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.Through the implementation of energy and water savings measures, these partners have amassed a savings of $290 million since 2011.
