TD Centre’s Living Roof

TD Bank wanted to go green when replacing the roof of its King & Bay bank pavilion in 2012. “The new vegetated living roof provides improved thermal resistance, reduces urban heat-island effect and limits stormwater run-off” (Green Reason). Additionally, the grid design preserves the existing roof pattern which is a protected element of the designated heritage building.

The grass planted on the TD Pavilion is low maintenance and grows within an aluminum structured grid. It is Creek Sedge Grass, which is a hardy, native plant. It’s very adaptive and is tolerant to the shade conditions of the TD Pavilion roof. 

The TD Living Roof retains and evaporates at least 50% of the rainwater that it receives annually. Green roofs in the City of Toronto serve as a treatment method, improving the quality of water that goes back into Lake Ontario, while also reducing the amount, by holding it and allowing it to evaporate.

An irrigation system was installed on the roof to ensure the grass receives enough water. The roof is not accessible for frequent visits so this system ensures the grass thrives while eliminating manual watering.
