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, 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 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.

Product Specification for Commercial Griddles
Eligibility Criteria
DRAFT Version 1.1
Following is the Version 1.1 ENERGY STAR product specification for commercial griddles. A product
shall 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. Single-Sided Commercial Griddle: A commercial appliance designed for cooking food in oil or its
own juices by direct contact with either a flat, smooth, hot surface (e.g., polished steel or chrome
plate) or a hot channeled cooking surface (e.g., polished steel or chrome 1/2-inch grooved plate)
where plate temperature is thermostatically controlled.
B. Double-Sided Commercial Griddle: A commercial appliance designed for cooking food in oil or its
own juices by direct contact with two hot surfaces where temperature is thermostatically
controlled. A double-sided griddle has hinged upper griddle plates (platens) that swing down over
the food, thereby cooking the food from both sides at once.
C. Product Family: Several models are offered within one product line that may differ in regards to
energy consumption but are based on the same engineering design, differing only in regards to
griddle size and/or griddle plate option.
D. Fry-Top Range: A multi-purpose appliance used for surface cooking by direct contact with a
heated plate, and may also function as a device for roasting, broiling, grilling or any combination of
these methods. A fry-top range may have an oven located beneath the cooktop or shelving or may
be mounted on top of a refrigerated base.
E. Manual Control: Infinite-control knob to regulate the input of each burner or element. Manual
controls are calibrated in terms of the percentage of input, as the control does not generally sense
the temperature of the cooking surface.
F. Thermostatic Control: Simple temperature-feedback control that regulates the heaters based on
griddle plate temperature. Thermostatic controls have the potential to sense the presence of
cooking loads and offer better response and faster recovery when a load of fresh product is
placed on the cooking surface.
G. Cooking Energy Efficiency: The ratio of energy absorbed by the food product to the total energy
supplied to the griddle during cooking.
H. Idle Energy Rate: The rate of griddle energy consumption while it is maintaining or holding at a
stabilized operating condition or temperature. Also called standby energy rate. For the purposes of
this specification, the idle rate is normalized based on the area of the (bottom) cooking surface.
A. Included Products: Products that meet the definitions of a Single-Sided and Double-Sided Griddle
as specified herein are eligible for ENERGY STAR qualification, with the exception of products
listed in Section 2.B
B. Excluded Products: Griddles with manual controls and fry-top ranges, as defined in Section 1
above, are not eligible for ENERGY STAR under this specification.

C. Additional Qualification Requirements for Double-Sided Griddles: Double-Sided Griddles may
qualify for ENERGY STAR under the following conditions:
a. Integrated, double-sided units with full top platen (> 90% coverage from side to side) shall be
tested and evaluated for qualification as a double-sided griddle.
b. Integrated, double-sided unit with partial platen(s) (< 90% coverage from side to side) shall
be tested and evaluated for qualification as a single sided griddle (with top up and turned off).
c. Double-sided units with add-on top platens (full or partial) shall be tested and evaluated for
qualification as a single sided griddle (with top up and turned off).
Note: Integrated refers to double-sided griddles designed to operate only while using a top platen.
Add-on top platens are sold to end users as options to a single sided griddle and can be added on
to a base model at the factory level or installed in the field.
D. Significant Digits and Rounding:
a. All calculations shall be carried out with actual measured or observed values. Only the final
result of a calculation shall be rounded. Calculated results shall be rounded to the nearest
significant figure as expressed in the corresponding specification limit.
b. Unless otherwise specified, compliance with specification limits shall be evaluated using exact
values without any benefit from rounding.
4) Test Requirements:
A. Representative Models shall be selected for testing per the following requirements:
a. For qualification of an individual product model, the representative model shall be equivalent to
that which is intended to be marketed and labeled as ENERGY STAR.
b. For qualification of a product family, the 3 ft. model within the product family shall serve as the
representative model. If product family includes units smaller than 3 ft., each additional unit
shall be tested and qualified separately from its product family. If smaller unit does not qualify,
then it cannot be part of the qualifying product family.
B. Each individual griddle plate option offered by the manufacturer for any one model shall be tested
for ENERGY STAR qualification.
C. When testing commercial griddles, the following test methods shall be used to determine
ENERGY STAR qualification:

6) Future Specification Revisions: EPA 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 ENERGY STAR qualification is
not automatically granted for the life of a product model.
A. Tier 2 Normalized Idle Energy Rate: The Tier 2 normalized idle energy rate for electric griddles will
be reviewed prior to January 1, 2011 to ensure it is appropriate for the marketplace.
B. Partial Platen Performance: At the time of developing this specification, the ASTM F1605 test
method for measuring double-sided griddle performance could not be applied to units with partial
platens. However, there is industry interest to revise the test method to more appropriately
measure cooking energy efficiency and idle energy rate of double-sided griddles with partial
platens. If new ASTM testing guidelines are developed for partial platen configurations, EPA will
require that the new test method be applied to these product types for purposes of ENERGY
STAR qualification.
