Mr. Cardinal, I've just been looking at you on Google, and I'd encourage colleagues to look at Mr. Cardinal on Google. Some of the buildings you have designed, including the Museum of Civilization, now the Museum of History, are stunningly beautiful.
I only suggest in half jest that somehow or another you've done some thinking that's way deeper than the rest of us about how to design so that you are not creating construction waste unnecessarily, that you are not creating unnecessary pollution of some kind or another. I'd be interested if you could just share in a minute or two your thinking about how you design a building, and how that could help people like ourselves, who have no architectural background, think about how to create space.
