7 World Trade Center

7 World Trade Center's attachment to New York history is right there in its name, but this magnificent new 52–story high rise's technical and architectural innovations have already made it a bright beacon of sustainability in Manhattan.

7 World Trade Center’s dedication to efficiency was evident from the start, as the surpassingly green construction process — which featured low-sulphur fuels in construction system and a bevy of recycled materials and sustainably harvested wood used in the construction itself — won the project EPA Environmental Quality plaudits back in 2004.

7 World Trade Center has remained at the forefront of green building ever since thanks to floor-to-ceiling low-iron glass windows on every floor of class A office space, super-efficient plumbing and electric systems and an ultra-modern HVAC system that uses rainwater collected on the rooftop both to cool the building and provide irrigation to a nearby park. Those innovations have kept 7 World Trade Center in the vanguard of Manhattan’s green scene. They’ve also helped 7 World Trade Center continue to pile up honors — 7 World Trade Center was the first building in Manhattan to earn LEED Gold certification when it received the honor back in 2006, and its continued operating efficiency earned Energy Star honors from the EPA in ’08.

And, of course, 7 World Trade Center is beautiful — a stylishly slender, airy glass pylon that rises above an elegant 45-foot stone and glass entry lobby to provide views that stretch the very length of Manhattan. Steeped in New York history and emblematic of Gotham’s green future, 7 World Trade Center is already a landmark — rising proudly in a familiar place, 7 World Trade Center’s combination of beauty and sustainability makes it a building all New Yorkers can be proud of.
