Note: The publication dates listed below don't necessarily reflect the publication dates of the data therein. The International Building Code (IBC) is published by the International Code Council and references ASCE/SEI 7 for its wind load provisions. But the process of taking those values and creating design wind load values is dependent on a lot of other factors that are site and design specific, and those are clarified in the structural commentaries. For example: If you were looking to install a small wind turbine, you would reference the 30 m map for your location.A project placed in an area that is orange colored (12.3-14.5 mph expected wind speed) would be predicted to perform better than a turbine placed in a location that is not colored (less than 10 mph).
