摘　　要：以天津地区居住建筑为研究对象,通过对用户供暖耗热量的采集和统计,了解了居住建筑在运行过程中的供暖能耗现状,分析了运行能耗过高的原因。结果表明,合理的室内温度控制措施可实现运行节能22%。通过对中德两国居住建筑设计热需求和供暖运行能耗的分析与对比,发现中国居住建筑三步节能标准与德国EnEv2002和EnEv2009节能标准相比,围护结构节能潜力分别可达17%和35%。在同等气候条件下,满足三步节能标准的中国居住建筑供暖运行比德国满足EnEv2002标准的建筑多消耗73.2%的能源。Taking the residential buildings in Tianjin as research objects, based on the actual heating energy consumption data, investigates the present situation of heating energy consumption in actual operation and analyses the related reasons resulting in high heating energy consumption. The result shows that heating energy consumption can be saved by 22% if reasonable indoor temperature control measures are adopted. Compares Chinese and German residential building energy saving standards in two aspects, namely design heat demand and actual heating energy consumption, and finds that there are 17% and 35% of energy saving potential from building envelope compared Chinese third-step energy efficiency standard with German EnEv＇ 2002 and EnEv＇ 2009, respectively. The actual operation heating energy consumption of the residential building satisfied Chinese third-step energy efficiency standard is 73.2% higher than the one satisfied German EnEv＇ 2002.
