Wow! This group is AMAZING, and it's literally an honor to be the first to comment on their Yelp page. I cannot believe I'm the first! This is bar none the single most important and well recognized source of unbiased green building news in the US. (period). Time and time again they put out position papers, Environmental Building News, and collaborative efforts (e.g., Pharos) that really help shape the green building movement for the better. Their online materials database (aka GreenSpec) is a phenomenal resource for those interested in finding more sustainable (and healthy) building materials. Huge supporter! Keep up the great work!
