The EPA provides consumers with information about ENERGY STAR Most Efficient recognized products through a filter on the popular ENERGY STAR Product Finders. You can access the ENERGY STAR Product Finders here.
2025 Product Categories and Proposed Recognition Criteria
The EPA completed a review of the data associated with currently recognized models and found in multiple cases updates to the ENERGY STAR Most Efficient criteria are needed to recognize the best of ENERGY STAR. The EPA is proposing changes for ASHPs, clothes washers, dehumidifiers, room air cleaners, and vent fans. Criteria for ceiling fans, clothes dryers, computer monitors, dishwashers, geothermal heat pumps, refrigerators/freezers, room air conditioners, skylights, and windows/sliding glass doors will remain the same as in 2024.
Ceiling Fans: No changes are proposed for ceiling fans for 2025. Currently, ceiling fan products recognized as ENERGY STAR Most Efficient 2024 represent 16% of certified models. Link to full proposal document
Clothes Dryers: No changes are proposed for dryers for ENERGY STAR Most Efficient 2025. Currently, 11% of all dryer base models qualify for ENERGY STAR Most Efficient 2024 recognition. Link to full proposal document
Clothes Washers: The EPA proposes to revise the criteria for large clothes washers for 2025. For models with a capacity larger than 2.5 ft3, the proposed minimum IMEF value is 3.1 and maximum IWF value is 3.0. With these changes, across all clothes washers, 16 base models from 3 brands would currently be eligible for recognition. This represents 5% of all base models. Link to full proposal document
Computer Monitors: No changes are proposed for computer monitors for 2025. With approximately 4% of certified models meeting the ENERGY STAR Most Efficient 2024 criteria, the current criteria for monitors remain a high-performance benchmark for product redesigns. Link to full proposal document
Dehumidifiers: The EPA proposes to revise the criteria for dehumidifiers for 2025. The proposed minimum criteria for portable dehumidifiers is an IEF of 1.85 for products ≤ 25 pints/day, an IEF of 2.20 for products between 25.01-50 pints/day, and an IEF of 3.40 for products ≥ 50.01 pints/day. The proposed minimum criteria for whole-home dehumidifiers are an IEF of 2.35 for products ≤ 8.0 ft3 and an IEF of 3.81 for products > 8.0 ft3. Currently, 12 base models from 7 brands meet the proposed 2025 ENERGY STAR Most Efficient criteria, which represents 3% of all base models. Link to full proposal document
Dishwashers: No changes are proposed for dishwashers for 2025. Currently, 56 base models from 13 brands qualify for ENERGY STAR Most Efficient 2024. This represents 12% of all base models. Link to full proposal document
Ducted and Ductless Air Source Heat Pumps: The EPA proposes to revise the criteria for air source heat pumps for 2025, based on collaboration with the Consortium for Energy Efficiency (CEE) to better align with 25C tax credit eligibility requirements in 2025. The proposed minimum SEER2 criterion is 16.0. The proposed minimum HSPF2 criteria are 8.0, 7.5, and 8.5, for split system HPs, single-package HPs, and cold climate HPs, respectively. The proposed minimum EER2 criterion for all categories is TBD, pending finalization of CEE’s 2025 tax credit tiers. The EPA is also proposing to remove the installation benefits requirement for ducted models. The low ambient and CVP requirements of ENERGY STAR Version 6 cold climate recognition already correspond to the criteria in CEE optional cold climate levels. Link to full proposal document
Geothermal Heat Pumps: No changes are proposed to the criteria for geothermal heat pumps for 2025, meaning that all ENERGY STAR certified GHP will continue to be recognized as ENERGY STAR Most Efficient. They remain a small part of the residential heating and cooling market, providing radically higher efficiencies particularly at the times the grid is most stressed. Therefore, as a class, they fit the concept that this recognition is intended to highlight. Link to full proposal document
Refrigerators-Freezers and Freezers: The EPA proposes to maintain the 2024 criteria for 2025. There are 38 base models from 9 brands of bottom freezer and side-by-side refrigerators, which represents 5% of the bottom freezer and side-by-side base models. The proposal includes a large number of ENERGY STAR top freezers given their notable efficiency relative to other configurations. For compact refrigerators, there are 47 base models from 24 brands that meet the proposed criteria representing 6% of all compact refrigerator base models. There are 8 upright freezer and chest freezer base models from 6 brands that meet the criteria representing 4% of all standard-size freezer base models. For compact freezers, there are 9 base models from 6 brands that meet the proposed criteria representing 4% of all compact freezer base models. Link to full proposal document
