Perhaps it might be possible here in Calgary too.
Green roofs would be un-green in Calgary as they would require massive amounts of irrigations. The SMART Technologies building in the NW was originally planned to have a green roof but that was changed after it was determined that massive amounts of energy and water would be required to keep the very exposed greenery alive in Calgary's climate.
