Current Criteria—Effective August 15, 2003
Maximum Idle Energy Rate = 40 watts/ft3

The maximum idle energy rate is based on the “idle energy rate—dry test” in ASTM F2140-01. Interior volume (ft3) of each qualifying model must be measured according to the protocol provided below.

Measuring Interior Volume: Commercial hot food holding cabinet interior volume shall be calculated using straight-line segments following the gross interior dimensions of the appliance and using the following equation: interior height x interior width x interior depth. Interior volume shall not account for racks, air plenums or other interior parts.

Commercial Ice Machines
The Vendor Must:
Provide commercial ice machines that earn the ENERGY STAR and meet the ENERGY STAR specifications for energy and water efficiency as outlined below. Ice machines that use water-cooled technology as well as flake and nugget ice machines are not eligible for ENERGY STAR under Version 1.0. EPA intends to include flake and nugget ice machines once a test standard is made available and a robust database is established that may be used to derive performance requirements. The vendor is encouraged to visit energystar.gov for complete product specifications and an updated list of qualifying products.

Efficiency Requirements for Commercial Ice Machines—Effective January 1, 2008
Equipment Type Harvest Rate, H

Provide commercial steam cookers that earn the ENERGY STAR and meet the ENERGY STAR specifications for energy efficiency as outlined below. Only 3-, 4-, 5-, and 6-pan capacity units can qualify for ENERGY STAR. Models may include countertop models, wall-mounted models and floor-models mounted. The vendor is encouraged to visit energystar.gov for complete product specifications and an updated list of qualifying products.

Energy Efficiency Requirements for Electric Steam Cookers—Effective August 1, 2003
Pan Capacity Cooking Energy Efficiency* Idle Rate** (watts)
3-pan 50% 400
4-pan 50% 530
5-pan 50% 670
6-pan 50% 800

3-pan 38% 6,250
4-pan 38% 8,350
5-pan 38% 10,400
6-pan 38% 12,500

Vending Machines
The Vendor Must:
Provide vending machines that earn the ENERGY STAR and meet the ENERGY STAR specifications for energy efficiency as outlined below. The vendor is encouraged to visit energystar.gov for complete product specifications and an updated list of qualifying products.

Energy Consumption
Current Criteria—Effective April 1, 2004 New Criteria—Effective January 1, 2007
Y = 0.55 [8.66 + (0.009 x C)] Y = 0.45 [8.66 + (0.009 x C)]
Y = 24 hr energy consumption (kWh/day) after the machine has stabilized
C = vendible capacity

Low Power Mode: In addition to meeting the 24-hour energy consumption requirements listed above, qualifying models shall come equipped with hard wired controls and/or software capable of automatically placing the machine into a low power mode during periods of extended inactivity while still connected to its power source to facilitate the saving of additional energy, where appropriate. The machine shall be capable of operating in each of the low power mode states described below:

1. Lighting low power state – lights off for an extended period of time.
2. Refrigeration low power state – the average beverage temperature is allowed to rise above 40°F for an extended period of time.
3. Whole machine low power state – the lights are off and the refrigeration operates in its low power state.

In addition, the machine shall be capable of automatically returning itself back to its normal operating conditions at the conclusion of the inactivity period. The low power mode-related controls/software shall be capable of on-site adjustments by the vending operator or machine owner.

Note: EPA’s goal in including these low power mode requirements is to ensure that existing machine software capabilities are available and may be used to their fullest potential based on the individual requirements of the host site. However, machines that are vending temperature sensitive product, such as milk, must not have the refrigeration low power state enabled on site by the vending operator or machine owner due to the risk of product spoilage.