Room Air Cleaners: The EPA proposes to revise the criteria for room air cleaners for 2025, with a change in metrics from Smoke CADR to PM2.5 CADR and Smoke CADR/W to IEF to align with the Department of Energy (DOE) minimum standards metrics. The proposed minimum criteria for products between 30 ≤ PM2.5 CADR < 100 are an IEF of 5.40, for 100 ≤ PM2.5 CADR < 150 are an IEF of 6.60, and for products between 150 ≤ PM2.5 CADR are an IEF of 8.60. Currently, 46 base models from 28 brands meet the proposed 2025 ENERGY STAR Most Efficient criteria, which represents 8% of all base models. Link to full proposal document
Room Air Conditioners: No changes are proposed for the room air conditioner product criteria for 2025. Currently, 11 models qualify for ENERGY STAR Most Efficient 2024 recognition. The EPA anticipates this number will increase as manufacturers redesign models for new DOE room air conditioner efficiency standards, effective spring of 2026. Link to full proposal document
Ventilating Fans: No changes are proposed for inline fans. The EPA proposes to revise the criteria for bathroom/utility room fans for 2025. The proposed minimum criteria for efficacy at high speed will now scale with diameter (i.e. ≥ 1.9D + 2.9 where D equals the diameter or depth of the duct in inches). This proposal is intended to more equitably recognize models designed for four-inch ducts. Link to full proposal document
Windows, Sliding Glass Doors, and Skylights: No changes are proposed for the window and sliding glass door criteria or the skylight and tubular daylighting device (TDD) criteria for 2025. Since the ENERGY STAR Version 7 effective date in the Fall of 2023 and recent alignment of 25C Federal tax credits with ENERGY STAR Most Efficient criteria, the market is still adjusting to the changes. Link to full proposal documents here and here.
In addition to meeting these ENERGY STAR Most Efficient 2025 recognition criteria, products must be ENERGY STAR certified by an EPA-recognized certification body.
The EPA will provide additional information regarding the roll out of ENERGY STAR Most Efficient 2025 recognition with the finalization of these criteria.
The EPA will host a webinar to discuss these proposals with stakeholders on July 18, 2024, from 1-3pm EDT. Please register here. This document as well as the criteria documents can be found here. Please share written comments no later than August 12, 2024, with MostEfficient@energystar.gov. Unless the commenter asks otherwise, all comments will be posted to the ENERGY STAR Most Efficient criteria development page. EPA plans to finalize these recognition requirements in the coming months.

ENERGY STAR Most Efficient enjoys robust utility support and is leveraged by 46 energy efficiency program sponsors, serving over 11 million households. These rebate programs feature one or more product categories covered by ENERGY STAR Most Efficient 2024 and reflect a diverse geographic spread.
ENERGY STAR Most Efficient is also leveraged for retailer incentives as part of the ENERGY STAR Retail Products Platform (ESRPP), an innovative, nationally coordinated, market transformation initiative. ESRPP retailers now represent more than 1,750 appliance storefronts in current program sponsors’ service areas. Currently, in 2024, there are 18 efficiency program sponsors participating in ESRPP currently serving 31% of U.S. households.
The EPA provides consumers with information about ENERGY STAR Most Efficient recognized products through a filter on the popular ENERGY STAR Product Finders. You can access the ENERGY STAR Product Finders here.
2025 Product Categories and Proposed Recognition Criteria
The EPA completed a review of the data associated with currently recognized models and found in multiple cases updates to the ENERGY STAR Most Efficient criteria are needed to recognize the best of ENERGY STAR. The EPA is proposing changes for ASHPs, clothes washers, dehumidifiers, room air cleaners, and vent fans. Criteria for ceiling fans, clothes dryers, computer monitors, dishwashers, geothermal heat pumps, refrigerators/freezers, room air conditioners, skylights, and windows/sliding glass doors will remain the same as in 2024.
Geothermal Heat Pumps: No changes are proposed to the criteria for geothermal heat pumps for 2025, meaning that all ENERGY STAR certified GHP will continue to be recognized as ENERGY STAR Most Efficient. They remain a small part of the residential heating and cooling market, providing radically higher efficiencies particularly at the times the grid is most stressed. Therefore, as a class, they fit the concept that this recognition is intended to highlight. Link to full proposal document
In addition to meeting these ENERGY STAR Most Efficient 2025 recognition criteria, products must be ENERGY STAR certified by an EPA-recognized certification body.
The EPA will provide additional information regarding the roll out of ENERGY STAR Most Efficient 2025 recognition with the finalization of these criteria.
