The Hyatt Regency Boston has managed to reduce its energy costs by 42 percent, from 12.3 million kWh to 7.1 million kWh, over the last decade, according to a report in Green Lodging News.
According to the report, the company invested $3 million in improvements to energy efficiency, equipment and infrastructure, while a local gas and electric utility company provided rebates to defray some of the initial costs.
The hotel recently won the Energy Star rating from the Environmental Protection Agency, putting it in the top quartile of comparable buildings in terms of efficiency, using 35 percent less energy and emitting 35 percent less carbon dioxide. The 498-room hotel is owned by owned by Chesapeake Lodging Trust though managed by Hyatt.
Much of the efficiency savings were driven by the hotel’s decision to replace it incandescent bulbs with LEDs. According to the report, the hotel replaced 1,000 T-12 bulbs with T-8s. Some fixtures were able to reduce their wattage from 50 watts to 3. The hotel also installed motion detector light switches in some areas.
The hotel also installed CO2 detectors, which helps the building to optimize its HVAC system. By knowing when CO2 levels are getting high, building management can vent outside air only when needed, increasing energy efficiency.
It is also moving to a passive environmental management system for its rooms, allowing HVAC systems to shut off automatically when the room is unoccupied, rather than relying on decisions from the front desk or room occupant.
The hotel is also composting its food waste, and recycling cans, bottles and cardboard.
Starwood Hotels has recently announced a commitment to reduce energy use by 30 percent, while Hilton Worldwide’s efforts to evaluate and analyze the environmental impact of its hotels led to $29 million in energy and water savings in 2009.
