LiveRoof at the Canadian Green Building Festival

We have mentioned LiveRoof, the green roof for people with short attention spans before; it is the "prevegetated modular green roof system" that installs, complete, in hours rather than years. While visiting the Green Building Festival, I found that Terry McGlade of Gardens in the Sky is now growing them in the Toronto area. He explains in the video above why it is such a good technology; one interesting point was that because the roots are already grown into a tight mass, there is far less opportunity for wind and water to carry loose soil away and wash it into the drains.
