中文摘要：本文基于BIM(building information modeling)技术获取工程量清单,通过系统功能、数据库及计算过程等设计,并采用Javascript语言开发了一种可视化、易操作的装配式建筑物化阶段碳排放测算系统,可实现建材生产、建材运输、构件生产、构件运输、现场施工安装和现场施工管理等6个部分碳排放的快速计算。以绍兴市某装配式混凝土建筑为例,开展了物化阶段碳排放测算应用研究。结果表明:碳排放测算系统的计算结果与基于传统工程量清单的碳排放测算结果接近,计算结果可靠;建筑材料生产是装配式混凝土建筑物化阶段碳排放的主要来源,占比达到88.13%,是实现建筑业碳减排的关键部分;装配式混凝土建筑物化阶段中装配工艺的碳排放明显低于现浇工艺,其中构件生产及现场安装的碳排放占比仅为现场施工在现浇工艺中碳排放占比的0.56倍,装配工艺在降低碳排放上具有明显优势。研究结果将为快速、准确评价建筑物化阶段的碳排放,以实现碳排放事前控制提供一定的技术支持。

外文摘要：Based on the BIM(building information modeling)technology to obtain the bill of quantities,a visual and easy-to-operate carbon emission calculation system for the materialization stage of prefabricated building was developed by using Javascript language through the design of system function,database and calculation process,which can complete the rapid calculation of carbon emissions in six parts,including production and transportation of building materials,production and transportation of prefabricated units,on-site construction and installation and on-site construction management.Taking a prefabricated concrete building in Shaoxing as an example,the application research of the designed carbon emission calculation system in the materialization stage was carried out.The results show that the calculation results of the carbon emission calculation system are close to those based on the traditional bill of quantities,indicating the calculation results are reliable.The production of building materials such as steel,concrete and cement is the main source of carbon emissions in the materialization stage of prefabricated concrete,which accounts for 88.13%.Therefore,the reduction of carbon emissions from construction material production is a key part of achieving carbon emission reduction in construction industry. The carbon emission of the prefabricated assembly process is significantly lower than that of the cast-in-placeprocess in the materialization stage of prefabricated concrete building. The carbon emission of prefabricated units productionand on-site installation is only 0. 56 times of that of on-site construction in the cast-in-place process. The assembly processshows obvious advantages in reducing carbon emissions. The research results will provide certain technical supports for therapid and accurate evaluation of carbon emissions in the materialization stage of building, so as to achieve carbon emissioncontrol in advance.
