摘　　要：基于碳中和及零废弃物的可持续发展目标,通过文献综述和理论分析确定建筑循环潜力量化计算方法,提出材料循环数据库与数字建模工具协同的设计流程。以重型木结构建筑瑞典卡斯塔登住宅楼为例,通过BIM-Eco2soft-MS Excel的工作流程获取建筑的材料及构件信息、50年建筑使用期限内资源消耗及环境影响值,并实现建筑循环潜力的定量计算。进而分析了建筑设计决策对于实现负碳排放和废弃物源头减量的重要影响,为重型木结构建筑的材料选择、构件设计和循环潜力优化提供参考。Based on the sustainable development targets of carbon neutralization and zero waste,this paper proposes the methodology for the recycling potential calculation consisting coupling of Material Cycle Database and digital design tools through literature review and theoretical analysis. Through the case of Kajstaden residential building in Sweden, it establishes the BIM-Eco2soft-MS Excel workflow to obtain information on building materials and components, the resource consumption, the environmental impact within a 50-year service life, and the quantitative calculation of recycling potential. It further analyses the important role of architectural design decisions in realizing the negative carbon emissions and waste reduction, and provides a reference for material selection, component design and recycling potential optimization of mass timber buildings.
