ENERGY STAR Version 2.0 Program Requirements for Refrigerated Beverage Vending Machines ------- K. UL Standard 541: UL Safety Standard for Refrigerated Vending Machines. 2) Qualifying Products: In order to qualify for the ENERGY STAR, a refrigerated beverage vending machine must meet the definition in Section 1 A. All qualifying models must also meet the performance requirements provided in Section 3, below, at the time of manufacturing or rebuilding. 3) Energy-Efficiency Specifications for Qualifying Products: Only those products listed in Section 2 that meet both criteria A and B provided below may qualify as ENERGY STAR. A. Energy Consumption: Qualifying models shall consume equal to or less energy in a 24-hr period than the values obtained from the equations3, shown below. Effective dates for Tier I and Tier II are provided in Section 6 of this specification. Tier I Y = 0.55 [8.66 + (0.009 xC)] Tier II Y = 0.45 [8.66 + (0.009 xC)] Where: Y = 24 hr energy consumption (kWh/day) after the machine has stabilized C = vendible capacity Example: Under Tier I, a 650-can capacity machine may consume no more than 7.9805, or 7.98 kWh/day (rounded). Under Tier II, a 650-can may consume no more than 6.5295 or 6.53 kWh/day (rounded). B. Low Power Mode: In addition to meeting the 24-hour energy consumption requirements in Section 3A, qualifying models shall come equipped with hard wired controls and/or software capable of 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 at least one 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 to 40°F or higher 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. While only one of the above low power mode state is required, EPA encourages new machine manufacturers to continue to include all of the low power mode options in equipment designs and partners that are rebuilding machines to seek out new technologies that might help to achieve this goal as well. In addition, the machine shall be capable of 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 unless the low power controlling device is already pre-programmed when installed into the machine. EPA encourages partners to train vending machine installers to provide information to host sites on the low power mode capabilities of their machines so that these capabilities may be enabled as desired by the host site. 3 The energy consumption equation is based on CAN/CSA C804-96 Energy Performance of Vending Machines (for Machine Type A). ENERGY STAR Version 2.0 Program Requirements for Refrigerated Beverage Vending Machines ------- 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. 4) Test Criteria: ENERGY STAR Partners are required to perform tests, according to the requirements included in this Version 2.0 specification, and then submit qualifying model information to EPA for approval. A. In performing these tests, Partner agrees to measure a model's daily energy consumption according to ASHRAE Standard 32.1-2004, Methods of Testing for Rating Vending Machines for Bottled, Canned, and Other Sealed Beverages, using the test conditions provided in Section 6 of the standard: 1. Machines marked "For Indoor Use Only" must be tested at 75+2 °F (23.9+1 °C); 45+5% relative humidity; and 36+1 °F (2.2+0.5 °C) average beverage temperature throughout the test. 2. Machines marked "Suitable for Outdoor Use" or "Suitable For Protected Locations" must be tested at 90+2 °F (32.2+1 °C); 65+5% relative humidity; and 36+1 °F (2.2+0.5 °C) average beverage temperature throughout the test. B. Test results must be reported to EPA using the Refrigerated Beverage Vending Machine Qualifying Product Information (QPI) Version 2.0 form. 5) Additional Qualification and Certification Procedures for Rebuilt Vending Machines: Each rebuilt vending machine model number should be distinct and representative of a particular model and rebuilding kit combination that has been tested and qualified for ENERGY STAR. For example, the Partner may submit multiple component and/or rebuilding kit options for one vending machine model but each combination must be supported by individual test results and represented by separate model numbers. EPA reserves the right to request additional information on ENERGY STAR qualified rebuilt machines should an issue arise regarding their performance and qualification. When qualifying and reporting rebuilt machines: • Partner will be responsible for identifying and testing each component and/or rebuilding kit within each machine model to determine which combination(s) will meet the ENERGY STAR energy- efficiency specifications. It is also the responsibility of the Partner to verify UL or equivalent safety requirements and that the components are Listed, Recognized, Classified, etc., as applicable for each component. • Partner must test a representative machine for each model and component combination to ASHRAE Standard 32.1-2004 and report the results to EPA using the Refrigerated Beverage Vending Machines QPI Version 2.0 form for review. Once EPA has approved the rebuilt model, the Partner may begin remanufacturing machines with the energy-saving components and/or "kits" and labeling the resulting rebuilt models as ENERGY STAR. • When rebuilding machines for ENERGY STAR qualification, the Partner must use only those components that have been tested and approved for use in specific ENERGY STAR configurations, as identified by the Partner; and meet the applicable UL or equivalent safety requirements, including Listed, Recognized, Classified, etc. as applicable. In addition, it is the responsibility of the Partner to ensure that installation is performed according to the appropriate machine guidelines. ENERGY STAR Version 2.0 Program Requirements for Refrigerated Beverage Vending Machines ------- 6) Effective Date: The date that manufacturers may begin to qualify machines as ENERGY STAR will be defined as the effective date of the agreement. A. Tier I - The first phase, Tier I, shall go into effect on April 1, 2004 and conclude on June 30, 2007. Rebuilt Machines: Effective August 31, 2006 rebuilt machines may qualify as ENERGY STAR. B. Tier II - The second phase of this specification, Tier II, shall commence on July 1, 2007. All products, including models originally qualified under Tier I, with a date of manufacture or rebuild on or after July 1, 2007, must meet Tier II requirements in order to bear the ENERGY STAR on the product or in product literature. 7) 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. In the event of a specification revision, please note that ENERGY STAR qualification is not automatically granted for the life of a 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. The date of manufacture is specific to each unit and is the date by which a unit is considered to be completely assembled.
