In the 21st century, global energy security is a critical concern. Buildings contribute to over 40% of the worldwide energy consumption, primarily due to heating and cooling, resulting in a third of greenhouse gas emissions. The residential sector accounts for 25% of global electricity consumption, and in the Arab Mashreq and Maghreb (AMM) countries, the residential sector consumes around 41% of the total electricity. Existing residential buildings constitute a significant portion of the building sector, playing a crucial role in the overall performance of the building sector. To address this issue, it is essential to invest in the energy retrofitting of existing unsustainable residential buildings. This study aims to provide a comprehensive critical review of the literature on residential buildings’ energy retrofitting trends in the AMM countries. Using a keyword-based search, 41 relevant studies were identified and critically analysed to identify gaps in the literature, benchmarking against global retrofit studies’ trends, including the absence of top-down and bottom-up physical approaches and the limited use of modern tools like BIM. Additionally, there is a significant lack of studies that present measured and verified case studies of implemented energy retrofitting projects. The study concludes with recommendations for future research to bridge the gaps in the literature.

Thermal refurbishment and retrofitting building envelopes with passive measures such as the optimisation of opaque and transparent fabric performance may play a key role in reducing cooling and heating load and promoting building energy efficiency. Furthermore, to reduce the embodied carbon impact of the building, the refurbishment measures need to consider the use of low-carbon building materials. This paper investigates ways to thermally future-proof typical Libyan houses using biobased materials. Several typical Libyan houses were monitored for one year to investigate the heating and cooling energy use and to thermally retrofit the building envelope. A digital twin was created in the DesignBuilder software using the real building data of one building for digital model calibration. Finally, multi-objective optimisation was carried out with low-impact biobased materials for insulation, including camel hair, sheep wool, and date palm fibre as well as using other optimisation variables such as shading and glazing types. The study reveals that thermally upgrading the building roof and wall with insulation materials and upgrading the windows with energy-efficient glazing and local shadings can achieve a reduction in cooling load from 53.51 kWh/m2/y to 40.8 kWh/m2/y. Furthermore, the heating load reduces from 19.4 kW/m2/y to 15 kW/m2/y without compromising the standard annual discomfort hours.
