基于生态足迹法低碳住宅系统构筑的分析

Analysis on Low Carbon House's Construction Based on Ecological Footprint Method

生态足迹分析方法作为一种衡量自然资本可持续利用的生物物理定量评价工具,得到了越来越广泛的关注和应用。一栋建筑从设计、建设到运营、拆毁,需要消耗大量的资源和能源。本文选取2种类型的低碳住宅和对比住宅为研究对象,通过对生态足迹、生物承载力以及生态足迹指数等的计算分析,阐述了建设阶段和运营阶段生态足迹比重的变化以及各项资源所占生态足迹比重的对比,为明确低碳建筑的设计方向提供了参考依据。

As a biophysical quantitative evaluation tool for measuring the sustainability of natural resources,the ecological footprint method has been obtained more and more attention and application.For one building,plenty of resources and energy must be used during the periods of design,construction,operation and demolition.In this paper,two kinds of low carbon houses and a contrast house were selected as the study objects,based on the calculation of ecological footprint,biocapacity and ecological footprint index,the variation of ecological footprint proportion for construction and operation periods were discussed,furthermore,the comparison of ecological footprint proportion of different kinds of resources were carried out.The results were meaningful for improving the low carbon building design.
