摘　　要：介绍了我国建筑节能和国外的差距,阐述了嵌入式能量(Embodied Energy)和建筑能量密度(Building Energy Intensity)的特点,说明了亚热带地区的气候与热湿负荷特点,对建筑材料和建筑过程中的能源消耗问题也做出了论述.建筑能耗包括建造过程和使用过程中的总能耗,不能只注重建筑节能的初次投资,或只对运行成本进行节能考虑,要使整个建筑寿命期内嵌入的建筑能量最小,才能有利于建筑节能.The presentation about the gap of building energy saving between China and other countries is illuminated,and the features of embodied energy and building energy intensity are also narrated. Moreover, the introduction is present about the features of subtropical climates, thermal-humidity load and the energy consumption of building materials and construction process. The building total energy consumption involves construction and operation energy,so it can＇t be done only to consider building original investment or operation cost. On the contrary, it convicts that it is helpful to building energy saving to minimize energy intensity embodied in building lifetime.

关 键 词：亚热带 建筑能源效率 嵌入式能量 能量密度 节能