The EPA will host a webinar to discuss these proposals with stakeholders on July 18, 2024, from 1-3pm EDT. Please register here. This document as well as the criteria documents can be found here. Please share written comments no later than August 12, 2024, with MostEfficient@energystar.gov. Unless the commenter asks otherwise, all comments will be posted to the ENERGY STAR Most Efficient criteria development page. EPA plans to finalize these recognition requirements in the coming months.

Refrigerators-Freezers and Freezers: The EPA proposes to maintain the 2024 criteria for 2025. There are 38 base models from 9 brands of bottom freezer and side-by-side refrigerators, which represents 5% of the bottom freezer and side-by-side base models. The proposal includes a large number of ENERGY STAR top freezers given their notable efficiency relative to other configurations. For compact refrigerators, there are 47 base models from 24 brands that meet the proposed criteria representing 6% of all compact refrigerator base models. There are 8 upright freezer and chest freezer base models from 6 brands that meet the criteria representing 4% of all standard-size freezer base models. For compact freezers, there are 9 base models from 6 brands that meet the proposed criteria representing 4% of all compact freezer base models. Link to full proposal document

Dear ENERGY STAR® Commercial Electric Cooktop Stakeholder:
The U.S. Environmental Protection Agency (EPA) has updated the ENERGY STAR Commercial Electric Cooktop Version 1.0 (Rev. May 2024) Specification to remove simmer energy-efficiency from the definitions and reporting section of the specification. It was brought to EPA’s attention that the definition included in the specification is not clear and there is no reference to the way the efficiency should be determined through the test method, which is limited to measuring the simmer energy rate. EPA has also removed this field for certification bodies to submit data on certified models.

Dear ENERGY STAR® Computers Partner or Other Interested Stakeholder,
The U.S. Environmental Protection Agency (EPA) invites public comment on the enclosed Draft 2, Version 9.0 ENERGY STAR Computers specification. EPA will hold a stakeholder webinar on May 21, 2024 from 1-3PM ET to discuss the Draft 2 specification in greater detail. Comments on this draft proposal may be submitted to EPA no later than June 4, 2024. Note boxes throughout the specification provide EPA’s rationale for proposals. Also attached to this distribution is an updated data package that includes the EPA dataset, Draft 2 proposed levels, and savings estimates.
In developing the Draft 2 specification, EPA considered the feedback submitted by stakeholders. In total, five stakeholders submitted feedback on the Draft 1 proposal. The Draft 2, Version 9.0 specification incorporates the following key elements:
Energy Criteria: EPA received further data from stakeholders, which allowed many new products to be included in the updated dataset. While the addition of these products did not change the approach outlined in Draft 1, it did support a change in the base allowances. As such, the base allowances have been updated to identify the top quartile of products in the market for desktop computers, notebook computers, and integrated desktop computers. As with Draft 1, no changes have been made to the workstation criteria at this time.
Power Supply Criteria:
After consideration of comments received, EPA is proposing to retain the internal power supply (IPS) requirements from Version 8.0 in the Draft 2 specification. EPA believes that the program will have more impact continuing with more stringent lower load efficiency requirements than increasing the higher load requirements through 80Plus Silver or equivalent efficiencies .
EPA also received comments on allowing manufacturers to test with a recommended adaptor rather than an in-box adaptor for adaptors larger than 35W. EPA remains concerned about impacts on efficiency and performance when potentially pairing a notebook with the incorrect adaptor and has retained the test method references in the Draft 2. In addition, EPA received comments on a temporary solution for workstation testing. However, the Agency has concerns about the approach and has retained the current structure in Draft 2. EPA may consider exempting those products from the reporting requirement in the event the test method cannot be run on workstations.
Stakeholder Webinar
EPA will host a webinar to answer any questions on the Draft 2, Version 9.0 specification on May 21, 2024 from 1-3 PM Eastern Time. Please register here if you plan on attending.
Comment Submittal
The public is encouraged to provide written comments to computers@energystar.gov no later than June 4, 2024. All comments will be posted to the ENERGY STAR Product Development website unless the submitter requests otherwise.
The exchange of ideas and information between EPA, industry, and other interested parties is critical to the success of ENERGY STAR. Specifications and meeting materials will be distributed via email and posted on the ENERGY STAR website.

