In this study, the thermal properties of BIPV applied to glass façade are focused. There are few instances of BIPV use at domestic and overseas, but it is significant to tackle BIPV as urban architecture because the application of BIPV to glass façade can contribute to power generation, the reduction of thermal load in the room an can also alleviate sensible heat load to the outside. According to the Energy Conservation Standards in Japan, thermal properties of facade are evaluated by PAL*(Perimeter Annual Load) for each area and each building application. Since the calculation of PAL* requires the thermal transmittance (U-value) and the Solar Heat Gain Coefficient (SHGC:G-value), the use of BIPV should increase if thermal properties of PV module are grasped. PV includes crystalline silicon type, thin film type, other types (organic thin film, dye sensitization, perovskite) etc. and crystal silicon was targeted for its high adoption record. Therefore, an additional test was conducted for the purpose of grasping thermal performance according to ISO standard. In this paper, the experimental results of thermal properties of mono crystal silicon PV module are reported.
