Setbacks <br />For the wind tunnel recommendations in U-Builder to apply, the following setbacks should be observed/followed for <br />U-Builder wind design: <br />1. Modules should be placed a minimum of 3.00 ft from the edge of the building in any direction. <br />2. If the array is located near an obstruction that is 3.50 ft wide and 3.50 ft 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 the height of the obstruction. Exception: When <br />using ASCE 7-16/ASCE 7-22 Building Code and using the obstruction feature in the module editor to accurately model the size and location of <br />obstruction. <br />3. Installations within the setbacks listed above require site specific engineering <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 Engineering <br />Conditions listed below are beyond the current capabilities of U-Builder. Site specific engineering is required. <br />1. Building assumptions and design parameters outside of U-Builder assumptions <br />2. Risk Category IV projects <br />3. Wind tunnel testing reduction factors are not permitted by the Authority Having Jurisdiction (AHJ) <br />4. Seismic designs that fall outside SEAOC PV1-2012/ASCE 7-16/ASCE 7-22 SECTION 13.6.12 recommendations (>3% roof slope, or AHJ’s that <br />require shake table testing or non-linear site-specific response history analysis) <br />5. Signed and sealed site-specific calculations, layouts, and drawings <br />6. Building that is not enclosed and categorized as open structures, carport or others <br />Notes: <br />Please contact EngineeringServices@unirac.com for more information. <br />Page 43 of 43
