民用建筑怎样实现降低20%能耗的目标
How to achieve the national goal of “the energy use per unit of GDP must be reduced by 20%” in civil buildings
摘要：
根据国家“十一五”规划中单位产值节能20%的战略目标，指出应制定前瞻性的建筑节能目标。认为节能比较的基准应为2005年的建筑能耗实物量。估算出2010年建筑节能量约为1亿t标准煤，为实现这一建筑节能目标，建议针对围护结构传热、系统设备能效、温室气体减排、住宅能耗标识的建立等关键问题采取相应措施。

Abstract：
According to the strategy target in the National 11th FiveYear Plan, proposes that a forwardlooking goal should be set for building energy saving. Considers that the actual quantity of building energy consumption in 2005 be used as the baseline of comparing. Estimates that 100 million tons standard coal equivalent should be saved in civil building sector by 2010. Suggests several options on heat transfer of building envelopes, equipment and system efficiency, mitigation of greenhouse gas emission and energy consumption labelling of residential buildings to achieve the goal.
