Analysis of current situation of energy consumption and energy saving potential of a utility tunnel

The energy consumption of a new comprehensive utility tunnel in Beijing is analysed based on the monitoring data of energy consumption. The energy consumption structure of the utility tunnel is clarified through energy consumption splitting. The energy consumption of the utility tunnel is preliminarily optimized and the optimization result verifies the accuracy of energy consumption splitting. At the same time, the research results also expose some problems existing in the design, operation and maintenance of the utility tunnel, for which some preliminary suggestions are made to provide a reference for the subsequent design and energy saving operation and maintenance of the utility tunnel.
