Purchasing Energy-Efficient Refrigerated Beverage Vending Machines

The Federal Energy Management Program (FEMP) provides acquisition guidance for refrigerated beverage vending machines, a product category covered by ENERGY STAR efficiency requirements. Federal laws and requirements mandate that agencies purchase ENERGY STAR-qualified products or FEMP-designated products in all product categories covered by these programs and in any acquisition actions that are not specifically exempted by law.

FEMP’s acquisition guidance and associated ENERGY STAR efficiency requirements apply to new and remanufactured refrigerated beverage vending machines. Refrigerated food vending machines and large refreshment centers with refrigerated compartments are excluded.

In the federal sector, vending machines are primarily common in snack areas, recreational areas or kitchenettes, or near dining areas of many facilities. Some buildings even have "vending areas" off the main corridors that contain many different types of vending machines. It is quite common for vending machines to be provided by a service vendor. See the Refrigerated Beverage Vending Machine Service Contracts section for more information about including efficiency requirements in service contracts.

This acquisition guidance was updated in December 2023.

Find Product Efficiency Requirements

The U.S. Environmental Protection Agency (EPA) provides vending machine efficiency levels and product specification information on its ENERGY STAR website. Manufacturers meeting these requirements are allowed to display the ENERGY STAR label on complying models. Get a list of ENERGY STAR-qualified vending machines.

Make a Cost-Effective Purchase: Save $97 by Buying ENERGY STAR

FEMP has calculated that the required ENERGY STAR-qualified refrigerated beverage vending machine saves money if priced no more than $97 (in 2022 dollars) above the less efficient model. The best available model saves up to $264. Table 1 compares three types of Class A beverage vending machines with 30-ft3 refrigerated volume, and calculates the lifetime cost savings of purchasing efficient models. Federal purchasers can assume products that meet ENERGY STAR efficiency requirements are life cycle cost-effective.

Determine When ENERGY STAR Products Are Cost-Effective

An efficient product is cost-effective when the lifetime energy savings (from avoided energy costs over the life of the product, discounted to present value) exceed the additional up-front cost (if any) compared to a less efficient option. ENERGY STAR considers up-front costs and lifetime energy savings when setting required efficiency levels. Federal purchasers can assume ENERGY STAR-qualified products and products that meet FEMP-designated efficiency requirements are life cycle cost-effective. In high-use applications or when energy rates are above the federal average, purchasers may save more if they specify products that exceed federal efficiency requirements (e.g., the best available model).

Purchasing Requirements

A gavel on top of a stack of papers.

Federal laws and requirements mandate that agencies purchase ENERGY STAR-qualified products or FEMP-designated products in all product categories covered by these programs and in any acquisition actions that are not specifically exempted by law.

These mandatory requirements apply to all forms of procurement, including construction guide and project specifications; renovation, repair, energy service, and operation and maintenance (O&M) contracts; lease agreements; acquisitions made using purchase cards; and solicitations for offers.

FAR Contract Language

Hands on a keyboard.

Federal Acquisition Regulation (FAR) Part 23.206 requires agencies to insert the clause at FAR section 52.223-15 into contracts and solicitations that deliver, acquire, furnish, or specify energy-consuming products for use in federal government facilities. 

To comply with FAR requirements, FEMP recommends that agencies incorporate efficiency requirements into technical specifications, the evaluation criteria of solicitations, and the evaluations of solicitation responses.

Refrigerated Beverage Vending Machine Service Contracts

Vending machines are often part of a contractual arrangement with distributors in which these products are placed in federal facilities at no charge. In return, federal agencies provide space and the electrical power necessary to operate the vending machines. In some cases, the agency may receive a portion of the revenue from the beverage sales. Agencies must request that the refrigerated beverage vending machines provided through these contracts meet current ENERGY STAR efficiency requirements.

Federal Supply Sources and Product Codes

The federal supply sources for energy-efficient products are the General Services Administration (GSA) and the Defense Logistics Agency (DLA). 

The U.S. Department of Agriculture (USDA) and U.S. Environmental Protection Agency (EPA) provide programs that help federal agencies buy products with positive environmental attributes. 

Identification codes for product categories covered by sustainable acquisition requirements are provided by DLA and the United Nations Standard Products and Services Code (UNSPSC).

Refrigerated Beverage Vending Machine Schedules and Product Codes

GSA offers vending machines through the Multiple Award Schedules Food Service Equipment 336999 and Food Service Equipment 333241

DLA's ENAC for vending machines is "KE."

The UNSPSC for vending machines is 48111101.

Buyer Tips: Make Informed Purchases

Refrigerated beverage vending machines come in two classes. Class A machines are fully cooled and typically have glass fronts that display the beverages on sale and are labeled for "Indoor Use Only." Class B refrigerated beverage vending machines typically have solid fronts, can be used indoors or outdoors, and utilize zone cooling where only a small portion of the products stored in the machine are cooled (usually the next few items to be sold). ENERGY STAR also covers combination vending machines where 25% or more of the surface area on the front of the machine is transparent (Combination A) or machines where less than 25% of the front surface area is transparent (Combination B).

Vending machines come in many sizes or capacities, typically stated in the number of cans or bottles. Larger machines use more energy and cost more to operate. Agencies should require vendors to properly size the beverage vending machines placed in their facilities to avoid excessive energy use and its related cost.

Both new and remanufactured machines are eligible for ENERGY STAR recognition. When replacing refrigerated beverage vending machines, agencies should first check with their distributor to see if there are retrofit kits available that can be combined with existing models to meet ENERGY STAR performance requirements.

Many states and electric utilities offer rebates or other incentives for the purchase of ENERGY STAR-qualified products. Use the ENERGY STAR Rebate Finder to see if your local utility offers these incentives. FEMP’s Energy Incentive Program helps federal agencies take advantage of these incentives by providing information about the funding-program opportunities available in each state.

User Tips: Use Products More Efficiently

ENERGY STAR-qualified vending machines are equipped with controls or software that put the lighting and/or refrigeration systems into a low power state at night, on weekends, or for other periods of prolonged inactivity. Agency staff should request that the vendor activate the low power state most advantageous for their facility and periodically check that it is functioning properly (e.g., lights are turned off late at night or on weekends).
