BILLY PENN A small replica of City Hall’s William Penn statue was installed on the highest steel beams in late 2017 in order to avoid the “Curse of Billy Penn” — a legend that no Philly team could win a sports championship if there were buildings higher than the statue’s head.

ECO-FRIENDLY The Comcast Technology Center tower acheived LEED gold level certification for energy efficiency by incorporating specific design elements. Floor plans and window structures are designed to optimize natural light penetration into the core of the building, reducing energy needed for lighting. The design also includes “green” roofs to minimize rainwater runoff.

ROBERTSES’ HOME Brian Roberts and his wife, Aileen, bought three condo units — the entire 45th floor.

COMCAST OFFICES Comcast’s 4,000-plus employees are grouped in three-floor “lofts” on floors 6 through 44 that correspond with a department or specific function. Each loft features a three-story open atrium meeting and pantry space at the east end of the building. Each loft has a unique interior decoration scheme designed by local artists. Open stairways in the atriums provide quick inter-floor access and encourage workers to walk rather than use the elevators.
