KIPLING TRANSIT HUB BUS TERMINAL

The Kipling Transit Hub is an important transit facility in Toronto's west end, in Etobicoke. It connects the western terminus of the Toronto Transit Commission subway Line 2 (Bloor -Danforth), the TTC west end bus system, the Milton Line of the GO Transit commuter train system and now Mississauga's MiWay Bus system.

The transit hub is in the middle of a very rapidly developing transit dependent neighborhood with at least 5 highrise complexes and a number of midrise developments recently completed, under construction of in planning.

Date of the project: Project started in 2020 for about 1 year duration

Project Location: Etobicoke, Ontario

Project Size: 49,000 sq.ft

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). 

The roofing system selected to protect the building is a conventional Sarnafil G410 white PVC system with R-35 insulation value. This system was selected for its proven performance and the recyced content in the PVC membrane.
