Retrofitting an existing structure enhances its energy efficiency, aesthetic appearance, and thermal comfort while also reducing the building’s energy costs. Buildings account for 40% of global energy consumption, which is al-so responsible for CO2 emissions than any other economic sector. The achievement of high energy performance, thermal comfort, and cost optimi-zation for new buildings has become more realistic with the rise in the use the innovative technology in building construction. However, studies have increased the contribution of smart technology in retrofitting a building, but the extent of the work remains unmapped. Hence, the domain knowledge must be documented, especially regarding the global perspective of smart technology in retrofitting the building. Therefore, this study critically re-views existing literature on smart technology use in retrofitting using a sci-entometric analysis approach. VosViewer software was employed to analyze the retrieved research corpus. Findings revealed momentum in retrofitting studies in 2017. The smart technology most used in retrofitting is smart me-ters, heat pumps and photovoltaics. The scope of the study is limited, with the majority of studies focusing on trade-offs between energy costs and thermal comfort. Also, the Energy and Buildings journal is the most cited and published research outlet in building retrofitting with technologies. The United States was identified as the most productive nation in the subject matter, while South Africa is the most productive country in sub–Saharan Africa.
