The solar designer, REC Solar (REC) has hired Engineered Power Solutions (EPS) to address the structural aspects of this project, mainly the design of the PV racking system, the required ballast weight, and the structural adequacy of the anchorage to the existing structure. EPS has been informed that the ability of the existing structure to support the additional design loads imposed by the proposed roof mounted system is by others (refer to the "Scope of Work" section below for further clarification).

This includes roof dead load, roof live load, wind loads, snow loads, seismic loads, etc. o Determination of the Series 450 wind forces based on the site specific wind loads, the geometry of the building, and the requirements given by the wind tunnel testing report (provided by REC) for the Series 450 racking system. o Determination of the number of required positive attachment points and their locations based on the site specific wind and seismic requirements. o Calculations and structural details (if required) showing the adequacy of the anchorage of the positive attachment points to the existing roof. *Approval of the existing building's ability to structurally support the new design loads imposed by the new PV system is not included in this scope of work. This is to be approved by others.

EPS must be immediately notified in writing if existing as-built roofing conditions differ in any way from the information provided by REC and/or described in this packet. Any changes to the installation requirements given in REC's plans must be approved in writing by EPS prior to implementation. All non-structural issues including but not limited to waterproofing, corrosion protection, electrical, and mechanical issues are not the responsibility of EPS and must be addressed by the solar designer, installer, and/or owner before PV installation begins. Approval of the existing building's ability to structurally support the new design loads imposed by the new PV system is by others.

Therefore, the wind loads imposed on this PV system have been determined in accordance with Section 6.6: Method 3 —Wind Tunnel Procedure of ASCE 7-05. The wind tunnel testing consultant has issued a report to REC documenting their results. REC as provided that report to EPS with the purpose of determining the wind loads on each PV module. REC can submit the complete wind tunnel testing report to the Governing Building Jurisdiction or Building Official upon request. The following pages document the determination of the wind forces on the PV modules using the wind tunnel testing results with the purpose of specifying the ballast weight required to resist the maximum code prescribed wind uplift forces. If the wind uplift forces exceed the amount of ballast weight that can be added to a module (due to space limitation or the building's capacity to support the additional weight) then a positive attachment is required at that location as detailed in REC's plans and described within this packet.

These roof zones are described as follows: o Zone A—North Corners o Zone B —Secondary North Corners o Zone C —Tertiary North Corners o Zone D —Middle of Roof o Zone E —Secondary South Edges o Zone F —South Corners o Zone G—Transition Region between D & E for South Rows o Zone H—The South Row of an array affected by corner vortices The size of each zone is determined by the building height.

See Figure 6 below.

Edge rows of arrays were also assigned unique pressure coefficients.

As stated in the wind tunnel testing report, "[ilf the system shares loads in the north-south direction... further wind load reductions are warranted because of the loss of correlation in the flow patterns causing the wind loads." For each module (more than one) connected to another in the north-south direction, a reduction of the wind loads of 5% is warranted up to 40% at 10 modules or more. It is also stated that for "modules within 5 parapet heights of the edge, reduce any value by multiplying by 0.5."

The rear wind deflector can hold a maximum of 5 pavers. If more than 5 pavers are required, additional ballast trays can be added under the module assembly (maximum of 2 additional trays) which can each hold an additional 5 pavers (maximum of 15 pavers). Per the required load combination 0.6D+W, only 60% of the module assembly and ballast pavers have been taken into account to resist the calculated wind uplift forces. If more than 15 pavers are required, a standoff (positive attachment to the roof) is required under that module. The details below show a typical module and paver assembly.

The modules shaded red require no ballast blocks as they share rails with the standoff so that the uplift force would be transferred to the standoff.

Locations with standoffs will only show the weight of the module assembly since the uplift forces are resisted by a positive attachment to the roof. A standoff connects to east-west running rails that span to the north-south running rails which link modules together. Therefore, a standoff provides uplift support for the module it is under as well as the module on either side of it (east-west direction). 151 141 141 141 141 1 41 1 41 151 76 66 56 141 141 55 66 76 151 141 1 41 55 56 141 141 151 76 55 55 141 141 55 66 7.6 151 115 116 116 116 115 116 151 Figure 13:Actual(Supplied)Weight per Module (lbs.)

A negative value (colored green) represents ballast weight greater than what is required at that module. A positive value (red) represents a net uplift weight force on that module. The yellow modules represent standoff locations with their corresponding positive uplift value to be resisted by the standoff. It is acceptable to have a net uplift on single module as long as the net ballast weight of that array block is greater than the calculated net uplift force on that array block and no north or south row, nor edge modules have a net uplift. The maximum net uplift cannot be greater than the weight of one paver (25 lbs.) for modules that are not adjacent to a module with a standoff. The proposed baseplate uses (6) 5/16" diameter lag screws into the existing 1/2" plywood roof sheathing. This provides a wind uplift capacity per the 2005 NDS of 984 lbs. but the strength of the standoff rails limits this uplift capacity of 800 lbs. per standoff. The following layout limits the uplift force to less than 800 lbs. as required as the highest uplift load is 118 lbs. -7 -10 -10 -15 -15 -10 -10 -7 38 _ 40 -5 -5 40 - 38 -7 -5 -5 40 -- -5 -5 -7 38 40 -5 -5 40 38 -7 -5 -5 -5 -5 -5 -5 -7 Figure 14: Net Uplift Forces per Module (lbs.)

The seismic demand on the PV system has been calculated per Section 13.3.1 using the equation below: o Fp = [(0.4*ap*SDs*Wp) /(Rp/Ip)] * (1 + 2(z/h)) • Where Fp is not greater than Fp = 1.6*SDS*Ip*Wp and • Fp is not less than Fp = 0.3*SDs*Ip*Wp Using the site specific spectral accelerations (see following page for USGS Website Printout), the SDS was determined to be 0.706. This produced an Fp of 0.339*Wp where Wp is the total weight of each array. Per the load combinations given in the governing code, the allowable level (ASD) seismic design force would be 0.7*0.339*Wp 4 0.238*Wp. Using the total weights of each array (given in Table 5) and the maximum shear resistance of a standoff, the required number of positive attachment points (standoffs) per array was calculated: Overturning resistance was determined to be 253 lbs. based on the geometry of the baseplate and the NDS withdrawal design values (Table 11.2A). Per the array labels shown in Figure 15: o Array 1: (4,552 lbs. * 0.238) /253 lbs. = 4.3 4 5 Standoffs Min.
