〔Abstract〕 In hospital management, energy consumption is a critical component of operating costs, and effectively managing energy use to reduce these costs is a pressing issue for hospital administrators. The hospital's data-based smart energy management platform enables real-time monitoring, analysis, and optimization of energy consumption, thereby effectively lowering operating costs and improving energy efficiency. The authors explores the application value of this platform in controlling hospital operating costs, demonstrating that it not only reduces energy consumption and expenses but also enhances energy use efficiency. This promotes the sustainable development of hospitals and highlights the importance of information technology in modern hospital management.
