Project Address: TOMAS RODRIGUEZ RESIDENCE
196 NORTHEAST CAPRONA AVENUE,
PORT ST. LUCIE, FL 34983
Design Criteria:
- Applicable Codes = 2020 FLBC/FLEBC 7th Edition, 2020 FLRC 7th Edition, 2018 IEBC/IBC, ASCE 7-16 and 2018 NDS
- Risk Category = II
- Wind Speed = 158 mph, Exposure Category C, Partially/Fully Enclosed Method
- Ground Snow Load = 0 psf
- Roof 1-3 : 2 x 4 @ 24" OC, Roof DL = 7 psf, Roof LL/SL = 20 psf (Non-PV), Roof LL/SL = 0 psf (PV)
To Whom It May Concern,
Sincerely,
February 23, 2022
Based on this evaluation, I certify that the alteration to the existing structure by installation of the PV system meets the prescriptive
compliance requirements of the applicable existing building and/or new building provisions adopted/referenced above.
Additionally, the PV module assembly including attachment hardware has been reviewed to be in accordance with the manufacturer’s
specifications and to meet and/or exceed the requirements set forth by the referenced codes.
A structural evaluation of loading was conducted for the above address based on the design criteria listed above.
Existing roof structural framing has been reviewed for additional loading due to installation of PV Solar System on the roof. The structural
review applies to the sections of roof that is directly supporting the solar PV system.
