Comcast Center is the new headquarters for the Comcast Corporation, with typical floor plates ranging between 2,140 and 2,600 square meters (23,000 and 28,000 square feet). Taking the form of a faceted obelisk, the tower is clad in silvery high-performance glass with ultra-clear, low-iron glass at the building’s corners and crown. The Comcast Center and its south-facing, half-acre plaza straddles the underground tracks and concourse of Suburban Station —Philadelphia’s primary commuter rail gateway.

A 110-foot-high, light-flooded public winter garden connects the concourse with its shops and food hall to the tower and plaza above. The winter garden features a double-skin glass curtain wall with sunscreens and louvers which optimize daylight and views while modulating daily and seasonal thermal performance. Radiant heating, thermal extraction, and displacement ventilation combine to provide exceptional energy performance for this civic-scaled space. Three 3-story “sky atria” in the lower portion of the tower’s south façade overlook the plaza and provide tenants with unique and identifiable homes. The building is expected to receive LEED-CS Certification.
