文摘Many kinds of factors that influence rural housing construction in Northern China are analyzed systematically and the connections between them are weighed from ecology and sustainable angles, so that an optimized green house can be built. At the same time, the energy efficient envelope structure and the method of choosing insulation material in the cost of unit thermal resistance are proposed. Integrated quality evaluation by computer shows that thermal comfort in the house would be improved remarkably for the value of PPD drops from 35%-40% to 15%, the rate of saving energy is 51.73%, much higher than the third goal of saving energy in China, and the comprehensive ecological benefit achieves good effect so as to promote the sustainable development of rural housing and community in cold areas of Northern China.
