摘要：半地下變電站是城市能源供應體系中的重要設施。然而，半地下變電站在建設和運營過程中會產(chǎn) 生大量的碳排放，對環(huán)境造成負面影響。因此，本文對半地下變電站建筑全生命周期碳排放與減碳策略進行研究，結果表明該建筑單位面積碳排放量為 92. 835 kgCO₂/( m² ·a) , 其中，運行階段碳排放量占 83. 90% 。通過減碳策略，在建材生產(chǎn)和運輸階段減碳量分別為 18% ~ 34. 3%和32. 17% ~ 91. 14% 。在建造拆除階段，通過拆除回收鋼材可以回收鋼材碳排放量的 37. 85% ~ 68. 13% 。綠植可以產(chǎn)生 35. 295 tCO₂/a 的碳匯量。光伏每年可以減少碳排放量為 87. 705 tCO₂/a。本文研究成果為進一步降低半地下變電站建筑的碳排放提供理論基礎。

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.
