Hi Soo Kim,
I don't have anyone to recommend, unfortunately, but I did work as an editor at an Architecture magazine here in Toronto that takes a huge interest in sustainable architecture. They run a Green issue every year and it's thoughtful. Really parses what we mean by green and doesn't seem to be after the ad dollard like a lot of publications. If you would like me to pass on the name of an editor there for a potential interview, I'd be happy to do so. Best of luck in your search!
