In 2001, a small group of volunteers came together around a common interest in sustainable design and building to start Delaware Valley Green Building Council. The goal to educate and advocate for green building practices across the region unified the founding group of contractors and architects, engineers and policy advocates – many of whom are still engaged with our work today. Like our founders, we are unified in our goal to advance sustainable building solutions to match the scale of the challenges we face. Green Building United is made up of committed practitioners, passionate advocates, and dedicated volunteers.
