Yes; this type of refrigerator-freezer is eligible for ENERGY STAR qualification under the ENERGY STAR Residential Refrigerators and Freezers V4.1 specification. The V4.1 specification references 18 product classes established by the U.S. Department of Energy (DOE) Code of Federal Regulations (CFR) for purposes of federal energy conservation standards. At the time these product classes were established, bottom-freezers with through-the-door ice were not available on the market and therefore, this product type is not listed in the specification. DOE’s Office of Hearings and Appeals has granted a number of exceptions to manufacturers for refrigerator-freezer products with bottom freezers and through-the-door ice (future DOE product class 5a*), specifying the energy standard equation for maximum energy use (kWh/year) as: 5.0*AV+539.0.
For ENERGY STAR qualification, these products must use 20% less energy than the federal energy conservation standard, consistent with V4.1 requirements for all refrigerator-freezers.
For ENERGY STAR qualification, certification bodies (CBs) should ensure that the unit has obtained the necessary exception from DOE and that the unit’s annual energy use is less than or equal to: 4.00*AV+431.2.
*DOE's future product class 5a comes into effect with the amended energy conservation standards. Manufacturers must comply with these requirements beginning September 15, 2014.
