Mapping System between Property of BIM Software and Material of Energy Plus for Open BIM-Based Energy Performance Assessment

Recently, AEC industries have been much research BIM-based energy performance and green building, in Korea. However, Current researches have the lacks of standard guideline for BIM data for BIM-based energy performance assessment and the limitation of interoperability between BIM software. Interoperability is required to Open BIM-based energy performance assessment and it can be exchange, sharing, and compatibility of information between all Open BIM- based software. The purpose of this study is to establish a mapping system between IFC of open BIM standard file format and material of Energy Plus. To achieve this purpose, library and material requirements for the BIM-based energy performance assessment are arranged by investigation and analysis of the researches. A mapping system structure is propose which enables the interoperability between library information of BIM modeling software and material information of energy performance assessment software Energy Plus based on the arranged requirements. Through this research, it is feasible to do the energy performance assessment by the practical use of IFC which was judged as the limitations before, and the application and practical use of mapping system are expected more advanced energy performance assessment software.
