MFNC Program Requirements and Checklists, Version 1:

These documents have been revised based on stakeholder feedback received in the summer of 2018. The updated versions, along with two new program documents, were posted October 31, 2018.

MFNC Caribbean Program Requirements, Version 1:

EPA received feedback about challenges and applicability of implementing the Multifamily New Construction National Program, in Puerto Rico and the US Virgin Islands as well as the potential challenges with the Certified Homes Caribbean Program Requirements, Version 1 for multifamily high-rise projects. Acting on that feedback, EPA drafted a modified set of program requirements based on the Certified Homes Caribbean Program Requirements, named the MFNC Caribbean Program Requirements, Version 1.

EPA held the Draft MFNC Caribbean Program Requirements webinar (PDF, 1.7 MB) on Wednesday, August 19, 2020 to provide the rationale for developing the MFNC Caribbean Program Requirements, provide an overview of the draft requirements, explain how stakeholders can provide comments, and answer initial questions. Contact energystarhomes@energystar.gov to receive a recording of this event.

EPA conducted a comment period from August 13 through September 10, 2020 on these draft program requirements. EPA requested feedback on the below documents.

These documents have been revised based on stakeholder feedback received in the Fall of 2020. The updated versions were posted January 18, 2021.

Multifamily Workbook:

Note: This resource was formerly referred to as the Testing and Verification Worksheets.

Conceptual Draft Multifamily Workbook (EXCEL, 143 KB):
EPA received multiple comments that using PDF checklists were challenging for multifamily projects and a better method was needed to verify the Rater Design Review and Field checklist items across multiple dwelling units and common spaces. The conceptual draft Multifamily Workbook provides an Excel version of the Rater Design Review and Rater Field checklists and additionally includes tracking information on testing and inspections. It also captures the energy efficiency measures.

This Excel spreadsheet will be used by MROs to review multifamily projects using the ASHRAE or Prescriptive Paths under the new specification. As specified in the MRO application amendment, MROs can create their own version of this spreadsheet or choose to accept the PDF checklists and other testing spreadsheets. For multifamily projects using the ERI Path this spreadsheet is an optional document and is not required.

Note: This is a very early conceptual draft and the functionality is not all included. Some worksheets contain notes on what functionality will be implemented. Some checklist items may be missing and the text may not be the most recent version. The final version is expected to be available in early 2019.

Release of ENERGY STAR National SFNH v3.2 / MFNC v1.2 and NextGen Program Requirements

May 16, 2022

Since October 2021, EPA has engaged stakeholders on several important initiatives to advance the ENERGY STAR Residential New Construction program requirements. 

1. EPA has finalized new program requirements, called Single-Family New Homes (SFNH) National v3.2 and Multifamily New Construction (MFNC) National v1.2, for states that adopt the 2021 IECC or equivalent. 

Consistent with the Draft 2 proposal, the new requirements will maintain savings of at least 10% while advancing the thermal backstop to 100% of the 2021 IECC UA value in January 2025. An interim backstop of 105% of the 2021 IECC UA value will be provided for homes and apartments permitted prior to this date. 

The final ENERGY STAR ERI Target Procedures have been posted on the ENERGY STAR program requirements web page so that EPA can begin working with rating software providers to support these new versions. The remaining final documents, consistent with the Draft 2 proposal, will be released with the next Revision of the program, anticipated this Fall. 

2. EPA has finalized the technical specifications for a new certification label that provides additional recognition for new homes & apartments that include efficient electric technologies and EV charging capability.  

EPA is beginning work on developing program infrastructure, guidance materials/resources, training, and marketing materials to support a launch of the new program, called ENERGY STAR NextGen Homes and Apartments, in 2023. The technical specifications are now posted for reference purposes; however, homes and apartments may not be certified until the program is launched next year.

Release of ENERGY STAR California SFNH v3.3 / MFNC v1.3 and Extension of HCO Oversight to California

May 16, 2022

In response to California's more stringent 2019 Building Energy Efficiency Standards, EPA proposed new versions of the ENERGY STAR Single-Family New Homes (SFNH) and Multifamily New Construction (MFNC) Program Requirements for California. In addition, EPA proposed to extend the Home Certification Organization (HCO) construct to cover homes and apartments certified in California. 

