Unreservedly, one of the voices I respect most on issues of sustainability as it regards buildings is Marc Rosenbaum, a curious mix of wonk and Luddite. (When he announced that he'd started a blog, he assured his correspondents that he still didn't have a cell phone.)

But he does now have a blog, detailing his move to Martha's Vineyard and new housing, and how he is approaching the retrofit. These are adventures I'm eager to follow — and how I wish I could include Thriving On Low Carbon in my blog reader, but he appears not to be set up for that.

So here's the address.
