2022 Cycle Impacts
Thank you to all who contributed to the 2022 code cycle development process. The resulting code changes will provide significant energy savings to Californians. Below are the estimated impacts of Codes and Standards Enhancement (CASE) initiative efforts by type of energy, code cycle year, building type, construction type, system, and measure.
For a summary of all 2022 code cycle changes and their estimated impacts (which include those from the CASE team along with many other stakeholders), view the California Energy Commission’s 2022 Building Energy Efficiency Standards Summary.

Electricity:
1,034 GWh
equivalent to the annual electricity usage of
133,150 homes
Peak Demand Reduction
132.8 MW

Impacts by Code Cycle
We made even bigger strides this code cycle, particularly in electricity savings. Each code cycle builds on the previous cycle’s work. Our collective impacts help make California’s energy landscape brighter and more resilient.
Natural Gas First-Year Savings by Code Cycle
