在我国双碳目标下,建筑减碳任重道远,碳排放计算成为一个设计显性要素引起建筑师的广泛关注.本文选取本团队在第二届(2018年)、第三届(2022年)中国国际太阳能十项全能竞赛的参赛作品栖居2.0(装配式木结构)、栖居3.0(装配式钢结构)作为研究对象,通过计算其建筑全生命周期碳排放,对比两栋建筑全生命周期碳排放构成的特点,分析两栋建筑的低碳策略及实际效果,从体系优化、材料运用、隐含与运行耦合3个方面提出针对北方寒冷地区的建筑减碳策略.
Under China's dual-carbon targets,there is a long way to go for carbon reduction in buildings.Carbon emission calculation,as an explicit design element,has attracted widespread attention from architects.In this study,the research objects are"Qiju 2.0"(prefabricated wood structure)and"Qiju 3.0"(prefabricated steel structure)from the second(2018)and the third(2022)Solar Decathlon China(SDC)competition.By calculating the carbon emissions of the whole life-cycle of the two buildings,demonstrating the comparative carbon emission characteristics of the two buildings,and analysing the low-carbon strategies and practical effects of the two buildings,useful data and references are provided for carbon reduction in building design.
