Energy Consumption Investigation and Analysis on Coach Stations in Tianjin

Coach station has the characteristics of high-density passenger flow, long operation time, large number of energy-consuming equipment and so on, which leads to the problem of high energy consumption. Based on the field investigation of six coach stations in Tianjin, the general building information such as architecture overview, major energy-consuming equipment, energy construction and consumption was obtained. The total energy consumption and sub-item energy consumption of each coach station were analyzed and calculated according to the investigation data. The results showed that the annual total energy consumption per unit area of the coach stations in 2017 ranged from 41.55 kWh/(m²·a) to 128.08 kWh/(m²·a), with an average of 76.53 kWh/(m²·a). The heating, ventilation and air conditioning (HVAC) system were the main component of building energy consumption, accounting for an average of 68.26% of the total energy consumption, indicating that the HVAC system of this type of buildings had a great potential for energy saving and reconstruction. Analyzed by the statistical software SPSS, the air conditioning form and heating form were significantly related to the total annual power consumption per unit area.
