As an essential hub of urban power supply and distribution systems,substations cause a great amount of greenhouse gas emissions during construction,installation,operation,and maintenance.By studying the life-cycle carbon emissions of substation buildings,the carbon emission characteristics of substation buildings can be figured out,thus targeted energy-saving and carbon-reducing technical measures can be taken to reduce energy consumption and protect the ecological environment.The construction plan of Zhejiang Anji 110 kV Chengbei substation is analyzed,calculating its whole life cycle carbon emission,optimizing the carbon reduction in five aspects,including the plan layout,envelope design,structural design,HVAC design,modular design,and comparing with the original plan.The result shows that the total life-cycle carbon reduction with the overall optimization is 1 619 362.52 kgCO2e,the carbon reduction rate is 72.32%,among which the optimization of foundation and footing design and the optimization of HVAC design are the measures with larger total life-cycle carbon reduction,with carbon reduction of 650 400.80 kgCO2e and 440 897.60 kgCO2e respectively.
