Much much better than a/c is underground pipes. Run 4" pipes under the
garden and fan air in through them in summer. Same result as a/c, but
uses a tiny fraction the energy.

Also a whole house fan that cools the house down in evening and night
by drawing air in at bottom and out the top. Put the fan in the attic.

Also ceiling fans, one of lifes real bargains.

Summer comfort is important in design, neglect it and people will end
up resorting to a/c.
