Not sure how its in US, but houses here in some parts of Europe have literally become completely plain white cubes to minimize building costs as much as possible. No more roof overhangs (which brings problems), no more awnings, no decorations, practically no balconies or varied designs. Just sets of suburban white cubes.
There's a crop of these hideous things I've seen around Germany, Austria, France, Switzerland and rest of central Europe.
The other thing the builder did foam insulation of the garage doors and walls. Easily 20F difference from my previous house in the same area. Reflective ridged insulation in the attic too. My old house 110 easily, in the summer. It is basically the same temp as the outside now. Cost for the AC is basically half what my pervious house was. I would go for awnings at this point as it is basically one of the few things left I could realistically do. But HOA...
Unfortunately, the truth of both those places, and in fact all the strict Modernist/Brutalist buildings of the postwar period, is that rain absolutely f*ks them over. No amount of tar paper, roofing tile, etc., can help against a flat roof, frequent precipitation, and a temperature climate.
Either way it's not a sufficient solution because AFAIK even the best solar protection glass will let 1/3 of the sun's heat in, which is an enormous amount when you have long summer days.
