2.Wind Deflector Weight:-6.4 lbs <br /> 3.Module Gaps(ENV)=0.25 in <br /> 4.Wind Deflectors:Wind deflectors on the east and west edges of the array should overhang the east and west <br /> modules by six inches for Type 1 modules on the north rows only.Wind deflectors on the east and west edges <br /> of the array should overhang the east and west modules by six inches for Type II modules. <br /> 5.Bays:North row bays overhang the module by-6.5 inches and south row bays overhang the module by-12.25 <br /> inches. <br /> Testing <br /> 1.Coefficient of Friction <br /> 2.Wind Tunnel <br /> 3.UL 2703 <br /> 4.Component Testing(Bay and Clamp) <br /> Setbacks <br /> For the wind tunnel recommendations in U-Builder to apply,the following setbacks should be observed/followed <br /> for U-Builder wind design: <br /> 1.Modules should be placed a minimum of 3 feet from the edge of the building in any direction. <br /> 2.If the array is located near an obstruction that is 3.5 feet wide and 3.5 feet high or larger,the nearest <br /> module of the array must be located a distance from the obstruction that is greater than or equal to <br /> the height of the obstruction. <br /> 3.Installations within the setbacks listed above require site specific engineering.2 <br /> 4.The setbacks above are for wind.High seismic areas, fire access isles,mechanical equipment,etc., <br /> may require larger setbacks than listed above for wind. <br /> Site Specific Enaineerinq <br /> Conditions listed below are beyond the current capabilities of U-Builder.Site specific engineering is required. <br /> 1.Wind designs for a project design life exceeding 25 years1 <br /> 2.Building assumptions and design parameters outside of U-Builder assumptions <br /> 3.Attachments <br /> 4.Risk Category III or IV projects(U-Builder can be adjusted for the correct wind,but not the seismic or <br /> snow design) <br /> 5.Wind tunnel testing reduction factors are not permitted by the Authority Having Jurisdiction(AHJ)3 <br /> 6.Seismic designs that fall outside SEAOC PV1-2012 recommendations(>3%roof slope,or AHJ's that <br /> require shake table testing or non-linear site-specific response history analysis) <br /> 7.Signed and sealed site-specific calculations,layouts,and drawings <br /> Notes: <br /> 1.Please contact info@unirac.com. <br /> 2.Please contact EngineeringServices@unirac.com for more information. <br /> 3.Please contact Theresa Allen with PZSE Structural Engineers at theresa@pzse.com.These items <br /> will require direct coordination with PZSE to complete the requested services. <br /> g <br />
