Abstract

tUnderground transportation systems are big energy consumers and have significant impacts on energyconsumption at a regional scale. The literature has revealed that the energy consumption for non-tractionpurposes may be of the same magnitude as the energy used to move rolling stock, and in some cases evengreater. However, most of the research conducted so far has focused on the energy demand of rollingstock. This paper investigates the electricity consumption of an underground metro station using datafrom on-site surveys and measurements. With an average consumption of 217.64 kWh/m2/year, thebreakdown revealed that the lighting system dominated the underground station’s energy consumption(37%). Illuminated advertising signs were found to be responsible for 14% of the total energy consump-tion, and ventilation accounted for another 14%. The rest of the energy consumption was attributed tosystems such as mobile phone signal antenna (12%), the vertical transportation system (8%) and smallpower devices (5%). Accurate information on energy consumption for non-traction usage is useful forfuture implementation of energy conservation measures in underground stations, which could result ina reduction of operating costs in the long run.
