What鈥檚 the difference between appliance standards and ENERGY STAR?
ENERGY STAR聽is a voluntary labeling program designed to identify and promote energy- and water-efficient products. It is jointly run by the US聽Environmental Protection Agency (EPA) and the US聽Department of Energy (DOE). The appliance standards program, housed in DOE, sets mandatory minimum energy efficiency standards on products manufactured and imported for sale into the US.聽The two programs complement one another: ENERGY STAR聽paves the way for standards by demonstrating that high efficiency products are indeed feasible to manufacture and sell. The market information feeds into standards decisions, often resulting in a standard being set at or near the ENERGY STAR聽levels. Both ENERGY STAR聽and standards are periodically updated, moving efficiency levels up in a step-like progression.
How are standards enforced on the federal level?
Though Congress originally granted DOE the authority to enforce standards in 1975, efficiency standards were not actively enforced for many years. Since 2011, DOE has required聽manufacturers to submit compliance statements and certification reports to the department. DOE issues notices of non-compliance and/or聽penalties for聽improper certification or noncompliance with an applicable standard.聽
