Having received its LEED Gold certification upon completion in 2006, the Hearst Tower
was New York City's first certified green skyscraper. Designed and built by Foster + Partners
, the striking 46-story blue tower sits atop the original stone base that was finished in 1926. During construction, nearly 85 percent of the materials removed from the building were recycled for future use, and the tower uses 26 percent less energy than a traditionally designed building.
