An empirical study of performance characteristics of BIPV (Building Integrated Photovoltaic) system for the realization of zero energy building

In this study, we analyze the performance characteristics of BIPV (Building Integrated Photovoltaic) system of Climate Change Research Building of National Environment Research Institution which was designed with the aim of zero carbon building. This building totaling 2449 m2 is consist of five laboratories, PR (Performance Ratio) department, conference room and others, and the area of conditioned space is 1668 m2. In addition, the remaining residual load was predicted to 99,200 kWh when load reducing system was applied such as insulation, exterior shading device and lighting control. BIPV system, which is consist of three modules; G to G (Glass to Glass), G to T (Glass to Tedlar/Crystal) and Amorphous, has 116.2 kWp of total capacity, and is applied to wall, window, atrium and pagora on roof. After the completion of building, the total amount of energy consumption and the gross generation of BIPV system were 104602.4 kWh and 105266.6 kWh through a year from April 2011 to March 2012, respectively. It was evaluated to achieve zero carbon building because the energy surplus was 664.2 kWh. •Our Paper is analyzed through the experimental research on the BIPV (Building Integrated Photovoltaic) system in Korea.•The characteristics of power generation of BIPV system were investigate with 4 polycrystalline modules and 1 amorphous module.•We examine major causes affecting the characteristics of power generation of BIPV system.
