5.	Provide clear and consistent labeling of ENERGY STAR qualified commercial refrigerators and
freezers. The ENERGY STAR mark must be clearly displayed on the front/inside of the product, on
the product packaging, in product literature (i.e., user manuals, spec sheets, etc.), and on the
manufacturer's Internet site where information about ENERGY STAR qualified models is displayed
Verifying Ongoing Product Qualification	
6.	Participate in third-party verification testing through a Certification Body recognized by EPA for
commercial refrigerators and freezers, providing full cooperation and timely responses. EPA/DOE may
also, at its discretion, conduct tests on products that are referred to as ENERGY STAR qualified.
These products may be obtained on the open market, or voluntarily supplied by Partner at the
government's request.
Providing Information to EPA	
7. Provide unit shipment data or other market indicators to EPA annually to assist with creation of
ENERGY STAR market penetration estimates, as follows:
7.1. Partner must submit the total number of ENERGY STAR qualified commercial refrigerators and
freezers shipped in the calendar year or an equivalent measurement as agreed to in advance by
ENERGY STAR Program Requirements for Commercial Refrigerators and Freezers - Partner Commitments	1

-------
EPA and Partner. Partner shall exclude shipments to organizations that rebrand and resell the
shipments (unaffiliated private labelers).
7.2.	Partner must provide unit shipment data segmented by meaningful product characteristics (e.g.,
type, capacity, presence of additional functions) as prescribed by EPA.
7.3.	Partner must submit unit shipment data for each calendar year to EPA or an EPA-authorized third
party, preferably in electronic format, no later than March 1 of the following year.
Submitted unit shipment data will be used by EPA only for program evaluation purposes and will be
closely controlled. If requested under the Freedom of Information Act (FOIA), EPA will argue that the
data is exempt. Any information used will be masked by EPA so as to protect the confidentiality of the
Partner.
8.	Report to EPA any attempts by recognized laboratories or Certification Bodies (CBs) to influence
testing or certification results or to engage in discriminatory practices.
9.	Notify EPA of a change in the designated responsible party or contacts within 30 days using the My
ENERGY STAR Account tool (MESA) available at www.enerqvstar.gov/mesa.
Performance for Special Distinction	
In order to receive additional recognition and/or support from EPA for its efforts within the Partnership, the
ENERGY STAR Partner may consider the following voluntary measures, and should keep EPA informed
on the progress of these efforts:
¦	Provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase
availability of ENERGY STAR qualified products, and to promote awareness of ENERGY STAR and
its message.
¦	Consider energy efficiency improvements in company facilities and pursue benchmarking buildings
through the ENERGY STAR Buildings program.
¦	Purchase ENERGY STAR qualified products. Revise the company purchasing or procurement
specifications to include ENERGY STAR. Provide procurement officials' contact information to EPA for
periodic updates and coordination. Circulate general ENERGY STAR qualified product information to
employees for use when purchasing products for their homes.
¦	Feature the ENERGY STAR mark(s) on Partner website and other promotional materials. If
information concerning ENERGY STAR is provided on the Partner website as specified by the
ENERGY STAR Web Linking Policy (available in the Partner Resources section of the ENERGY
STAR website), EPA may provide links where appropriate to the Partner website.
¦	Ensure the power management feature is enabled on all ENERGY STAR qualified displays and
computers in use in company facilities, particularly upon installation and after service is performed.
¦	Provide general information about the ENERGY STAR program to employees whose jobs are relevant
to the development, marketing, sales, and service of current ENERGY STAR qualified products.
¦	Provide a simple plan to EPA outlining specific measures Partner plans to undertake beyond the
program requirements listed above. By doing so, EPA may be able to coordinate, and communicate
Partner's activities, provide an EPA representative, or include news about the event in the ENERGY
STAR newsletter, on the ENERGY STAR website, etc. The plan may be as simple as providing a list
of planned activities or milestones of which Partner would like EPA to be aware. For example,
activities may include: (1) increasing the availability of ENERGY STAR qualified products by
converting the entire product line within two years to meet ENERGY STAR guidelines; (2)
demonstrating the economic and environmental benefits of energy efficiency through special in-store
displays twice a year; (3) providing information to users (via the website and user's manual) about
energy-saving features and operating characteristics of ENERGY STAR qualified products; and (4)
building awareness of the ENERGY STAR Partnership and brand identity by collaborating with EPA
on one print advertorial and one live press event.

B.	AHAM Volume: The interior volume (V) of a refrigerator or freezer shall be calculated by AHAM
Standard Household Refrigerators/Household Freezers (ANSI/AHAM HRF-1-2004)2.
C.	Determining Maximum Daily Energy Consumption for Mixed Solid/Glass Door Cabinets: This
section applies to mixed solid/glass door cabinets designed with two or more compartments
contained in a single cabinet with different exterior door types (i.e., one is glass and one is solid)
on the same side of the cabinet. The maximum daily energy consumption (MDEC) of mixed
solid/glass door cabinets shall be the sum of all individual compartment MDEC values. For
purposes of mixed solid/glass door cabinets, compartments are defined by the volume associated
with the different exterior door types. The interior of these compartments may or may not be
physically separated.
The volume of each individual compartment shall be measured, and its MDEC limit determined,
based on the compartment's volume and door type, as listed in Table 1 above. The sum of the
volumes of each compartment shall be equivalent to the total AHAM volume of the cabinet.
Example: Consider a vertically-configured refrigeration cabinet with a total volume of 50 cubic
feet with one glass half door and one solid half door on the same side. The MDEC of the
equipment would be the sum of the MDEC for the two compartments. The requirement used to
calculate the MDEC for each compartment is based on the compartment's volume and door type:
Glass Door MDEC: (25 cu. ft. X 0.140) + 1.050 = 4.55 kWh/day
Solid Door MDEC: (25 cu. ft. X 0.037) + 2.200 = 3.13 kWh/day
MDEC for entire cabinet: 4.55 kWh/day + 3.13 kWh/day = 7.68 kWh/day
