Boulder reviews 2024 building code updates with emphasis on solar requirements

On April 27, 2025, the Colorado Energy Office convened the fifth meeting of the Energy Code Board to discuss updates and future directions for the Low Energy and Carbon Code. The meeting highlighted significant developments in energy efficiency standards and the ongoing adoption process of new codes across various jurisdictions in Colorado.

A key topic of discussion was the adoption of the newly revised energy code, which aims to enhance flexibility while maintaining essential energy efficiency requirements. Carolyn, a board member, shared insights from Boulder’s recent code adoption process, emphasizing the importance of balancing prescriptive requirements with the need for resilient and efficient building practices. She noted that Boulder is moving towards mandatory energy credits for both residential and commercial buildings, expanding the list of options available to builders.

The board also addressed the integration of solar energy requirements within the new code. Carolyn pointed out that while the 2024 code prescribes solar energy use, there is a need for careful consideration of how these requirements fit within the broader context of Colorado's energy landscape. The discussion underscored the importance of ensuring that solar mandates do not compromise the overall efficiency and resilience of new homes.

Additionally, the board members expressed interest in reviewing updates to federal appliance standards, which could simplify future debates regarding furnace efficiency levels. This proactive approach aims to keep the board informed about evolving standards that impact energy efficiency discussions.

As the meeting concluded, members were encouraged to share any final thoughts or recommendations regarding the code standards. The collaborative atmosphere indicated a commitment to refining energy codes that not only meet current needs but also anticipate future challenges in energy efficiency and sustainability.

The discussions from this meeting reflect a significant step towards enhancing Colorado's energy efficiency framework, with a focus on flexibility, sustainability, and the integration of renewable energy sources. As the board continues its work, stakeholders can expect ongoing updates and potential adjustments to the energy codes that will shape the future of building practices in the state.
