CityCenter officials say the U.S. Green Building Council has been awarded the second-highest LEED certification for the base structure of the casino development's retail mall.
The gold rating is the second highest rating available from the council, given to buildings that score between 60 and 79 points on a 100-point scale that evaluates a building's site, the materials and resources used to build it and design innovation, among other things.
An announcement is expected Monday that the Crystals mall achieved the Leadership in Energy and Environmental Design's Gold Core & Shell certification. Crystals is the fourth LEED-certified building at the $8.5 billion CityCenter project on the Las Vegas Strip.
