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

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.
