Colorado Requires Localities Adopt One of Last Three IECC Codes

Colorado jurisdictions now must adopt one of the three most recent versions of the IECC as a minimum code, when they update any other building code.

The Governor of Colorado’s signing of HB10-126 is notable because Colorado is a home rule state. While this bill would allow jurisdictions to retain some freedom regarding their energy bill, it would also require them to use one of the model energy codes that were developed and published within the last decade.

Rep. Cathy Kipp, one of the bill’s sponsors, stated, “Bringing energy codes up to date is good for cities, good for residents, and good for our planet.”

The time frame for when the bill goes into effect is as follows: “By January 1, 2020, every Board of County Commissioners of a County which has enacted a building code and an energy code shall report the current version of their County’s building and energy codes to the Colorado Energy Office. Thereafter, every Board of County Commissioners is encouraged to report any change in their County’s building and energy code
to the Colorado Energy Office within a month of changing their County’s building and energy codes.”

The Governor also signed HB19-1231 into law in late May. This is the bill that sets water and energy efficiency standards in the state. As a reminder to our reporting from March 2019, some of the referenced standards apply to appliances found in restaurants and commercial kitchens (fryers, steam cookers, etc.).

Here are some of the standards that could be applicable to residential dwellings:

• Starting in 2020, general service lamps must meet or exceed a lamp efficacy of 45 lumens per watt.
• Starting in 2021:
o Computers and computer monitors must meet the requirements of Section 1605.3 (v) of Title 20 of the California Code of Regulations (CCR).
o Kitchen faucets and aerators must have a max flow rate of 1.8 gpm, with an optional
temporary flow rate of 2.2 gpm.
o Residential ventilating fans must meet Energy Star v3.2 specs.
• Spray sprinkler bodies that are not excluded from the WaterSense v1.0 spec must include an internal pressure regulator and must meet the water efficiency, performance criteria and other requirements of that spec.
