**5. Conclusions**

In this study, an air-type BIPVT collector was manufactured and installed in a realscale experimental house, and its electrical performance and temperature characteristics were investigated and compared with a BIPV system through experiments. In addition, the effect of energy savings was analyzed when the BIPVT was connected to an AHU system. The key findings are as follows:


Based on these results, the performance of the BIPVT collector and related energysaving effect by connecting to an AHU system in the building can be seen. It is expected that this study can be used as a foundation for further study on building systems integrated with BIPVT collectors.
