摘　　要：保温结构一体化系统凭借其热工性能、与建筑同寿命等优势,可使建筑在一定程度上减少碳排放。本研究结合生命周期评价理论,选定保温结构一体化产物——增强复合岩棉条板保温系统为研究对象,以1 m2为单位进行了生产阶段的碳排放计算,并以西安市某住宅为例进行了与岩棉薄抹灰外保温系统的建筑生命周期碳排放核算与对比分析。结果表明,采用保温结构一体化系统的建筑可减少约1.61%,即30.5 kgCO_(2)e/m^(2)的生命周期碳排放,同时可避免由于保温系统再次生产运输和施工所造成的人力物力的大量浪费,为建筑领域绿色发展做出显著贡献。The integrated system of thermal insulation and building structure can reduce the carbon emission of the building to a certain extent through its advantages of thermal performance and the same service life with the building.Based on the life cycle assessment theory,this study selected the product of thermal insulation and building structure integrated system-reinforced composite rock wool board as the research object,and calculated carbon emissions during the production phase with 1 m'as the unit.With a residential building in Xi'an as the research object,a life cycle carbon emission calculation and comparative analysis of buildings with an external thermal insulation composite system based on rock wool were made.The results show that the life cycle carbon emission of buildings with an integrated system of thermal insulation and building structure can be reduced by 1.61%,30.5 kgCO_(2)e/m^(2),and the waste of human and material resources caused by the re-production,transportation,and construction of thermal insulation system can be avoided,making a significant contribution to the green development of the building field.
