The Palazzo Las Vegas has been recognised as the largest LEED-certified building in the world.

The Leadership in Energy and Environmental Design, awarded by the US Green Building council , recognising the energy efficient technologies deployed at the SANDS hotel.

The Palazzo employs such effective environmentally-efficient technologies that it conserves enough water to provide each Nevada citizen with 266 8oz glasses of water for a year and saves enough energy to light a 100W light bulb for 12,100 years.

Key features include the use of artificial turf; drip irrigation and moisture; air conditioning controls in guest suites that automatically setback by several degrees when guests are not present; moisture sensors; site-specific air temperature and other factors to provide daily watering cycle adjustment; and the provision of valet parking-for bicycles.

The LEED Green Building Rating System is the nationally accepted benchmark for the design, construction and operation of high-performance green buildings.

LEED certification provides independent, third-party verification that a building project is environmentally responsible, energy-efficient and a healthy place to live and work.
