Abstract

In response to the dual-carbon strategy, the construction industry is actively exploring methods to save energy and reduce emissions. As industrial buildings, the design methods and operating conditions of substation buildings are significantly different from those of typical civil buildings. The low-carbon design methods of common civil buildings cannot be simply and directly applied to substation buildings. In this study, a parametric approach is adopted to firstly obtain the initial design scheme, clarify the types and ranges of design variables, and generate multiple alternative design schemes. Secondly, the carbon emissions of the physical and operational phases are calculated separately. Finally, the optimal solution is screened by genetic algorithm to achieve the low-carbon optimal design of substation buildings. In this study, the low-carbon optimal design method is applied to a typical 110kV reinforced concrete substation building. The results show that the optimized design can reduce carbon emissions by 17%. This research provides technical support for the low-carbon transition of the power and construction industries.
