OTTAWA — Canada is leading the way in improving the quality of green roofs with the first standard test method for wind uplift for vegetated roof assemblies (VRAs).
The new testing has been pushed forward by Xeroflor, inventor of the pre-grown vegetated mat, as well as a research consortium led by National Research Council of Canada (NRC) wind expert Das Baskaran.
Baskaran says it will be the world’s first system implementing a pass/fail tenchnical standard for VRAs.
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 lab testing, the results are 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 Baskaran.
