GreenHomeNYC Open House Tour is a great way to explore the green buildings in NY. They will be doing a tour May 9th 2009. The first stop on their Brooklyn tour will be our Eco Brooklyn Green Show House in Carroll Gardens. To sign up for their tour go to greenhomenyc.org.
I did their tour last year and it was very fun and informative. GreenHomeNYC does some great work. I highly recommend taking advantage of their resources.
