my sense is that most programs have incorporates some sustainability elements, and that if you have a background in that sort of stuff, almost anywhere will be open to you including it in your projects.

that said, i would recommend checking out the rural studio program through Auburn University, Alabama, and the Univ. of Virginia program. Univ. of Utah Salt Lake has a "design build bluff" program modeled on the rural studio and Sam Mockbee's work. Also, UMASS Amherst has a newly accredited program that I would guess will follow closely in the mold of its very progressive LARP (Lands. Arch / Regional Planning) program.

I'm in the middle of applying to a handful of these programs. Happy to talk more if you have questions or want to network.

Hey there...

You should check out Carnegie Melon, as they have (had?) the first Sustainable Design Masters program. The only downside is it may take 3 or more years since you don't have a pre-prefessional architecture degree. University of Oregon I hear is also strong on sustainability, and Washington University in St. Louis. I'm at University of Maryland for undegrad currently, and we're trying to build up the sustainability focus, especially after our second place in the 2007 Solar Decathlon. I started an Emerging Green Builders group here last year as well.

Good luck in your search, and please share any good schools you find!
