I'm late to the party here, but I'll chime in anyway. Are we talking existing construction or new? If new I would go with ICF construction. Super high R value like 60 +. Then some really good windows with a big spacer (the part that holds the panes of glass apart) with Krypton gas fill. (Argon is cheaper but also less efficient)
If existing structure and you really want to kill the heat you can add a layer of insulation foam to the outside of the structure, a couple inches thick and then reside it. Upgrade windows and put on a lighter colored roof that will reflect heat instead of absorbing it. Seal all cracks and eliminate heat producing electrical stuff in the house.
