Living Wall (Green Wall) at Musée du quai Branly - Jacques Chirac in Paris

I look forward to the day building owners, code officials, architects and engineers work to incorporate green walls to exterior building facades. This was the first green wall I've seen in person, and it was inspiring. The fresh cool air emitting off the wall was akin to walking through the lush jungles of Kauai (seriously!). Can you imagine walking through Manhattan with buildings covered in greenery, filtering and cooling the air?
