A bit of Challenge

The project challenge was to create a blue-green roof on the primary roof of the new Kipling Bus Station. Stormwater tanks in or under the building were not deemed feasible due to the presence of the subway and other underground services as well as the general congested nature of the site. Under Toronto's Green Building Standard a portion of all stormwater needs to be captured and reused, and the rest has to be detained before being released into the storm sewer system. The design process was a collaborative process between Strasman Architects inc., the primary architect, NAK Design Strategies, the landscape consultants regarding the roofing and vegetated roofing options.

A design was created to capture as much of any storm as possible on the roof for both retention and detention. This was accomplished by using the LiveRoof Standard system on RoofBlue Risers. The combined stormwater management system covers 75% of the available roof space for a total of 4,270 sq m (45,900 sq ft).
