CGBG hosts monthly events for our members, from educational Brown Bag talks and informative tours, to regular social evenings and of course, our flagship event, the Boulder Green Home Tour! These events are a great way to connect and network with other like-minded professionals in the industry, as well as expand your education within the field of green building within our community and beyond.



We provide the ability for members to connect on our platform. Connecting with other CGBG members, sponsors and partners allows individuals and professionals to become more active and influential within their industry.
