“…Underground transport infrastructure has often been used to regenerate urban land to improve mobility, accessibility and connectivity. Underground railways and stations, underground parking spaces and underground pedestrian networks are the main forms of this utilisation (Cui and Nelson, 2019). In many cities in the world, due to narrow roads and traffic congestion, using UUS has proven to be a wise choice for improving mobility and accessibility.…”

The rapid increase in world population in the 21st century, with associated transport and environmental problems, has encouraged the development of urban underground spaces as an optimal solution in many occasions, including urban renewal schemes. This paper reviews literature on the utilisation of urban underground space for urban renewal to provide a better understanding of how urban underground space can contribute to urban renewal, and of challenges and successes in achieving the goals. The paper concludes that urban underground space present new development opportunities (e.g. land/space supply, less traffic congestion, compact city development, and urban sustainable development) in regeneration of existing urban land. Urban underground spaces, as valuable resources and efficient and effective tools for urban renewal, should be considered by decision-makers for transforming existing urban areas, stimulating vibrant and denser development and mixed land use.

“…On the other hand, market factors such as demand, average transportation cost, and delivery time determine the market share of M-ULS ( Hu et al, 2020b ). In particular, restrictive and incentive policies dynamically affect supply and demand in the freight market, which makes modelling more difficult ( Cui and Nelson, 2019 ). In short, the simulation of the M-ULS includes nonlinear and dynamic behaviors and feedbacks among multiple stakeholders in multiple scenarios.…”

In subway stations, the piston effect plays an important role in enhancing ventilation to improve subway environment and reduce energy consumption. However, it may induce negative impacts on environmental health and thermal comfort, i.e. air pollution and strong wind. Traditionally, the architecture and ventilation systems are designed separately, and normal ventilation design follows architectural layout. Actually, the architecture design can have a significant influence on the ventilation performance, e.g. airflow pattern. Therefore, this study aims to integrate the design pattern of the architecture with an appropriate ventilation system. A typical subway station of Nanjing (in China) was considered. A dynamic-mesh based computational fluid dynamics (CFD) method was adopted to simulate ventilation performance in the presence of piston effect. Field measurements were conducted to validate the numerical method. New measures were proposed from the perspectives of architectural design to improve the ventilation effect, including enlarging atrium space, adding atrium vents and funnel-shaped exits, etc. The numerical results show that the optimal architectural design could provide a significant improvement towards the airflow environment and ventilation efficiency while avoiding serious air pollution. The proposed integrated-design pattern could further facilitate the creation of an ‘energy-saving’ and ‘healthy’ underground space environment.
