Reviewing the recent studies on decarbonization policies in the built environment, tools, and techniques along with the recent progress on BIM and LCA integration area, limited practices are witnessed related to implementing innovative technologies into decarbonization policies issued by public services. One challenge lies in the lack of methodological details to define the framework of BIM and LCA systematically with a view to promote decision-making in the construction sector and to protect the built environment. The most recent reviews identified the advanced strategies and gaps in the integration of BIM and LCA, where they assessed the recent studies based on the type of input data, data exchanging process, output results along with method of storing environmental information. The review outcomes show that BIM-based LCA studies mostly focused on manual and semi-automatic solutions at the early design stages. It is also specified that all design variations still have not been addressed in order to enhance the validation of the results to complete the automation of the LCA process. A comprehensive approach must fully address GHG emissions benchmarking or one that considers the whole life cycle and includes embodied carbon, operational carbon, and carbon released at the end of the service life of the asset. Therefore, a consistent data format and similar naming convention for both kinds of data should be established when a link between BIM and LCA tools is to be set. During the data transition, information from BIM models is transferred into LCA tools to determine the LCI results.
