The bill amends the "Appliance and Equipment Energy and Water Efficiency Standards Act of 2021" to enhance definitions and establish new efficiency standards for a variety of appliances and equipment. Key insertions include definitions for "computer server," "computer server power supply unit," and "state-regulated battery charger systems," which broaden the legislation's scope. The bill also updates specifications for commercial and industrial fans and blowers, faucets, and other water-related appliances, emphasizing the importance of energy and water efficiency.

It mandates that the commissioner of energy resources adopt regulations for minimum efficiency standards, aligning with the latest ENERGY STAR Program Requirements. The bill sets new efficiency standards for household and commercial products, including maximum flow rates for faucets and specific energy consumption limits for water coolers and electric motors. Products manufactured after January 1, 2028, must comply with these standards to be sold or installed in the state, with further regulations for additional products by January 1, 2029.

The legislation outlines testing, certification, and enforcement procedures, requiring manufacturers to certify compliance with the provisions of this chapter to the Modernized Appliance Efficiency Database System, the State Appliance Standards Database, and the Certified Products Directory, or to an approved third-party database. The act will take effect upon passage, aiming to promote ongoing energy and water conservation efforts.