Dear ENERGY STAR® Central Air Conditioner Manufacturer or Other Interested Party:
On May 18, 2023, the Environmental Protection Agency (EPA) distributed a proposal to sunset the ENERGY STAR specification for central air conditioners (CAC). The ENERGY STAR program serves an important role in helping consumers realize the benefits of energy efficiency from both a cost and environmental perspective. ENERGY STAR specifications are periodically reviewed and updated to ensure that they provide meaningful differentiation for highly energy-efficient products. The EPA develops new and updated specifications through a transparent process in consultation with manufacturers, brand owners, and other stakeholders before making decisions consistent with the program’s objectives and principles. With this letter, the EPA is proposing to delay the sunset of the ENERGY STAR Central Air Conditioner specification to February 1, 2026, with no new certifications accepted after May 1, 2026, allowing additional time for the transition.
The Agency appreciates the extensive stakeholder engagement and comments on the CAC sunset proposal. The majority of commenters responding to the May 2023 proposal supported the CAC sunset, noting that in virtually all parts of the US using a heat pump instead of an air conditioner saves energy, money, and greenhouse gas emissions by partially or fully offsetting other heat sources. In addition, several pointed out that Inflation Reduction Act programs more than account for the cost difference between a heat pump and a CAC. Some objected to the CAC sunset based on their interest in continuing to promote efficient CAC systems in regions where heat is not needed. In addition, a few indicated that the proposed timeline was too fast for the HVAC industry. One commentor that supported the sunset also asked for a slower timeline than originally proposed.
The EPA notes that an extremely limited number of US households operate without some form of heating and to the extent homeowners wish to purchase central air conditioners, they will continue to be able to distinguish energy saving models based on the EnergyGuide label. The delay proposed here would allow more time for the HVAC industry and utility incentive programs in cooling-only climates to prepare for the change.
The public is encouraged to provide written comments on the revised CAC sunset proposal for the EPA’s consideration to HVAC@energystar.gov by May 16, 2024. All comments will be posted to the ENERGY STAR Product Development website unless the submitter requests otherwise.
Please direct any specific questions to Holly Tapani, EPA, at Tapani.Holly@epa.gov or 202-564-0679 and Megan McNelly, ICF, at megan.mcnelly@icf.com or 703-934-3726.

Dear ENERGY STAR® Furnace Stakeholder or Other Interested Party:
On May 18, 2023, the Environmental Protection Agency (EPA) distributed a proposal to sunset the ENERGY STAR specification for furnaces. The Agency appreciates the extensive stakeholder engagement and comments on this proposal 1. In response to compelling support for continuing the labeling of furnaces, the EPA has decided to propose an update, rather than sunset, to the ENERGY STAR furnace specification. The proposal to sunset the ENERGY STAR specification for central air conditioning is addressed in a separate letter.
The ENERGY STAR program serves an important role in helping consumers realize the benefits of energy efficiency from both a cost and environmental perspective. ENERGY STAR specifications are periodically reviewed and updated through a transparent process to ensure that they provide meaningful differentiation for highly energy-efficient products as markets evolve.
The ENERGY STAR furnace specification includes requirements for gas and oil products and was last updated in 2013. With the Department of Energy’s recent finalization of the gas furnace federal minimum efficiency standards at the current ENERGY STAR efficiency level of 95 AFUE and an ENERGY STAR market share of about 40%, the Agency sees an opportunity for further differentiation as the market advances to meet the new minimum requirements effective in December 2028. In addition, increasing the gas furnace efficiency requirement will align the ENERGY STAR specification with eligibility requirements for Section 25C tax credits established under the Inflation Reduction Act. The EPA also proposes to increase efficiency levels for oil furnaces, of which close to 90% of models meet current ENERGY STAR requirements. ENERGY STAR certified oil furnaces would remain eligible for tax credits.
Furnace Specification Revision
With this letter, the EPA is distributing a first draft of the Version 5.0 ENERGY STAR furnace specification and is targeting an effective date of 2026. If all furnaces sold in the United States met the proposed requirements, the cost savings would grow to over $2 billion each year and more than 17 billion pounds of annual greenhouse gas emissions would be prevented.
Key elements of Draft 1 specification revision include:
- An increase in stringency for the gas furnace requirement to 97 AFUE. Nearly 500 furnace models, representing all common sizes and all major manufacturers currently meet this level2.
- A proposal to eliminate the regional distinction for ENERGY STAR furnaces, to align with current minimum efficiency standards and simplify program administration and participation. Sales data reported to the EPA indicates that consumers are generally not taking advantage of the U.S. South performance level.
- An increase in stringency for the oil furnace requirement to 87 AFUE. While more stringent than the eligibility requirements for federal tax credits, this level offers a consumer pay back of less than two years2. At least 13% of oil furnace models will meet the proposed criteria.
