Design With Wind in Mind

Building dimensions: It is easier and less expensive to satisfy the target wind load if the house falls within some design and dimension guidelines. Designing to fit these parameters may also make it possible to comply with one of the prescriptive wind standards (and not have to hire an engineer to calculate loads and specify details) or a code-plus certification program such as Fortified…for safer living.

In general, the simpler the house design, the less it will take to meet the desired wind resistance. It is recommended that the house be no more than 60 feet long, and the length not more than twice the width. The house should have no more than two stories, and the ceiling (wall height) of each story should not be more than 10 feet high.

If the home does not meet these criteria, it can still be considered for a Fortified…for safer living designation if a registered professional engineer or architect certifies that the structure was designed for wind loads corresponding to the wind design speed required for certification (At this time, the program requires 130 mph or higher, but criteria could change in the future.)
