You optimize ADR, fine-tune OTA channels, train desk staff, and manage occupancy daily. Yet the moment a guest checks out, that room continues burning energy as if it were fully occupied.
Housekeeping finishes, the door clicks shut, but the AC unit runs nonstop for hours, or days. Traditional thermostats don't know the room is vacant, but your monthly power bill certainly reflects it. Multiplied by dozens of empty rooms every night across all seasons, HVAC waste represents the single largest hidden leak on your operating statement.
In under 2 minutes, get a property-specific breakdown of exactly where your energy dollars are leaking, and what getting them back looks like.
