Questions about whole house ventilator fan and attic insulation

15 years ago

We really would like one of those old fashioned noisy whole house fans. We live in the perfect climate for using one of those because with our temps rarely getting over 85, we could use that almost all of the time and never use the air conditioner. And by the way, we love the noise....I have to have a fan blowing in the dead of winter just for the sound of the motor. However I am concerned with how such a thing would affect our energy efficiency. Where does the air go when it goes into your attic? If we have our attics insulated with isolene foam won't the attic be too tight for the air to escape? Would a whole house fan negatively affect our possibility of getting an Energy Star rating or a healthy built certificate? Please enlighten me.
