Turpan area is one of the harsher climate areas in the world. It belongs to the continental desert climate in warm temperate zone, the highest temperature is up to 48.3°C in summer (2008) and the lowest temperature in winter is low to -28.9°C (1998). The number of days of wind speed more than 17.0 m/s are 80.3 on average and the annual rainfall is only 16 mm[1]. However, Turpan area is rich in solar energy resources and the annual sunshine hours are 3200 on average. Thus the key to architecture design is how to withstand extreme climate conditions and make full use of solar energy resources. The case integrates active solar systems and passive solar effect is achieved simultaneously, such as shading, ventilation, insulation, etc. The effect such as sheltering from the wind, guiding the wind and shading sunlight is achieved by setting up semi-translucent PV curtain and certain number of cavity on exterior wall. More, the solar ventilation system between the PV curtain wall and exterior wall can take away the heat generated from the PV curtain wall and interior rooms; PV skylight roof can adjust the illumination of the atrium to avoid too low or too high illumination; The extruding PV curtain wall can block sunlight radiation on the underlying window to achieve self-shading.
