From The Energy Bulletin a posting of a panel discussion about energy and urban design. James Kunstler is one of the panelists, Nikos Salingaros is the other. Part 2 is here.
Pay attention to what they have to say about skyscrapers (New York is their focus) and consider what it may mean for the Loop and Streeterville. Also, LEED certification is only as good as its practitioners. They also comment about density, and assert that skyscrapers, used to promote density, are actually very inefficient, with or without solar panels.
Rogers Park, for all its issues, is still better situated than the Loop to survive and thrive in an energy constrained future. Will we have the wisdom to build on that?
