ATLANTA—Atlanta Marriott Marquis has implemented several high-tech energy saving management systems. Beginning this month, all 1,569 guestrooms and 94 suites will feature a door switch and a motion detecting thermostat that are tied into the central energy management system server (EMS). Upon door switch activation, the motion detector looks for movement. Once movement is detected, the room goes into occupied mode and the guest has full control of the guestroom heating and cooling. When the door switch is activated upon the guest leaving the room, the motion detector automatically searches for movement and if none is detected, the temperature range is slowly moved to the unoccupied mode. INNCOM provided the occupancy Sensors.
Heat and smoke sensors installed in six kitchen hood systems control the speed of the exhaust fans and air handler for the bake shop, room service, cafeteria, and the main kitchen hood exhaust systems. The name of the sensors: Melink Intelli-Hood System.
The property replaced 187 steam traps throughout the building. The new steam traps have no moving parts, utilizing a venture nozzle to separate the condensate from the steam. Eleven percent consumption savings are attributed to the new traps.
Motion Detectors in Meeting Rooms
Motion detectors installed in 48 meeting rooms activate a communication protocol from the hotel’s energy management system to coordinate with the lighting dimming system software to turn off the lighting when the room is not sold and no motion is detected.
Motion detectors and dimming ballasts were installed in all of the hotel stairwells and 926 motion detectors were installed in all back of the house associate areas.
