BIM技术在绿色建筑碳排放量计算中的应用研究

Research on the application of bim technology in the calculation of carbon emissions for green buildings

通过建立建筑信息化模型对建筑全生命周期进行碳排放计算,依据《建筑碳排放标准》和《绿色建筑评价标准》,对建筑碳排放计算结果进行体系评估,以确定绿色建筑等级。以苏州市某中学教学楼为例,通过绿色建筑节能系列软件进行BIM技术的实际应用与计算原理的讨论。结果表明,建筑物运行阶段的碳排放量占建筑全生命周期碳排放量的50%以上,减少运行阶段的碳排量对建筑绿色评价等级具有重要意义。从分析计算原理得出,建筑物全生命周期各个阶段的碳排放量相互关联,相互影响,通过降低其他阶段的碳排放量,可以间接降低运行阶段的碳排放量的理念,最大程度开发建筑物的节能潜力。

By establishing a building information model to calculate carbon emissions throughout the entire life cycle of a building,and based on Building Carbon Emission Standards and Green Building Evaluation Standards,the carbon emission calculation results are systematically assessed to determine the green building grade.Taking a middle school teaching building in Suzhou as an example,the paper discusses the practical application and calculation principles of BIM technology through a series of green building energy-saving software.The results show that the carbon emissions during the operation phase of a building account for more than 50%of the total carbon emissions throughout the life cycle,and reducing carbon emissions during the operation phase is of great significance for the green building evaluation grade.From the analysis of the calculation principles,it is concluded that the carbon emissions at each stage of the building's entire life cycle are interrelated and mutually influential.The concept of reducing carbon emissions in other stages to indirectly reduce the carbon emissions during the operation phase is proposed,in order to maximize the energy-saving potential of the building.
