This study integrates photovoltaic (PV) system, building structure, and heat flow mechanism to propose the ventilated building-integrated photovoltaics (BIPV) walls. Energy-saving potential of the ventilated BIPV walls was investigated via engineering considerations and computational fluid dynamics (CFD) simulations. The results show that the heat removal rate and indoor heat gain of the proposed ventilated BIPV walls were dominantly affected by outdoor wind velocity and airflow channel width. Correlations for predicting the heat removal rate and indoor heat gain are introduced. After considering building construction practices, this prototype was transformed into a curtain wall structure that complemented the design of the overall construction.
