Green Prefab debate

Yesterday we had a great time debating about Green Prefab at Treehugger with our Master of Ceremonies, Lloyd Alter, Chad Ludeman of the very cool (and smart)100k House, Allison Arieff and Preston Kroener of Jetson Green.
You can watch it HERE (I recommend fast forwarding through the first few minutes while we get our skype act together and therefore miss us talk about being hungover).
