Energy Codes

Energy Code Resources

EcoAction Partners is facilitating a regional cohort across San Miguel, Ouray and San Juan counties to support collaborative discussion and implementation support for the state's building energy code requirements.  Regional building code consistency, with varying amendments as appropriate for each jurisdiction, has proven beneficial to the regional building community and for enforcement over the years. This work is funded by the Energy Code Adoption and Enforcement Grant Program, from the Colorado Energy Office, and supported by Lotus Engineering & Sustainability and NORESCO.
