Abstract: In the light of local carbon targets responding to climate change and global warming, countries need to curtail the energy consumption of their building sectors. Existing building stock represents most projects in that sector and energy retrofitting of existing unsustainable buildings is, hence, essential in achieving the above goal. Yet, energy retrofitting is a multiplex process plagued with inefficiencies, resulting in the low rates of uptake in Australia and globally. Using Building Information Modelling (BIM) can accelerate energy retrofitting and presents numerous advantages if applied properly. Many studies have presented BIM-Energy Retrofitting Frameworks (BIM-ERFs) that successfully adopt BIM for the ER process. However, the BIM-ERFs in these studies appear to be dispersed in nature, with varying BIM implementation level, scope, software(s), interoperability, and analysis methods. This dispersion can be counterproductive for BIM implementation in retrofitting. The authors identified a need for further research that critically examines and evaluates the current BIM-ERF approaches. In response, the paper presented here fills a knowledge-gap by critically reviewing 64 recently published BIM-ERF studies via a systematic literature review. The review reveals that BIM-ERFs are comprised of four main stages including pre-retrofit, design and analysis, construction, and post-retrofit stages. When critically examined, it is found that most of the studies are focused on the design and analysis stage using BIM and energy simulation and fail to sufficiently address the other critical stages. Accordingly, this review presents the future research priorities for studies to adequately address issues in all BIM-ERF stages.
