ENERGY STAR® Program Requirements
for Commercial Steam Cookers
Eligibility Criteria
Below is the product specification (Version 1.0) for ENERGY STAR qualified commercial steam cookers. 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 steam cooker and other terms as relevant to
ENERGY STAR.
A.	Steam Cooker: Also referred to as a "compartment steamer," a device with one or more food
steaming compartments in which the energy in the steam is transferred to the food by direct
contact. Models may include countertop models, wall-mounted models and floor-models mounted
on a stand, pedestal or cabinet-style base.
B.	Cooking Energy Efficiency: The quantity of energy input to the food products; expressed as a
percentage of the quantity of energy input to the appliance during the heavy-, medium-, and light-
load tests. For purposes of this specification, heavy-load will be used as a measurement of
energy efficiency.
C.	Heavy (Potato') Load Cooking: The manufacturer's stated capacity of 12 by 20 by 2/4 inch (300 by
500 by 65 mm) perforated hotel pans each filled with 8.0 ± 0.2 lb (3.6 ± 0.1 kg) of fresh, whole, US
No. 1, size B, red potatoes.
D.	Idle Energy Rate: The rate of appliance energy consumption while it is maintaining or holding at a
stabilized operating condition or temperature.
2) Qualifying Products: Any commercial steam cooker that meets the definition in Section 1A is eligible
for the ENERGY STAR. For purposes of this Version 1.0 specification, only 3-, 4-, 5-, and 6-pan
capacity units may qualify for ENERGY STAR.
3) Energy-Efficiency Specifications for Qualifying Products: Only those products listed in Section 2
that meet the criteria presented in Table 1 or 2, below, may qualify as ENERGY STAR:

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
Steam Cookers Qualifying Product Information (QPI) Form.
In performing these tests, partner agrees to measure a model's energy-efficiency using the ASTM
Standard F1484-99, Test Method for the Performance of Steam Cookers.
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 Specification for Commercial
Steam Cookers is effective August 1, 2003.
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. Please note that ENERGY STAR qualification is not automatically granted
for the life of the product model. To carry the ENERGY STAR label, a product model must meet
the ENERGY STAR specification in effect on the model's date of manufacture.
