Annual Energy Use: Assumed 2,000 operating hours per year for 23 years.
Annual Energy Cost: Calculated based on an assumed electricity price of 8.6¢/kWh, which is the average electricity price at federal facilities in the United States.
Lifetime Energy Cost: Future electricity price trends and a 3% discount rate are from the Annual Supplement to NIST Handbook 135 and NBS Special Publication 709, Energy Price Indices and Discount Factors for Life Cycle Cost Analysis – 2022 (NISTIR 85-3273-37 update 1).
Lifetime Energy Cost Savings: The difference between the lifetime energy cost of the less efficient model and the lifetime energy cost of the required model or best available model.
Calculated based on highest efficiency model identified in publicly provided manufacturer data as of June 2022. More efficient models may be introduced to the market after FEMP's acquisition guidance is posted.
Calculated based on FEMP-designated efficiency requirements. Federal agencies must purchase products that meet or exceed FEMP-designated efficiency levels.
Calculated based on median efficiency of models identified in publicly provided manufacturer data as of June 2022.
