As building energy demand and carbon emissions increase, Building Integrated Photovoltaics (BIPV) offers a critical pathway for public buildings to cut reliance on traditional energy sources. Although BIPV provides renewable power, its role in enhancing indoor thermal performance during winter in cold regions remains insufficiently explored. This study proposes the combination of BIPV and double skin facade (DSF) to form a building-integrated photovoltaic-double skin facade system (BIPV-DSF), which can not only provide electricity but also enhance temperature regulation and reduce the loads of the building. Through the simulation of ventilation and air temperature in the ventilation channels (VC) and indoor space, this study demonstrates that: (1) BIPV-DSF increases VC air temperature and enhances circulation, raising the top-floor indoor temperature by 3.7 °C. (2) The installation of baffles within the VC contributes to a more uniform vertical distribution of indoor temperature across different floors. (3) As the heat collection efficiency of the PV panels increases, the indoor temperature can be further improved by 3.3 °C. (4) By connecting VC with the atmosphere, the system can be applied in summer without affecting the indoor temperature. The findings demonstrate that BIPV-DSF improves indoor thermal conditions and informs future building PV applications.
