SHGC of north-facing windows?
I’m beginning the search for windows for my new home in Detroit, CZ5. South windows will have a high SHGC. West windows will have a low SHGC. The east windows get summer shading from a large oak tree so will have a high SHGC. My question is about north windows. Of course they won’t be subjected to sunlight, but my first thought is that a window with a low SHGC will better reflect indoor heat back inside? I would prefer to be wrong because high SHGC windows let in more light.
