Abstract

Building integrated photovoltaic (BIPV) plays an important role in current sustainable building design. However, the issue is significant when by using BIPV under direct sunshine, temperature of PV panels increases and the power generation from PV reduces. An appropriate solution of this problem is to design a BIPV structure which can remove its own heat gain and induce indoor natural ventilation simultaneously. In this study, ventilated BIPV has been designed and developed with a double skin roof structure and covered ridge with sidewall Opening (CRSO). The influence of CRSO and BIPV opening locations towards the outdoor and indoor with different outdoor wind velocities on flow structures Are analyzed numerically, which shows that flow structure near the CRSO have significant influence on natural ventilation performance.
