本文考察了一个面积为8053 mm²的图书馆如何通过建立全生命周期碳排放评估框架，并定量分析材料生产、运输、施工和运营阶段的碳排放及经济环境效益，来满足三星级绿色建筑认证标准。研究采用广联达性能分析模型，结合国家标准GB/T 51366-2019计算碳排放。通过替换低碳材料、本地采购、预制施工和整合可再生能源等协同优化措施，项目总碳排放减少了68040 kg CO₂-eq，降幅达30.3%，碳强度为19.4 kg CO₂-eq/m²。此外，重要发现可能表明绿色建材应用率达到73%，满足三星级标准。然而，结果可能显示优化后隐含碳有所下降，运营碳成为主要排放源。因此，证据可能表明增量投资回收期仅为4.7年，碳交易收益显著。鉴于这些发现，研究可能表明这些关键实证结果为公共建筑低碳改造提供了一条可复制的路径，也为双碳目标下的相关设计和决策提供了重要证据。

This article examines how an 8053 mm 2 library can meet three-star green building certification standards by establishing a life-cycle carbon emission assessment framework and quantitatively analyzing carbon emissions and economic-environmental benefits during material production, transportation, construction, and operation. The study adopts the Guanglada performance analysis model, combined with the national standard GB/T 51366-2019 to calculate carbon emissions. Through collaborative optimization measures such as replacing low-carbon materials, local procurement, prefabricated construction, and integrating renewable energy, the total carbon emissions of the project were reduced by 68040 kg CO 2 -eq, a decrease of 30.3%, with a carbon intensity of 19.4 kg CO 2 -eq/m 2 . Moreover, the significant findings may suggest that the application rate of green building materials reached 73%, meeting three-star standards. However, results might indicate embodied carbon decreased after optimization, with operational carbon becoming the main emission source. Thus, evidence may show the incremental investment payback period is only 4.7 years, with carbon trading income notable. In light of these findings, the study could indicate that these key empirical results provide a replicable path for the low-carbon renovation of public buildings, also offering important evidence for relevant design and decision-making under the dual-carbon goals.
