Abstract：
The new type building material residential demonstration zone is strictly constructed according to German passive house standard in Rizhao, ensuring the sealing of external building envelope for the whole building and reducing energy consumption, its heating energy consumption is seventy five percent lower than routine building. The external window indoor pastes waterproof vapor membrane, it can prevent water vapor permeation indoor; the external window outdoor pastes waterproof breathe membrane, it can timely vent water vapor to outdoor, avoiding condensate water to destroy thermal insulation layer. The sun-shading system can reduce solar heat gain coefficient for 0.5 to 0.1, the heating system efficiency of ground source heat pump unit comparing with gas-fired boiler increases by 50% on average. The chilled beam of air-condition is uniform blowing distribution and don't produce condensate water. The heat exchange efficiency of fresh air handling unit reaches up to 85%.
