The system will be tilt mounted on IronRidge rails. The system will be mounted directly to the plywood decking on the roof using the IronRidge Flat Roof Attachment.

Flat Roof Check Main Roof Loading: JoBNo. 2022-DS002 D.kTE Rev.4/6/22 CLIENT DS Energy BY R L-i sH=No. The roof was originally designed for a 20 psf roof live load. The distributed weight of the solar system with ballast is 2.7 psf on average. Therefore, using live load replacement, the roof structure overall is capable of carrying the loads. Roof structure can carry the distributed solar load based on live load replacement IronRidge Rails: Attachment to r)lvwood: Attach the IronRidge racking directly to the plywood deck using the IronRidge Flat Roof Attachment (see Appendix B). This attachment is a 7" diameter circle. Check bearing on plywood: The capacity of /" plywood (4 ply) per NDS Table M9.2-4 is: 81 Win of shear resisting panel length. The length in shear is the circumference of the attachment: L = 3.14(7") = 22" The shear capacity of the plywood at the attachment is: Va = (81 Ib/in)(L) = 1782 Ibs The worst case loading on an attachment is 260 Ibs Plywood is okay to carry point load. Check screw connection to plywood: Max uplift force = -202 Ibs A#15 screw in '/" plywood has the following capacities according the APA E830E report (see Appendix B). Va = 590 Ibs / 3 F.S. = 197 Ibs Ta = 350 Ibs / 3 F.S. = 117 Ibs Attach Flat Roof Attachment to roof deck using a minimum of 4415 screws 11Page rs" /� P LIED.

JOBNo. 2022-DS002 DnrE Rev 4/6/22 CLIENT DS Energy ur RHA slicer No. Plywood Check - The loads from the solar have been moved around on the plywood to create the absolute worst case moment and shear in the plywood. Downward Condition: P = 191 lbs. This point load will act as a uniform distributed load under the 7" attachment: w = P/7" = 327 plf See A1. M = 0.049 k-ft = 588 in-lbs, V = 247lbs. Upward Condition: P = -202 lbs, w = -346 plf See A1.1. M = 0.043 k-ft = 516 in-lbs, V = 133 lbs. For the purposes of this plan check, we shall pretend that only a 12" wide strip of the plywood resists this load. Obviously, this is grossly inaccurate, but is conservative. Per Table M9.2-1 of the NDS, the bending capacity of 4 ply CDX is 405 in-Ibs/ft of width: Ma = (405 in-Ibs/ft)(1')(1.6 Cd) = 648 in-lbs. Per Table M9.2-4 of the NDS, the shear capacity of 4 ply CDX is 81 lb/in: Va = (81 lbs / in)(12")(1.6 Cd) = 1555 lbs Plywood is okay to carry solar point loading Check Plywood Connection to Joists - The plywood is nailed to the roof joists using at minimum 6d nails at 12" oc in the field. The worst -case reaction from Al.1 is -98 lbs (ASD). Per NDS Table 12.2C, the withdrawal capacity of a 8d nail in wood having a specific gravity of 0.5 is 33 lbs/in. The top chord of the 1-joists is 1.5" thick and there is a 1.6 load duration for wind loading. This yields an allowable per nail withdrawal load of: Ta,nail = 1.6 x 1.5" x 33 p/in = 79.2 lbs There are nails at least every 12" oc to the joist. Assuming two nails resist the uplift load. This gives a capacity as follows: Ta = 158 lbs The plywood nailing is capable of transferring the uplift loading. Please note that since ASCE7 allows for neglect of uplift C&C wind on the plywood deck where covered with panels and since C&C loads were still included on the deck in Al.1, this answer is EXTREMELY CONSERVATIVE. Check of Screws to Carry Lateral Loading Even though the screws pass thru a '/" layer of fiberboard that underlays the entire roof (and provides a huge amount of shear resistance), we shall check the screws here as if they were actually freestanding 21Page M P P L' E a Jon ISTWANS a �:�nkaa�+scniwrr CanmuixaNre, kNC. Jon No. 2022-DS002 nATE Rev.4/6/22 is CUENrc DS Energy BY RHA sHEETNo. (no support from the fiberboard or foam). This is not a realistic model of the actual field conditions, but will provide an overly conservative check of the design. Please notice that the panels are now laying flat, unlike in the original submittal. The IronRidge report in Appendix B now reports the shear reaction as 0 lbs. We shall still check the attachment for the original 54 Ibs of wind shear from the 10-degree tilt design. We shall also check the screws for the seismic load per ASCE7 Equation 13.3-1: Fp = Omega x 0.4(ao)(Sds)(Wo)(1+2z/h) = 45.8 Ibs Rp/lp Rp = 1.5, Ip = 1.0, z/h = 1, ap = 1, Omega = 2, Wp = weight per attachment (IronRidge report) = 26.4 Ibs The screws are placed at a 30-degree angle in the attachment and they pass through 6" of foam. These have been modeled in RISA-31D. Joist Check: The 1-joists roof framing were designed to carry 20 psf of live load and the solar system only weighs 2.7 psf. Furthermore, the Legacy report for the 11-7/8" TJI/Pro 250 joists shows that they can span 21'-5" at 16" oc and carry 20 D + 20 L psf. These joists only span 19'-6" and carry a roof dead load of 14 psf, including their own self weight. Joists are OK by inspection. Ponding Check: The dead load point loads on each attachment are only 26.4 Ibs. Ponding analysis is not necessary by inspection. Lateral Building Check: Wind profile of the building is unchanged by the addition of the solar system. Seismic Weights: Roof = (2500 sf)(14 psf) = 35 kips Allowable solar = (Wroof)(10%) = 3.5 kips Solar = 1.95 kips < Allowable solar Lateral System OK under Existing Building Code section 403.4 3 1 P a g e Appendix A: Computer Calculations Project Title: Engineer: Project ID: Project Descr: DESCRIPTION: Al - roof deck for bending, downward General Beam Properties Elastic Modulus 1,500.0 ksi Span #1 Span Length = 1.330 ft Area = 24.0 inA2 Moment of Inertia = 0.50 inA4 Span #2 Span Length = 1.330 ft Area = 24.0 inA2 Moment of Inertia = 0.50 inA4 Span #3 Span Length = 1.330 ft Area = 24.0 inA2 Moment of Inertia = 0.50 inA4 Span #4 Span Length = 1.330 ft Area = 24.0 inA2 Moment of Inertia = 0.50 inA4 Span = 1.330 ft I Span = 1.330 ft i Span = 1.330 ft Span = 1.330 ft Applied Loads Service loads entered.

