摘   要： 半地下变电站是城市能源供应体系中的重要设施 。然而，半地下变电站在建设和运营过程中会产 生大量的碳排放，对环境造成负面影响。因此，本文对半地下变电站建筑全生命周期碳排放与减碳策略进行研究，结果表明该建筑单位面积碳排放量为 92. 835 kgCO₂/( m² ·a) , 其中，运行阶段碳排放量占 83. 90% 。通过减 碳策略，在建材生产和运输阶段减碳量分别为 18% ~ 34. 3%和32. 17% ~ 91. 14% 。在建造拆除阶段，通过拆除回 收钢材可以回收钢材碳排放量的 37. 85% ~ 68. 13% 。绿植可以产生 35. 295 tCO₂/a 的碳汇量 。光伏每年可以减少 碳排放量为 87. 705 tCO₂/a。本文研究成果为进一步降低半地下变电站建筑的碳排放提供理论基础。

Abstract: Semi-underground substation buildings are important facilities in urban energy supply systems. However, significant carbon emissions are generated during construction and operation, negatively impacting the environment. The lifecycle carbon emissions and carbon reduction strategies of semi-underground substation building is studied in this paper. The results show that the carbon emissions per unit area of the building is 92.835 kgCO₂/(m²·a), of which the carbon emission in the operation phase accounts for 83.90% of the total. The reduction of carbon through the carbon reduction strategy is 18%-34.3% and 32.17%-91.14% in the production and transportation phases of building materials, respectively. During the construction and demolition phase, 37.85%-68.13% of the carbon emissions of steel can be recovered by dismantling and recycling steel. The greenery can generate a carbon sink of approximately 35.295 tCO²/a. Photovoltaics can reduce carbon emissions by approximately 87.705 tCO²/a. The findings of this paper provide a theoretical basis for further reducing carbon emissions from semi-underground substation buildings.
