Paper Abstract

It is well acknowledged that climate is a vital factor to be considered for building design since it affects both building energy usage and renewable energy generation. In this paper, a comparison study is conducted for a hypothetical grid-connected residential house by applying photovoltaic systems to achieve different types of zero energy building (ZEB) that is located in five representative regions (Beijing, Urumqi, Shanghai, Kunming and Guangzhou) in China. The building demand load is firstly evaluated by degree-day method, then energy usage of the building located in the five locations and the corresponding PV size required are compared. Subsequently, by taking sub-regional feed in tariffs into consideration, the effect of PV cost, the type of ZEB and three key prices are compared on payback period for different climate zones. Results show that Urumqi has the highest load demand (i.e.18,500 kWh per year) and the required PV size is 13.4 kW for designing 1.0ZEB. It is also interesting to find that payback period is reduced by increasing PV-building integration, and the reduction is found to be less than 20% from designing 0.2ZEB to 1.0ZEB. It is PV cost that mostly affects the payback period, followed by FIT_S and finally is FIT_G. With 50% reduction of the three parameters, the payback period is reduced by about 50%, increased by less than 17%, and increased by less than 35% respectively.
