Personally, i don't understand how they can push this as a green roof.
Being built green means be built environmentally friendly, through design, construction and sustainabiliy.
The only way this has any environmental impact the fact that is uses some of the rain water instead of it being run off in the sewer system.
That being said, this roof is no more green than the average roof in regards to the building envelope. Meaning things like heating and air/water
It is neat though, lawn on your roof.
