摘　　要：随着我国进入快速城市化的历史阶段,很多单体建筑节能设计无法解决的问题,如城市交通能耗的降低、既有建筑的节能改造、城市能源系统的低碳化、城市能流的合理化等,都需要从城市或城区层面统筹协调。将城市能源供应分成三个层次,即城市、社区和终端,又可以分成生产、输配和用户三个环节。同时将城市能源消耗分成生产性能耗和消费性能耗两部分,以及产业、交通、建筑三个领域,分别分析了它们的能耗特点和节能措施,并提出了城市节能的关键性能指标。As China enters the historical period of rapid urbanization,numerous problems that cannot be resolved by single building energy efficiency design,such as energy consumption reduction of urban transport,energy efficient renovation of existing buildings,the city＇s low-carbon energy system,and the rationalization of urban energy flow etc.would require co-ordination at the level of city or community.The urban energy supply can be divided into three levels,namely,urban,community and end user,or into three segments i.e.production,utility distribution and customers.Treats the urban energy consumption as two parts—one for productive purpose and the other for consumptive purpose—and three sectors of industry,transport and buildings.Analyses their characteristics of energy consumption and energy saving measures and proposes the key performance indicators of urban energy efficiency.
