我国目前一些城市确立和实施一定规模的“平改坡”项目,将使建筑行业中的改造业形成新的发展契机。但是只有设计、施工配套和政策综合作用,才能使其健康发展。相信我国建筑改造业的发展将是迅速的。 屯溪区、徽州区沥青瓦(厂家授权) 以浙江安吉生态屋中的夯土住宅为例,从全寿命周期角度分析其在材料选择、施工方式、构造做法、拆除方式等方面的低碳技术,测算其全寿命周期CO2排放量。结果发现,夯土住宅单位建筑面积年CO2排放量为17.37kg/m2•a,远低于普通砖混结构住宅,在建材生产、建材准备、建筑施工阶段尤为明显。 屯溪区、徽州区沥青瓦(厂家授权) AAnalysisonLow-CarbonTechnologyandCO2EmissionofRammedEarthBuilding:TheCaseofEco-HouseinAnji DUShuting,MAJinzhu(SchoolofCivilEngineering,XuchangUniversity,XuchangHenanChina)Abstracts:Takingrammedearthresidenceof 屯溪区、徽州区沥青瓦(厂家授权) ZhejiangAnjiecoouseprojectasanexample,thelowcarbontechnologyusedinitsmaterialselection,constructionmethods,palisadestructurepractice,demolitionmethodswasanalyzedanditsCO2emissionsinthewholelifecyclewerecalculated.Itwasfoundthat,annualCO2emissionsperareaoftherammedearthresidenceis17.37kg/m2•a,whicharemuchlowerthanthoseofcommonbrick-concretehouse, 屯溪区、徽州区沥青瓦(厂家授权) especiallyinthephaseofbuildingmaterialproductionandconstruction.Thelowcarbontechnologiesinbuildingmaterialsselection,constructionanddemolitionoframmedearthresidencecanbereferencedwhendesigningandbuildingthenewruralhousing.Keywords:rammedearthbuilding;low-carbontechnology;CO2emission;rammedearthresidence