Future Plans
In addition to updating the ENERGY STAR furnace specification, the EPA remains interested in the potential for dual-fuel HVAC systems to serve as a lower cost option in cold climates. The Agency is considering a new specification recognizing furnaces in the context of new dual fuel heating systems (i.e. furnace plus heat pump), relying on system metrics developed in collaboration with industry. The EPA plans to work with stakeholders in 2024 to finalize a test procedure, evaluate performance data and develop a proposed specification. Because the furnaces in these systems will run on a limited basis, it may make sense to specify lower furnace efficiency in the interest of overall cost.
Further, the EPA recognizes that the requirement for heat pumps to be rated with specific furnaces is a barrier to ENERGY STAR certification for heat pumps installed in households with an existing furnace. The Agency is investigating how best to address this situation and seeks stakeholder feedback.
Comment Submittal
The public is encouraged to provide written comments on the proposed furnace specification revision for the EPA’s consideration to HVAC@energystar.gov by May 16, 2024. All comments will be posted to the ENERGY STAR Product Development website unless the submitter requests otherwise.
Stakeholder Meeting
The EPA will host a webinar on Wednesday, May 1, 2024, from 3 to 5 pm ET to discuss the Draft 1 furnaces specification revision and address initial stakeholder comments and questions. Please register for the webinar here. Stakeholders are encouraged to inform the EPA of any industry events that may conflict with this proposed date.

Dear ENERGY STAR® Medical Imaging Equipment Stakeholders:
The U.S. Environmental Protection Agency (EPA) invites public comment on the enclosed Draft 2, Version 1.0 ENERGY STAR Medical Imaging Equipment specification. EPA will hold a stakeholder webinar on April 17, 2024, from 12-2PM ET to discuss the Draft 2 specification in greater detail. Comments on this draft proposal may be submitted to EPA no later than May 1, 2024.
The EPA continues to look for ways to provide end-users with improved access to power management. This draft specification adds two elements, operational hours and non-operational hours, which have separate power management criteria. While products may have these functionalities already, the program seeks to automate power management in the case of operational hours and improve the visibility and ultimately make it easier for end-users to work with their vendors to engage power management during non-operational hours.
Overview of Draft 2 Proposal
The EPA received comments from a variety of end-users supporting the effort to create an ENERGY STAR program for medical imaging equipment along with more specific comments on the criteria. Based on these comments, EPA has updated the definitions, scope, test methodology, and criteria elements in Draft 2 after extensive conversations with the public. Note boxes throughout the specification explain the rationale for the changes to the specification.
Key elements of the Draft 2 proposal include:
Scope:
After further discussion with stakeholders, the EPA has determined that it will focus on Magnetic Resonance Imaging (MRI) devices in the Version 1.0 specification and is developing a roadmap with industry stakeholders to collect data to incorporate the other modalities as part of a future revision.
Power Modes and Auto-Power Down:
As part of the amendments made to the Draft 2, the EPA has added definitions for operating hours and non-operating hours and has created power down criteria for each. For operating hours, MRI devices will go into a power saving mode that saves at least 7% (depending on MRI type) compared to the Ready to Scan mode. This power saving mode would be automatic. During non-operating hours, the product would need to be able to reduce its power consumption in a power saving mode by at least 16% (depending on the MRI type). This, however, will not be automatic at this time. There is a desire that moving the MRI into a lower power state should be a conscious decision by the user based on the situation at the time of closing. The EPA is planning on developing materials with stakeholders to provide further information on how to best do this.
The EPA also has retained an interest in providing end-users with the best possible information on the energy consumption of the product. However, stakeholders noted that the numbers obtained through testing may not be a particularly accurate representation of the energy profile of the specific product obtained by the end-user. The EPA is considering additional ways to provide accurate information that allows hospitals and other medical facilities to estimate their consumption and will provide an update in the next draft of the specification.
Test Method:
The Department of Energy (DOE) has made two slight modifications to the test method, adding one test to allow for testing the power saving condition when the product is in the operating hours and noting that the ENERGY STAR test method currently only applies to MRI devices.
Stakeholder Meeting:
The EPA will host a webinar on April 17, 2024, from 12-2PM Eastern Time to answer any questions on this discussion guide. Please register to attend the webinar here.
Comment Submittal:
The public is encouraged to provide written comments to medicalimaging@energystar.gov no later than May 1, 2024. All comments will be posted to the ENERGY STAR Product Development website unless the submitter requests otherwise.
The exchange of ideas and information between EPA, industry, and other interested parties is critical to the success of ENERGY STAR. Specifications and meeting materials will be distributed via email and posted on the ENERGY STAR website. To track EPA’s progress on this specification, please visit the product development website.

