4 World Trade Center (also known by its street address, 150 Greenwich Street) is a skyscraper that is part of the new World Trade Center complex. It opened to tenants and the public on November 13, 2013.

The original, nine-story 4 WTC was destroyed on 9/11, so its replacement, a glimmering glass tower designed by the legendary Fumihiko Maki that opened to the public last October, is all about renewal—in more ways than one. Indeed, 100 percent of the energy used in the building comes from renewable sources like solar and wind. And hey, business world, there’s still plenty of office space available.
