The Colonnade Hotel has completed an energy-efficiency upgrade that has yielded a 30 percent cut in energy use and a utility incentive from NSTAR for more than $460,000 with the help of Bluestone Energy.
The Boston Back Bay neighborhood landmark hotel expects to save $295,000 annually, and achieve a return on investment in two years.
Some of the ‘green’ upgrades installed by Bluestone include a new centrifugal chiller with frictionless air bearing compressors, and highly efficient LED lights, and electronically commutated motors in the guest room fan coil units. Bluestone Energy also developed and installed a new building automation system (BAS) that allows hotel personnel to view the building’s operational status in real-time over the Internet.
The hotel says with the ability to monitor its infrastructure in real time, management can detect problems quickly and adjust cooling for maximum efficiency. In addition, the new BAS will allow the hotel to control certain building functions through an Internet-enabled distributed architecture.
Hotel system upgrades have translated into energy savings for a number of hotels.
