摘要
相比于传统现场浇筑方式,模块化建筑物化阶段特有的生产方式在理论上可以有效减少碳排放。模块化建筑物化阶段减排活动复杂,对减排管理提出了新挑战。首先,识别模块化建筑物化阶段碳排影响因素,从项目概况、建材消耗、能源消耗、运输与仓储、施工组织、生态环境6个方面建立评价指标体系;其次,采用模糊层次综合评价法(Fuzzy Analytic Hierarchy Process,FAHP)评价法构建减排效率评价模型;最后,结合模块化项目案例提出节能减排措施。通过案例分析发现,建材消耗对减排效率影响最大,其次为项目概况和施工组织;模块化项目案例在项目概况、施工组织上存在巨大的节能减排优势,在其他方面的节能减排还有待加强。通过模块化建筑物化阶段减排效率评价研究,探索其节能减排潜力,可为模块化建筑节能减排策略提供参考。
As the main direction of the future construction industry,it s particularly important to evaluate the emission reduction efficiency of Modular Integrated Construction(MiC),and the main reason for the difference in carbon emission between MiC and cast-in-place buildings or traditional prefabricated buildings is focused on the materialization stage.Therefore,this paper digs deeper into the carbon emission impact factors in the modularization stage of MiC and establishes an evaluation index system from six aspects:project profile,building materials consumption,energy consumption,transportation and storage,construction organization,and ecological environment.Besides we verify the feasibility and universality of the evaluation indexes in the latter part of the paper.On this basis,the FAHP evaluation method is used to construct an evaluation model of emission reduction efficiency in the modularization phase.Finally,Both the rationality of the evaluation indexes and the feasibility of the efficiency evaluation model are verified by combining the MiC project cases,and energy-saving and emission reduction measures are proposed from four aspects:building materials consumption,project profile,construction organization,and energy consumption.The case analysis shows that the consumption of building materials has the greatest impact on the efficiency of carbon emission,followed by project profile and construction organization,then energy consumption,ecological environment,transportation,and storage;the choice of modular prefabricated materials and the use of green materials are particularly important;the MiC project case has great advantages in energy saving and emission reduction in project profile and construction organization,and energy saving and emission reduction in four aspects:building materials consumption,energy consumption,transportation and storage,and ecological environment still need to be strengthened.Through the evaluation study of emission reduction efficiency in the materialization stage of MiC,we explore its
