Abstract

Passive solar systems can be integrated with conventional buildings to reduce energy consumption. Various solutions are employed to enhance the performance of these systems. This study investigates the effectiveness of a photovoltaic (PV) Trombe wall combined with phase change materials (PCMs), taking into account climate change in Mashhad. The research is conducted through simulations. By altering the placement of PV cells and experimenting with different PCMs, the optimal performance of the Trombe wall was identified for both cold and hot periods of the year. The findings indicate that utilizing PV cells on glass with C18 PCM on the wall yields the best performance throughout the year. The highest indoor air temperatures recorded in April were 27.09 °C for the brick and 27 °C for the concrete Trombe wall. It was observed that the Trombe wall without PVs and PCMs absorbs more heat. Under the RCP2.6 scenario, the proposed Trombe wall is projected to remain efficient for the next 70 years. Study of RCP2.6 and RCP8.5 scenarios revealed that during both cold and hot periods of the year, thermal comfort provided by the Trombe brick wall surpasses that of the concrete wall, which is −0.261 and −0.322 in July.
