Electrical energy consumption pre and post energy conservation measures: a case study of one-story house in Dhahran, Saudi Arabia

Abstract

This paper discusses the energy savings from retrofitting a one-story house located in Dhahran, Saudi Arabia. Actual monthly bills were recorded 72 months before and 72 months after retrofitting. The building description and the users' profiles are different before and after the study as indicated by non-A/C monthly electric consumption 1022 kwh and 1772 kwh respectively. In order to account for those differences, electrical consumption attributed by A/C in summer was isolated and compared. The study followed the International Performance Measurement & Verification Protocol (IPMVP) in assessing the impact of energy conservation measures on building energy consumption. The study showed significant savings in air conditioning consumption due to building envelope 40%, and the peak monthly load was reduced by 34% after the retrofitting. The same conclusion can be drawn on the peak hourly demand due to contribution from building envelope.
