面向大型公共建筑的碳排放综合评估装置研究

Research on carbon emission comprehensive assessment device for large public buildings

建筑耗能是我国能源消耗的三大“耗能大户”之一,大型公共建筑的耗电量占建筑总能耗的22%,其对应的碳排放量也居高不下。本项目研究分析大型公共建筑的用能模型,涵盖能源种类、分项用能等多个维度,综合考虑交通、碳汇等碳排放来源,结合通用的碳排放因子计算方法,确定大型公共建筑的碳排放综合评估算法。最后,实际研制碳排放综合评估装置,并在实际建筑中应用。结果表明,碳排放综合评估装置能够方便的收集基础数据,并将碳排放结果以接口和交互方式对外输出,帮助客户更好地评估建筑的碳排放情况。

Building energy consumption is one of the three“big energy consumers”in China’s energy consumption.The power consumption of large public buildings accounts for 22%of the total building energy consumption,and its corresponding carbon emissions are also high.This project studies and analyzes the energy consumption model of large public buildings,covering multiple dimensions such as energy types and sub item energy consumption,comprehensively considers the carbon emission sources such as transportation and carbon sink,and determines the comprehensive carbon emission assessment algorithm of large public buildings in combination with the general carbon emission factor calculation method.Finally,a comprehensive carbon emission assessment device is developed and applied in actual buildings.The results show that the comprehensive carbon emission assessment device can easily collect basic data and output the carbon emission results in an interface and interactive manner,helping customers better assess the carbon emissions of buildings.
