Based on the provided guide, several Colorado jurisdictions are scheduled to adopt or implement the Model Low Energy and Carbon Code (MLECC) by 2026. While the code establishes a statewide baseline, local adoption timelines vary.
The specific jurisdictions required to meet MLECC standards by 2026 include:
- Denver: This jurisdiction is scheduled to adopt the code by the end of 2025, with compliance becoming mandatory in 2026.
- Unincorporated Arapahoe County: This area has an adoption date set for July 2026.
- Centennial: The code is currently under review, with expected adoption in 2026.
In contrast, Colorado Springs has delayed its adoption of the MLECC until 2027.
For most jurisdictions adopting by 2026, building requirements will tighten significantly. For example, in Denver, Centennial, and Unincorporated Arapahoe County, new projects must meet stricter thermal envelope standards, including R-49 attic insulation and R-20 wall insulation with continuous insulation. Additionally, windows installed after July 2026 in these areas must meet a U-value of 0.30 or lower and an SHGC of 0.25 or lower to align with the new energy standards.
