This document summarizes a lecture on buildings from an NYU course. It discusses past lecture topics on clean tech failures and the Passive House movement. The main topic is paradigms - the shared beliefs that form the basis of a system. It says paradigms give rise to goals, rules and other system elements. Changing paradigms is difficult but can be done by pointing to failures in the old paradigm and asserting the new one. The document outlines assigning students to explore concepts for changing how buildings are made and maintained by focusing on anomalies and possibilities for change.
