摘　　要：针对上海地区339栋新建建筑能效测评数据进行研究和分析,包括近10年来上海地区新建建筑节能设计依据变化情况、能效标识等级、外墙和屋面实际保温材料种类、空调设备类型、建筑理论值能耗水平及节能率分布等。研究结果显示:新建建筑的节能设计依据均逐渐完善,已达较稳定状态;公共建筑以一星级和三星级居多,居住建筑以二星级和三星级居多;公共建筑外墙保温采用岩棉板为主,屋面保温主要采用泡沫玻璃板;居住建筑外墙保温主要为无机保温砂浆,屋面则以挤塑聚苯板和泡沫玻璃板为主,实际应用时受政策和新技术影响较大;空调系统方面,公共建筑主要采用集中式空调系统,居住建筑则主要采用VRF系统;能耗强度方面,公共建筑能耗强度均值为75.55 kW·h/(m2·a),能耗分布跨度较广;居住建筑理论测评能耗均值为34.66 kW·h/(m2·a),能耗分布相对集中;测评标识评价指标自2015年开始,逐步由节能率转变为相对节能率,评价体系更加完善。开展本项研究将为进一步推动上海地区建筑能效测评工作提供技术借鉴,也为后续新建建筑的节能设计优化提供一定的参考。The energy efficiency evaluation data of 339 new buildings in Shanghai are analyzed, including the change of energy-saving design basis of new buildings in Shanghai in the last decade, energy efficiency labeling grades, types of actual insulation materials of exterior walls and roofs, types of air conditioning equipment, building theoretical energy consumption level and distribution of energy-saving rate, etc. The research results show that the energy-saving design basis of new buildings is gradually improved, which has reached a relatively stable state. Public buildings are dominated by one star and three stars, while the residential buildings are mostly two stars and three stars. The external wall insulation of public buildings is mainly made of rock wool boards, and foam glass panels are used for roof insulation. The thermal insulation mortar is the main insulation for residential buildings, and the roof is mainly extruded polystyrene board and foam glass plate. Considering the actual application, it will be greatly influenced by real-time policies and new technologies. In terms of air conditioning system, the public buildings mainly adopt centralized air conditioning system, while the residential buildings mainly adopt VRF system. In terms of energy consumption intensity, the average energy consumption intensity of public buildings is 75.55 kW·h/(m2·a), with a wide energy consumption distribution. While the average energy consumption intensity of residential buildings is 34.66 kW·h/(m2·a), with a relatively centralized energy consumption distribution. Take the year 2015 as a critical point, the index of evaluation mark has been determined from the energy-saving rate to the relative energy-saving rate. The evaluation system has been more perfect. Carrying out this research will provide technical reference for furtherly promoting the building energy efficiency evaluation work in Shanghai, and also provide some reference for the following energy-saving design optimization of new buildings.
