What We Do


To foster transformative impact in our communities through green building education and advocacy.



A sustainable, healthy, and resilient built environment for all.

Founded in 2002, Green Building United (formerly Delaware Valley Green Building Council/DVGBC) is an independent 501(c)(3) nonprofit organization and an aligned chapter of the U.S. Green Building Council. We achieve our mission through the generous support of sustaining partners, individual members, donors, and funders.  

Our region includes the Greater Philadelphia area, Lehigh Valley, and State of Delaware (see a map of our region). As the region’s leading green building organization, Green Building United promotes the development of buildings that are sustainable, healthy for inhabitants, resilient, and cost effective.

Through education, advocacy, and strategic initiatives Green Building United informs and engages individuals and organizations to transform the way buildings and communities are designed, built, and operated. With more than 550 members and a dedicated network of volunteers, we are excited to see our impact continue to grow in the region.
