城市住区低碳评价指标体系建构

从城市住区的低碳评价的目标单一性、评价量化性等特点出发,对城市住区低碳评价体系的目标进行设计.确定规划设计阶段、施工(竣工验收)阶段和运行使用阶段作为进行城市住区评价的三个主要时期,同时选取住区生命周期、各阶段、各主要能源系统共计10个低碳评价对象,并设定相应的低碳指数作为评价指标.在对各个评价指标的分析中,确定各个评价对象碳排放的模拟预测值或实际值的计算方法,同时明确相应基准排放值的确定方法,完成相应低碳指标的计算.最后,以构建的基准值作为分界点,将相关评价对象的低碳评价分级划分成七个梯度.

Study on Low Carbon Evaluation Index System of Urban Residential District

Based on the characteristics of single goal, quantization of low-carbon evaluation of urban residential district, goals of low carbon evaluation system was designed. The planning and design stage, construction(final acceptance)stage and the operational stage are selected as three major evaluate stages of urban residential district evaluation system. Meanwhile, select life cycle, each stage, the main energy system etc. are selected as 10 evaluate object, and set the appropriate low-carbon index is set for them. The method of simulation value and actual value of carbon emissions of each object is built, and each low carbon index is calculated. Based on the cut-off point established, the low carbon evaluation is divided to seven gradients.
