中文摘要 | 为研究中国城市住区全寿命周期CO2排放情况,综合考虑住区住宅建筑排放量和绿地吸收量,提出计算方法,并以北京为例选择典型多层住区单元地块进行计算,讨论减排方法和减排潜力。计算结果表明:在现行规范、现有能源结构和技术水平下,案例住区建筑CO2排放量中约3%可由住区绿地吸收。通过推行节能措施和利用可再生能源,可实现减排约50%。而实现住区零排放,则需要从城市整体角度大量依靠郊区森林碳汇资源。; The lifecycle analyses of CO2 emissions in Chinese urban residential communities need methods to predict the CO2 emissions of buildings and the CO2 sequestration in greenspaces.The method given here is applied in a case study with suggestions on how to reduce the emissions.The results show that in a typical Beijing residential community,the CO2 sequestration by current greenspaces only balances around 3% of the building emissions under current regulations and standards.The CO2 emissions may be reduced by 50% by energy efficiency strategies and renewable energy sources;however,the other 50% will have to be neutralized by suburban forests. |
