Vreeland Design Associates Re: Kirley/Leighton Solar Project, 123 Meadow St, Florence, MA: Structural assessment of existing barn roof to support proposed solar array. I have investigated the roof framing in the area of the proposed PV solar panel installation. The 26'x 54' barn is a 5-bent,4-bay structure with an average bent spacing of 13'-6". The rafters are full dimension 3x5 installed at 26"on-center, spanning 13'-0", and supported at the mid-point by 7x7 purlin beams. The timber frame bents are made up of three (3) 7x7 posts, 7x7 tie beam,two 6x6 vertical purlin posts supported on the 7x7 tie beam,with the bents tied together with 7x7 cave and purlin beams. 3x4 diagonal bracing is installed between most of the posts and beams.The barn is supported on an 8" concrete frost wall. The second bent in Sum the west, the 7x7 tie beam has been replaced with a W 12x30 I-beam. The third bent in from the west has a 2x4 stud wall framed in under the tie beam and up to the roof. The third bay in from the west has a loft floor framed in 2'-9"below the tie beam. The roof slope is approximately 8/12. A corrugated metal roof has been installed. 42 solar panels are proposed on the south roof of the barn over three(3)bays starting from the west gable end. Based on my calculations all the framing is adequate to support the proposed solar panel and current snow load requirements except for the 4th bent in from the west gable end which corresponds to the eastern edge of the solar array. The section of the tie beam under the south roof will need to be reinforced by one of the following options: I) Sister 1'/4"x 7'/"x 12'±LVL to both sides of the tie beam, attached with 2—5" LedgerLok screws at 12"on-center or 2) Sister C4x5.4 steel channel by 12't (the channel is 4"tall by 1- 5/8"wide)to both sides of the tie beam, attached with "/2"x3"lag bolts at 16"on-center. Locate the bottom of the steel channel 1"up from the bottom of the tie beam and drill the holes in the center of the channel. I have reviewed the mounting details for the proposed array. Based on a PV solar panel unit weight of 42+ lbs, with the attachment points of the array placed at a maximum of 4'-4" on center and staggered to minimize the load to any one rafter,the existing roof framing,with the reinforced tie beam as outlined above, is adequate to support the proposed PV solar array and the snow and wind load requirements of the current MA State Building Code. Please contact me if you have any questions or need additional information.

Taggart, Vice President Products Subject: IronRidge XR100 Rail, Roof Flush Mounting System —Structural Analysis Dear Sir: We have analyzed the IronRidge XR100 Rail for the subject solar module support system and determined that, for the configurations and criteria described below, it is in compliance with the applicable sections of the following Reference Documents: Codes: ASCE/SEI 7-10 Min. Design Loads for Buildings& Other Structures International Building Code 2012 Edition Other: AC428,Acceptance Criteria for Modular Framing Systems Used to Support PV Modules, dated Effective November 1,2012 by ICC-ES Aluminum Design Manual, 2010 Edition The IronRidge XR100 Rail is an extruded aluminum section with an overall depth of 2.438 in. and a net area of 0.583 sq.in. The rails are used to support solar modules, typically, on the roof of a building. See Exhibit A—attached. The rails are clamped to aluminum angle brackets that are either attached directly to the roof framing or attached to a stand that is screwed to the roof framing. The rails are mounted across the slope with a small clearance (flush mounting) to the underlying roof structure. The installed solar modules are at the same slope as the underlying roof structure. All loads are transferred to the roof framing through the angle brackets by simple bi-axial flexure of the rails. The maximum span of the rails is governed by either the mid-span flexural stresses or the deflection requirement that the rail not come into contact with the roof. The effect of seismic loads (for all design categories A-F) have been determined to be less than the effect due to wind loads in all load conditions and combinations. Therefore, the maximum allowable spans for common load cases are shown in the tables below. Tables 1A-9A are for modules with a maximum long dimension of 67.5 inches and Tables IB-9B are for modules with a maximum long dimension of 78.5 inches. Starling Madison Lofquist, Inc. Consulting Structural and Forensic Engineers IronRidge December 18, 2014 Mr. David F. Taggart Page 20 of 20 IronRidge XR100 Rail, Roof Flush Mounting System—Structural Analysis Notes—Tabulated values are based on the following criteria: 1. Building mean roof height=30 ft 2. Risk Category I 3. Solar maximum module long dimension is 67.5 inches for Tables 1A-9A and 78.5 inches for Tables 1B-9B. 4. Provide 2 in. clear between roof and rail 5. End cantilever span (max) = 0.40 x maximum span from above tables 6. No rail splices in end spans 7. No rail splices in middle 1/3 of interior spans 8. Single simple span(s). Spans listed in the tables above may be multiplied by 1.08 for continuous rails of 3 or more spans. Our analysis assumes that the rails, including the connections and associated hardware, are installed in a workmanlike manner in accordance with the "hronRidge Roof Mount Installation Manual" by IronRidge and generally accepted standards of construction practice. Additional information is available at the IronRidge web site, IronRidge.com. Verification of PV Module capacity to support the loads associated with the given array shall be the responsibility of the Contractor or Owner and not IronRidge or Starling Madison Lofquist. The adequacy of the supporting roof framing is to be determined by others. Please feel free to contact me at your convenience if you have any questions.
