Green Walls / Living Walls

Im posting this simply to educate the audience on the concept of "Green Walls".......Green Walls according to Green Roofs for Healthy Cities (GRHC, www.greenroofs.org) can be categorized into 2 areas, Green Facades and Living Walls. In simplicity Green Facades are a structural based system such as a modular trellis or cable system to include a soil base with climbing plant material. Living Walls are a growing media based system from top to bottom that is retained within a modular unit. Thirdly there are the systems, such as a Patrick Blanc that are a non media based system but do require a consistent flow of irrigation. In addition there is also the Bio-Wall that was designed to allow air to pass through and redistributed to various parts of the building.....If you are interested in the various systems you can view the Greenwalls 101 course offered by GRHC.....