1. EPA has finalized the new program requirements for California, called SFNH California Version 3.3 and MFNC California Version 1.3, with an implementation date of January 1, 2023.  

Consistent with the Draft 1 proposal, the new program updates will maintain savings of at least 10% relative to California's more stringent 2019 Building Energy Efficiency Standards. The final requirements have been posted on the ENERGY STAR program requirements web page. 

2. EPA has finalized the extension of the Home Certification Organization oversight structure to California, beginning with homes and apartments certified using SFNH California Version 3.3 and MFNC California Version 1.3. 

Consistent with the Draft 1 proposal, EPA will require that raters work under the auspices of an HCO that has been recognized by EPA to operate in California when certifying homes and apartments to SFNH California Version 3.3 and MFNC California Version 1.3 (and later) using a dwelling unit modeling approach. EPA is actively working with oversight organizations in the state and nationally to ensure they are informed about the extension of the HCO requirement to California. Learn more about Home Certification Organizations.

Draft ENERGY STAR Residential New Construction Program Requirements for California, Single-Family New Homes Version 3.3 / Multifamily New Construction Version 1.3 and Extension of Home Certification Organization (HCO) Oversight to California

April 18, 2022 - May 2, 2022 (NOW CLOSED)

In response to California's more stringent 2019 Building Energy Efficiency Standards, EPA proposed new versions of the ENERGY STAR Single-Family New Homes (SFNH) and Multifamily New Construction (MFNC) Program Requirements for California. These new versions are intended to ensure that ENERGY STAR certified homes and apartments will continue to offer meaningful savings relative to those that are not certified.

In addition, EPA proposed to extend the Home Certification Organization (HCO) construct to cover homes and apartments certified in California using a dwelling unit modeling approach. The requirement to certify through an HCO would be in effect for homes and apartments certified using the new California Program Requirements versions referenced above (SFNH v3.3 and MFNC v1.3). Organizations would be able to apply for HCO recognition at the national level, in California only, or both nationally and in California.

Draft California SFNH v3.3 / MFNC v1.3 and Extension of HCO Oversight to California documents for stakeholder feedback, all comments received from partners and other stakeholders, and EPA's Response to Stakeholder Feedback are available.

EPA presented on these initiatives on April 18, 2022. Review the slides below and contact energystarhomes@energystar.gov to receive a recording of these sessions.

ENERGY STAR Residential New Construction Program Roadmap and Framework Document - Second Stakeholder Feedback Period

March 21, 2022 - April 15, 2022 (NOW CLOSED)

In October 2021, EPA released an ENERGY STAR Residential New Construction Program Roadmap/Framework Document, which contained proposals for three important initiatives to advance and expand the ENERGY STAR Residential New Construction programs. 

EPA received a significant amount of stakeholder feedback on its proposal to introduce new versions of both the Single-Family New Homes and Multifamily New Construction program requirements, called SFNH National Version 3.2 and MFNC National Version 1.2, respectively, which will be implemented in states that adopt the 2021 IECC or an equivalently stringent code.

While commenters provided feedback on a variety of issues related to the proposed new program requirements, the majority of comments received were related to the new proposed Thermal Backstop. EPA appreciates the variety of input received on this issue. All comments received from partners and other stakeholders and EPA's Response to Stakeholder Feedback are now available.

In response to stakeholders' feedback, EPA developed revised Draft 2 Single Family Version 3.2 and Multifamily Version 1.2 program requirements.

The primary change contained in Draft 2 was that EPA revised the proposed thermal backstop in Draft 2 of the SFNH v3.2 and MFNC v1.2 program requirements. While the original proposal to align the thermal backstop with the 2021 IECC was retained, a transition period was added to allow homes and apartments permitted before January 1, 2025, to be certified with a total building thermal envelope UA that is less than or equal to 105% of the total UA resulting from the U-factors in the 2021 IECC. 

The thermal backstop defines the minimum levels of insulation and window performance that a home or apartment must use and is designed to ensure that insulation and windows are not traded off for other efficiency measures to a degree that EPA believes would negatively impact performance and homebuyer comfort. EPA recognizes that some stakeholders have advocated for keeping the backstop at the 2021 IECC prescriptive levels, or an equivalent UA value, as originally proposed, while others support a less stringent backstop that would allow for more flexibility in tradeoffs of the envelope with other measures. 

