Vertical Green Walls by Patrick Blanc

Patrick Blanc is one of the most high-profile pioneers in the fantastic world of green walls. These vertical gardens are beginning to proliferate across Europe and it won't be long before we see them across major US cities.

Proponents argue that by infusing an exterior wall with a living organism such as plants the ambient temperature of the structure and it's surrounding areas goes down which in turn draws down the amount of energy needed to heat or cool. Unlike vines which are set to just keep growing, these vertical gardens are highly engineered from placement to irrigation which typically comes from rainwater storage.
