Just window fans and shutters can go a long way to keeping houses cool. A tactic I like to use a lot in the wee months of the summer is to use a window fan to let cold air in at night, then put the shutters up during the morning to try and keep the night cold air inside as long as possible while still having some ventilation. Along with a ceiling fan this works very well, unless the night doesn't cool down enough.
