“…), and combine virtual space theory with traditional physical space design methods to form a new urban design method system for use in new situations ( Sanchez-Sepulveda, Fonseca, Franquesa, & Redondo, 2019 ). The integration of big data ( Rahman et al, 2020 ), GIS (Geographic Information System) ( Badach, Voordeckers, Nyka, & Van Acker, 2020 ), dynamic simulation methods for virtual space ( Sanchez-Sepulveda et al, 2019 ; Singh, Kaur, & Kumar, 2020 ) as well as fast prediction models ( Feng, Yu, & Cao, 2019 ; Cao, Yu, & Luo, 2020 ) can be used to build a quantitative group-tool for urban design under the normalization phase of epidemics. Taking satellite cloud map from remote sensing technology and GPS (Global Positioning System) data as input variables, the thematic visualization map of the studied area can be finally output ( Shao, Huq, Cai, Altan, & Li, 2020 ).…”

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.

The outbreak of pneumonia caused by 2019 Novel Coronavirus arises significant concern for virus transmission and control. The control of the indoor environment or public-enclosed environment is crucial to reduce the risk of infection. Heating, ventilation, air-conditioning (HVAC) systems are used to create a healthy, thermal-comfort indoor environments. Thus, the rational use of HVAC systems is of great importance for the environmental control to reduce infection risk and to improve human wellbeing in the pandemic. In order to satisfy the requirement of better healthy environment and more thermal comfort performance of indoor ventilation system, prevention of indoor pollution is essential, especially considering the purpose of disease transmission resistance. This paper investigated the collective contagion events in enclosed spaces as well as engineering control against virus spread with ventilation systems for health-care facilities and public vehicles. Future challenges of HVAC design and control were discussed.
