Should the Home windows are open up in the house there's no "cooling penality" to acquiring some air exhausted from in the attic. if late in the afternoon the house temps rise above the outdoor air temps there is actually a cooling advantage. (we hope the quantity of air staying exhausted in the attic ground is minimal because the house is air sealed).

Continue to, an illustration calculation for an average dwelling in New Jersey, and One more in Vermont, could be enlightening. My guess is this way a lot more attention really should be provided to developing a flawless air seal within the protect than to including a couple of more Rs on the R-worth.
