Have architects always been asking these questions (about sustainability) or not? EVA raises questions! Iteration? Fast decision? Can we include build-nobuild questions? Not general ones Full material cycling in technical and biotic cycles, plus system design to facilitate. Can we make everything out of the waste of something else?
