Generation mechanism of green low-carbon evaluation system for rail transit hub and itsapplication in Beijing Sub-central Station

Abstract:
In the context of China’s dual-carbon policy objectives, rail hubs, as critical components of urban infrastructure, play a significant role in promoting energy conservation and reducing carbon emissions. As China’s transportation sector continues to experience steady growth in passenger traffic, the associated energy consumption has reached unprecedented levels, especially with the rapid expansion of new railway lines. This has exacerbated the challenges of increasing urban energy demand and resource consumption. The large spatial scale of rail hubs, coupled with the complexity of energy consumption influencing factors, further underscores the urgency of addressing these issues. However, China’s current standards and regulations for evaluating the green and low-carbon performance of rail hubs remain incomplete and underdeveloped, making it difficult to systematically assess and promote sustainable practices. This paper aims to address this gap by focusing on the green and low-carbon evaluation of rail transportation hubs during the pre-construction phase. We begin by identifying and analyzing the key issues hindering green development in China’s rail hubs, examining them across three main dimensions: the natural environment, human factors, and technological innovation. These dimensions encapsulate the major challenges related to energy efficiency, resource management, and sustainability that need to be addressed for a more environmentally friendly rail hub infrastructure. To develop a more robust and comprehensive evaluation system, the study collects and analyzes data from case studies of existing rail hubs, focusing on their green and low-carbon performance. Based on these findings, it proposes an evaluation index system that includes three core dimensions: natural environmental factors, humanistic environmental factors, and scientific and technological innovation factors. This system comprises six first-level indexes and seventeen secondlevel indexes, allowing for a detailed and nuanced assessment of a rail hubs sustainability performance. To further refine this evaluation system, it applies the entropy value method to calculate the weight of each evaluation index, ensuring an objective and data-driven approach to the assessment. In addition, it incorporates the theory of material elemental topology to build a more complete and integrated green and low-carbon evaluation model for rail hubs. This model offers a systematic framework for evaluating the sustainability of rail transportation infrastructure and can be adapted to various project scales and contexts. The proposed evaluation model is applied to a realworld case study of the Beijing Urban Sub-city Development Area, specifically the Beijing Urban Vice Center Hub project. By utilizing the evaluation results, it provides practical and feasible recommendations for improving the design scenarios of this major infrastructure project. These suggestions are grounded in both theoretical research and empirical analysis, offering actionable insights that can be implemented to enhance the project’s environmental sustainability. In conclusion, the research presented in this paper aims to contribute to the development of more effective and comprehensive standards for evaluating the green and low-carbon performance of rail hubs in China.The findings are intended to serve as a reference for future research and engineering practice, promoting more sustainable and energy-efficient transportation infrastructure in alignment with national carbon reduction goals.
