摘　　要：随着城市化进程加快,人口密度提高,建筑高度也在不断增长。建筑加压调蓄系统是高层建筑运行过程中不可或缺的组成部分,近年来各地区逐步推动水务企业接管建筑加压调蓄系统,但目前对建筑加压调蓄系统的碳排放核算仍缺少统一的方法。以全生命周期评价为理论基础,采用排放因子法作为计算方法,构建建筑加压调蓄系统的碳排放核算模型并选取上海市某建筑进行案例分析,最后提出了系统碳减排策略。案例分析结果表明运行维护阶段碳排放占比最大,约为62.5%,进一步说明优化水泵效率对系统碳减排的重要性,为后续的理论研究奠定了基础。With the acceleration of urbanization and the increase in population density,the height of buildings is also constantly increasing.The pressurized and storage system is an indispensable component during the operation of high-rise buildings.In recent years,various regions have gradually promoted water companies to take over pressurized storage systems,but there is still a lack of unified methods for calculating carbon emissions from pressurized storage systems.This study is based on the theory of Life Cycle Assessment and uses the emission factor method to construct a carbon emission accounting model for pressurized storage systems.A building in Shanghai is selected for the case study,and carbon emission reduction strategies are proposed.The final results indicate that the carbon emissions during the operation and maintenance phase account for the largest proportion,approximately 62.5%.This result further demonstrates the importance of optimizing water pump efficiency for reducing carbon emissions in the system,laying the foundation for subsequent theoretical research。
