Due to the fast digital transition of the Architecture, Engineering, Construction, Owner Operator (AECOO) industry, a large amount of information is regularly exchanged between the involved participants. Handling and processing the exchanged data remain a major challenge for many related activities, such as Building Energy Performance Simulation (BEPS). In this context, the interoperability between Building Information Models (BIM) and BEPS models is still an unresolved issue. Many barriers prevent the full integration and data exchange between both models, such as geometry errors and missing data, which require a lot of human intervention. Thus, the process is still regarded as time, effort and cost consuming. In the literature, many works have been done to tackle this problem. In this paper, in the context of the BIM4Ren European H2020 project, which aims at providing BIMbased tools and technologies for fast and efficient renovation of residential buildings, a systematic workflow is proposed to handle the BIM to BEPS process and review the commonly adopted tools and approaches for each of its stages, i.e., from the generation of the BIM model, its geometry check, its data enrichment until its exploitation by a BEPS tools. The proposed workflow is based on the Industry Foundation Classes (IFC) as an information exchange standard for the BIM since it is an open data schema that is commonly used and compatible with most of the BIM software in the market. Finally, a practical approach to follow for a smooth and effective model transfer process is concluded.
