A comparative analysis of building energy performance assessment on campus buildings (case study: Universitas Bangka Belitung)

Based on the sector, public buildings construction will become rapid development. Thus, good planning is needed to achieve a green and sustainable building. The necessity of well-planned campus buildings is required in establishing a new study program. UBB campus has a typical design and layout. It is apprehensive that the ineffective design concept in the construction will have a negative impact and waste energy. This study aims to evaluate the design of UBB campus building in terms of assessing the thermal and energy performance building on two building designs (Babel IV and Timah I). The design assessment employs the Rayman, CBE Thermal, OTTV calculation, and EDGE building. The analysis will be managed comparatively with several applications, to obtain significant factors. The results of this study shows that energy-efficient with a green concept can be applied in Bangka Belitung. However, the UBB campus building has not fulfilled the green building standards. In addition, it was found that the orientation and the WWR ratio can reduce the energy load on the building significantly.
