ENERGY STAR® Program Requirements
for Commercial Dishwashers
Draft 1 Partner Commitments
Commitment
The following are the terms of the ENERGY STAR Partnership Agreement as it pertains to the
manufacturing of ENERGY STAR qualified commercial dishwashers. The ENERGY STAR Partner must
adhere to the following program requirements:
•	comply with current ENERGY STAR Eligibility Criteria, defining the performance criteria that must be
met for use of the ENERGY STAR certification mark on commercial dishwashers and specifying the
testing criteria for commercial dishwashers. EPA may, 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 EPA's request;
•	comply with current ENERGY STAR Identity Guidelines, describing how the ENERGY STAR marks
and name may be used. Partner is responsible for adhering to these guidelines and for ensuring that
its authorized representatives, such as advertising agencies, dealers, and distributors, are also in
compliance;
•	qualify at least one ENERGY STAR commercial dishwasher within one year of activating the
commercial dishwashers' portion of the agreement. When Partner qualifies the product, it must meet
the specification (e.g., Tier 1 or 2) in effect at that time;
•	provide clear and consistent labeling of ENERGY STAR qualified commercial dishwashers. The
ENERGY STAR mark must be clearly displayed on the top/front of the product, in product literature
(i.e., user manuals, spec sheets, etc.), on product packaging, and on the manufacturer's Internet site
where information about ENERGY STAR qualified models is displayed;
•	provide to EPA, on an annual basis, an updated list of ENERGY STAR qualifying commercial
dishwasher models. Once the Partner submits its first list of ENERGY STAR qualified commercial
dishwashers, the Partner will be listed as an ENERGY STAR Partner. Partner must provide annual
updates in order to remain on the list of participating product manufacturers;
•	provide to EPA, on an annual basis, unit shipment data or other market indicators to assist in
determining the market penetration of ENERGY STAR. Specifically, Partner must submit the total
number of ENERGY STAR qualified commercial dishwashers shipped (in units by model) or an
equivalent measurement as agreed to in advance by EPA and Partner. Partner is also encouraged
to provide ENERGY STAR qualified unit shipment data segmented by meaningful product
characteristics (e.g., capacity, size, speed, or other as relevant), total unit shipments for each model
in its product line, and percent of total unit shipments that qualify as ENERGY STAR. The data for
each calendar year should be submitted to EPA, preferably in electronic format, no later than the
following March and may be provided directly from the Partner or through a third party. The 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;
•	notify EPA of a change in the designated responsible party or contacts for commercial dishwashers
within 30 days.

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:
•	consider energy efficiency improvements in company facilities and pursue the ENERGY STAR mark
for buildings;
•	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;
•	ensure the power management feature is enabled on all ENERGY STAR qualified monitors 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
product models;
•	feature the ENERGY STAR mark(s) on Partner Web site and in other promotional materials. If
information concerning ENERGY STAR is provided on the Partner Web site as specified by the
ENERGY STAR Web Linking Policy (this document can be found in the Partner Resources section
on the ENERGY STAR Web site at www.enerqvstar.gov). EPA may provide links where appropriate
to the Partner Web site;
•	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, communicate,
and/or promote Partner's activities, provide an EPA representative, or include news about the event
in the ENERGY STAR newsletter, on the ENERGY STAR Web pages, etc. The plan may be as
simple as providing a list of planned activities or planned milestones that Partner would like EPA to
be aware of. For example, activities may include: (1) increase the availability of ENERGY STAR
labeled products by converting the entire product line within two years to meet ENERGY STAR
guidelines; (2) demonstrate the economic and environmental benefits of energy efficiency through
special in-store displays twice a year; (3) provide information to users (via the Web site and user's
manual) about energy-saving features and operating characteristics of ENERGY STAR qualified
products, and (4) build awareness of the ENERGY STAR Partnership and brand identity by
collaborating with EPA on one print advertorial and one live press event;
•	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.

ENERGY STAR® Program Requirements
for Commercial Dishwashers
Draft 1 Eligibility Criteria
Below is the DRAFT 1 product specification for ENERGY STAR qualified commercial dishwashers. A
product must meet all of the identified criteria if it is to earn the ENERGY STAR.
1) Definitions: Below are the definitions of the relevant terms in this document.
A.	Dishwashing Machine: A machine designed to clean and sanitize plates, glasses, cups, bowls,
utensils, and trays by applying sprays of detergent solution (with or without blasting media
granules) and a sanitizing final rinse.
B.	Stationary Rack Dishwasher: A machine in which a rack of dishes remains stationary within the
machine while subjected to sequential wash and rinse sprays. This definition also applies to
machines in which the rack revolves on an axis during the wash and rinse cycles. The following
subcategories of dishwashers are covered by this specification:
•	Under Counter: Similar in design to residential units, these machines are designed to hold a
single rack of soiled wares, which are accessed by opening and lowering a single door. A
revolving wash arm distributes water for both the wash and rinse cycle. A single tank holds
the water and is drained at the end of each cycle. An automatic timer controls each wash
cycle. These machines are typically installed under the food preparation workspace.
•	Door Type: Machines equipped with single or multiple doors that slide vertically to load and
unload dishes. These machines typically come with a single tank for water and detergent,
which are applied evenly to the dishware via two revolving spray arms, one above and one
below the rack(s). For purposes of this specification, only single tank door type machines can
qualify as ENERGY STAR.
C.	Single Tank Conveyor Dishwasher: A warewashing machine that employs a conveyor or similar
mechanism to carry dishes through a series of wash and rinse sprays within the machine.
Specifically, a single tank conveyor machine has a tank for wash water followed by a final
sanitizing rinse and does not have a pumped rinse tank. This type of machine may include a pre-
washing section ahead of the washing section and an auxiliary rinse section between the power
rinse and final rinse sections.
D.	Hot Water Sanitizing (High Temp) Machine: A warewashing machine that applies hot water to the
surfaces of dishes to achieve sanitization.
E.	Chemical Sanitizing (Low Temp) Machine: A warewashing machine that applies a chemical
sanitizing solution to the surfaces of wares to achieve sanitization.
Note: The definitions provided above were taken from various sources including the NSF
International Standard for Food Equipment, Glossary of Food Equipment Terminology, NSF/ANSI
170 - 2005, Section 3: Definitions. Stakeholders are encouraged to provide comments as to
whether these definitions accurately represent the various product types covered by this
specification and if there are other terms that need clarification and should be included in this list.
2) Qualifying Products: Commercial dishwashers must meet the definitions provided in Section 1, above,
to be eligible for ENERGY STAR.

