Abstract

Urban rail transit stations in hot and humid regions of South China release considerable amounts of anthropogenic heat (AH). However, the components of AH, including their calculation methods and temporal characteristics, have not been sufficiently investigated. In this study, the components of AH from Qingsheng metro station were calculated using a combined approach (i.e. the bottom-up inventory method and the comprehensive heat transfer coefficient method) based on statistical station operation data and the field measured meteorological data. Then, the hourly AH and its components were estimated. The results showed that QM and QT exhibited dual peaks, whereas QB and total AH exhibited a single peak during the operation period (06:00–24:00). The maximum values of AH at 12:00 were 35.15 W•m−2. Among the three components, QB contributed the greatest to AH, followed by QT and QM. A comparison of AH with the absorbed solar radiation by the horizontal envelope indicated that AH should be considered to be an important heat source in urban rail transit stations.
