Abstract
The National Research Council of Canada (NRCC), in collaboration with members of the Canadian roofing industry and vegetated system manufacturers, developed CAN I CSA A123.24, Standard Test Method for Wind Resistance of Modular Vegetated Roof Assembly, to evaluate the wind resistance of vegetated roof assemblies (VRAs). The existing literature (NRCA, 1 ANSI/SPRI-RP14 ,2 ANSI/ GRHC/SPRI VR-1, 3 FEMA P-757,4 FM 1-35,S) and Prevatf et. al 2012,6 provides only design guidelines and offers little to building officials to determine pass/fail criterial as a consensus standard will do.
