低碳建筑的评价指标初探
Preliminary research on the evaluating indexes for low-carbon buildings
摘要：
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。
Abstract：
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.
