Greening existing buildings through Building Information Modelling: A review of the recent development

The use of Building Information Modelling (BIM) for green retrofitting is a recent development due to its integrated solutions for evaluating and monitoring the environmental sustainability performance of existing buildings. It can be implemented throughout different stages of building life cycle using centralized digital models. However, the actual applications of such technology are still scarce and require further study and verification. In this paper, a systematic review of the recent development of BIM was conducted on two related areas: (a) existing buildings' sustainability performance and (b) green retrofitting. The review highlights that little work has been conducted on these two areas concurrently which is mainly at the exploration stage. The results further reveal common BIM sustainability tools, performance parameters and design parameters in the recent research on the green retrofitting of existing buildings. Furthermore, a research framework has been developed to fill the research gaps and future needs in the implementation of BIM for green retrofitting, including data acquisition techniques, integrated process, unified platform, data interoperability and management, level of automation, design alteration as well as auto data feedback. This paper provides new insights into both theoretical developments and practical or technical aspects of BIM in fostering a complete green retrofit ecosystem.
