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 for <br />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 the height of the obstruction. <br />Exception: When using ASCE 7-16 Building Code and using the obstruction feature in the module editor to accurately model the size and <br />location of obstruction. <br />3. Installations within the setbacks listed above require site specific engineering <br />4. The setbacks above are for wind and seismic. Fire access isles, mechanical equipment etc., may require larger setbacks than listed <br />above. <br />Site Specific Engineering <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 years 1/ASCE 7-16 <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 snow design) <br />5. Wind tunnel testing reduction factors are not permitted by the Authority Having Jurisdiction (AHJ) <br />6. Seismic designs that fall outside SEAOC PV1-2012/ASCE 7-16 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 />7. Signed and sealed site-specific calculations, layouts, and drawings <br />8. Building that is not enclosed and categorized as open structures, carport or others <br />Notes: <br />1.
