轻型木结构全生命周期碳排放分析及影响因素研究

RESEARCH ON ANALYSIS AND AFFECTING FACTOR OF CARBON EMISSION IN THE WHOLE LIFE-CYCLE OF LIGHT WOOD STRUCTURE BUILDING

木结构建筑由于在建材原料方面的减碳优势得以被重视。本研究基于全生命周期分析法,结合国家碳排放标准,聚焦轻型木结构建筑,测算其全生命周期各阶段碳排放,并比较同等体量的混凝土结构和轻钢结构建筑。结果表明,轻型木结构建筑在建材生产、建材运输、运行、建造拆除阶段碳排放都远低于混凝土结构和轻钢结构建筑,表现出明显的减碳优势。

Wood structure building is taken into account due to its carbon reduction advantages in building materials.In this study,the carbon emissions of the focused light wood structure buildings at each stage of the whole life-cycle are calculated and the concrete structure and light steel structure buildings of the same volume are compared based on the whole life-cycle analysis method and combined with the national carbon emission standards.The results of the study show that the carbon emissions of light wood structure buildings are much lower than those of concrete structure and light steel structure buildings in the stages of production and transportation of building materials as well as construction operation and demolition of buildings,showing obvious carbon reduction advantages.
