Both sashes operate and tilt inward. Top-down ventilation, cleaning from indoors, and the smartest choice for anything on a second story.

Two operable sashes in one frame. Both slide vertically, and both tilt inward. That second feature is the whole reason people choose it: you can wash the exterior glass while standing in your own bedroom, which matters enormously when the window sits on a second story above a gravel side yard.
A double hung has more moving parts than any other common style, so the hardware and the seals have to be rated for real desert heat cycling.
Low-E coatings with a low SHGC, argon fill, and warm-edge spacers. We target roughly 0.20 to 0.27 SHGC on the elevations that take the afternoon sun.
Block-and-tackle or constant-force balance systems rated for high-heat cycling, tilt latches that survive daily use, and cam locks that pull both sashes tight.
Vinyl for the best value, fiberglass for thermal stability, and clad wood where the interior look drives the decision. UV-stable dark finishes available.

On a second story, almost always. Being able to tilt both sashes in and clean the glass yourself pays for itself over the life of the window. On a single story where you can reach the glass with a hose, the case rests more on ventilation than on cleaning.
In the shoulder seasons, yes. Hot air stratifies against the ceiling, and dropping the upper sash lets it escape without letting the dog out. In July, with the AC running, keep everything shut.
In principle. In practice it comes down entirely to the balance system and the weatherstripping. We only quote hardware rated for high-heat cycling, because a balance that fails in a Phoenix attic-adjacent bedroom is not a theoretical problem.
No, provided the weep and seal design is right. Two sashes is not the problem. A cheap window is the problem, and that is true of every style on this site.
