摘要
以甘肃某图书馆为例,采用Energyplus软件模拟节能率65％建筑、节能率72％建筑、零能耗建筑的建筑能耗(耗电量),对比3种节能建筑全生命周期碳排放量.节能率65％建筑的建筑能耗最高,节能率72％建筑的建筑能耗居中,零能耗建筑的建筑能耗最低.在建筑全生命周期碳排放量中,节能率65％建筑、节能率72％建筑运行阶段碳排放量占比最大,零能耗建筑通过利用可再生能源(光伏发电与风力发电)实现了建筑运行阶段零碳排放.零能耗建筑全生命周期碳排放量最低,仅为节能率65％建筑、节能率72％建筑的9.89％、10.69％,碳排放主要出现在建筑材料生产阶段、建筑建造和拆除阶段.
Abstract
Taking a library in Gansu Province as an example,the energy consumption(electricity consumption)of buildings with energy-saving rate of 65％and 72％and zero-energy consumption was simu-lated by Energyplus software,and the carbon emissions throughout the whole lifecycle of three energy-saving buildings were compared.Buildings with energy effi-ciency rate of 65％have the highest building energy consumption,buildings with energy efficiency rate of 72％have the moderate building energy consumption,and buildings with zero-energy consumption have the lowest building energy consumption.Among the carbon emissions throughout the whole lifecycle of buildings,buildings with energy efficiency rate of 65％and 72％have the highest proportion of carbon emissions during their operation,and buildings with zero-energy con-sumption achieve zero carbon emissions during their operation by utilizing renewable energy(photovoltaic power generation and wind power generation).Build-ings with zero-energy consumption have the lowest car-bon emissions throughout their whole lifecycle,account-ing for only 9.89％and 10.69％of buildings with en-ergy efficiency rate of 65％and 72％,respectively.Carbon emissions mainly occur in the production stage of building materials,construction and demolition sta-ges of buildings.
