Energy Efficient Modelling of USPCAS-E UET Peshawar Building using eQUEST Software

Abstract

Energy consumption by the domestic sector in Pakistan is 46% which is one of the highest use by any country. The Government of Pakistan has planned to save 3 Million Tons of Oil Equivalent (33,000 MW) by 2025 through energy efficiency and conservation practices. Conserving this chunk of energy without effecting quality of life and measurements to improve buildings energy efficiency is a problem to be resolved. Several studies have been conducted to evaluate the performance of implementing various sustainability measures in existing buildings via various simulation tools. The purpose of this study is to analyze a fully functional building and find the possible cost effective measurements that can be taken to conserve available energy potential using eQUEST software. The building under study is United States Pakistan Center for Advance Studies in Energy (USPCAS-E), University of Engineering and Technology (UET), Peshawar. An energy efficient model of the building is calibrated in the study in comparison with the actual billing data. The simulation results are very close to actual energy consumption of the building. The overall results indicates that the building is state of the art building with almost all necessary measures already considered but some policy propositions are needed. HVAC and lightning are the significant energy users (SEUs) here and there is a substantial potential for improvement which is presented. Some changes are made in the building occupancy scheduling and some regulations are presented for the occupants behavior change towards energy use.it.
