[Strawbale] Blower Door test set-up

[David Neeley]

What I don't quite understand is how the inside/outside pressure
comparison fully handles the situation. I can see it may at least
partly, but doesn't the pressure from prevailing winds vary with such
differences as wind speed, direction, windbreak locations, and the
profile of the building?

For example, in high winds I would expect the air pressure on the back
side of a shed roof would be quite different from the air pressure
behind a hip roof, as one example. Or would this pressure difference
be too small to have an effect?

As far as constructing a near net-zero energy house, it seems to me
that the best method might be to make one as tightly sealed as
possible while incorporating an energy recovery ventilator for the
needed air exchanges inside. That is exactly what I contemplate doing,
at this point anyway. Would this strategy be wrong?
