PNC Bank Headquarters, Pittsburgh, PA
THE LARGEST NORTH AMERICAN LIVING GREEN WALL!

The PNC wall is a living, breathing wall of plants spanning 2,380 square feet on the south side of the bank's Pittsburgh headquarters, at the corner of Fifth Avenue and Wood Street.

The wall is made up of 602 two-foot square panels. Each panel contains 24 evergreen plants. "The vertical garden, similar to a green roof, will help to cool the 30-story building. Preliminary studies show the south-facing living wall will be 25 percent cooler behind the wall than ambient temperatures," PNC said in a statement.

Currently, the wall is shades of green with darker green plants placed to create the bank's logo, but this spring some of the evergreen plants will bloom creating more color and changing the design.
