1. HVAC Systems: DDC cabinets regulate air conditioning, heating, and ventilation in offices, malls, and hotels. They adjust temperature, humidity, and airflow based on real-time data from room sensors, optimizing energy use while maintaining comfort (e.g., lowering cooling intensity in unoccupied zones).
2. Lighting Control: Integrated with motion sensors and timers, DDC cabinets manage lighting in lobbies, corridors, and meeting rooms. They automatically dim or switch off lights in vacant areas and sync with building schedules (e.g., brightening offices at 8 AM) to reduce energy waste.
3. Plumbing & Water Management: In commercial buildings, DDC systems monitor water flow, pressure, and tank levels in restrooms, kitchens, and irrigation systems. They trigger alerts for leaks or overflows and adjust pump operations to ensure efficient water distribution.
4. Elevator & Escalator Coordination: DDC cabinets link with elevator systems to optimize usage—adjusting elevator dispatch frequency based on peak hours (e.g., morning commutes in office towers) and putting idle units in standby mode to save power.
5. Security & Fire Integration: They interface with fire alarms and security systems to activate emergency protocols. For example, in a fire, DDC triggers stairwell lighting, shuts down non-essential HVAC to prevent smoke spread, and unlocks emergency exits.
6. Energy Monitoring & Reporting: DDC cabinets collect data on power, water, and HVAC usage, generating reports for facility managers. This helps identify inefficiencies (e.g., excessive lighting in unused floors) and supports data-driven energy-saving strategies.
