What ENERGY STAR Purchasing & Procurement resources does EPA offer?

ENERGY STAR Purchasing & Procurement resources include lists of qualifying products, key product criteria, drop-in procurement language and savings calculators. Organizations can use these resources to facilitate the procurement of energy-efficient ENERGY STAR products and prevent greenhouse gas emissions.

Sample Procurement Language

The following is an example of language you may wish to require in your upcoming contract:

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.
