全生命周期建筑碳排放计算软件对比与结果分析
首发时间:2024-03-13
摘要:建筑领域的碳排放在全球范围内引起注意,各国相继开发了建筑碳排放计算工具,用户选择不同的软件可能会得到不同的结果。本文旨在通过分析国内外使用最广的五款软件,对案例的计算结果进行分析,找出结果差异原因。本研究对比分析了东禾、PKPM-CES、斯维尔CEEB、One Click LCA和Athena这五款软件,基于案例数据计算建筑碳排放。比较从摇篮到坟墓的建筑全生命周期碳排放结果的差异,并且根据软件最大值/最小相对偏差进行比较。经过分析总结出四个方面的原因:1)软件输入参数;2)软件所应用的数据库3)软件计算规则;4)软件输出结果。为了建立更规范、更具有可靠性的建筑生命周期碳排放计算体系,未来仍需要建立更标准化的计算规范。

Comparison of the Results of the Whole Life Cycle Building Carbon Emission Calculation Software
Abstract:Carbon emissions in the building sector have attracted attention around the world, and countries have developed tools to calculate carbon emissions from buildings, and users may get different results by choosing different software. The purpose of this paper is to analyze the calculation results of the case by analyzing the five most widely used software at home and abroad, and find out the reasons for the difference in the results. In this study, we compared and analyzed five software, namely Donghe, PKPM-CES, Swell CEEB, One Click LCA and Athena, to calculate building carbon emissions based on case data. Compare differences in the carbon emissions results of the whole life cycle of a building from cradle to grave, and compare them based on the software maximum/minimum relative deviation. After analysis, four reasons are summarized: 1) software input parameters; 2) the database applied by the software 3) the software calculation rules; 4) The software outputs the result. In order to establish a more standardized and reliable building life cycle carbon emission calculation system, it is still necessary to establish more standardized calculation specifications in the future.
