Section 30-28-211 - Energy efficient building codes - legislative declaration - definitions(1) The general assembly hereby finds and declares that there is statewide interest in requiring an effective energy efficient building code for the following reasons:(a) Excessive energy consumption creates effects beyond the boundaries of the local government within which the energy is consumed because the production of power occurs in centralized locations.(b) Air pollutant emissions from energy consumption affect the health of the citizens throughout Colorado.(c) The strain on the grid from peak electric power demands is not confined to jurisdictional boundaries.(d) There is statewide interest in the reliability of the electrical grid and an adequate supply of heating oil and natural gas.(e) Controlling energy costs for residents and businesses furthers a statewide interest in a strong economy and reducing the total cost of housing in Colorado.(f) More recent energy codes are more effective at ensuring building durability and structural integrity and protecting public health and safety through better: (I) Moisture management to prevent mold, mildew, and rot;(II) Airflow management; and(III) Protection during severe weather.(g) More recent energy codes incorporate newer building technologies, techniques, and materials and offer more options for builders.(h) Businesses and residents in low-income communities and rural areas of the state deserve at least the same durability, health and safety, and energy cost savings from energy efficient buildings as those in wealthier, urban, and suburban areas of the state.(i) Highly energy efficient homes and buildings can reduce energy use and help consumers save money on energy bills.(j) Highly energy efficient and low-carbon new homes and buildings are critical for meeting the greenhouse gas pollution reduction targets established in section 25-7-102 (2)(g).(2) As used in this section, unless the context otherwise requires: (a) "Building code" means regulations related to energy performance, electrical systems, mechanical systems, plumbing systems, or other elements of residential or commercial buildings.(a.5) "Colorado plumbing code" has the meaning set forth in section 12-155-103 (5).(a.8) "Elevator and escalator code" means the rules adopted in accordance with section 9-5.5-112.(b) "Energy code" means a subset of building codes related to the total energy performance and carbon emissions of residential and commercial buildings.(b.5) "International energy conservation code" means the energy code published by the international code council or a successor organization.(b.8) "National electrical code" has the meaning set forth in section 12-115-103 (8).(c) "Office" means the Colorado energy office created in section 24-38.5-101, C.R.S.(3) Every board of county commissioners that has adopted and enforced one or more building codes, or that adopts and enforces one or more building codes after July 1, 2022, shall adopt and enforce an energy code that applies to the construction of, and major renovations and additions to, all commercial and residential buildings as required by the energy code in the county to which the building code applies.(3.5)(a) A board of county commissioners that has adopted and enforced one or more building codes, and that updates one or more building codes on or after July 1, 2023, and before July 1, 2026, shall adopt and enforce an energy code that achieves equivalent or better energy performance than the 2021 international energy conservation code and the model electric ready and solar ready code language developed for adoption by the energy code board pursuant to section 24-38.5-401 (5) at the same time other building codes are updated.(b) A board of county commissioners that has adopted and enforced one or more building codes, and that updates one or more building codes on or after July 1, 2026, shall adopt and begin enforcing an energy code that achieves equivalent or better energy and carbon emissions performance than the model low energy and carbon code developed for adoption by the energy code board pursuant to section 24-38.5-401 (6) at the same time other building codes are updated.(c)(I) Notwithstanding subsections (3.5)(a) and (3.5)(b) of this section, a board of county commissioners representing a rural county is required to adopt and enforce an energy code that achieves equivalent or better energy performance than one of the last three most recent editions of the international energy conservation code rather than either an energy code that achieves equivalent or better energy performance than the 2021 international energy conservation code and the model electric ready and solar ready code language identified for adoption by the energy code board pursuant to section 24-38.5-401 (5) or an energy code that achieves equivalent or better energy and carbon emissions performance than the model low energy and carbon code identified for adoption by the energy code board pursuant to section 24-38.5-401 (6) if, while the grant program established pursuant to section 24-38.5-403 is accepting applications, the board of county commissioners applies for and is not awarded a grant that significantly assists in energy code adoption and enforcement training.(II) As used in this subsection (3.5)(c), a rural county means a county with a population of less than thirty thousand people, as determined pursuant to the most recently published population estimates from the state demographer appointed by the executive director of the department of local affairs.(d) When adopting or updating a building code prior to July 1, 2023, a board of county commissioners shall adopt and enforce an energy code that achieves equivalent or better energy performance than one of the three most recent editions of the international energy conservation code.(e) Notwithstanding the timing requirement of subsection (3.5)(a) of this section, a board of county commissioners may comply with subsection (3.5)(a) of this section when the board adopts one or more building codes other than the national electrical code, the elevator and escalator code, and the Colorado plumbing code, or by June 30, 2026, whichever is earlier, if:(I) The board of county commissioners adopts or updates: (A) The national electrical code by reference when adopted or updated by the state electrical board;(B) The elevator and escalator code by reference when adopted or updated by the director of the division of oil and public safety within the department of labor and employment; or(C) The Colorado plumbing code by reference when adopted or updated by the state plumbing board; and(II) The adoption or update of the national electrical code, the elevator and escalator code, or the Colorado plumbing code occurs on a timing cycle different from the scheduled adoption or update of one or more building codes other than the national electrical code, the elevator and escalator code, or the Colorado plumbing code.(f) Notwithstanding the timing requirement of subsection (3.5)(b) of this section, a board of county commissioners may comply with subsection (3.5)(b) of this section when the board adopts one or more building codes other than the national electrical code, the elevator and escalator code, and the Colorado plumbing code, or by June 30, 2030, whichever is earlier, if:(I) The board of county commissioners adopts or updates:(A) The national electrical code by reference when adopted or
