We’ve been following the progress of One World Trade Center closely, and this weekend we were excited to see some of the first signs of sustainability pop up at the construction site. More than 2,000 state-of-the-art, “green technology” glass panels are being installed on the street level podium wall of 1 WTC, which is scheduled to be complete by the end of the year. These high-performance panels are double-paned and made with a frosted coating for absorbing sunlight and minimizing heat gain.
“This [glass] has much more high-end lighting behind it, it’s much more efficient from an energy point of view, and it also has a third dimension to it,” said Steven Plate, the Port Authority’s director of World Trade Center Construction to the Tribeca Citizen.
The building base is also impressively built to withstand up to 900 pounds of TNT and is made from a type of concrete known as iCrete, which is mixed in Brooklyn and must arrive on-site within 90 minutes. This new concrete also has the ability to withstand an astounding 14,000 pounds-per-square-inch (psi) of pressure.
The European-made green glass will cover the entire ground level of the 186-foot base of the new “bomb-proof” building, and will be just a portion of 1 WTC’s sustainability initiatives. The new shiny green panels will enclose the concrete mix of materials used to rebuild the World Trade Center, which will be the toughest structure ever created in New York City.
