I am no expert on the matter, i have a hoop house in mid France, it was 48 degrees Celsius in there a week ago, it's only May. It is open on both sides and still very hot at times. Unbearable, sauna like temperatures. It's shaded by a giant ash tree closeby from around 4 o'clock.
Where you are it is much hotter and the sun more intense.
Ddn't Geoff Lawton have this series about greening the dessert? Maybe they have got more information.

I've seen people here in France who have these houses, they're low at the back into a hill for instance and the roof is one piece slightly angled up, with big open windows in the front, but the roof has an overhang of two metres or something. It was facing south. And they had calculated the angle of the sun in summer and in winter time. The overhang blocked the high sun from shining and heating the place in summertime, because it is underground, the earth mass coolness kept the place cool. In winter the place was kept warm because the sun was low and could shine under the overhang and warm the place up passively. Beautiful design. I can imagine in your case even this will be too hot in summer, then you could have something like a grapevine growing in front of the window to keep the reflected sunrays from entering, the effect is very nice. Maybe a climbing plant like a wisteria on a rack to prolong the overhanging roof. In winter it will have lost the leaves, i don't know if grapes and wisteria grow where you are, but there must be something that has leaves in summer and drops them in winter, or not?
In the Geoff Lawton series there was this lady who was propogating plants on the north side of the house, it cost less water and was less hard on the plants.
