The comments two and three levels up were about third-world tropical houses and old houses respectively, both designed to be habitable in hot climates without air conditioning. As such, they are/were designed exactly the opposite way: to maximize cross-ventilation instead.
What you really want these days would be a house that's tightly insulated but also has lots of operable windows, a whole-house fan, and/or a design that facilitates stack effect ventilation so that it can use either cooling strategy when conditions are appropriate.
