Design wind pressures and their applicable. This revision in zone designations was required because the values in zones around the roof in previous editions of the Standard were shown as having the same pressure coefficient, i.e., corners at the eave versus corners at the ridge have been found to have varying pressures. However, the roof still needs to be designed appropriately assuming the solar panels are removed or not present. Previously, designers commonly attempted to use a combination of the component and cladding provisions and other provisions in the Standard to determine these loads, often resulting in unconservative designs. Thus, these provisions are not applicable to open structures because the flow of the wind over the roof of enclosed structures and open structures varies significantly. However, Risk New Risk Category IV wind speed map New wind load criteria for rooftop solar panels Revised (higher) design wind pressures on roofs .

Also, a small revision was made to the hurricane wind speeds in the Northeast region of the country based upon updated hurricane models. Major revisions to ASCE 7-16 that affect the wind design of buildings have been highlighted. In some design review districts, an appointed board conducts design review using adopted design standards and guidelines. An updated study of the wind data from over 1,000 weather recording stations across the country was completed during this last cycle. 3 s peak gust, the ASCE 7 peak-gust map entails a decrease of the wind loads by a factor of (85/96)2 50.78.
