This study demonstrates the development of thermal performance visualization to support design decision making in the early design stage. The objective of this study is to provide the thermal performance results from the building performance simulation tool using Object-Oriented Physical Modeling (OOPM) into Building Information Modeling (BIM). The suggested method allows stakeholders to enable use the BIM tool as a common user interface to visualize the building performance simulation results. To implement the method, 1) a specific BIM tool and its Application Programming Interface (API), and 2) a building performance simulator of OOPM, Modelica Buildings library. Also, an external database is adopted to maintain the building performance simulation results from an OOPM tool. To demonstrate the research method, a prototype called the thermal energy performance visualization (TEPV) is created, which translates the simulation results stored in the external database into the specific parameter in the BIM tool. TEPV enables the thermal energy performance results to be visualized by color-coding building components in the BIM models. The thermal energy performance visualization using TEPV facilitates that stakeholders explicitly inspect the simulation results at the early design stages.
