1. E NERGY S TAR ® Preliminary Draft Specification for Vending Machines October 22, 2002 Rachel Schmeltz, EPA schmeltz.rachel@epa.gov

2. Definitions Define the product and other terms relevant to testing or efficiency requirements: –Refrigerated Beverage Vending Machine –Machine or Product Capacity –Low Power Mode Questions for discussion: (1) Are there other definitions that should be included? (2) Are current definitions accurate?

3. Qualifying Products Product sub categories that may qualify under the specification –Closed-front and live display refrigerated beverage vending machine models Question for discussion: (1) Should additional product categories be included, e.g. glass front models?

4. Energy-Efficiency Specifications Qualifying products must meet performance requirements – 2 parts (1) Energy Consumption –Energy consumption less than or equal to value obtained from the following equation: Y = 0.55 (8.66 + 0.009 x C) Y is the 24 hr consumption (kWh/day) C is the machine capacity expressed in maximum number of 12-oz cans

5. Energy-Efficiency Specifications (2) Low Power Mode – hard wired controls and software capable of automatically placing machine in low power mode during extended periods of inactivity: –Reduce lights to 20% or less of default lighting levels –Allow beverage temp to rise to 50 degrees F –Return machine to normal operating conditions at conclusion of inactivity –Allow on-site adjustment by host for site-specific conditions

6. Energy-Efficiency Specifications Rationale: Based on familiar CSA standard Based on limited test data; EPA is interested in gathering more data Energy-efficient lighting is already being implemented which increases efficiency by about 1.1 kWh/day Specification goes beyond lighting

7. Energy-Efficiency Specifications Questions for Discussion: (1) Should specification level be based on on CSA standard? (2) Is the specification level reasonable; does it represent about top 25% of market; if not, is additional data available? (3) Are low power mode parameters acceptable?

8. Test Criteria Testing is self-certified Testing follows ASHRAE Standard 32.1-1997 procedure Manufacturers will use Qualified Product Information (QPI) form to report products and testing results (see example)

9. Effective Date The date that manufacturers may begin to qualify and label products –Will be coordinated with product launch to ensure partner participation and product availability Questions for Discussion: (1) How much time is needed to test, qualify, and label products once a specification is finalized? (2) What event could be used to launch an E NERGY S TAR specification?

10. Future Specification Revisions If technology and market changes affect the usefulness of the specification to consumers, industry or the environment; EPA looks to revise specification –May have multiple tiers –EPA will work with industry to revise specification E NERGY S TAR qualification is not automatically granted for the life of the product model

11. Other Issues for Discussion Product Labeling Installed Base/Retrofit Options Others?
