Wind Zones



The building codes designate wind borne debris regions and the high velocity hurricane zone that require special consideration from architects and engineers. These areas are identified by the base wind speed map below*. In these areas, buildings must be designed to withstand high winds and damage from flying debris.


Table used to illustrate wind loads required for "typical" construction for various wind zones, exposure categories, and door sizes.

*Wind speeds are based on the American Society of Civil Engineers Standard (7-98) 50-100-year peak gusts.
