At The Westin Grand, in downtown Vancouver, BC, Canada, BACnet® integrates comfort controls with systems that manage the critical daily business processes in the lodging industry. Even better, the integration of the property management system, HVAC, and building automation systems is saving energy dollars without compromising guest comfort. In the lodging market, with its diverse components, the property management system is the hub of various freestanding yet vertically integrated subsystems that control reservations, billing, phones, housekeeping, and more, including comfort and energy consumption. A BACnet integration of the property management and building automation systems at the hotel saves energy by setting back temperatures in unoccupied rooms.
