R Australian Wind Speed Regions Building wind loadings and debris impact loadings are determined by the regional wind speeds specified in the AS/NZS1170.2:2011 standard. The standard has four wind regions in Australia of which regions C and D are classified as cyclonic regions where protection from wind born debris is required. The building must be engineered to also withstand full negative internal pressure regardless of the glazing system used. Region D Cyclonic Area - The building envelope requires cyclone debris impact resistance between 34m/s and 44m/s. Region C Cyclonic Area - The building envelope requires cyclone debris impact resistance between 28m/s and 32m/s. Non-Cyclonic Area - Doesn’t require specific Cyclonic rated glass. Region A Non-Cyclonic Area - Doesn’t require specific Cyclonic rated glass.
