摘要：In China, a new "Design standard for energy efficiency of residential buildings (for cold region)" was introduced in 2006. In this new standard, more high level insulation of the building envelope is required, yearly energy requirement for heating must be less than 55 kWh/(m(2).a)(regarded as a low-energy house). The new attempt was carried out in the process of architecture design with an evaluation on energy consumption of the building. The design plan was brought forward and compared. PHPP software from German was applied to calculate energy consumption of the passive residential building. The optimum design planning was discussed and model of passive house suited to China's national conditions were attempted. The compactness, solar air collector and the window-wall ratio have essential influence on the energy consumption of buildings. The annual heat demands for the buildings with the window-wall ratio 0.35 and 0.50 are 48 kWh/(m(2).a) and 46 kWh/(m(2).a), respectively. The yearly auxiliary heat of building with the wall-mounted solar air collectors and the window-wall ratio 0.35 is just 4.8 kWh/(m(2).a).
