建筑建造与运行能耗的对比分析
Comparison between construction and operation energy consumption of buildings
摘要：
从建材含能和运输能耗出发，介绍了建造能耗的简化计算方法，并对目前我国住宅、普通办公建筑、大型办公建筑三类建筑建造能耗进行了案例分析。结果表明，三者的建造能耗平均水平分别约为3 850，5 500，7 300 MJ/m2，分别相当于各自8，13，9 a运行总能耗；钢材、水泥、混凝土、墙材为主要耗能用材。
Abstract：
Based on the research of the energy embodied by building materials and transportation energy consumption, presents a simplified calculation method for construction energy consumption. Analyses a large number of cases, including residential buildings, normal and large-scale office buildings. Finds out that the average level of construction energy consumption of the three buildings are approximately 3 850, 5 500 and 7 300 MJ/m2 separately, and is respectively equal to their total operation consumption of 8, 13 and 9 years. Moreover, the result also shows that steel, cement, concrete and wall materials are main energy consumption materials.
