UL Energy Efficiency Certification, also known as UL 1930, is a voluntary certification program that helps consumers identify energy-efficient products, such as appliances, lighting, HVAC, electronics and building materials. It is administered by Underwriters Laboratories (UL), a global independent safety science company. To be certified with the UL Energy Efficiency Certification, a product must meet strict energy efficiency standards. The standards vary depending on the type of product, but they are designed to ensure that the product uses less energy than similar products on the market. Products that achieve UL Energy Efficiency Certification are eligible to use the UL Energy Efficiency Mark on their packaging and marketing materials.
