The Federal Energy Management Program (FEMP) provides acquisition guidance for geothermal heat pumps, a product category covered by ENERGY STAR. 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 for geothermal heat pumps applies to open loop, closed loop, and direct geoexchange products that operate on single-phase current.
Commercial products, those that operate on three-phase electric current, are excluded.
This acquisition guidance was updated in December 2015.
Find Product Efficiency Requirements
The U.S. Environmental Protection Agency (EPA) provides geothermal heat pump program requirements and efficiency criteria on the ENERGY STAR website. Manufacturers meeting these requirements are allowed to display the ENERGY STAR label on complying models. Federal buyers can use ENERGY STAR's list of certified geothermal heat pumps to identify or verify complying models.
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.
