Building Energy Codes Legislation
The Colorado General Assembly passed the Building Energy Codes law (HB22-1362 Building Greenhouse Gas Emissions) in May of 2022 to improve energy use and efficiency in buildings. An updated energy code is an important tool to increase building efficiency and meet the state’s economy-wide greenhouse gas emissions reduction target of 50% by 2030 and 100% by 2050 from a 2005 baseline. 2021 Colorado Greenhouse Gas Pollution Reduction Roadmap.
This law advances this progress by directing the Colorado Energy Office (CEO) and the Department of Local Affairs (DOLA) to jointly appoint and convene the newly created Energy Code Board to review, approve, and recommend energy codes for new buildings and retrofits to existing buildings. The bill specifies the composition, objectives, and operating procedures of the new Board. The legislation directs the Energy Code Board to perform the following work:
- Model Electric Ready and Solar Ready Code - the Energy Code Board developed and adopted a model electric ready code and solar ready code with the intent to prepare new homes and buildings for electric vehicles, rooftop solar, and high efficiency electric appliances. The model electric ready and solar ready code was published on June 1, 2023. Cities and counties with building codes must adopt at least the 2021 International Energy Conservation Code (IECC) when they update other building codes between July 1, 2023 and July 1, 2026. This adoption must include the electric and solar ready provisions in the model electric ready and solar ready code.
- Model Low Energy and Carbon Code - the Energy Code Board will develop and adopt a model low energy and carbon code with the intent of minimizing overall carbon dioxide emissions associated with new and renovated homes and commercial buildings, based on either the 2021 IECC or the 2024 IECC, plus any appendices and the model electric ready and solar ready code. This code must be adopted by the Board on or before June 1, 2025. Cities and counties with building codes must adopt the model low energy and carbon code when they update other building codes after July 1, 2026.
In addition to the work of the Energy Code Board, the Colorado Energy Office is directed by this legislation to perform the following work:
- Model Green Code - CEO will promote a model green code that local governments may voluntarily adopt, in addition to the required energy code. The model green code will address building attributes such as energy efficiency (above minimum code), water efficiency, and embodied carbon in building materials.
- Code Training and Adoption Assistance and Building Upgrades - the Legislature appropriated $4 million for CEO to provide funding to local governments for energy code adoption and enforcement, energy code training, and technical assistance, along with $21 million to support decarbonization of public buildings and communities with a focus on incentives for lower income households and historically disadvantaged communities.
