The present study examines the performance of a single zone building integrated with PV Trombe wall(PV-TW) in term of thermal load reduction and electrical energy production by varying PV Glazing types (i.e. Single Glazing, Double glazing, Double glazing filled with gas (Argon)). TRNSYS software is used for simulation in which inputs like climatic conditions, building construction details, thermal properties of materials, detail of PV-TW and orientation of building is inserted. By comparing the results of all three types of glazing it is found that PV Double glazing filled with argon shows significant reduction in mean air duct temperature, hence reduces the PV cell temperature and increases power production of PV panel. Also solar radiation captured by massive wall of PV-TW is reduced by using PV Double glazing filled with argon as compared to other types of glazing, which further reduces thermal load inside the building. © (2014) Trans Tech Publications, Switzerland.
