Founded in 2004, the guild was the vision of a group of building professionals who decided it was time to make a significant, positive impact on the Boulder community. Colorado Green Building Guild strives to ensure the widespread adoption of sustainable practices to increase the efficient use of resources, create healthier buildings, and support vibrant, sustainable communities throughout Colorado. Through community events, from educational workshops and themed seminars, to Happy Hours, Green Home Tours and networking opportunities, the guild offers its members, sponsors and partners the chance to share their knowledge, increase their business opportunities, support a clean energy economy and make sustainable building common practice throughout the state.
