基于LCA的内蒙古地区蒙古包建筑碳排放研究

Research of carbon emissions of yurt base on LCA in inner Mongolia Region

本研究以内蒙古自治区呼和浩特市为例,以全生命周期(Life Cycle Assessment)的基本理论为基础,建立适合蒙古包类建筑的碳排放数学模型,利用EnergyPlus能耗模拟软件对不同规格蒙古包类建筑进行使用阶段的能耗模拟,通过对蒙古包类建筑全生命周期碳排放分析,得出蒙古包类建筑在使用阶段的碳排放所占比例达到86%以上;施工阶段、拆除阶段、生产阶段碳排放量各占的比例在7%、4%、2%左右;回收、处理阶段碳排放量所占的比例较小,在整个生命周期内所占的比例几乎为零。蒙古包类建筑在全生命周期内的单位建筑年总碳排放量与建筑使用阶段的单位建筑年总碳排放量接近,其在建筑使用年限达到10年之后趋于稳定。

Based on the basic theory of life cycle assessment,this study establishes carbon emission mathematical model suitable for yurts.The EnergyPlus energy consumption simulation software was used to simulate the energy consumption of different specifications of yurt,and the life cycle assessment that carbon emission of yurts was studied.The proportion of carbon emissions in the use phase of the yurts is more than 86%,and the proportion of carbon emissions in the stage of erection,the stage of demolition and the stage of manufacturing is 7%,4% and 2% respectively.stage of demolition and recycling of carbon emissions in the life cycle assessment is almost zero;The total annual carbon emissions per unit of yurt of the different specifications will stabilize as the service life reaches 10 years.And the unit of construction that use phase of the building annual carbon emissions per unit building tends to be close.Through the analysis of the life cycle assessment carbon emissions of the yurts building,it is possible to make people understand the carbon emissions consumed by each stage of the yurts architecture,and the yurt is better inherited.
