随着农村生活水平的提高,农民对居住环境有了更高的要求,随之而来的是建筑面积和能耗的增加。外墙热工性能直接影响着建筑能耗和室内热环境,如何选择外墙构造成为了亟待解决的问题。本文以严寒地区的东北农宅外墙为研究对象,将全生命周期理论与生态足迹理论结合,定量分析不同构造外墙对环境的影响,从而优选出节能环保的外墙构造。
With the improvement of living standards in rural areas, farmers have higher requirements for living environment, followed by an increase in construction area and energy consumption. The thermal performance of the external wall directly affects the building energy consumption and indoor thermal environment, how to choose the external wall structure has become an urgent problem to be solved. In this paper, the exterior wall of northeast farmhouse in the cold area is taken as the research object, the whole life cycle theory and the ecological footprint theory are combined to quantitatively analyze the influence of different exterior facades on the environment, so as to optimize the external wall structure of energy saving and environmental protection.
