CSA A123.24 Standard Test Method (See video below)

The article examines the wind effects on modular vegetated roofing assemblies and explains how to use CSA A123.24-15 Standard Test Method for Wind Resistance of Modular Vegetated Roof Assembly to determine their resistance.

Vegetated Roof Assembly Wind Design Process: Three Simple Steps

The CSA A123.24-15 enables designers to determine if an assembly is secured against the wind uplift for a specific project by following three simple steps.  Read more about the wind design process the attached article.

Like any building envelope components, vegetated roof assemblies must be designed properly to resist wind forces to ensure durability and public safety. Designers should follow best practices from existing guidelines. CSA A123.24-15 provides a means to determine the wind resistance of modular vegetated roof system. Engineers should ask green roof suppliers for wind resistances of their systems and follow the wind design process to select the appropriate assembly for their projects.
