you might be able to do this automatically by leaving an attic hatch open
and hanging some dry cleaner bags over the insides of downstairs windows.
when the house is warmer than the outdoors, air would flow in the windows
and up and out the attic hatch. the plastic films would block reverse flow
during the day.

you might use a differential thermostat to turn it on when the house
is warmer than the outdoors, with a series cooling thermostat set to
something like 60 f so the house doesn't get too cold.
basements have lots of thermal mass, and we can add more, eg 4" sewer pipes
between the rafters. maybe we need two loops, one to cool the basement with
outdoor air as fiercely as possible and one to circulate house air through
the basement as needed. this could become known as a thermal recirculation
energy conservation system, aka "two loops le trec."
