Out of curiosity I just had a look at some older Miami homes on the net because in Australia we recognised tall ceilings as a mistake fairly early on, once the air heats up in there it's trapped so the great majority of our homes are only single story with a low pitched roof and no room for an attic. None of us have basements either.
In the pictures I saw on the net too a lot of the older homes in Miami had done the very European thing with very little roof overhanging the walls, here there's at least a 3 foot overhang all the way around on every house to keep the walls shaded during the middle of the day where as in Europe they try to catch as much of that heat as possible.
Big verandas at least on the northern side of the house is a must here, and in Queensland and Darwin many of the houses are elevated up on stilts to try and catch the breeze.
This is the house I grew up in, been a few years (more than 30) since I've seen it, they've replaced all the window frames.
