Wind-Roof Calculators on the Internet (Wind-RCI)

This web application determines wind loads for roof cladding and modular vegetated roof assembly design parameters based on the National Building Code of Canada 2020, subsection 4.1.7. The calculated loads are respectively used to determine resistance requirements in accordance with the CSA A123.21 and CSA A123.24 standards from the CSA Group.

This web application determines the climate severity for various Canadian locations listed in the National Building Code of Canada 2020 based on current and projected climatic data. It also determines the performance level for commercial roofs for climatic resilience requirements in accordance with the CSA A123.26 standard from the CSA Group.

This web application determines the resistance of the tested low-sloped membrane roofing specimens in accordance with the CSA A123.21 standard from the CSA Group.

This web application provides a common directory platform for tested systems in accordance with the "Standard Test Method for the Dynamic Wind Uplift Resistance of Membrane-Roofing Systems" (CSA A123.21).
