nrel data indicate july is the worst-case month for ac in mobile, when
1770 btu/ft^2 hits the ground on an average 82.3 f day with a 73.2 f min
and humidity ratio w = 0.0169 pounds of water per pound of dry air.
very humid...

the techniques in that book won't help much. baruch givoni's 1998 climate
consderations in building and urban design has more on design for hot and
humid climates, but that book won't help much either, compared to serious
air conditioning.

that won't help, in humid climates. offgridman might enjoy ceiling fans
and an airtight house with a licl solar still on the roof, which might
also heat water for showers. i could help, if he wants to get into that.
we've proposed another all-day workshop on solar heating and natural
cooling for the 2005 ises/ases conference in orlando in august. it would
be nice to have a working example of this new liquid desiccant technique.
