Canada is leading the way with the first standard test method for wind uplift for vegetated roof assemblies (VRAs). A research consortium led by wind expert Dr. Bas Baskaran of the National Research Council of Canada (NRC) is currently conducting wind uplift tests, and the results will be used to develop the first wind uplift standard of this kind. Simply put, it will be the “first systematic Pass/Fail technical standard for VRAs in the world,” says Dr. Baskaran.
The wind uplift tests are being conducted at the NRC’s Dynamic Roofing Facility in Ottawa, Canada, using a chamber fan mechanism that simulates the dynamic effects of wind. After laboratory testing, results will be benchmarked against real world conditions. “The next phase is to monitor vegetative cover on some actual buildings in the Greater Toronto Area under the influence of Mother Nature,” said Dr. Baskaran.
