Determination Regarding Energy Efficiency Improvements in the
2024 International Energy Conservation Code
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notification of determination.
-----------------------------------------------------------------------
SUMMARY: The U.S. Department of Energy (DOE) has reviewed the 2024
International Energy Conservation Code (IECC) and determined the
updated edition would improve energy efficiency in residential
buildings. DOE analysis indicates that buildings meeting the 2024 IECC,
as compared with buildings meeting the 2021 IECC, would result in
national site energy savings of 7.80 percent, source energy savings of
6.80 percent, and energy cost savings of approximately 6.60 percent of
residential building energy consumption. Under the Energy Conservation
and Production Act, as amended (ECPA), upon publication of an
affirmative determination, each State must review the energy efficiency
provisions of its residential building code and determine whether it is
appropriate for such state to revise its building code to meet or
exceed the 2024 IECC. Additionally, this notification provides guidance
on state code review processes and associated certifications.
DATES: Certification statements provided by States shall be submitted
by December 30, 2026.
ADDRESSES: A copy of the supporting analysis and a link to the Federal
docket are available at https://www.energycodes.gov/determinations.
Certification Statements must be addressed to the Building
Technologies Office--Building Energy Codes Program Manager, U.S.
Department of Energy, Office of Energy Efficiency and Renewable Energy,
1000 Independence Avenue SW, EE-5B, Washington, DC 20585.

SUPPLEMENTARY INFORMATION:
I. Background
II. Determination Statement
III. State Certification
I. Background
Title III of the Energy Conservation and Production Act, as amended
(ECPA), establishes requirements for DOE to review consensus-based
building energy conservation standards. 42 U.S.C. 6831 et seq. Section
304(a) of ECPA, as amended, provides that whenever the 1992 Council of
American Building Officials (CABO) Model Energy Code, or any successor
to that code, is revised, the Secretary of Energy (Secretary) must make
a determination, no later than 12 months after such revision, whether
the revised code would improve energy efficiency in residential
buildings, and must publish notice of such determination in the Federal
Register. 42 U.S.C. 6833(a)(5)(A). If the Secretary makes an
affirmative determination, within two years of the publication of the
determination, each State is required to certify that it has reviewed
the provisions of its residential building code regarding energy
efficiency and made a determination as to whether it is appropriate to
revise its code to meet or exceed the provisions of the successor code.
42 U.S.C. 6833(a)(5)(B).
The International Energy Conservation Code (IECC) is the
contemporary successor to the CABO Model Energy Code specified in ECPA.
The IECC is revised every three years through an established code
development and consensus process administered by the International
Code Council (ICC). The ICC published the most recent edition of the
IECC in August 2024 (the 2024 IECC) and triggered the statutorily
required DOE review process. As part of the ICC process, any interested
party may submit proposals, as well as written comments or suggested
changes to any proposal, and make arguments before a committee of
experts assembled by the ICC. The collection of accepted proposals
forms the revised edition of the IECC. More information on the ICC code
development process is available at https://www.iccsafe.org/products-and-services/i-codes/code-development/cs/iecc-residential-consensus-committee.
As required by ECPA, DOE conducts a technical analysis to assess
the energy savings impacts associated with the updated code, the 2024
IECC. DOE's review under ECPA is technical in nature and helps to
inform and advise interested industry stakeholders of the effects of
the updated code, and informs states and local governments who
ultimately adopt, implement, and enforce building codes. Although DOE
is an active participant in the review and update process for the 2024
IECC, as directed under ECPA (42 U.S.C. 6836(b)), the Department
neither administers nor publishes the model energy codes. Additionally,
the directive for states to update their energy efficiency codes based
on the updated edition of the 2024 IECC is required by ECPA. DOE's
technical analysis serves as the basis for DOE's determination and
helps inform states who seek to update their codes and comply with
ECPA.
DOE's full technical analysis, including assumptions and parameters
applied in the analysis, is published as a separate technical support
document (TSD) and available for review at https://www.energycodes.gov/determinations.
DOE publishes a wide range of technical assistance resources
supporting building energy codes. These include additional technical
analyses evaluating the impacts of updated building energy codes, such
as quantifying the energy and environmental benefits, as well as
additional resources supporting the adoption and successful
implementation of energy codes across states and local governments. New
Federal assistance is also available to support state and local
adoption and implementation of building energy codes through the
Bipartisan Infrastructure Law (Section 40511) and Inflation Reduction
Act (Section 50131). Visit www.energycodes.gov to learn more about
these initiatives and technical assistance resources.
II. Determination Statement
Residential buildings meeting the 2024 IECC are expected to
experience the following savings on a weighted national average basis
(compared to the previous 2021 edition):
7.80 percent site energy savings
6.80 percent source energy savings
6.60 percent energy cost savings
6.51 percent carbon emissions savings
[[Page 106459]]
DOE concludes that the 2024 IECC will improve energy efficiency in
residential buildings and, therefore, receives an affirmative
determination under Section 304(a) of ECPA.
III. State Certification
Upon publication of this affirmative DOE determination, ECPA
requires each State to certify that it has reviewed the provisions of
its residential building code regarding energy efficiency and made a
determination as to whether it is appropriate for such State to revise
its residential building code to meet or exceed the 2024 IECC. 42
U.S.C. 6833(a)(5)(B). Each State must complete its certification not
later than 2 years from the date this Notice of Determination is
published in the Federal Register, unless an extension is provided.
In the 2024 IECC development cycle, the IECC-Residential technical
development committee approved several proposals that were later
appealed to the ICC Board of Directors. Per the Board's decision,
several measures that increased building energy performance and
reliance on nondepletable sources of energy were removed from the code
prior to publication and were relegated to optional appendices within
the 2024 IECC. These measures will provide substantial benefits for
consumers, such as supporting grid integration and reliability, and
enabling homes to more readily incorporate high-performance equipment
and appliances, electric vehicle charging and renewable energy systems,
as well as increase resilience against climate hazards. Consequently,
DOE strongly encourages states and local governments to consider
adopting these appendices and measures when updating and certifying
their building energy codes in accordance with the 2024 IECC. The DOE
technical assistance and funding opportunities described below are
available to states and local governments for assessing and adopting
these measures.
State Review & Update
The State certification must be: (1) made after public notice and
hearing; (2) in writing; (3) based upon findings and the evidence
presented at the hearing; and (4) made available to the public. 42
U.S.C. 6833(a)(2). States have discretion regarding the hearing
procedures they use, as long as they provide an adequate opportunity
for members of the public to be heard and present relevant information.
The Department recommends publication of any notice of public hearing
through appropriate and prominent media outlets, such as in a newspaper
of general circulation or electronic formats commonly relied upon for
public announcements. States should also be aware that this DOE
determination does not apply to IECC chapters specific to
nonresidential buildings, as defined in the IECC. Therefore, States
must certify their evaluations of their State building codes for
residential buildings with respect to all provisions of the IECC,
except for those chapters not affecting residential buildings. DOE
determinations regarding earlier editions of the IECC are available on
the DOE Building Energy Codes Program website.\1\ Further technical
analysis is also available to help quantify the anticipated impacts of
updated building energy codes for states, local governments and other
stakeholders.\2\

