Cabin management

Smart cabin control on real passenger demand

Passenger load is constantly moving, and not every cabin needs the same level of ventilation and climate control at the same time. The Cabin Management System adapts operation based on cabin status, occupancy and actual demand.

The system operates around two main states: booked and not booked. When a cabin is booked, the cabin controller keeps the room ready for use, automatically managing heating, cooling and fresh air according to real-time occupancy — using CO₂-based presence detection to identify when the cabin is in use and open up fresh air supply as needed. When a booked cabin is temporarily empty, airflow and energy use are reduced while the room stays ready for the guest’s return.

When a cabin is not booked, the system automatically enters an energy-saving state: ventilation is minimized, temperature is allowed to operate within a wider deadband, and functions such as bathroom floor heating and lighting can be reduced or switched off.

By connecting cabin fan coils, VAV dampers, booking system information and CO₂-based presence detection with local cabin control, the Cabin Management System follows the moving passenger load automatically — reducing unnecessary energy consumption while maintaining comfort exactly where and when it’s needed.
