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 have the same mission, vision, and values, and will continue to provide the same dynamic level of membership and sustaining partnership opportunities and benefits, as well as events and activities.