Users should confirm any output obtained from this toot with the local Authority Having Jurisdiction before proceeding with design. Hazard loads are interpolated from data provided in ASCE 7 and rounded up to the nearest whole integer. Per ASCE 7, islands and coastal areas outside the last contour should use the last wind speed contour of the coastal area — in some cases, this website will extrapolate past the last wind speed contour and therefore, provide a wind speed that is slightly higher. NOTE: For queries near wind-borne debris region boundaries, the resulting determination is sensitive to rounding which may affect whether or not it is considered to be within a wind-borne debris region. Mountainous terrain, gorges, ocean promontories, and special wind regions shall be examined for unusual wind conditions.

For maxi- mum strength and stability, each joint requires a design adapted to the fastener type and to the strength properties of the individual structural members. Included in the following tables are ultimate withdrawal and lateral loads for ply- wood joints fastened with wood and sheet metal screws. These values are based upon tests conducted on plywood by APA — The Engineered Wood Association. To calculate design withdrawal and lateral capacities for various sizes of wood screws, see Table 11.3.1A of AF&PA NDS-2005, and APA Technical Topic TT-051 and Section 4.4.7 of Panel Design Specification, APA Form D510. See also www.awc.org/calculators/fndex.html for online fastener calculators. TEST RESULTS Panel -and -Metal. Connections Self -drilling, self -tapping screws are commonly used to attach panels tip to 1-1/8 inches thick to steel flanges up to 3/16 inch thick. However, since threads are usually provided on only a portion of the fastener shank, it is important to specify the appropriate fastener length for a given panel thickness. This precaution ensures that the threaded por- tion of the shank will engage in the steel framing. Several lengths and styles are available. Additional details for these types of screws may be obtained from specific fastener manufacturers. The following test data apply to wood screws and sheet metal screws. Little design data is available on sheet metal screws, but the primary difference between wood and sheet metal screws is that sheet metal screws are generally threaded their full length and wood screws are only threaded about two-thirds of their length. Lateral Resistance: Performance of panel -and -metal connections is dependent upon the strength properties of all three elements. a) Panel -critical joints are characterized by a shearing of the wood fibers oriented parallel to the direction of the applied force. b) Fastener -critical joints are characterized by a shear failure of the screw shank. As shown in Figure 1, once localized crushing of the wood has occurred, resistance of the metal to fastener -head embedment causes the screw to become FIGURE I FAILURE OF LATERALLY LOADED, SINGLE. SHEAR .METAL -TO -PLYWOOD CONNECTION eJ I®� s'!W�1.Allr Crushing of plywood a shear specimen and joint behavior is dependent upon the shear strengthof the fastener. Shear failure of the screw shank occurs at the wood -metal interface. 0 The metal -critical joint may fail in one of two ways. Failure occurs when the resistance of the screw head to embedment is greater than the resistance of the metal to lateral and/ or withdrawal load, and the screw tears through or away from the metal. Failure also occurs when thin metal in a metal -to -panel joint crushes or tears away from the screw. The following test data are pre- sented for plywood only. Tables l and 2 present average ultimate lateral loads for wood - and sheet -metal -screw connec- tions in plywood -and -metal joints. The end distance of the loaded -edge in these tests was one inch. Plywood face grain was parallel to the load since this direction yields the lowest lat- eral loads when the joint is ply- wood -critical. All wood -screw specimens were tested with a 3/16-inch-thick steel side plate, and values should be modified if thinner steel is used. TABLE 1 ''.. SCREWS: METAL -TO -PLYWOOD CONNECTIONSM !

