In this study, ventilated BIPV (Building Integrated Photovoltaic) has been designed and developed with a double skin roof structure to introduce indoor ventilation and provide itself with environmental control. The influence of BIPV opening locations (toward the outdoor and indoor) with different wind velocities on PV heat dissipation, air exchange rates and average indoor temperature are analyzed, via CFD numerical simulations. It shows that, in different wind conditions, ventilated BIPV roofs with outdoor and indoor openings have different capabilities in air exchange and thermal environment. Both designs proposed in this study can achieve adequate indoor thermal environments and maintain PV panel temperatures within an acceptable range.
