本文对我国夏热冬冷地区主要城镇居住建筑能耗调研数据及各地统计数据进行了对比分析。结果表明,2000～2010年,随着经济水平的高速增长,夏热冬冷地区主要城市城镇居住建筑能耗除上海稳定增长外,其余城市均高速增长,2010年的单位建筑面积年用电量基本都达到了30～32 kWh/(m2.a)。另外,调研数据显示,夏热冬冷地区空调和供暖以部分时间和部分空间的间歇式为主,夏季空调用电量为6～7 kWh/(m2.a)、冬季供暖用电量为2～4 kWh/(m2.a),而少数集中空调系统的能耗是平均值的3倍以上。
This paper analyzes the energy consumption of residential buildings in major cities and towns in hot summer and cold winter area in China and the statistical data of different places. The results show that from 2000 to 2010, with the rapid economic growth, the energy consumption of residential buildings in major cities in hot summer and cold winter regions in addition to the steady growth of Shanghai, the other cities are growing rapidly in 2010, the unit area of ?? annual electricity consumption Basically reached 30 ~ 32 kWh / (m2.a). In addition, the survey data show that the air-conditioning and heating in summer hot and cold winter are mainly intermittent with partial and partial space. The electricity consumption in summer is 6 ~ 7 kWh / (m2.a), and that in winter is 2 ~ 4 kWh / (m2.a), while the energy consumption of a few centralized air conditioning systems is more than three times the average.
