# Thermal Performance Visualization Using Object-Oriented Physical and Building Information Modeling
## 5 Conclusions  
Our approach demonstrates a new method that supports an improved sustainable design process by providing visualized thermal BEPS for BIM users. The prototype developed is expected to benefit sustainable building energy design by visualizing thermal performances of building components. Moreover, the TEPV prototype shows BIM capability, serving as a common user interface for designers to explicitly check BEPS results by visualizing building components for the building design process. In addition, our method facilitates architects to identify the specific building objects most critical to thermal efficiency by investigating color-coding building components at the early design stages. Consequently, our prototype facilitates architects becoming better informed, improving their sustainable designs in the early design stages, where the impact of design decisions is critical to

building thermal energy performance. Current prototype only represents the loads simulation results into opaque building components such as walls, floors, and roofs, while the developed framework [12] of OOPM\(-\)BEPS can represent building component\(-\)based simulation results. We will demonstrate thermal performance visualization of the non\(-\)opaque building component in the future research. Also, in near future, we will investigate additional OOPM\(-\)BEPS results such as indoor air temperature, solar radiation, infiltration, and energy performance of the self-shading building envelope in our prototype.
