BuildingGreen's Michael Wentz has been coordinating for some time with DOE on case studies of the green rebuilding of Greensburg, Kansas, which had 90% of its buildings destroyed by a tornado in 2007. He described the work in a blog post here last year. Then, in a congressional address last February, President Obama cited Greensburg as "a global example of how clean energy can power an entire community," to which Michael added, "they are also a leader in green building including initiatives to work green building strategies into their building codes." A compelling hour-long documentary about what happened in Greensburg and the community's subsequent decision-making process in the wake of the two-mile-wide, F5 tornado is available to watch over the web.
