This chapter is intended as an epilogue, and as a means for students and others who so desire to peek behind the curtain and see the Great and Terrible Oz at work. At a recent college reunion, some of my former classmates and I reminisced over wine about the good old days of Environmental Building Systems lectures. One of them remarked, “Oh, I hated that class. So boring. Nothing but charts and graphs and Trombe walls.” I, not surprisingly, love all three of those things, but I have discovered over the years that I am in the minority. So I have dedicated the last eight years of my academic life to finding ways to inculcate the ideas embedded in those charts, graphs, and yes, even the inventions of Dr. Felix Trombe, 1 in my architecture students (Figure 6.1).
