The Federal Energy Management Program (FEMP) provides acquisition guidance for commercial refrigerators and freezers, 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 apply to commercial, food-grade refrigerators and freezers such as:
- Reach-in, roll-in, or pass-through models
- Display refrigerators and merchandisers
- Under-counter and worktop units
- Milk, bottle, and back bar coolers
- Beer-dispensing and direct-draw units
- Glass frosters
- Deep-well and bunker freezers
- Hybrid units.
Horizontal, vertical, and semi-vertical open equipment; deli cases, service over-counter equipment, ice cream freezers, and prep tables; convertible temperature equipment, and laboratory-grade products are excluded. Residential freezers, and residential refrigerators and refrigerator-freezers are covered by separate ENERGY STAR requirements. In the federal sector, commercial refrigerators and freezers are typically used in commercial food service operations like cafeterias, dining halls, snack bars, and officer clubs.
This acquisition guidance was updated in December 2015.
Find Product Efficiency Requirements
The U.S. Environmental Protection Agency (EPA) provides commercial refrigerator and freezer 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-qualified refrigerators and freezers.
Make a Cost-Effective Purchase: Save More than $500 by Buying ENERGY STAR
FEMP has calculated that a required ENERGY STAR-qualified commercial refrigerator saves money if priced no more than $596 above the less efficient model. The best available model saves up to $995. Table 1 compares three types of product purchases 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 Commercial Refrigerator Models|
|Performance||Best Available||ENERGY STAR||Less Efficient|
|Maximum Daily Energy Consumption||1.82 kWh/day||2.71 kWh/day||4.44 kWh/day|
|Annual Energy Use||664 kWh||989 kWh||1,621 kWh|
|Annual Energy Cost||$60||$89||$146|
|Lifetime Energy Cost||$533||$933||$1,529|
|Lifetime Energy Cost Savings||$995||$596||======|
Maximum Daily Energy Consumption (MDEC): Determined in accordance with 10 CFR Part 431 Subpart Q.
Annual Energy Use: Calculated by multiplying the MDEC for each model by 365 days. Assumes a 24-ft3-capacity, vertical solid-door refrigerator operating year round.
Annual Energy Cost: Calculated based on an assumed electricity price of $0.09/kWh, which is the average electricity price at federal facilities throughout the United States.
Lifetime Energy Cost: The sum of the discounted value of annual energy cost and an assumed product life of 12 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 efficiency levels. Federal agencies must purchase products that meet or exceed ENERGY STAR efficiency levels.
Less Efficient Model Column
Calculated based on minimum federal appliance standards for this product category.
