I would like to install a whole house fan in my 2400 sf house. However, with only three 1 ft x 2 ft gable vents, I'm looking at an NFVA of only 3 sf of exhaust vent when taking into consideration that they are screened!
I'm assuming that I would need ~10 air exchanges per hour to get a "breeze effect with the fan turned on. However, I would need an additional 4sf of exhaust vent: 3500cfm/500cfm/sf = 7sf - 3sf existing exhaust vent.
I currently have 1.17sf of soffit intake vents (84 3" holes under eaves) vs 6sf exhaust vents(3 gable vents). Since these vents should actually be same ratio, by adding 4sf of additional exhaust vents, the ratio would be even more skewed!
The Quiet Cool website suggested that an attic power vent could be run in tandem with a whole house fan and eliminate the need for additional exhaust vents to be installed on the roof. With that said, would this be the best solution for my dilemma?