Dear ENERGY STAR® Room Air Conditioners Brand Owner Partners and Other Interested Stakeholders:
The U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) are announcing the release of the Final Draft ENERGY STAR Test Method to Determine Room Air Conditioner Heating Mode Performance and invite the public to submit comments to appliances@energystar.gov no later than April 15, 2024.
In response to the Draft 1 Test Procedure, the EPA received generally supportive comments from stakeholders with a few recommended changes. The EPA and the DOE have adjusted the Final Draft Test Procedure in response to the comments received; responses to comments can be found in note boxes throughout the Final Draft Test Procedure as well as in the accompanying Draft 1 Comment Response Matrix. As a reminder, the development of this test procedure is being led by the DOE in advance of EPA adding a heating mode test requirement to the ENERGY STAR Room Air Conditioners specification at some point in the future. In the meantime, brand owner partners will be able to update their certification to include heating mode test results for ENERGY STAR reverse cycle models once the test procedure is final. The EPA plans to include the heating mode efficiency in the ENERGY STAR dataset.
Key elements of the Final Draft Test Procedure include:
- Definition of room heat pump types
- Altered from mild, cool, cold climate, and other to Types 1-4
- Removed the capacity ratios and efficiency requirements
- Clarification that supplemental test instructions may vary fan speed according to the test condition
- Addition of a simulated cut-out
- Added test conditions for both single-speed and variable-speed units with active defrost but have cut-in and cut-out temperatures above 17 °F
- H2,int test is now optional for all units to reduce overall test burden
- Meltwater required to be drained using an indoor or outdoor drain port, if possible, during tests
- Small non-substantive corrections and formatting adjustments to the equations
Comment Submittal:
The public is encouraged to provide written comments to the EPA and the DOE by Monday, April 15, 2024, to appliances@energystar.gov. As always, stakeholder engagement is a critical to the success of the ENERGY STAR program and the EPA and the DOE look forward to working with all parties to develop the ENERGY STAR Heating Mode Test Procedure for Room Air Conditioners.

Final Draft ENERGY STAR Test Method to Determine Room Air Conditioner Heating Mode Performance
ENERGY STAR Draft 1 Test Method to Determine Room Air Conditioner Heating Mode Performance Comment Response Matrix
The U.S. Environmental Protection Agency (EPA) invites the public to submit comments on the enclosed Draft 1 ENERGY STAR Version 6.0 Dehumidifiers specification. EPA will hold a stakeholder webinar on March 28, 2024, at 1p.m. ET to discuss the Draft 1 specification in greater detail. Comments on this draft proposal may be submitted to EPA no later than April 12, 2024.
Since the current Version 5.0 specification took effect in February 2019, the dehumidifier market has evolved quite a bit, with the market share of ENERGY STAR certified models rising significantly in the past few years to 90%. This presents an opportunity for the ENERGY STAR program to deliver additional energy savings and improve the consumer value the label provides.
Overview of Draft 1 Proposal
The basis for this Draft 1 proposal is to increase stringency to provide better market differentiation for ENERGY STAR dehumidifiers and capture even greater energy, greenhouse gas, and cost savings. EPA is proposing that to qualify for ENERGY STAR, dehumidifiers must be at least 18-58%, depending on product class, more efficient than the current minimum standard. Approximately 19% of current base models meet the proposed levels. Based on a comparison of similar models with different efficiency performance, EPA found that energy cost savings paid back the incremental cost in less than one year for most product classes. EPA estimates that at the proposed levels of efficiency, annual cost savings will grow to over $350 million and approximately 7 billion pounds of greenhouse gas emissions will be prevented each year. As with all ENERGY STAR products, EPA is working with DOE on this ENERGY STAR revision and will ensure the revision is informed by the DOE regulatory process.
Key elements of the Draft 1 proposal include:
- Integrated Energy Factor (IEF) criteria for portable dehumidifiers ≤ 25.00 pints/day, 25.01 to 50.00 pints/day, and ≥ 50.01 pints/day as well as for whole-home dehumidifiers with case volumes ≤ 8.0 cubic feet and > 8.0 cubic feet (as tested according to 10 CFR 430, Subpart B, Appendix X1).
- A minor update to the IEF definition to be in alignment with the DOE definition.

Dear ENERGY STAR® TV Partner or Other Interested Stakeholder:
With this letter, the U.S. Environmental Protection Agency (EPA) is sharing the ENERGY STAR Televisions Version 9.1 Final Specification. This final specification references the U.S. Department of Energy’s Uniform Test Method for Measuring the Energy Consumption of Television Sets incorporated in Appendix H to Subpart B of 10 CFR Part 430, published in a Final Rule on March 15, 2023 and effective April 14, 2023. Updates to Appendix H align with the finalized, industry-developed test method, ANSI/CTA-2037-D: Determination of Television Set Power Consumption.
