建筑材料全寿命期CO2 排放量计算方法

建筑材料CO2 减排是我国整体CO2 减量计划的重要方面，建筑材料CO2 排放量的计算是发展低碳建材、推进建筑节能减排的前提和基础，为此需要确立建筑材料CO2 排放量的计算方法。通过CO2 排放活动分析，从全寿命期和CO2 排放源角度，确定了建筑材料CO2 排放构成；并对六种建筑材料CO2 排放量的计算方法进行了比较分析，选择碳排放系数法作为计算我国建筑材料CO2 排放量的方法；构建了建筑材料全寿命期CO2 排放三阶段计算模型，并提出了建筑材料生产、运输以及处置阶段CO2 排放因子的确定方法。应用实例显示，该方法可较方便地测算出建筑材料全寿命期CO2 排放量。

Life-cycle CO2 Emission Calculation Method of Building Materials

CO2 emission reduction of building materials is the important aspect of CO2 reduction plan in china. The CO2 emission calculation of building materials is the foundation of low carbon materials and energy conservation. It is necessary to establish CO2 emission calculation method of building materials. In this paper, CO2 emissions activities of building materials are analyzed. The composition of CO2 emissions of building materials is determined from life-cycle and sources of CO2 emissions. On the basis of contrast and analysis of the different six methods，the Carbon Emission Coefficient Method was chosen as the CO2 emission calculation method of building materials. The life-cycle CO2 emission calculation model of building materials is built from three stages，and the determinant emission factors are proposed，including the stages of production，transportation and disposal. Case study shows that the method proposed in this paper is more convenient to measure the life-cycle emissions of building materials.
