About 7 World Trade Center

7 World Trade Center is located just north of the main site of the World Trade Center. With Lower Manhattan struggling to maintain its vitality as a leading business district before the rebuilding of the World Trade Center proper, 7 World Trade Center helped to jump-start the neighborhood’s resurgence both economically and sym-bolically after 9/11. The footprint of the old 1980s-era building was pulled back to open up Greenwich Street, restoring the view corridor from Tribeca to the island’s southern tip that had been blocked since the 70s, and creating a new public park.

The tower is notable for its innovative detailing and formal restraint. Artist James Carpenter worked with the architectural design team to create a curtain wall whose curved spandrels and reflective sills produce a unique optical effect. Both smaller and airier than its predecessor, the 52-story slender glass pylon sits atop transformer vaults which supply electricity to millions of users.

To accommodate the transformers’ intense airflow requirement, the podium wrapper is designed as a breathing, stainless steel surface that gleams by day and glows at night. Behind the podium screen are blue and white LED fixtures linked to motion sensors which vary the wall’s illumination in the evening as pedestrians pass by.

A special outside air intake system, which filters outdoor air (and air-conditioned air) through an activated carbon filtration sys-tem, was developed to ventilate all offices, providing a healthier indoor environment for occupants. One of the first projects accepted as part of the U.S. Green Building Council’s Pilot Program for Leadership in Energy and Environmental Design (LEED) for Core and Shell Development, 7 World Trade Center is the first LEED Gold certified high-rise office building in New York City. The tower is also a model for life safety, with a reinforced concrete core, steel superstructure, and safety enhancements that exceed NYC building codes.

Standing tall as a simple yet nuanced contribution to the Manhattan cityscape, 7 World Trade Center sets a new standard for high-rise structures as it announces the Financial District’s sustainable resurgence.
