Appliance Efficiency Compliance

The Appliance Efficiency Program requires that the manufacturers of certain appliances meet state and federal standards for energy and water efficiency. Manufacturers must also certify the performance of their appliances to the Energy Commission to demonstrate compliance with the standards and make this information available to the public.

Modernized Appliance Efficiency Database System (MAEDBS)

All appliances regulated under Title 20 must be certified to the California Energy Commission using MAEDBS.

The Energy Commission will no longer accept appliance certification submittals and applications through email. Manufacturers, test laboratories, and third party certifiers will need an account to perform actions within the database, including submitting data.
