| | 1. PROVIDE A ROOF DIAGRAM SHOWING PROPOSED LOCATION AND |
| | EXISTING ROOF PITCH. FBC R301. THE ENGINEERING PROVIDED |
| | STATES THAT THE INSTALLATION COMPLIES BUT SPECIFIC |
| | INFORMATION REGARDING LOCATION (REQUIRED TO DETERMINE |
| | DESIGN PRESSURE) WAS NOT PROVIDED IN THE PLANS. |
| | |
| | 2. PLEASE CLARIFY; S2 STATES THAT THIS INSTALLATION IS |
| | FOR A ROOF SUBJECTED TO MAXIMUM PRESSURE OF 67PSF. S3 |
| | INCLUDES A TABLE WHICH PROVIDES ROOF PRESSURES FOR |
| | COMPONENTS & CLADDING FOR 20SF AND 50SF OF EFFECTIVE |
| | WIND AREA. IT IS NOT CLEAR WHETHER THIS DESIGN CRITERIA |
| | APPLIES TO THE WIND RESISTANCE OF THE SOLAR PANEL |
| | ITSELF OR UPLIFT PRESSURE ON THE FASTENER. WOULDN'T |
| | EACH FASTENER HAVE AN EFFECTIVE WIND AREA OF LESS THAN |
| | 10SF (40SF TOTAL SF, DIVIDED BY FOUR FASTENERS)? SEE |
| | FBC1609.2, DEFINITION OF EFFECTIVE WIND AREA. IT |
| | APPEARS THAT THE DESIGN CRITERIA WIND PRESSURES REGARD |
| | THE SOLAR PANEL AREA AS A BUILDING COMPONENT (LIKE A |
| | WINDOW OR DOOR) RATHER THAN TREATING IT AS CLADDING, |
| | AREA TRIBUTARY TO EACH FASTENER (SUCH AS ROOF OR SIDING |
| | CLADDING). IT APPEARS THAT FOR EACH INSTALLATION THE |
| | WORST CASE (DESIGN PRESSURES ON FASTENER RATHER THAN ON |
| | THE PANEL) WOULD GOVERN, BUT 10SF (WHICH WOULD APPLY TO |
| | THIS JOB) PRESSURES WERE NOT PROVIDED. PLEASE EITHER |
| | CLARIFY WIND RESISTANCE STATEMENT (THAT BOTH PANEL AND |
| | FASTENER HAS BEEN ADDRESSED IN DETERMING THAT THE |
| | INSTALLATION IS COMPLIANT FOR -67PSF) AND INCLUDE 10SF |
| | EFFECTIVE WIND AREA ON THE CHART, OR PROVIDE RATIONALE |
| | FOR USING COMPONENT DESIGN PRESSURE FOR FASTENERS. |
