This certification follows the design requirerr "Openings in Foundation Walls and Wails of Enclosures Be Standard for °Flood Resistant Design and Construction` (ASC and certified by Mr. Christopher Mark Loney, Virginia PE N 'Review of certifeation of Engineered Flood Openings, dated of Building Construction, Virginia Tech. Characteristics MA TB 1.08, and ASCE/SEI 24-05 s 816CS,1220C5,123$CS,1616CS,1624CS.1632CS, 2032CS, 2424CS, of the NFIP "Flood Insurance Manual' (2011) to provide automatic try and exit of floodwpters, when properly installed and sized as set its and specifications established in FEMA Technical Bulletin 1-08, v Elev^ted Buildings In Special Flood Hazard Areas", and the ASCE iE124-05). The actual vent opening measurements were determined 029000. Calculations are based on the spreadsheet formulas, and nuary 16, 2012" prepared by Dr. Georg Reichard, Associate Professor Section 2.6.2.2 of ASCE 24 provides an equation to determine the required net area of engineered openings (A) for a given enclosed area (A.). This equation is based on the hydraulic formula for the flow rate across sharp edged orifices. I have utilized this equation to calculate 1) the respected flow rate through the individual openings between louvers; 2) the flow rate through the main frame opening in case the louver Is blown out during a flood event; and 3) the flow rate of water flowing through louver blades following hydrauric short tube theory. The ultimate maximum total enclosed area (A.) that can be serviced by a single vent has then been determined by utilizing the lowest low rate of the three assessed scenarios for each vent and is listed In Table 1. These values are based on the following assumptions: • In absence of reliable data, the rates of rise and fall have been assumed with 5 feet/hour, • The (maximum) difference between the exterior and Interior floodwater levels has been assumed with 1 foot during base flood conditions; a A factor of safety of 5 has been assumed, which Is consistent with design practices related to protection of life and property; The net area of openings (A,) as provided by the manufacturer. installation Recluirements and Limitations This certification will be voided if the following instal requirements and limitations are not enforced: • There shall be a minimum of two openings on different sic each enclosed area; • Tne bottom of each required opening shall be no more tlu aoove the adjacent ground level; • No temporary le.g, during cold weather) or permanent soi the automatic entry or exit of floodwaters at any time; • Where analysts indicates rates of rise and fall greater than accordingly to account for the higher rates of rise and fall. of Sit Model HxW [in] A. can:l An [it] ❑ 816CS 8 x 16 106 205 ❑ 122M 12 x 20 237 goo 0 1232CS 12 x 32 306 645 0 1616CS 16 k 16 134 395 0 1624CS 16 x 24 312 670 3632CS 16 x 32 408 835 ❑ 2032CS 20 x 32 630 1240 [31 2424CS 24 x 24 57D i230 0 2436CS 24 X 36 852 1765 Table 1 Maximum total enclosed area (A,) that can be served by each individual model based on the given net area of engineered openings (A;) cover may be placed into or over the nood vent that would block ft/hr, the total enclosed area as given in Table 1 shall be reduced Certifying Design Professional I .Ikol 111/Ni. _ NOW, Title Steve A. fled, President, Ged 8i Associates Address 2950 N 12* Avenue, Pensacbla, Fl. 3ZS03 Ucenw Florida Professional Engineer, U o. !
