  I live in a place with similar temperatures to Las Vegas, and, I think the trick might be to have a very sealed up house, with very good insulation. And then, suck in as much cold nighttime air as you can, perhaps even running the AC at night since it is more efficient, and then try to ride that cold air through the day.

    I do this as much as possible and it generally works fairly well. Less so now that the power company cut down a tree that helped shade my roof, but I can usually make it into mid-afternoon before having to kick the AC on during the summer highs. High Desert in SoCal for reference.

    Thats how lots of large commercial buildings do it. Make huge blocks of ice in the middle of the night when energy is cheap and the building's heat load is at a minimum, then melt the ice and use the phase change of water to absorb as much heat as possible. Also why its colder in the morning and it feels like the building is a bit too warm to be comfortable if you stay late. This, of course, varies from building to building.
