对建筑楼宇碳排放量计算模型的探索

对建筑楼宇碳排放量的计算模型进行研究，将有助于评估建筑楼宇整个生命周期对环境的影响。本文对建筑的整个生命周期中各个阶段的二氧化碳排放量进行了探索，通过对建筑物材料及所耗能源数据进行收集与分析，获得不同建筑材料及能源碳排放系数。在前人研究的基础上，建立建筑物碳排放量的计算模型。通过案例分析，得到建筑使用和维护阶段中的碳排放量占到全生命周期的比例最大的结论。

Exploration of Computation Model of Buildings Carbon Dioxide Emissions

Research of computation model of buildings carbon dioxide emissions will contribute to assess the effect of life cycle on environment. This paper explored buildings carbon dioxide emissions across the life cycle, by collecting and analyzing data of building material and power source consumed, carbon emissions factors of different building material and power source. On the basis of previous frameworks, computation model of buildings carbon dioxide emissions could be built. By analyzing case, use-phase emissions and maintenance phase emissions took the largest proportion.
