I spent much of last year in Southeast Asia within ten degrees of the equator and rarely had A/C. It wasn't a problem for me, though my computer was often unhappy.

I went to Egypt as a teenager and remember the temperature in Sharm el Sheikh cracking 50C. We would literally sprint from the A/C in the hotel across the beach to the water because the sand was too hot to walk.

Equivalent latitude doesn't mean equivalent climate. As an example, which of these cities is further north, Buffalo, NY, USA or Cannes, France? Hint: it's the one known for topless sunbathing, not the one known for sub-zero outdoor football games.

There are a lot of people living in Egypt who don't have to imagine that.

But obviously you shouldn't make such big/poorly insulated houses then.
