Building-integrated photovoltaic(BIPV) systems can operate as a multi-functional building components, which generates electricity and serves as part of building envelope. It can be regarded as a new architectural elements, adding to the building's aesthetics. Besides of these benefits, the application of PV systems into school buildings tends to play an important role in energy education to students. In this context, this study aims to analyse the applicability of PV systems into school buildings. For an existing school building, four types of BIPV designs were developed; rooftops, wall-attached, wall-mounted with angle, and sunshading device. Based on energy modeling of those BIPV systems, the whole 60.1kWp rated PV installation is expected to yield about 65.6MWh of electricity, that is about 50% more than the annual electricity consumption of the school, 44MWh. It was also found that the applicability of the PV systems into the school building was very high, and the rooftop systems with the optimized angle was the most efficient in energy production, followed by sunshading, wall-mounted with angle and wall-attached. It concludes that school buildings have a reasonable potential to apply PV systems in the aspects of building elements and electricity production.

This study examines building's power consumption unit cost and Building Integrated Photovoltaic (BIPV)'s generation efficiency and load rate with the subjects of university dormitory buildings in order to suggest foundational data for new and recycled energy use and management to plan and operate university dormitories afterwards. Thereby, this research gained the following findings. 1. The quantity of solar radiation and efficiency change in the BIPV system applied to the research subject buildings after the lapse of time was averagely 8.7%, and it is thought that temperature increase determines conversion efficiency with the influence of surrounding outside temperature and the module's temperature. 2. The generation efficiency of the BIPV system in the research subject buildings was averagely 10.9%. In May, it was 13.9%, and in January, it was the lowest as 10.25%. Considering the fact that power consumption reduces during an intermediate period, it will be necessary to establish measures for equipment and power consumption load balancing. 3. The monthly load rate of the BIPV system was averagely 4.09%. In May, it was the highest as 4.94%, and in July, it was the lowest as 3.24%. 4. It is intended to conduct constant follow-up research on estimating university dormitory building's power consumption unit cost and examining the generation efficiency and load rate of the BIPV system.
