ENERGY STAR® Program Requirements
for Commercial Solid Door Refrigerators
and Freezers
Eligibility Criteria
Below is the product specification (Version 1.1) for ENERGY STAR qualified commercial solid door
refrigerators and freezers. A product must meet all of the identified criteria if it is to be labeled as
ENERGY STAR by its manufacturer.
1)	Definitions: Below is a brief description of a commercial solid door refrigerator and commercial solid
door freezer and other terms relevant to ENERGY STAR.
A.	Commercial Refrigerator: A cabinet designed for storing food or other perishable items at
temperatures above 32 degrees Fahrenheit (F) but no greater than 40 degrees F.
B.	Commercial Freezer: A cabinet designed for storing food or other perishable items at
temperatures of 0 degrees F or below.
C.	Commercial Refrigerator-Freezer: A cabinet with two or more compartments, at least one of
which is designed for storing food or other perishable items at temperatures above 32 degrees F but
no greater than 40 degrees F and at least one of which is designed for storing food or other
perishable items at temperatures of 0 degrees F or below.
D.	Commercial Ice Cream Freezer: A cabinet designed for storing food or other perishable items at
temperatures of-5 degrees F or below.
E.	Commercial Refrigeration Cabinet: A refrigerator, freezer, or refrigerator-freezer for storing food
products or other perishable items at specified temperatures and designed for use by commercial or
institutional facilities.
F.	Self-contained Refrigeration Cabinet: A refrigerator, freezer, or refrigerator-freezer which has the
condensing unit built into the cabinet.
G.	Energy Consumption: The energy required to maintain the contents at a specified temperature
for a 24-hour period.
H.	Integrated Average Product Temperature: The integrated average of all test package
temperatures, recorded at 15-minute intervals, as determined using the test method prescribed in
Section 4, Test Criteria.
I.	ASHRAE: American Society of Heating, Refrigerating, and Air Conditioning Engineers, Inc.
J. Worktop Surface: A solid working surface and backsplash. The working surface may be a
cutting board, a stainless steel work surface, or a stone slab.
2)	Qualifying Products: For the purposes of ENERGY STAR, the following types of commercial solid
door refrigerators, freezers, and refrigerator-freezers may qualify:
A. Reach-in Cabinet: An upright commercial, self-contained refrigeration cabinet with hinged, solid
doors but excluding undercounter, roll-in, roll-through, or pass-through cabinets.

-------
B.	Undercounter Cabinet: An upright commercial, self-contained refrigeration cabinet with or without
a worktop surface (see definition in Section 1) which has hinged, solid doors. In the case where the
unit does not have a worktop surface, the unit is intended for installation under a counter. In the case
where the unit has a worktop surface, this surface may not add to the total energy consumption of the
unit. Preparation tables are not eligible for ENERGY STAR qualification under this specification.
C.	Roll-in or Roll-through Cabinet: An upright, self-contained commercial refrigeration cabinet with
hinged, solid doors that allows wheeled racks of product to be rolled into or through the refrigerator or
freezer.
D.	Pass-through Cabinet: An upright commercial, self-contained refrigeration cabinet with hinged,
solid doors on both the front and rear of the refrigerator or freezer.
3) Energy-Efficiency Specifications for Qualifying Products: Only those products listed in Section 2 that
also meet the specifications listed in Table 1 below, may qualify as ENERGY STAR.
Table 1: Specifications for ENERGY STAR Qualified Commercial Solid Door
Refrigerators and Freezers
Product Type
Energy Consumption Under Test
Conditions
Refrigerators
< 0.10V + 2.04 kW-hours/day
Freezers
< 0.40V + 1.38 kW-hours/day
Refrigerator-Freezers
< 0.27AV - 0.71 kW-hours/day
Ice Cream Freezers
< 0.39V + 0.82 kW-hours/day
Note: V = Internal volume in ft3
AV = Adjusted volume = (1.63 x freezer volume in ft3) + refrigerator volume in ft3
4)	Test Criteria: Manufacturers are required to perform tests to self-certify those product models that
meet the ENERGY STAR guidelines. The test results must be reported to EPA using the Commercial
Solid Door Refrigerator and Freezer Qualifying Product Form.
In performing these tests, manufacturers must use ASHRAE Standard 72-2005, "Method of Testing
Commercial Refrigerators and Freezers," to measure the daily energy consumption of commercial
solid door refrigerators and freezers with the following temperature specifications:
Product Type:	Integrated average product temperature:
Commercial solid-door refrigerator	38 degrees ± 2 degrees F
Commercial solid-door freezer	0 degrees ± 2 degrees F
Commercial ice cream cabinet	-5 degrees ± 2 degrees F
5)	Effective Date: The date that manufacturers may begin to qualify products as ENERGY STAR will be
defined as the effective date of the agreement. The ENERGY STAR for Commercial Solid Door
Refrigerators and Freezers Specification (Version 1.1) is effective on September 1, 2001.
6)	Future Specification Revisions: ENERGY STAR reserves the right to revise the specifications should
technological and/or market changes affect its usefulness to purchasers, industry, or the environment.
In keeping with current policy, revisions to the specification are arrived at through discussions with
industry.
