低碳建筑的评价指标初探

Preliminary research on the evaluating indexes for low-carbon buildings

提出用"建筑利用中的人均碳排放指标"和"建筑用能过程碳减排效率"对低碳建筑进行评价。指出建筑碳排放实质上是人的碳排放,建筑只是使用者的能耗平台。因此,对建筑碳排放的评价要用强度指标,即建筑使用者人均碳排放指标。而对建筑设备的碳排放评价,是一个投入产出分析过程,即投入隐含碳、间接碳和直接碳,产出"避免碳排放量"的效率。同时计算得出我国太阳能光伏发电的隐含碳排放量。

Proposes using the concepts of ＂per capita carbon emissions index for building usage＂ and ＂the efficiency of carbon mitigation for building usage＂ for assessing how low-carbon a building is.Points out that the carbon emission of a building is essentially from its occupants while the building is only a platform of energy consumption by the users.Therefore,in evaluating carbon emissions from buildings the intensity index-per capita carbon emissions index-should be accepted.And the evaluation of carbon emissions from building service system is an input-output analysis process where involving assessment of the efficiency of inputting the embedded carbon emission,indirect and direct carbon emission,and producing the ＂avoided carbon emissions＂ for buildings.Calculates the embedded life-cycle carbon emission of PV power in China.
