Why did you change your name and branding from Delaware Valley Green Building Council/DVGBC to Green Building United?

We wanted a brand and name that reflected our history, aligned better with our current work and future aspirations, and signified the unification of the green building and sustainability community. While our name has changed, we continue to provide robust membership and sustaining partnership opportunities and benefits, and many other dynamic engagement activities. 


What does Green Building United do?

Through education, advocacy, and initiatives, Green Building United informs and engages individuals and organizations to transform how buildings are designed, constructed, and operated.  With the built environment accounting for a significant portion of carbon emissions, and systemic social disparities tied to development, buildings serve as critical leverage points for addressing climate change and improving equitable living conditions for all building occupants.

Our office is located in Center City Philadelphia (2401 Walnut Street, Suite 103) and our region includes the greater Philadelphia area, Lehigh Valley, and the State of Delaware.
