Yeah, but I don't want to do this: The town where people live underground: Welcome to Coober Pedy [1]. :( [1] https://www.youtube.com/watch?v=uFA-OB-nJ_I https

  No one said you have to go anywhere near that far. Thicker, solid walls with more thermal mass that soak up the overnight cool to release throughout the day. Better insulation and air sealing. Trees, roof overhangs, and shade cladding to prevent direct sunlight from hitting the house. "Just add a bigger AC" has been the approach for far too long, and it's not sustainable.

    Overnight low of 81° F in Houston tonight, and it probably doesn't get that cool until 2 am or so. There's no overnight cool to soak up. It's also super humid just to cooling more challenging.

      Sure, there will always be some nights in the height of summer where you want some AC. The goal isn't total elimination; it's reduction. Running AC in the dark night to cool that thermal mass will benefit during the day. Using some energy, but substantially less and at non-peak times. https://en.wikipedia.org/wiki/Climate_of_Houston https://en.wikipedia.org/wiki/Climate_of_Houston indicates 81 is above the average... and again, thick walls aren't the only available approach. Any approach will involve a collection of different tweaks.
