Well, a bit off topic, but one can shade those south facing windows with an awning / overhang in summer, but still allow winter sun to enter given its lower angle. A good architect can do wonders...You have it figured out. My point is what happens when that patio / sunroom isn't opened? The ocean breeze most definitely helps tremendously also. What happens when it isn't sunny in the winter? Glass works against you. Does it not? There is no perfect solution for any home. You have to make adjustments accordingly. Too many variables. I am sticking to my guns on glass having poor R-Values and tons of losses and gains. There is just no way around it.
South facing solar homes prove this point. They want all the gain they can get thru that glass in the winter and they get it. That is how they obtain heat. They also shade that same south facing wall in summer because that same gain cooks them out. The hot glass even shaded kills their cool AC air too because it is radiated and transferred.
