At the beginning of 2005, the final redesign and its new name—the Comcast Center—was unveiled. The building is named after its lead tenant, cable company Comcast, which makes the skyscraper its corporate headquarters. Leasing , Comcast takes up 89 percent of the building. The building features retail and restaurant space and a connection to the nearby Suburban Station. In Comcast Center's lobby is the "Comcast Experience", which is a high-definition LED screen that has become a tourist attraction. Designed to be environmentally friendly, the skyscraper is the tallest Leadership in Energy and Environmental Design (LEED) certified building in Philadelphia.
