This Standard sets out data and procedures for determining design wind speeds and wind loads for housing only. Wind speeds are specified for the serviceability and ultimate strength/stability limit states, and for permissible stress design. Where houses do not comply with the limitations of this Standard, AS 1170.2 should be used.

This Standard sets out data and procedures for determining design wind speeds and wind loads for housing.Alternatively, design wind speeds and wind loads for housing may be obtained using AS 1170.2.
