The rapid technological advancements in the construction industry have underscored the need for tools and regulations in sustainability assessment. To improve the sustainability of retrofits in the built environment, it is essential for governments in Sub-Saharan Africa to establish policies and legislation supporting the effective integration of Building Information Modeling (BIM). However, literature on BIM adoption in Sub-Saharan retrofit projects remains limited. This study reviews 40 articles published between 2009 and 2022 in reputable built environment journals, analyzing the role of BIM in enhancing sustainability evaluations. The findings highlight that most studies focus on environmental sustainability (71%), with economic (15%) and social (11%) aspects less emphasized. Additionally, sustainability evaluation models often neglect critical regenerative factors, such as biodiversity, water conservation, land use, socio-economic impacts, and acoustics. These insights suggest a need for integrating emerging technologies, such as the Internet of Things (IoT) and blockchain, to strengthen sustainability assessments in retrofit projects.
