Proper insulation is way more efficient than AC. One of the main reasons there is so much AC in the US is because many buildings aren't well-insulated and historically energy has been incredibly cheap.

Insulation doesn't substitute for AC if the lows aren't low enough to cool thing down at night.

  No, not entirely, but it complements AC. Proper insulation means that much less energy is needed both to cool and heat a building.
