Carbon Emission Assessment and Mitigation Practices in Building Demolition During Urban Renewal:A Case Study of an Old Residential Community in Nanjing
摘要
Abstract
As the first stage of urban renewal,the demolition of existing buildings creates new space for urban development.Current studies on carbon emissions in the demolition stage primarily focuses on waste disposal processes,while limited attention paid to the demolition process itself.This paper conducts a carbon emission assessment of the manual demolition of an old residential community in Nanjing.The results show that the carbon emissions per unit area during building demolition,waste transportation,and waste recycling are 2.57 kg/m2,4.44 kg/m2,and-13.95 kg/m2(a negative emission due to recycling benefits),respectively.Compared with mechanical demolition,manual demolition achieves a carbon reduction of 15.81 kg/m2 but requires six times more labor days.Furthermore,this study proposes that electrification of construction/transportation equipment,enhanced worker training,and establishment of a construction waste recycling platform could reduce carbon emissions in the demolition phase by about 27%.关键词