Loads denoted by an asterisk(*) were limited by screw-to4ram- ing strength; others were limited by plywood strength. u Withdrawal: Tables 3 and 4 present average ultimate withdrawal loads for wood and sheet metal screws in plywood -and -metal joints, based on analysis of test results. Wood screws are threaded for only 2/3 of their length. Sheet metal screws typically have higher ultimate load than wood screws in the smaller gages because of their full-length thread. Values shown in Table 3 for wood screws are based on 1/4- inch protrusion of the wood screw from the back of the panel. This was to assure measurable length of thread embedment in the wood, since the tip of the tapered wood screw may be smaller than the pilot hole. This was not a factor for sheet metal screws due to their uniform shank diameters.

Tl Proieet Description: Client is installing two Fortress 18.5 kWh battery storage systems at this site. The batteries will be installed inside; therefore, there will be no wind loading on them. The Fortress units are secured at their top only and the bottoms sit on the slab with rubber feet. The anchors at the top will resist any overturning. The coefficient of static friction for rubber feet on dry concrete ranges from 0.6 to 0.85 (use 0.6). Building Codes Used: 2019 CBC / 2018 IBC, ASCE 7-16, ACI 318-14 Wind Loading: NO WIND (mounted indoors) Seismic Loading: Ip = 1.0 Design Category D, ap = 1, Rp = 2.5, 0 = 2 Site: Sds = 1.095 OUTDOOR GROUND MOUNTED EQUIPMENT Battery Storage Container & PCS EQUIPMENT PROPERTIES Weight(Wp) :..:..._.,,520ilb Width(W)- 20in Depth(D) =2Qin Min. distance, bolt to opposite face (N) .. 20!.. in Min. distance, center of gravity (D') - „'., 10'. in Height(H) v -42i in H, (Assume COG at 2/3 H)= «m H/D = 2.08 Anchor brackets (n) 4`7 WIND DEMANDS PER ASCE 7-10 V=111A Wmph K, K„ L Ka oi9' qz=0.00256K,K„KaVz 0.0 psf G .._?_t....._�.85.1 Cr = 1.32 Fw = q,GCfWH/144 = 0 lb SEISMIC DEMANDS PER ASCE 7-10 Sos= 9 ap= 11 RP= 25 z/h- ujQOi Fpi, = 0.4apSosWp(1+2z/h)/(Rp/lp) = Fph,n, . = 1.6*Sos*Ip* Wp = Fph,.[m = 0.3*Sos*lp* Wp = Fph,,pMrdlmg = LOAD RESISTANCE Check friction at base: Determine force at top to resist overturnine: OTM RM Force in screws to resist net moment (with R) Assuming 1/2 lateral load goes to screws 91 lb 911 It, 171 lb 171 lb 312 Ibs Figure 26.5-1A Table 26.10-1; Exposure C, h < 15 ft Section 26.8.2 Table 26.6-1 Equation 29.3-1 Section 26.9.1 Figure 29.4-1 Equation 29.3-1 Design Short Acceleration per Equation 11.4.3 Component Amplification Factor per Table 13.6-1 Component Response Modification Factor per Table 13.6-1 Ground -Mounted Importance Factor per Section 13.1.3 Omega Factor per Table 13.6-1 Equation 13.3-1 Equation 13.3-2 Equation 13.3-3 The base friction is greater than the entire seismic lateral load. 400 ft-Ibs 396 ft-Ibs 3 Ibs Unfactored load 62 Ibs ASD level load (this includes the load from overturning) Run 1 horizontal P1000 Unistrut behind both batteries.
