Operations and Maintenance Management System and Institutional Development
Establishing a comprehensive MEP system O&M management system is the foundation for ensuring efficient system operation and controlling O&M costs. The O&M management system should encompass four dimensions: organizational structure, institutional processes, technical standards, and performance assessment. Regarding organizational structure, the hotel engineering department should establish specialized teams for HVAC, electrical, plumbing, and low-voltage systems. Regarding institutional processes, equipment inspection systems should be established (daily inspection of critical equipment, weekly inspection of general equipment), periodic maintenance systems, and fault repair reporting systems. Performance assessment should establish an O&M KPI system including equipment availability rate (above 98%), fault repair time, etc.
Energy Management and Cost Control
Energy costs account for 50%-60% of total O&M costs, making them the primary O&M expenditure. Key energy management measures include energy consumption monitoring, energy efficiency optimization, and energy-saving retrofits. Establish a sub-metering system for separate metering of air conditioning, lighting, power, hot water, etc. The air conditioning system dynamically adjusts chilled water supply temperature based on outdoor temperature and occupancy rate; each 1 degree increase raises unit COP by approximately 3%. Each 1 degree decrease in cooling water inlet temperature raises unit COP by approximately 2%. The lighting system adopts intelligent dimming control.
Equipment Maintenance Strategy and Cost Optimization
Equipment maintenance strategies can be divided into three levels: reactive maintenance, preventive maintenance, and predictive maintenance. Critical equipment (chillers, boilers, transformers, elevators) adopts a combination of predictive maintenance + preventive maintenance; general equipment (pumps, fans) adopts preventive maintenance; low-value consumable equipment adopts reactive maintenance. Predictive maintenance requires detection equipment such as vibration analyzers, infrared thermal imagers, and oil analysis instruments to conduct periodic monitoring of key parameters of critical equipment.
Spare Parts Management and Cost Optimization
Spare parts costs account for approximately 10%-15% of total O&M costs. Spare parts are classified into wear parts (filters, belts, etc.), common parts (bearings, valves, etc.), and strategic parts (compressors, control boards, etc.). Spare parts management adopts the ABC classification method: Class A spare parts (high value, low quantity) have strictly controlled inventory levels; Class B spare parts (medium value) have moderate control; Class C spare parts (low value, high quantity) have loose control. Wear parts adopt framework agreement procurement to reduce unit prices.