The Televisions Final Version 9.1 Specification has not changed since Version 9.1 Draft Specification’s publication on August 3, 2023, as no comments were received. The Version 9.1 Specification accounts for updates to Appendix H. These updates include:
- Updated, added, and removed definitions;
- removed requirements for previously defined modes;
- revised the power measurement interpolation instructions for models that would otherwise be certified at a dynamic luminance level below given thresholds; and
- updated the applicable test procedures to reference Appendix H to Subpart B of 10 CFR Part 430.
Products already certified to Version 9.0 will not need to be retested to maintain their ENERGY STAR certification; however, all new certifications will be based on testing per Appendix H to Subpart B of 10 CFR Part 430 (i.e., ANSI/CTA-2037-D). To ensure consistent reporting of efficiency metrics, EPA encourages manufacturers with products already certified to the Version 9.0 specification to work with their certification bodies to update their reported performance metrics consistent with testing from the updated Appendix H to Subpart B of 10 CFR Part 430.

ENERGY STAR Televisions Version 9.1 Final Specification
Dear ENERGY STAR ® Laboratory Grade Refrigerator and Freezer Partner or Other Interested Stakeholder:
This letter is being redistributed due to a sending error impacting some potential recipients this week.
The U.S. Environmental Protection Agency (EPA) is releasing the Draft 2, Version 2 ENERGY STAR Laboratory Grade Refrigerators and Freezers specification. The deadline to submit comments on this draft specification is March 19, 2024.
In response to the Draft 1, Version 2.0 proposal, EPA received numerous comments regarding the criteria. The Agency has taken that feedback into account in developing the Draft 2 proposal and has referred to the comments received and responded to them through the Draft 2 specification. In particular, the Agency assessed the need to further segment the High Performance Refrigerator and Freezer markets based on door type and defrost type. In addition, the ultra-low temperature freezer category was split into two bins to reflect differences in energy consumption of those products. EPA is also proposing energy allowances for High Performance products that certify to NSF 456. In reaching the criteria levels proposed in Draft 2, EPA reviewed all available data sources where products were tested to the ENERGY STAR test method to allow for an appropriate comparison of products. The updated data set that reflects new data has been released with this draft. EPA continued to look to differentiate the market and based on the feedback received from Draft 1 believes that this proposal differentiates the top performers in the market while maintaining a good selection of eligible products for purchasers. Finally, EPA notes that there was interest in expanding the scope of this specification to include combination refrigerator/freezers and cryogenic freezers. However, as of this time, the Agency has no data with which to determine criteria and therefore has continued to exclude these products from scope.
Comment Submittal
Comments on the Version 2.0 Draft Specification may be submitted to labgraderefrigeration@energystar.gov by March 19, 2024. All comments will be posted to the ENERGY STAR Product Development website unless the submitter requests otherwise. Stakeholder comments, previous draft specifications, and related materials are available on the ENERGY STAR Laboratory Grade Refrigerators and Freezers Specification Development webpage.

Dear ENERGY STAR® Boiler Partner or Other Interested Party:
The U.S. Environmental Protection Agency (EPA) has revised the ENERGY STAR Boilers Version 3.0 Specification to update the test method reference to 10 CFR Part 430 Subpart B, Appendix EE in coordination with changes to the code of federal regulations (CFR). The test method referenced in the specification prior to this update was 10 CFR Part 430 Subpart B, Appendix N. However, on March 13, 2023, the Department of Energy (DOE) issued a final rule pertaining to the test procedure for boilers, which resulted in moving provisions for consumer boilers to this new appendix EE. In appendix EE, DOE includes all provisions previously included in appendix N relevant to consumer boilers, with no substantive modifications.
Thank you for your support of ENERGY STAR.
Dear ENERGY STAR® Brand Owner or Other Interested Party:
The U.S. Environmental Protection Agency (EPA) has selected two new categories for recognition with the 2024 ENERGY STAR Emerging Technology Award: Commercial HVAC Electric Motors and Modular Packaged Commercial Refrigeration Systems. EPA is proposing recognition and draft performance criteria for these product categories with the goal of recognizing promising new technologies that offer purchasers new ways to save energy and protect the environment. Interested stakeholders are encouraged to provide comments on the selection of these categories and draft performance levels by February 7, 2024. Following review of those comments, EPA will either release new draft product performance criteria or develop and release final criteria.