EPA notes that there is precedent for EPA setting the thermal backstop in alignment with the Reference Design, as it did when SFNH v3.0 and MFNC v1.0 were first introduced, as well as for setting the backstop at a lower level than the Reference Design, as it did for SFNH v3.1 and MFNC v1.1. In this case, EPA believes it is important to set a high bar for the insulation and window levels to ensure the long-term performance of certified homes and apartments as the program advances. 

At the same time, EPA recognizes that increasing the thermal backstop from the 2009 IECC (as used in the prior versions) to the 2021 IECC is a significant advancement, and based on the feedback received, EPA believes that providing partners with additional time to prepare for such a change is warranted, particularly in the first states to have the new versions enforced.  

As a result, EPA revised the proposed thermal backstop in Draft 2 as described above. This represents a significant immediate and long-term advance in the thermal backstop while providing partners and the market with a reasonable amount of time to develop solutions that achieve the full 2021 IECC enclosure levels. 

​EPA has provided a redline track changes version of the revised proposal to allow stakeholders to easily identify all of the updates that have been made in the revised draft.

Updates on Additional Initiatives Proposed by EPA in the ENERGY STAR New Construction Program Roadmap and Framework Document.

1. Transition all states where ENERGY STAR Single-Family New Homes (SFNH) Version 3.0 is still in effect to Version 3.1. Similarly, this transition will move states currently subject to Multifamily New Construction (MFNC) Version 1.0 to Version 1.1 and advance the baseline ASHRAE code in multifamily to ASHRAE 90.1-2010.

  • In December 2021, EPA announced the timeline for the national transition to Single-Family v3.1/Multifamily v1.1. Additional details provided in February 2022 reminder.
  • Single-Family: In states where Version 3.0 of the ENERGY STAR Single-Family New Homes National Program Requirements is still in effect, homes permitted on or after January 1, 2023 will be required to meet Version 3.1.
  • Multifamily: In states* where Version 1.0 of the ENERGY STAR Multifamily New Construction National Program Requirements is still in effect, buildings permitted on or after January 1, 2024 using the Prescriptive or ERI Paths will be required to meet Version 1.1; and those using the ASHRAE Path will be required to meet a performance target baseline of ASHRAE 90.1-2010 or later. (*Due to recent code updates, multifamily buildings in Virginia permitted on or after April 1, 2023, will be required to use Version 1.1 of the National ENERGY STAR Multifamily New Construction (MFNC) program requirements.)

3. Introduce a new advanced certification program, beyond the core ENERGY STAR program requirements, to provide additional recognition for the next generation of homes and apartments that incorporate efficient electric technologies such as heat pumps, heat pump water heaters, induction cooking, and electric vehicle charging capabilities.

ENERGY STAR Residential New Construction Program Roadmap and Framework Document - First Stakeholder Feedback Period

October 18, 2021 - November 15, 2021 (NOW CLOSED)

The Framework Document consists of three important proposed initiatives to advance and expand the ENERGY STAR Residential New Construction programs to keep pace with advancing building codes, foster a clean energy economy, and further reduce greenhouse gas emissions associated with the residential sector. Through the document, EPA is proposing to:

1. Transition all states where ENERGY STAR Single-Family New Homes (SFNH) Version 3.0 is still in effect to Version 3.1. Similarly, this transition will move states currently subject to Multifamily New Construction (MFNC) Version 1.0 to Version 1.1 and advance the baseline ASHRAE code in multifamily to ASHRAE 90.1-2010.

2. Introduce new versions of both the Single-Family New Homes and Multifamily New Construction program requirements, called SFNH National Version 3.2 and MFNC National Version 1.2, respectively. These new versions will maintain the same program structure as Version 3.1 and Version 1.1 and are designed to achieve 10 percent savings relative to the 2021 IECC. The new requirements will only become mandatory in states that adopt the 2021 IECC or an equivalently stringent code.

3. Introduce a new advanced certification program, beyond the core ENERGY STAR program requirements, to provide additional recognition for the next generation of homes and apartments that incorporate efficient electric technologies such as heat pumps, heat pump water heaters, induction cooking, and electric vehicle charging capabilities.

EPA presented on these initiatives. Review the slides below and contact energystarhomes@energystar.gov to receive a recording of these sessions.
