President - . Smart Vent Products, Inc. 430 Andbro Dr. Unit 1 . Pitman, NJ 08071. FROM:, Alexis Spyrou, P.E. . Building Drops, Inc... RE: . PRODUCT:NAME: 'FloodVent --;Impact Requirements Dear Mr. Graham; :The purpose of this:lettei-. is to evaluate the impact (wind-borne debris) :requirements for your FloodVENT.product, according to .the Florida Building Code (FBC) 2007 & 2010, International Building Code (IBC); International Residential Code (IRC), and ASCE 7 engineering standards. - Aceording:to the fBC Section :1626:1(e),all parts of the building envelope protectionshall meet impact test.criteria'except for vents in a garage with four or -fewer cars. The size of the vent is not to exceed the -minimum required design.area by'more than:25%. The typical FloodVENT opening size; .as indicated by the manufacturer, is 15.25" x 5' , or 0.53 square feet (sf). Typically two vents are installed per wall, which provides a total net open area , ' . of 1.06sf per installation. The total. net open:area.provided.by the vents. is regarded as insignificant such that the openings do not compromise the enclosure.category:of the structure. An enclosed building is one defined as not partially.enclosed and not.open. An o en building.is . defined as a building with each .wall being at least 80% open. A garage with flood,vents does not fall within the definition of an open building. A partially enclosed buildingis defined as.a building that complies.with both ofthe following:._ . 1.. The total area of openings in a wall that receives positive external pressure exceeds . the sum of the areas of openings in.the balance of -the building.envelope (walls and roof) by more than 10%. 2.. The total area of openings in a wall that receives positive external pressure exceeds 4 sf, or 1% of the area of that wall, whichever is smaller, and the percentage of . openings in the balance of the -building envelope does not .exceed 20 percent. g Pa e1of2 st. • PER9✓Iinlv , `uci C • e Count. �. . 127 W. Fairbanks Ave: . BUILDING DROPS Suite438. A fect Solution in Every Drop Winter.Park, FL 32789 Per Certificate of Authorization: 29578 . 407.644.6957 PH 407.644.2366 FX . contact@buildingdrops.com. A standard garage wall is approximately 25 feet long by 8 feet tall. This equals an .approximate wall area of 200 sf:. Thetypical net open area for two flood vents, as described above, is.1.06.sf, which is less.than 44 and .less than 1% of the wall area-. At can also be assumed that 1.06 sf does - not exceed more.than 10% ofthe.remaining open areas of the garage. Therefore, a garage.with flood vents cannot be considered a.partially enclosed building. . In my professional opinion, the flood vents manufactured by Smart Vent Products, Inc. do not . . require additional impact (wind -:borne debris) protection devices to be placed over them .so -that - they can continuefunctioning as flood vents. The vents do not increase the amount of openings in' a wall or. building such that the building classification changes from enclosed to partially enclosed... In addition, the 2010 FBC has specified applicable governing authorities to establish special: flood hazard areas as per FEMA specification under 2010 FBC section 1612.3. This. product has been. evaluated, dependent to specific site conditions, to meet the minimum requirements of the National Flood. Insurance Program (NFIP) flood'plain management requirements (44 CFR).with . respect.to flood openings for erclosed areas for the purpose of equalizing hydrostatic pressure resulting frorn flooding..The product has been evaluated to conform to design principles.noted in Section 2.6.2.2 of ASCE 24for a maximuni rate of rise and fall of 5.0 feet -per hour by the ICC-: ES under evaluation report ESR-2074.,Thus, the product.may be -used. in wall construction to .comply -.with 2010 FBC.Section 1612.5(1)(1.2), Please #eel free to contact me should you have any questions regardingthis evaluation. .
