Abstract：

Based on the survey and calculation, calculates and analyses the cooling energy consumption of air conditioning for the residential buildings in China’s urban areas by simulation induction method (SIM). The results show that level of the average cooling energy consumption of urban residential buildings in China is still lower at present, but the difference of the data among different climate zones is great and the cooling energy consumption is increasing rapidly. The total cooling electric power consumption of residential buildings in these areas in 2005 is about 28.5 billions kWh and the average cooling electric power consumption index per unit floor area is 2.65 kWh／m². The rank order in descending sort for four provinces in the top of cooling energy consumption is Guandong, Zhejiang, Jiangshu and Hubei. The total cooling energy consumption in urban residential buildings of these provinces accounts for about 51.8 percent of that for all provinces. It is important to reduce the cooling energy consumption in the urban areas in Guangdong, Fujian, Chongqing, Zhejiang, Shanghai, Hubei, Jiangshu and Guangxi.
