The purpose of this study was to analyze the electrical and thermal characteristics of the various types of ventilating BIPV systems. Compared with the conventional top and down block off type, the top and down open BIPV system using natural stack effect and mechanical ventilating type has potential to improve the conventional block off type BIPV systems’ in-site various problems like PV cell high temperature. These kinds of conventional block off BIPV have low efficiency power production and shut-off at the junction box for high humidity ratio environment condition. Hence, it is critical to compare the PV cell temperature, efficiency, and power production between the mechanical ventilating type BIPV and the conventional block off and natural ventilating type BIPV system. For this purpose, the IPMVP OPTION D analytical program TRNSYS and the type 567 model based on the Sandia model were used and the PV cell temperature, PV electricity efficiency, and BIPV system useful energy rate were estimated with different Reynolds number cases, such as the natural ventilation and the forced mechanical ventilation flow. As for results, first at the BIPV electrical point of view, the Reynolds number increasing led to lower PV cell temperature, higher PV efficiency, and higher PV power production. Especially, the maximum BIPV cell temperature occurred at 12 am on October 3. At that time, at each case-1 (Reynolds number 0) and case-9 (Reynolds number 30,304), the respective PV cell temperature value showed 67.6℃ and 36.3℃, respectively, and the corresponding PV efficiency indicated 8.0% and 12.3%, respectively. The individual PV production power value marks were 59.5 kW and 91.9 kW. Second, at the PV thermal view point, increasing Reynolds number induces more annually BIPV building heating useful energy. Particularly at each case-1 (Reynolds number 0) and case-9 (Reynolds number 30,304), the respective BIPV building heating useful energy showed 0 kWh/yr and 7,514 kWh/yr.
