With 24-hour 365-day operations, hotels are one of the highest energy and water consumers per square foot. Better Buildings Hospitality partners represent 1 billion square feet of the sector's total 6 billion square feet of national floorspace. Across America’s 47,000 hotels, it is estimated that the average guest room incurs nearly $2,200 in energy costs annually. By investing in and prioritizing energy efficiency, hoteliers can improve guest comfort and realize cost savings.

Case Studies

TownePlace Suites discovered an unused four-acre piece of land adjoining one of its properties, and developed the land with a solar installation, decreasing electric costs and improving the hotel’s environmental reputation.
Bardessono, a hotel in Yountville, California was designed to be one of the most energy efficient hotels in the world. A major roof-top solar array was included in the design to achieve significant energy savings and LEED Platinum certification. The PV system produces approximately one-half of the electricity used by the hotel.
Wastewater recycling is a market-ready solution that can save commercial washers an average of 365 thousand gallons/month of combined water and sewer and 1,100 therms/month in hot water heating energy.
DOE funded evaluations of ozonation at the Charleston Place Hotel in Charleston, SC, and the Rogerson House assisted living facility of Boston, MA and found up to 60% savings in hot water requirements.
The Hampton Inn & Suites Bakersfield North- Airport operates in a hot climate and has high HVAC operating costs. To mitigate these costs, a carport solar array was installed, producing monthly savings of $8,800.
DOE funded evaluations of a wastewater recycle system at the Grand Hyatt Seattle and of ozone systems at the Charleston Place Hotel and the Rogerson House Assisted Living Facility, saving $135,000 in the first year.
MGM Resorts decided to augment their retrocommissioning (RCx) efforts by installing fault detection and diagnostic (FDD) software, which identifies building systems with suboptimal performance. Beyond the significant energy savings, the addition of analytics has changed the organization’s energy management culture, and allows for accurate, actionable reporting at all levels of the organization.
Hilton's 5,100 properties across 103 countries are ISO 50001 certified, saving the company nearly $740 million in 8 years.
MGM lighting projects have covered more than 8 million square feet of parking area. By replacing 4,400 metal halide and high-pressure sodium light fixtures in the parking facilities with a mixture of LED and induction fixtures, MGM saved 4.5 million kWh per year as part of the Lighting Energy Efficiency in Parking (LEEP) Campaign.
