摘要
基于建筑全生命周期理论,研究装配式模块化钢结构学校建筑的碳排放计算模型,结合模块化建筑的特点,将其生命周期划分为 7 个阶段,并确定各个阶段碳排放的计算方法,并采用排放系数法,计算各阶段的碳排放指标和年单位建筑面积碳排放量.同时为探讨模块化技术在节能减排上的作用,选取钢筋混凝土和装配式钢结构两种结构的学校建筑进行定量计算并与模块化学校进行对比.研究结果表明:模块化技术能有效降低建筑物化阶段的碳排放量,并在循环再利用上具有独特优势.
Abstract
A carbon emission model was developed to study the modular school buildings based on the theory of life cycle assessment(LCA).According to the characteristics of modular buildings,the whole life cycle of the building was divided into seven stages,and the calculation method of carbon emissions in each stage were determined.Then the carbon emission index and annual carbon emission per unit building area at each stage were determined by emission coefficient method.Meanwhile,the carbon emission of concrete structure and fabricated steel structure school building were calculated to compared with modular structure school building,in order to discuss the impact of modular technology on energy conservation and emission reduction.The results shows modular technology can reduce carbon emissions effectively,and has unique advantages in reusing of buildings.
