Energy Usage Intensity of Bank Building Stock: A Case Study in Pakistan

Abstract

Energy usage intensity (EUI, kWh/m2/year) of a building category helps energy managers and building owners in evaluating the energy performance of their buildings. Banks are energy-intensive buildings, but there is limited research published in this highly energy-intensive building category. In this paper, the energy consumption of 98 bank buildings located in different cities of the AJK region of Pakistan has been critically analyzed and their EUI value has been established. Data were collected through site visits, interviews, and questionnaires. Electricity consumption of each bank branch was normalized using the cooling degree days method and respective annual normalized EUIs were calculated. It was found through analysis that three major factors that drive electricity consumption in bank buildings in Pakistan are building's area, the number of workstations, and the number of automatic teller machines. The EUI of banks in Pakistan has been found to be 222 kWh/m2/yr, which is comparable with the same of eight other countries.
