Description
Summary:Metro transportation systems are significant energy consumers. Apart from the traction system, considerable amounts of electricity are consumed in metro stations. In the present study, energy audits of two Athens metro stations were conducted to ensure a detailed overview of energy consumption per stationary load. Data from on-site surveys as well as real-time measurements were elaborated. The energy profile over time was developed for the measured electrical loads. Results have shown that the total energy consumption of Sepolia and Peristeri stations was 117.09 and 99.17 kWh/m 2 /year respectively, as well as 0.12 and 0.52 kWh/passenger/year. Lighting and small power were significant consumers (23.3% of total energy consumed in Sepolia station, 51.5% in Peristeri station). The natural, piston effect induced ventilation system in Peristeri station showed significantly lower energy consumption (7.4%) than that of Sepolia station (25.9%) using forced ventilation for stations and tunnels.
