The test sought to measure the HVAC and lighting energy savings that could be realized by utilizing sensor and control devices that respond to hotel room occupancy statuses.
The Verde hotel room energy system determines if a hotel room is vacant or occupied, according to the status of the system’s Keycard Access Switch. When a guest enters a hotel room and inserts their key card into its dock, a radio signal is sent that alerts the system the room is occupied. When the guest leaves the room unoccupied, the removed key card automatically shuts off controlled lights and/or electronics, and sets the in-room HVAC system back to its unoccupied/energy-conservation mode. In the Wyndham Hotel study, four hotel rooms were monitored. Two were retrofitted with Verde system controls and the other two were used as independent control rooms. HVAC and lighting energy consumption was analyzed over a period of 30 days. The Verde-equipped room used 33% less energy for HVAC and electronics than the control room. With the implementation of the Verde Energy Control System in all 293 rooms, the hotel will save 480,991 kWh annually. The Verde Energy Control System additionally helps hotels comply with energy standards such as CA Title 24 and ASHRAE/IESNA standard 90.1.
Verde will be represented by Magnum Energy and will attend the International Hotel/Motel & Restaurant Show in New York, from November 8 to November 10, 2009 in booth 3084.
The EnOcean Alliance wireless standard used in this study is anchored by interoperability. This is in contrast to alternative wireless standards that allow proprietary solutions to be marketed as compliant, leading to unwelcomed surprises when devices manufactured by multiple vendors are discovered to not work together.
