Environmental health in subway stations, a typical type of urban underground space, is
becoming increasingly important. Ventilation is the principal measure for optimizing the …

Due to the rapidly increasing ridership and the relatively enclosed underground space, the
indoor air quality (IAQ) in underground subway stations (USSs) has attracted more public …

For the past 20 years, particulate matter (PM) pollution has been a national concern in South
Korea. In particular, indoor PM concentrations may contribute significantly to human …

Mechanical ventilation has been widely implemented to alleviate poor indoor air quality
(IAQ) in confined underground public facilities. However, due to time-varying IAQ properties …

Missing data represents a common problem in environmental and building-related
processes, especially in the indoor air quality (IAQ) system of subway stations, where the …

The metro is an indispensable transportation system in big cities and the primary commuting
method for city residents. Ventilation primarily controls metro environmental health. The …

Indoor air quality (IAQ) is an important factor for determining quality of life and urban
sustainability. In underground subway stations, improving IAQ through ventilation systems …

With the development of the society, train travels in underground, mountain, and undersea
tunnels are common public-transportation scenarios. Relative research such as ventilation …

Unorganized ventilation significantly increases the energy consumption of subway stations.
Many factors affect unorganized ventilation, and its variation is still not clear. This study …

The pollution status of particulate matter (PM) in a subway system and technological trends
in their reduction were discussed in this study. The levels of PM2. 5 and PM10 are generally …
