摘要
首先由建筑含能的概念出发,从建筑构件的角度分析了建筑含能的构成、计算方法以及影响因素,简要探讨了减少建筑台能的可能途径;其次分别以一座钢筋混凝土建筑与一座木结构建筑为例,基于LCA(生命周期评价)的计算结果分析了它们的含能,并将其与各自运行能耗进行了比较。通过分析认为控制建筑含能是建筑节能设计的有效途径之一。
From the concept of embodied energy, this article analyzes its compositions from the perspective of building elements, its calculation methods, and the impact factors. It then briefly discusses possible ways to reduce building embodied energy. It thereafter taking one reinforced concrete building and one timber building as examples, analyzes their embodied energy based on the results of Life Cycle Assessment （LCA） calculation, and compares them with their own operational energy consumption. Finally the article states that it will be one of the effective ways for building energy saving to control building embodied energy.
