Commitment to conservation

With over 4,000 hotel rooms, the ARIA Resort & Casino is the world’s largest hotel to achieve a LEED Gold rating. The building’s primary energy-saving feature is its curtain wall, which uses a new generation of glass coatings that let daylight in while blocking the sun’s heat-producing rays. Water efficiency is also a key achievement. More than 117,000 cubic meters (31 million gallons) of water are saved throughout the resort each year. This includes savings of 40 percent in the hotel and 60 percent for landscape irrigation by U.S. standards.
