That’s basically making the best with what shitty technology there was back then. It’s not nearly as good as air conditioning or else people would just build houses the same way. Essentially the entire Phoenix valley is unlivable in the summer without energy assisted cooling either with A/C or evap. The native Americans didn’t even live down low during the summer. You can’t beat physics with some well placed windows. The “deep south” you referred to is about as easy of a climate you can get to live in the continental US without energy assistance apart from maybe Southern California. The air conditioning energy spent to cool down a home 15 degrees in the summer in Mississippi is a drop in the bucket compared to what it takes to heat New York or Minneapolis homes in the dead of winter.
