The Palazzo Las Vegas 50-story hotel-casino-shopping complex has been awarded Silver LEED certification by the U.S. Green Building Council (USGBC), making it the world's largest LEED certified building. The $1.9 billion complex includes 3,000 suites, an 85,000 -sq.-ft. department store, more than 80 shops, restaurants, a theater, spa and Las Vegas' first Lamborghini dealership.
According to USGBC, The Palazzo is not only the largest LEED-certified building in the world, but is over four times bigger than the second-largest. "The Palazzo is to be commended for achieving LEED certification. This facility is one that both the community and its guests can be proud of," said Rick Fedrizzi, president, CEO and founding chair of US GBCU.
A wide array of energy-saving plumbing and heating technologies helped The Palazzo to earn its LEED rating, including:
Artificial turf, drip irrigation and moisture sensors in planted areas result in over a 75% reduction in irrigation needs.
Swimming pools at The Palazzo are heated with an expansive solar pool heating system. In the summer, the excess solar energy not needed for the pools is directed to the hotel's hot water system, reducing the need to heat water for guest suites.
Air conditioning controls in guest suites that automatically setback by several degrees when guests are not present and reset to the desired temperature upon return.
Interior plumbing fixtures use 37% less water than conventional buildings as a result of water-efficient showerheads, high efficiency toilets and low-flow lavatory faucet aerators.
Moisture sensors monitor real time, site specific air temperature humidity, rainfall and other factors to provide daily watering cycle adjustment.
The Palazzo employs such effective environmentally-efficient technologies that it conserves enough water to provide each Nevada citizen with 266 eight-ounce glasses of water for a year and saves enough energy to light a 100 watt light bulb for 12,100 years, according to Las Vegas Sands, the buildings owner. It even promotes alternative modes of transportation by offering valet parking - for bicycles.
