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 indispen-sable 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 con-struct 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 re-sults 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 opti-mizing water pump efficiency for reducing carbon emissions in the system,laying the foundation for subsequent theoretical research.
