More Stringent Energy Efficiency Standards for Fluorescent Lamps
06 February 2015
The Department of Energy has issued a final rule establishing stricter minimum energy efficiency standards for general service fluorescent lamps. The rule will enter into force on 27 March and compliance with the new standards will be required from 26 January 2018. However, the DOE has declined to issue amended standards for incandescent reflector lamps.
The Energy Policy and Conservation Act of 1975 prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including general service fluorescent lamps and incandescent reflector lamps. The EPCA also requires the DOE to determine whether more stringent standards would be technologically feasible and economically justified and would save a significant amount of energy. In its final rule, the DOE is adopting more stringent standards for general service fluorescent lamps because it has determined that such standards would result in significant conservation of energy and are technologically feasible and economically justified. On the other hand, the agency concluded that amending the energy conservation standards for incandescent reflector lamps would not be economically justified.
General service fluorescent lamps subject to the new standards include 4-foot medium bipin lamps (0.8 or 3.8 percent increase in efficiency from current standards, depending on their correlated colour temperature), 2-foot u-shaped lamps (1.2 or 2.8 increase), 8-foot slimline lamps (no increase), 8-foot recessed double contact high output lamps (no increase), 4-foot miniature bipin standard output lamps (10.2 or 10.5 percent increase) and 4-foot miniature bipin high output lamps (6.8 or 8.8 percent increase).
The energy savings over the entire lifetime of general service fluorescent lamps installed during the 30-year period that begins in the year of compliance with the amended standards (2018–2047), in comparison to the base case without the amended standards, amount to 2.5 quadrillion Btu. This represents a savings of 7.1 percent relative to the energy use of this product in the base case without the amended standards. The cumulative net present value of total consumer costs and savings of these standards for subject lamps ranges from US$2.0 billion (at a seven percent discount rate) to US$5.5 billion (at a three percent discount rate). This NPV expresses the estimated total value of future operating-cost savings minus the estimated increased product costs for products purchased during 2018–2047.
