Watching your bottom line and carbon footprint

Hotels are often told of the savings they could have to both the environment and their bottom line by installing energy management procedures and practices. Modern systems have managed to finally link cost-effectiveness with environmental sustainability, though many properties are still struggling to grasp what the best way is to control the energy output of the hotel guestroom.

According to John Tavares, director of marketing at Inncom, motion detectors and door switch sensors are commonly used in collaboration with one another in the guestroom.

“You want the algorithm to err on the side of the guest,” Tavares said. “If the door switch is triggered, you want to delay the energy-saving systems from kicking in for a few minutes just in case the guest left the room for a few seconds.”

Door sensors inform the hotel’s energy management system that a guest either exited or entered a room, but paired with a motion detector they can be sure of the guest’s presence. If the door triggers and there is no motion, the guest is gone. Though this is effective, software can be used to assist sensors in finding guests when occupancy may not be apparent.

Michael Serour, VP of sales and marketing for Verdant Environmental Technologies, argued that door sensors are unnecessary, maintaining that a software approach is a more effective way to combat the challenges of night occupancy.

“After eight or nine at night, our software can be configured to enter our patented ‘Night Occupancy’ start time,’” Serour said. “It’s unlikely anyone going into a guestroom after nine is staff, and if they are spending any amount of time in the room they will be considered a guest and will be acknowledged by the sensors. Once these conditions are met, energy savings will be disabled until the end of Night Occupancy Mode.”

Night Occupancy Mode is one of 60 international patents owned by Verdant Environmental Technologies.

According to Chris Pieper, director of sales and marketing at Evolve, the majority of a hotel’s energy savings is received through management of the property’s HVAC system. Modern thermostats and controls can be installed to help manage HVAC systems in both new builds and existing properties, making savings on energy and  environmental savings possible for anyone.
