Energy Performance of PV Windows Used in Different Cities of China

In this paper, building simulation software Energy Plus was used to simulate thermal performance, and PV electricity generation of five kinds of glazing system install on the office building in four cities of China, Harbin, Beijing, Shanghai, and Shenzhen, which represent severe cold zone, cold zone, hot summer and cold winter zone, hot summer and warm winter zone respectively. According to the simulation results, the best glazing system for the severe cold zone Harbin and the cold zone Beijing is double PV system, while natural ventilated PV system for the hot summer and cold winter zone Shanghai, the hot summer and warm winter zone Shenzhen. The energy saving rates of the optimal PV glazing system compared to the local SC at Harbin, Beijing, Shanghai, and Shenzhen are 12.3%, 4.9%, 4.8%, 10% respectively.
