Abstract: Buildings consume 30% of the total energy consumption around the globe and 29% of the energy consumption in Egypt, which in 2022 had a total population of 102 million, out of which 43% live in urban areas. The operation of buildings contributes to around 30% of global CO 2 emissions due to their high energy consumption. Among the efforts made towards improving the energy efficiency of buildings are Advanced Energy Design Guides (AEDGs), building rating systems, codes, and standards. Furthermore, numerous research studies that are either literature review studies, experimental studies, or computational studies addressed the topic of energy efficiency in buildings. In this paper, 124 articles are systematically reviewed with the purpose of identifying the research gap in available research with a focus on Egypt. The identified gap is the development of a prescriptive path for the Egyptian Green Pyramid Rating System (GPRS) energy efficiency category based on whole building energy simulations. Furthermore, recommendations for future research are given based on gaps in the existing literature.