Note: In determining which categories to include in this specification EPA chose the most
prevalent and simplest designs: under counter; single tank, single rack door type; and single tank
conveyor. EPA may consider other product categories given manufacturer interest, prevalence in
the marketplace, and data availability.
3) Efficiency Requirements for Qualifying Products: Commercial dishwashers must meet the
requirements provided below in Table 1 to qualify as ENERGY STAR.

Note: The primary objective of ENERGY STAR is to recognize the most energy-efficient products
in the marketplace. In developing a specification, EPA considers the following criteria:
•	Significant energy and/or water savings can be realized on a national basis
•	Product performance is maintained or enhanced with increased efficiency
•	Purchase of high efficiency product will be cost-effective
•	Energy and/or water efficiency can be achieved through several technology options; at least
one of which is non-proprietary
•	Product energy and/or water consumption and performance can be measured and verified
with testing
•	Labeling would effectively differentiate products and be visible for purchasers
It is not EPA's intention to design a specification that will allow every model to qualify. The
performance levels proposed in Table 1 are based on the NSF database and represent
approximately the top 25% of models currently available on the market. EPA hopes that over
time, the percentage of qualified products will increase as ENERGY STAR penetrates the
market. The calculations provided above were taken from the NSF/ANSI 2-2003 Standard to
determine gallons/rack for each product type covered by this specification.
4) Test Criteria: Manufacturers are required to perform tests and self-certify those product models that
meet the ENERGY STAR guidelines. The test results must be reported to EPA using the Commercial
Dishwasher Qualifying Product Information (QPI) Form.
In performing these tests, partner agrees to use the NSF/ANSI 3-2003 Standard, Commercial
Warewashing Equipment.
Note: For this Draft 1 specification EPA is referencing the most recent NSF International Standard for
measuring commercial dishwasher performance. The NSF Standard is currently recognized and used
by manufacturers for purposes of comparing and marketing their commercial dishwasher models.
Although the NSF Standard lacks any direct measurement of energy consumption there is a correlation
between the water used in the rinse cycle and the energy used to heat that water.
There are test procedures available that do take into consideration the energy used during the
dishwashing cycle, however these test methods are not widely used by commercial dishwasher
manufacturers. These include the American Society for Testing and Materials' (ASTM) Standard Test
Methods for the Hot Water Sanitizing Door Type Dish Machines (F1696) and Conveyor Type Dish
Machines (F1920). These test methods are primarily intended to measure and document the energy
and water consumption (gallons/rack) of the dishwashers under standardized operating conditions
(preheat, idle and washing). Since industry is not currently using these test procedures no published
data exists in order to use it for purposes of this specification. Furthermore, ASTM test methods only
exist for high temp conveyor and door type dishwashers. There are no ASTM test methods available for
chemical sanitizing door type and conveyor machines, nor is there one for undercounter machines (high
or low temp).
Therefore, EPA is proposing to use the NSF Standard for this first version of the specification but
continues to be interested in updating and using these ASTM test procedures to measure direct energy
use in the future and encourages manufacturers to be part of this process.

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 Commercial Dishwasher
Specification shall go into effect on TBD.
Note: Typically, EPA looks to announce a new ENERGY STAR specification in conjunction with
an industry trade show or conference. It is EPA's hope that this specification can be finalized by
the end of this year. Given this tentative timeline, stakeholders are encouraged to provide EPA
with a list of potential venues where the ENERGY STAR Commercial Dishwasher program could
be launched. Manufacturers should also comment on the length of time needed to allow for
ENERGY STAR qualified models to be available at the time of the announcement.
6) Future Specification Revisions: ENERGY STAR reserves the right to change the specification should
technological and/or market changes affect its usefulness to consumers, industry, or the environment.
In keeping with current policy, revisions to the specification are arrived at through industry
discussions. In the event of a specification revision, please note that the ENERGY STAR qualification
is not automatically granted for the life of a product model. To qualify with the energy efficiency
criteria of ENERGY STAR, a product model must meet the ENERGY STAR specification in effect on
the date of manufacture.