State Certification Statements
Section 304(b) of ECPA, as amended, requires each State to certify
to the Secretary of Energy that it has reviewed the energy efficiency
provisions of its residential building code and made a determination
whether it is appropriate to revise its code to meet or exceed the
provisions of the successor code. 42 U.S.C. 6833(a)(4). If a State
intends to certify that its residential building energy code already
meets or exceeds the requirements of the 2024 IECC, the State should
provide an explanation of the basis for this certification (e.g., the
2024 IECC is incorporated by reference in the State's building code
regulations). The chief executive of the State (e.g., the governor), or
a designated State official (e.g., director of the State energy office,
State code commission, utility commission, or equivalent State agency
having primary responsibility for residential building energy codes),
must provide the certification to the Secretary. For states that do not
have a statewide building energy code, the designated state official
must compile and submit a list of building energy codes in place across
units of local governments as part of the state certification.
State and Local Technical Assistance
The DOE Building Energy Codes Program tracks and reports State code
adoption and certification.\3\ DOE provides technical assistance to
states, as well as units of local government with authority to adopt
building energy codes, to assist them in evaluating building energy
code updates. This assistance is available by request and may include
technical analysis of expected energy code impacts, such as energy and
cost savings or environmental impacts, as well as evaluation of
proposed amendments, market trends, or other design and construction
data, as available. Following the adoption of an updated energy code,
DOE strives to provide technical assistance supporting the successful
implementation of such codes, including compliance tools, education and
training, and support for the updated code. DOE has issued previous
guidance on how it intends to respond to technical assistance requests
related to implementation resources, such as building energy code
compliance software. 79 FR 15112. The Bipartisan Infrastructure Law
(BIL) \4\ and Inflation Reduction Act (IRA) \5\ also provide
substantial assistance--over $1.2 billion in new Federal funding--
supporting adoption and implementation of updated building energy
codes. DOE does not prescribe how each State adopts and enforces its
energy codes.

Requests for Extensions
Section 304(c) of ECPA requires the Secretary to extend the
deadline for complying with the certification requirements described
previously, if a State demonstrates that it has made a good faith
effort to comply with such requirements and that it has made
significant progress toward meeting its certification obligations. 42
U.S.C. 6833(c). Such demonstrations could include one or both of the
following: (1) a plan to respond to the requirements in Section 304; or
(2) a statement that the State has appropriated or requested funds
(within State funding procedures) to implement a plan that would
respond to the requirements of Section 304 of ECPA. This list is not
exhaustive. States must send requests to the address provided in the
ADDRESSES section or submit them to [email protected].
