摘要
保温材料被用于建筑物的围护结构,可以有效减少建筑物与外界环境的热交换行为,从而减少热量损失节约能耗,是推动我国建筑业节能环保发展的重要研究方向。为选取最具环境正效益的保温材料,采用生命周期评价(LCA)方法,在保证传热系数相同的条件下,选取5种典型外墙外保温墙体,运用eBalance软件对其所产生的能源与资源消耗以及环境排放进行计算,并对5种墙体进行特征化与归一化处理,计算其节能减排指标。结果表明:相同传热系数下泡沫混凝土保温墙体对环境的影响最小,岩棉板蒸压加气混凝土砌块墙体对环境影响最大。对不同类型的保温墙体进行环境影响分析,为今后建筑保温墙体材料的选择提供一定的参考。
Thermal materials are used in the building envelope can effectively reduce the heat exchange behavior between the building and the external environment,so as to reduce the heat loss and save energy consumption.It is an important research direction to promote the development of energy conservation and environmental protection in China's construction industry.In order to select the most environmentally beneficial insulation materials,a life cycle assessment method was adopted.Under the condition of given the same heat transfer coefficient,five typical external wall insulation walls were selected,and the energy and resource consumption and environmental emissions generated by the five different thermal insulation walls are calculated by ebalance software,and the five kinds of walls are characterized and normalized,Calculate its energy conservation and emission reduction indicators.The results show that the foam concrete insulation wall has the least impact on the environment under the same heat transfer coefficient,and the rock wool board autoclaved aerated concrete block wall has the greatest impact on the environment.The environmental impact analysis of different types of thermal insulation walls provides a reference for the selection of building thermal insulation wall materials in the future.
