Robrt, thanks for this great article on shade. I am a huge proponent of it. I particularly enjoyed your reference to the mushrooms at the Beatitudes Campus, where my husband works. They are awesome.
I disagree with you about mid-century modern architects ignoring shade. For example, Haver buildings offered plenty of shade and smart passive solar design. I think we lost a good chunk of our common sense in the eighties and nineties, but more and more, we're seeing well shaded buildings again.
