The New York City EMT cleared out the Admissions Lobby and made it into a triage center for victims of the attack.[53] Many of the patients were New York City police officers, firefighters and other emergency workers. Debris and about three inches (7.5 cm) of dust and ashes laid over the Pace New York City campus area and local streets. None of Pace's buildings were damaged except in the World Trade Center; Pace lost the entire 55th floor, 45,943 square feet (4,268.2 m2)[54][55] in the North Tower of the World Trade Center which used to house Pace University's World Trade Institute and the Pace University World Trade Conference Center[56] (now the Downtown Conference Center).
