Late

Due to the delayed timeline of the 2024 IECC code books and the shifting legal landscape on building electrification requirements, the Northwest Regional Code Cohort is revising the original Net Zero Roadmap. The new Roadmap was finalized in June of 2025. In addition, the State is currently developing the low energy and carbon code requirements. Final State low energy and carbon code will be finalized in Sept. Due to the delays and overlap with the State's requirements, the cost analysis is delayed. All of these factors have resulted in a delay in bringing code amendments to City Council. A discussion on which code pathway to pursue will be going to City Council in Aug. 2025.

This strategy focuses on developing a net zero building code for residential and commercial construction to accelerate and incentivize energy efficiency and renewable energy in new construction. The code would provide opportunity, pathways, and incentives, for net zero construction ahead of forecasted code requirements.

This strategy has been combined with Climate Action Recommendations Report strategy CARR BE.1: Building Codes: Improve Building Codes to include energy conservation measures and promote renewable energy.

  1. Solar ready and EV ready homes are now part of the 2021 International Residential Code (IRC). Strengthening amendments for commercial solar and EV-readiness were not included and will be considered with the 2024 IECC cycle, along with the Northwest Metropolitan Regional Energy Code Cohort recommendations.
  2. Staff will be taking the Northwest Metropolitan Regional Energy Code Cohort recommendations for possible inclusion in the 2024 code update.
  3. Staff are reviewing State Energy Code requirements for amendments to the Longmont Code for more progressive requirements for electric preferred options.
