基于全生命周期分析的北方农村住宅被动式集热墙体的环境影响分析

该文采用全生命周期的分析方法,比较在采用相同保温措施的情况下,与普通保温墙体相比,三种形式的被动集热墙在全寿命周期的范围内的采暖能源消耗、温室气体及固体废弃物排放情况.通过比较分析可以看出,直接受益式和附加阳光间式集热墙体在能源消耗、温室气体和固体废弃物的排放量上均小于对比房,在环境影响上具有明显的优越性;集热蓄热墙的...

Environmental Impact Analysis of Passive Solar Collecting Walls of Northern Rural House Based on the Whole Life Cycle Analysis Method

Based on the whole life cycle analysis method,the paper intends to study the passive solar collecting wall＇s three modes in heating energy consumption and the emissions of greenhouse gas and solid waste,in contrast to ordinary insulating walls.The analysis shows,first,in terms of energy consumption and the emissions of greenhouse gas and solid waste,both the directly beneficial mode and additional sunshine-room mode are smaller and have obvious superiority in environmental impacts over their equivalent;second,in terms of energy consumption and the emissions of greenhouse gas,the collecting and storing heat wall is smaller than its equivalent,but in terms of solid waste discharge,it is a bit higher.If the utilization of the solid waste can be improved,its environmental impacts will be largely reduced.
