Measure Identification

Code change proposals are sometimes referred to as measure ideas. Measure ideas are submitted in either the nonresidential, multifamily, or single family sectors. If you have questions, contact the Statewide CASE Team at info@title24stakeholders.com

How are Code Change Proposals Selected?

At the beginning of each three-year cycle, there are many code change proposals in the Statewide CASE Team’s queue for consideration, which are sourced from previous code cycles, conversations with industry experts or other stakeholders, or direct recommendations via our code change proposal form.

Many criteria are used to evaluate the initial CASE proposal list including but not limited to: energy savings, cost effectiveness, technical feasibility, enforceability, adoptability, market readiness, and alignment with other state policy goals and CEC priorities. The initial list usually includes over 500 proposals. The Statewide CASE Team, with input from the CEC, uses the evaluation criteria to develop the final measure list, which ends up between 50-100 proposals. Once the list is culled, the CASE Authors get to work. CASE Reports require rigorous analysis and stakeholder engagement via public and individual meetings with stakeholders. On average, about two thirds of the Statewide CASE Team’s proposed measures are ultimately adopted by the CEC.

2025 Code Change Proposal Updates

The Statewide CASE Team will provide updates on code change proposal selections. If you have a code change proposal idea that you would like to submit for the Statewide CASE Team’s consideration, fill out the code change proposal form. The period for submitting ideas for the 2025 building energy code cycle has ended, but you can still submit proposals for the 2028 cycle.

The period for submitting code change proposals for the 2025 code cycle ended April 15, 2022—however, you can still submit code change ideas for consideration for the 2028 code cycle. Contact info@title24stakeholders.com if you have questions, and stay tuned for upcoming opportunities for additional stakeholder input.

2025 Code Change Proposal Submissions – Current Status

The below graphics show the number of submissions that the Statewide CASE Team has received thus far by building type and system type. These numbers will change over time as proposals are received and evaluated. The Statewide CASE Team considers a number of factors when screening submissions, including:

  • Initial Screening: Preemption concerns, regulatory scope, software requirements, permit/compliance requirements, data requirements, ASHRAE or IECC inclusion, relevance to long-term climate goals
  • Prioritization: Greenhouse gas savings potential, electricity savings potential, natural gas savings potential, environmental and social justice impacts, non-energy benefits (such as water conservation), adoption ability, code compliance and enforceability, cost-effectiveness, technical feasibility, and market readiness

2025 Code Change Proposals by Building Type

The following chart shows the number of code change proposals by building type and will be updated over time. In April 2022, the total number of proposals under consideration was n=645, up from n=392 at the end of 2021. The sectors are nonresidential, multifamily, and single family. As shown below, the most common code change proposals occur in the nonresidential sector.

2025 Code Change Proposals by System Type

The following charts track code change proposal categories within the nonresidential, multifamily, and single family sectors.
