Results Summary, Assumptions & Conditions <br />Solar System Description <br />Client/Owner is planing to install rooftop solar arrays on the project site existing building(s). Summarized below <br />are the maximum loads that may be imposted on the subject structure based on Motive's review of available & <br />collected building data/information <br />Applicable Building Code Excerpts <br />Attachment Capacities (Not Required @ Fully Balasted Systems) <br />Insulation Pressure Capacity <br />Standard Foam insulation have a 16 psi minimum compressive strength. Refer to Polyiso <br />foam board ASTM C-1289. Compressive strength ranges from 16 to 25 psi. Therefore, <br />foam insulation is capable of supporting the said ballasted system. <br />Lateal loads resisted by an (E) member or an (E) LFRS may be increased by up to 10% <br />without a need to retrofit/assess the member or system. <br />Gravity loads resisted by an (E) member may be increased by up to 5% without a need to <br />retrofit/assess the member or system. <br />When solar panels/arrays are installed/positioned 24" or less above the surface of the <br />building roof or where proper signing restricting storage/access to below solar panels is <br />present, reporpusing the Live Load Capacity for solar Arrays is permissible. <br />Basis of Design Conditions & Assumptions <br />P- 9 <br />1901 N Fairview St & Bldg A, B, <br />C, F & 1919 N Fairview St Bldg E <br />4/11/2024
