摘要:本文基于实际工程,对临时建筑碳排放进行计算和分析。首先将临时建筑现场分为办公区和生活区,统计两区面积及不同时段人员数量;其次采用碳排放因子法建立碳排放核算模型并计算两区碳排放量;最后用相关性分析和线性回归法分析影响因素与碳排放之间的关系。结果表明,用电碳排放在临建房屋总碳排放中占主导地位,其中办公区碳排放量为生活区碳排放量的1.5倍,是临时建筑低碳管理的重点。关键词:临时建筑;施工现场;建筑碳排放;相关性分析Abstract:This paper calculates and analyzes the carbon emissions of temporary buildings based on actual projects. Firstly,the temporary construction site was divided into office and living areas,and the area of the two areas and the number of personnel at different times were counted. Secondly,the carbon emission factor method was used to establish a carbon emission model and calculate the carbon emissions of the two regions. Finally,correlation analysis and linear regression analysis were used to analyze the relationship between influencing factors and carbon emissions. The results showed that the carbon emission of electricity consumption was dominant in the total carbon emission of temporary buildings,and the carbon emission of office area was 1.5 times that of living area,which is the focus of low-carbon management of temporary buildings.Keywords:temporary buildings;construction site;building carbon emissions;correlation analysis参考文献[1] 潘毅群,梁育民,朱明亚.碳中和目标背景下的建筑碳排放计算模型研究综述[J].暖通空调,2021(7):37-48.[2] 李兵,李云霞,吴斌,等.建筑施工碳排放测算模型研究[J].土木建筑工程信息技术,2011(2):5-10.[3] G.
