基于全生命周期的建筑节能研究

Building Energy-saving Research Based on Life Cycle

目前建筑节能的主要关注点是建筑使用阶段运行能耗的节能,而建筑能耗却贯穿于建筑的各个阶段,因此应从生命周期的角度对建筑节能进行研究,这样可以对建材准备、建造、使用等建筑的各个阶段的能耗进行控制,从而达到建筑全生命周期能耗最低,实现真正的节能。首先运用生命周期理论构建出建筑全生命周期能耗的计算模型,在此基础上对我国建筑全生命周期能耗现状进行了分析,最后提出了各个阶段的节能措施。

Currently,the studies of energy-saving are still focused on the operational energy consumption,however,building energy consumption exists throughout the entire life cycle.So the building energy-saving should be studied from the view of life cycle,which can control the energy consumption of entire process such as materials preparation and construction process,so as to achieve the minimum energy consumption for the life cycle and true energy saving.The life cycle theory is applied to construct the calculation model of building life cycle energy consumption.Then the present situation of our country energy consumption is analyzed,and finally proposing some energy-saving measures of each process.