Overview of the Emerging Technology Award
Launched in 2011, the ENERGY STAR Emerging Technology Award raises the profile of innovative technologies that have the potential to significantly reduce greenhouse gas emissions once more widely adopted. The annual Award recognizes promising technologies that may not yet meet key principles associated with product categories eligible for the ENERGY STAR label (e.g., those that are broadly available, cost effective to the consumer) or may represent large improvements in existing ENERGY STAR product categories. As products become more mainstream, Award categories may become candidates for ENERGY STAR specification development. For more information on the Award, visit www.energystar.gov/emergingtech.
2024 Award Extension Notice for Commercial or Industrial Heat Pump Dryers
With this letter EPA is extending the existing award category for Commercial or Industrial Heat Pump Dryers into 2024. Commercial or Industrial Heat Pump Dryers remain a promising technology as they have the potential to deliver dramatic energy improvements to commonly used commercial and industrial product categories. Extending this award category into 2024 provides EPA and manufacturers additional time to develop final test method and performance criteria.
2024 New Category Proposal: Commercial HVAC Electric Motors
Electric motors are the largest electrical end use category in the world, currently consuming 45% of all electricity at a cost projected to reach $900 billion per year by 2030. 1 This presents a large opportunity for efficiency, provided the right market factors and motor technologies. Following the call for product category nominations EPA received a proposal to recognize electric motors that comply with the most rigorous efficiency performance levels from the International Electrotechnical Commission (IEC): the “IE-5” level (levels range from IE1 – IE5). Recognized in Europe but also in the USA by the National Electrical Manufacturers Association (NEMA) and the Consortium for Energy Efficiency, motors rated to the “IE” scale have been receiving utility program support, but only up to the “IE – 4” level. In this letter EPA is supporting the establishment of the Emerging Technology Award for commercial HVAC motors that achieve performance at IE-5 level. There are several advantages to this approach:
- There is a well-established international test method in place.
- Existing manufacturers already make products.
- Utility programs may elect to modify their programs by raising performance levels to recognize products that meet the Award levels.
- Motors represent the largest electrical end use in the world, representing 45% of total consumption and even a small increase in efficiency can have a large impact.
- Motors are inexpensive relative to the total cost of ownership, with purchase price to the total cost of ownership, with purchase price representing just 1% of the total cost, which is mostly electrical optional cost.
In addition to energy savings from increased efficiency, there are other technology improvements associated with IE-5 motors which offer advantages to users that could help speed adoption of this technology.
- Quieter operation
- Lower temperature operation
- Longer life
- Reduced energy losses of 20% (vs IE-4) motors, and 40% (vs IE-3) motors
- No use of rare earth materials in magnets
- Efficiency savings ranging from 5% (motor only) and 25% (when variable fan and drive systems are included.)
2024 New Category Proposal: Modular Packaged Commercial Refrigeration Systems
The type of commercial refrigeration equipment found in grocery stores that permits customers to reach into freezers, or vertical doored systems holding frozen or chilled foods and beverages, are known in the industry as “self-serve.” Typically, these systems are cooled by large rooftop units which have long tubes of refrigerants providing cooling to the rows of self-serve refrigerators (as found in grocery store isles). There are three problems associated with this existing product design: 1) during service the entire row of refrigerators or freezers goes off-line, leading to spoiled foods; 2) legacy systems use refrigerants that have high global warming potential; and 3) legacy systems are prone to refrigerant leaks due to the long length of the refrigerant tubing.
During the call for nominations, EPA received a proposal to recognize a new product category in commercial refrigeration most simply called the “modular packaged system.” The characteristics of this system are that the refrigeration systems are self-contained; there is one packaged cooling system per refrigerator/freezer (eliminating the rooftop unit); they use low GWP refrigerants, and they work as “drop in” replacements for legacy technologies. Given the large technical potential that exists with the legacy systems that will need to be replaced due to mandatory refrigerant phase outs, EPA agrees that this product category has the potential to play an important role in this market. Establishing an Emerging Technology Award category could help accelerate the market by establishing performance criteria and giving buyers more confidence in the new systems.
Interested stakeholders are encouraged to provide feedback on the attached proposed recognition criteria to emergingtech@energystar.gov by February 7, 2024. Depending on the comments received, EPA may release subsequent drafts for stakeholder review prior to finalizing the criteria.
If you have any questions about the Award or the criteria development process, please contact me, Peter Banwell, at banwell.peter@epa.gov or (202) 343-9408 or emergingtech@energystar.gov.
