|Many energy controls and sensors work together wirelessly, making installation viable for existing properties.|
Contemporary energy control systems are managed over property-management systems or building-management systems, and those systems are not limited by the construction of a hotel property. For existing properties averse to installing new wiring, there are wireless thermostats available that communicate with HVAC units over RF waves, passing messages from one thermostat to another until they reach a hot spot and can interact with the property.
According to Warren Dehan, president of Northwind-Maestro, this allows the guestroom to interact directly with a property’s PMS system, controlling not only the atmosphere of the guestroom but also the power allotted to services such as the minibar and guestroom TV, limiting their activity in un-rented rooms. Hotels can use these systems to mediate their energy use while getting rooms comfortable for guests at a moment’s notice. John Tavares, director of marketing at Inncom, suggested pre-cooling a room to a temperature near what is expected at check-in, and then having the occupancy sensors control when to enlist full power from the HVAC. “Even if you keep the room at 74 degrees rather than 70, it creates an environment that on guest entry takes minimal time to get to the desired temperature while providing large savings,” Tavares said.
