Webinar description (Contact us for next presentation)

Vegetated or green roofs offer multiple benefits to urban areas. They manage stormwater, reduce energy demand, mitigate urban heat island, improve air quality and enhance biodiversity. The City of Toronto adopted the Green Roof Bylaw in 2010 and became the first city in North America to require green roofs on most new buildings, including high rise buildings and lakefront properties that experience high wind.

Wind flow around buildings creates both positive and negative pressure fluctuations across the roof, which affects both the roofing and the vegetated roofing systems. As part of the building envelope, it is important that that a vegetated roof is secured against these wind forces.

In this webinar, we will first take a look at CSA A123.24: Standard Test Method for the Wind Resistance of Modular Vegetated Roof Assembly and the 2 key test components to measure wind uplift and wind flow resistances. We will share case studies to demonstrate how vegetated roofing systems behave at different wind pressures and wind speeds with videos of the tests. Finally, we will illustrate how to use CSA A123.24 in the wind design process of vegetated roofing assemblies.

Learning Objectives:

  1. Define modular vegetated roof assembly (MVRA)
  2. Understand wind effects on roofing and vegetated systems
  3. Recognize governing factors of wind resistance for MVRA
  4. Test for wind uplift resistance and wind flow resistance
  5. Apply CSA A123.24 in wind design process for MVRA
