With the increasing variety and quantity of energy consuming equipment in hospitals, the phenomenon of high energy consumption in hospitals is becoming increasingly prominent. In June 2021, this study established an energy consumption control strategy for hospitals based on the energy consumption characteristics of medical service units, targeting the current situation and shortcomings of hospital energy consumption management, and then conducted exploration of strategy application. The strategy was designed to deepen the analysis of the energy consumption hierarchy and energy consumption characteristics of medical service units in the hospital′s energy consumption system, extract personalized energy consumption control indexes, and optimize or build energy consumption control systems with the help of self-control and information technology, through collaboration among multiple departments. These measures above aimed to reduce ineffective energy consumption in the energy consumption terminal of medical service units, promote the deep integration of energy consumption system operation status and energy consumption demand characteristics of medical service units, and realize precise energy consumption control.In June 2021 and March 2022, two tertiary hospitals carried out energy consumption control practices based on the energy consumption characteristics of operating rooms and wards respectively. After practices, the energy-saving rates of operating rooms and wards were both>10.0%, achieving good application results. This strategy can provide references for hospitals in China to promote energy conservation and emission reduction.
