Description / Abstract:

This Standard specifies site wind speed classes for determining design wind speeds and wind loads for NCC buildings Classes 1 and 10 within the geometric limits given in Clause 1.2.

Wind loads for houses not complying with the geometric limits given in Clause 1.2 are outside the scope of this Standard.

2 A worked example for the determination of topography is given in Appendix B.

3 Worked examples for the determination of terrain category and shielding class are given in Appendix C.
