What happens when modular construction, passive house principles, and workforce development are designed to reinforce one another?

Project Ponderosa in Boulder, CO offers a compelling answer. Born from the aftermath of the 2013 floods, this initiative brings together the City of Boulder, Flatirons Habitat for Humanity and BVSD to go beyond basic recovery work.

The project redefines how communities can build with intention, aligning construction quality, affordability, and local capability.

Thank you to all who joined us for Colorado Green Building Guild's annual holiday party last week, hosted on Alpen's factory floor! We loved having the opportunity to reflect on the past year with builders, architects and energy pros driving Colorado’s high‑performance building future.

As the year comes to a close, keep an eye out for other upcoming CGBG events leading into 2026, connecting the community to knowledge, collaboration opportunities, and the advancement of sustainable building practices across Colorado.
