A statistical review of a decade of residential energy research in Egypt

To alleviate burdens to the Egyptian national electricity grid, there have been growing research efforts throughout the previous decade to reduce building-associated energy consumption. In the present contribution, a systematic and statistical literature review is undertaken, focusing on studies seeking to improve energy-efficiency in Egyptian residential buildings. Identified articles are analysed by breaking then down into five categories describing variables manipulated, methodology and types of analyses, performance objectives, study locations and residential case studies analysed, with the aim of unravelling key research trends and making pertinent gaps evident. The review indicates significant overlaps in the scope of enquiry; results highlight a simulation-based methodology, scenario analysis and exploration of energy performance, excluding economic and environmental performance objectives are repeatedly undertaken in 75% of articles. Based on these results, operational guidelines are proposed to support future research and broaden the scope of enquiry of Egyptian residential energy research. (C) 2022 The Author(s).
