CityCenter

THE STRIP. Although not set to open until late 2009, the MGM Mirage's $7 billion CityCenter project (a massive 18 million-square-foot development on the Strip) earns early recognition for working to receive LEED (Leadership in Energy and Environmental Design) certification. It will include water reclamation systems, recycling programs, energy-efficient lighting, and use only wood from sustainable forests. There will even be a cogeneration facility onsite, and the recaptured heat will be used to meet CityCenter's hot water needs.
