When I lived in E. TN. we installed a 'whole house fan' in the central
passageway of the house. The idea was that there would be times of day when
it was hotter in the house than outside, so you'd pull the outside air in to
cool it down or at least even it out- the 'exhaust' went into the attic and
displaced the hot air built up in there which exhausted thru the vents which
in turn further cooled the house. You'd run the fan in the morning and in
the evening and use the A/C during the hottest part of the day. This also
had the benefit of thoroughly airing out the house. I was skeptical about it
at first but it worked very well in the humid environment.
Here (SoCal desert) you have the variation of using a swamp cooler to push
outside air in, and upducts in the ceiling to vent that air into the attic
for the same reasons as the other.

Cya,
Robert
