I Was Told There Would Be No Math – How to calculate proper ventilation
Figure 4 – Example building for determining the minimum ventilation amount (figure courtesy of the ICC).A discussion on attic ventilation isn’t complete without going over the calculations to determine the minimum required net free ventilating area (NFVA). The following is an example shown in the IRC commentary for a simple gable roof using the 1:300 ratio. See Figure 4.
Attic floor area = 20 ft. x 50 ft. = 1,000 ft.2
Required NFVA = attic floor area x 1/300
Convert sq. ft. into sq. in.: 3.33 ft.2 x 144 in.2/ft.2 = 480 in.2
Ridge NFVA (50%) = 480 in.2 x 0.5 = 240 in.2
Each soffit NFVA (25%) = 480 in.2 x 0.25 = 120 in.2
Therefore, there should be 240 sq. in. of NFVA located at the ridge and 120 sq. in. of NFVA located at each soffit.
