A Methodology of Mapping Interface for Energy Performance Assessment Based on Open BIM

Abstract

Early design phase energy modelling is used to provide the design team with feedback about the impact of various building con- figurations. For better energy-conscious and sustainable building de- sign and operation, the construction of BIM data interoperability for energy performance assessment in the early design phase is important. The purpose of this study is to suggest a development of BIM data in- teroperability for energy performance assessment based on BIM. To archive this, the authors have investigated advantages of BIM-based energy performance assessment through comparison with traditional energy performance assessment; and suggest requirements for devel- opment of Open BIM environment such as BIM data creation and BIM data application. In addition, the authors also suggested on BIM data interoperability system and developed mapping interface.
