摘要选取代表性现代木结构建筑并对其全生命周期碳足迹开展了研究,提出将负碳建材碳排放拆分为生产过程碳排放和生物固碳值的方法,定量计算了结构生命周期各阶段的碳排放量,对木材在不同生命周期间的再利用情况进行了分析.结合传统材料建筑全生命周期碳排放,对比分析了现代木结构建筑与传统材料建筑全生命周期碳排放特点.研究结果显示,本研究中的木结构建筑全生命周期碳排放为1.69×10⁷kgCO₂e,其中物化阶段占比15.56%、使用阶段占比84.34%、拆除阶段占比0.10%;其物化阶段的碳排放比传统钢筋混凝土结构和钢结构均有所降低.

Abstract：This paper researched the building life cycle carbon footprint based on a representative modern timber building in China, and a method of splitting the carbon emission of negative carbon building materials into the carbon emission of the production process and the biological carbon sequestration value was proposed. The results showed that the carbon emissions of the life cycle of the modern timber office building were 1.69×10⁷kgCO₂e, in which the product stage accounted for 15.56%, the use stage accounted for 84.34%, and the end-of-life stage accounted for 0.10%. The carbon emission in the product stage of timber building was lower than that of traditional reinforced concrete or steel buildings.

Key words： timber buildings carbon emission life cycle assessment negative carbon building materials
