建筑全生命周期碳排放可以全面反映建筑对环境的影响.研究以2005年建造的高层居住建筑全生命周期碳排放计算结果作为基准参数,与两栋低碳建筑的全生命周期碳排放计算结果进行对比分析.结果发现:通过建造、使用和拆解阶段的全面控制,可以将建筑全生命周期碳排放强度较2005年的基准水平大幅下降,并针对性地提出了具体的建筑全生命周期减碳策略.

Carbon emissions throughout the life cycle of buildings can fully reflect the impact of buildings on the environment. In this study, the calculation results of the full life-cycle carbon emissions of high-rise residential buildings constructed in 2005 are taken as the benchmark parameters and compared with the relevant parameters of two low-carbon buildings. The research finds that through the comprehensive control of the construction, use and dismantling phase, the carbon emission intensity of the building's life cycle can be significantly lower than the 2005 baseline, and based on the research results, specific life-cycle carbon reduction strategies for buildings are proposed.
