摘　　要：对获得建筑能效标识的近400个项目数据进行了统计分析,包括能效标识等级、气候区域、建筑能效理论值能耗强度与节能率分布等。结果表明,公共建筑和居住建筑以一星级为主;受政策和技术因素影响,夏热冬冷地区建筑能效标识项目较多,但是高星级项目数量较少;居住建筑能耗强度随节能率升高而减少,高星级公共建筑的能耗强度随节能率升高呈增加趋势。研究了可再生能源利用技术和节能技术的特点和应用情况,其中公共建筑单位面积能耗强度均值为86.8 k W·h/(m^2·a),主要应用了热泵技术和自然通风采光及楼宇自控技术;居住建筑单位面积能耗强度均值为33.5 k W·h/(m^2·a),主要应用了太阳能光热和自然通风采光技术。Based on the data of nearly 400 projects of building energy efficiency labeling, statistics and analysis were conducted of the distribution of labeling level, climate region, theoretical energy consumption intensity and energy-saving rate, etc. The results show that the labeling level of public buildings and residential buildings are one-star ones and affected by policies and technologies, there are more projects in hot summer and cold winter areas than high-star projects. The higher the building energy consumption intensity, the lower the energy efficient rate in residential buildings but they are in positive proportion to each other in high-star public buildings. The features and application of renewable energy technology and energy-saving technology were also studied, and the average energy consumption intensity per unit building area of public buildings was 86.8 kW·h/（m2 · a） and the residential buildings 33.5 kW·h/（m2· a）. Heat pump technology, natural ventilation and lighting and building automation technology were mainly applied in public buildings, and solar thermal technology and natural ventilation and lighting in residential buildings.
