摘　　要：我国已处于城镇化的后半程,加上“30目标+60愿景”国际承诺的做出,标志着存量更新和低碳规划将成为我国城市开发建设和转型发展的基本语境。建筑碳排是城市中的重要碳排放源,亦是影响城市更新的主要碳排因素和计算因子,针对当前我国城市更新中建筑碳排计算研究的缺失,以控规单元尺度为研究范围,以建筑碳排预计算为研究对象,综合运用多种定量研究方法与工具平台及图式化语言进行研究分析。在能耗模拟框架下,对三种常用建筑碳排预计算方法进行比选,选取“根据规划用地类型与强度推算建筑能耗”的碳排计算方法。以武汉滨江商务区七期地块为实证地块,根据城市更新规划设计方案,对城市更新后建筑碳排进行预计算及结果分析;并对现状地块的建筑碳排进行计算,对比分析地块更新前后建筑能耗的减排效应并进行原因探析,得出经过低碳城市更新后的建筑碳排降幅可达到约88%,主要原因在于高能耗建筑类型的减少及用地功能与性质的改变。在实证研究的基础上,从三个方面提出控规单元尺度城市更新的低碳规划策略与技术路径,最后对研究的科学价值和现实意义进行讨论,并提出未来研究应继续努力与完善的方向。As China entering the second half of urbanization,the international commitment of“30 targets+60 visions”indicates that urban renewal and low-carbon planning are the basic background of China’s urban construction and development,which means that urban construction and development can only be achieved by stock renewal and low-carbon planning.And urban low-carbon transformational development is the key to stock renewal and achievement of“30 targets+60 visions”.Since 2016,research on carbon emission has developed rapidly both domestically and internationally,but the research spatial scope mainly focuses on administrative units as the main research space in order to get research data and information conveniently.There is almost no research on the pre-calculation of building carbon emission of stock urban renewal plot at the scale of regulatory detailed plan.Reviewing existing research,most of it has focused on the impact mechanism of carbon emission,the constraint mechanism of carbon emission,and the methods,strategies,planning ideas for low-carbon emission reduction.And most existing studies have used both qualitative and quantitative research methods,it is undeniable that there is no relevant research on the pre-calculation of building carbon emission for urban renewal planning and design schemes at the scale of regulatory units.Response to the lack of research on building carbon emission calculation in urban renewal at the scale of regulatory unit in China,this study focuses on the scale of regulatory unit as the research scope and the pre-calculation of building carbon emission as the main research object.Multiple quantitative research methods,tool platforms,and graphical languages are comprehensively used for research and analysis,Energy Plus is the popular and commonly used energy consumption simulation calculation platform and software.Under the framework of energy consumption simulation,three commonly used building carbon emission pre-calculation methods are compared,finally the carbon emission calcu
