Yes, if you are planning a major renovation or remodel in Denver, your project will need to comply with the Model Low Energy and Carbon Code (MLECC).
Denver has adopted the MLECC with a timeline that makes these standards mandatory starting in 2026. Because the code targets lower carbon emissions and greater energy savings, your remodel must meet several high-performance benchmarks.
Key compliance requirements for Denver projects include:
- Thermal Envelope: You must meet strict insulation standards, specifically R-49 for attics and R-20 for walls. Wall insulation typically requires continuous insulation (such as polyiso) to minimize thermal bridging.
- Window Performance: Effective July 2026, new windows must have a U-value of 0.30 or lower and a Solar Heat Gain Coefficient (SHGC) of 0.25 or lower. These align with the Energy Star window requirements 2026 Colorado standards.
- Air Sealing and Electric-Ready Provisions: The code requires enhanced air sealing measures and “electric-ready” provisions to support future home electrification.
Compliance with these standards not only ensures your project is legal and permitted but also positions your home for Energy Star Most Efficient 2026 tax credit eligibility, helping to offset the cost of high-performance upgrades.
