BuildGreenCT is a membership-based nonprofit organization working to raise awareness, promote green building design and construction, and advocate for high-performance energy-efficient buildings at state and local levels.

Your membership helps support our efforts to develop high quality programming, including building tours and special events.

Thank you for your most important participation and support.

Two Types of Membership

Individual Membership is open to anyone with an interest in energy efficient, healthy sustainable buildings and places.
