed in gas heaters. Here audit of electric energy consumption is conducted. Electrical energy is consumed by lights, fans and air conditioners. The purpose of energy audit is to provide energy use analysis, and to identify energy conservation measures to reduce energy consumption and operating cost. The scope of research work includes a detailed survey of electric energy cost and consumption per year. The recommended energy conservation measures show technically and economically feasible opportunity to increase energy efficiency of university and reduce the energy and operating cost. In this Energy audit research work several preliminary measures are reported which if implemented will save energy cost of estimated annually. To achieve the estimated savings, initial investment of 69,659,453 PKR must be done to achieve estimated savings of 19,870,359 PKR annually, with energy savings of 907,696 kWh per year. Among these ECMS light retrofitting is very feasible because its payback is less than year. And it saves 2,491,225 PKR annually. The remaining energy conservation measures needs discussion with the administration as the savings is huge, but their initial investment is also high.
