The Federal Energy Management Program (FEMP) provides acquisition guidance for air-cooled ice machines, a product category covered by ENERGY STAR efficiency requirements. Federal laws and requirements mandate that agencies purchase ENERGY STAR-qualified products or FEMP-designated products in all product categories covered by these programs and in any acquisition actions that are not specifically exempted by law.
FEMP’s acquisition guidance and associated ENERGY STAR efficiency requirements for air-cooled ice machines applies to self-contained, remote-condensing, or ice-making head type machines that use either the continuous or batch ice making process. Air-cooled remote condensing units connected to rack compressors, ice and water dispensers, and water-cooled ice machines are excluded from this ENERGY STAR specification.
Water-cooled ice machines are covered by separate FEMP-designated efficiency requirements and acquisition guidance.
In the federal sector, ice machines are typically used in commercial food service operations like cafeterias in General Services Administration (GSA) buildings, kitchens in penitentiaries, and commissaries on military bases. They are also used for patient care in Veterans Affairs medical centers and hospitals operated by the U.S. Department of Health and Human Services.
This acquisition guidance was updated in December 2015.
Find Product Efficiency Requirements
The U.S. Environmental Protection Agency (EPA) provides ice machine efficiency levels and product specification information on its ENERGY STAR website. Manufacturers meeting these requirements are allowed to display the ENERGY STAR label on complying models. Get a list of ENERGY STAR certified ice machines.
Make a Cost-Effective Purchase: Save More than $1,600 by Buying ENERGY STAR
FEMP has calculated that the required ENERGY STAR-qualified air-cooled ice machine saves money if priced no more than $1,620 above the less efficient model. The best available model saves up to $1,740. Table 1 compares three types of air-cooled ice machines and calculates the lifetime cost savings of purchasing efficient models. Federal purchasers can assume products that meet ENERGY STAR efficiency requirements are life cycle cost-effective.
|Table 1. Lifetime Savings for Efficient Air-Cooled Ice Machine Models|
|Performance||Best Available||ENERGY STAR||Less Efficient|
|Annual Ice Production||100,000 lb||100,000 lb||100,000 lb|
|Energy Consumption Rate||6.8 kWh/100 lb||7.0 kWh/100 lb||9.8 kWh/100 lb|
|Annual Energy Use||6,800 kWh/year||7,000 kWh/year||9,800 kWh/year|
|Annual Energy Cost||$612||$630||$882|
|Lifetime Energy Cost||$3,940||$4,060||$5,680|
|Lifetime Energy Cost Savings||$1,740||$1,620||======|
Annual Ice Production: Assumes an air-cooled ice machine producing 400 pounds of ice per day, 250 days per year.
Energy Consumption Rate: A measure of kilowatt hours used per 100 pounds of ice made.
Annual Energy Use: Based on the federal standard for this product category.
Annual Energy Cost: Calculated based on an assumed electricity price of $0.09/kWh, which is the average electricity price at federal facilities.
Lifetime Energy Cost: The sum of the discounted values of annual energy cost with an average air-cooled ice machine life of 7 years. Future electricity price trends and a 3% discount rate are from Energy Price Indices and Discount Factors for Life-Cycle Cost Analysis – 2015: Annual Supplement to NIST Handbook 135 and NBS Special Publication 709 (NISTIR 85-3273-30).
Lifetime Energy Cost Savings: The difference between the lifetime energy cost of the less efficient model and the lifetime energy cost of the ENERGY STAR model or best available model.
Best Available Model Column
Calculated based on the ENERGY STAR List of Qualified Products. More efficient models may be introduced to the market after FEMP's acquisition guidance is posted.
ENERGY STAR Model Column
Calculated based on current ENERGY STAR eligibility criteria. Federal agencies must purchase products that meet or exceed ENERGY STAR efficiency levels.
Less Efficient Model Column
Calculated based on the performance of products commonly used in commercial kitchens.
