[Docket No. FR-6271-N-05]


Adoption of Energy Efficiency Standards for New Construction of 
HUD- and USDA-Financed Housing; Notice for Comment

AGENCY: Department of Housing and Urban Development (HUD) and 
Department of Agriculture (USDA).

ACTION: Notice; request for comments.

-----------------------------------------------------------------------

SUMMARY: HUD and USDA (``the agencies'') published a Final 
Determination on April 26, 2024, adopting the 2021 IECC and ASHRAE 
90.1-2019 energy codes as minimum requirements for programs covered 
under the Energy Independence and Security Act of 2007 (EISA). The 
Final Determination found that adoption of the energy codes would have 
no negative impact on the affordability and availability of EISA-
covered housing. The agencies plan to review the analysis contained in 
the Final Determination and are seeking public comments to inform the 
review.

DATES: Comment due date: August 6, 2025.

ADDRESSES: Interested persons are invited to submit comments regarding 
this rule. Communications must refer to the above docket number and 
title. There are two (2) methods for submitting public comments. All

I. Background

Statutory Requirements

    Section 481 of the Energy Independence and Security Act of 2007 
(``EISA,'' Pub. L. 110-140) amended section 109 of the Cranston-
Gonzalez National Affordable Housing Act of 1990 (Cranston-Gonzalez) 
(42 U.S.C. 12709), which establishes procedures for setting minimum 
energy standards for certain categories of newly constructed housing 
financed by HUD

and USDA. In addition to these EISA-specified categories, EISA also 
applies to new construction projects in the HOME Investment 
Partnerships Program (HOME) and the Housing Trust Fund program through 
their program statutes or regulations. Table 1 provides HUD and USDA 
programs covered by EISA:

    EISA references two standards: the International Energy 
Conservation Code (IECC) and American National Standards Institute/
American Society of Heating, Refrigerating, and Air-Conditioning 
Engineers/Illuminating Electrical Society Standard 90.1 (ASHRAE 90.1). 
The IECC standard applies to single family homes and multifamily low-
rise buildings (up to 3 stories), while the ASHRAE 90.1 standard 
applies to multifamily residential buildings with 4 or more stories. 
For both agencies, applicability is limited to newly constructed 
housing and does not include the purchase or repair of existing 
housing.
    The IECC and ASHRAE 90.1 are industry-based consensus codes that 
are typically updated on three-year cycles. Following each update, HUD 
and USDA are required to adopt the new versions of the IECC and ASHRAE 
90.1 within one year. If the agencies are unable to do so, the agencies 
must ``make a determination that the revised codes do not negatively 
affect the availability or affordability'' of the covered housing, and 
the Secretary of Energy must determine ``that the revised code or 
standard would improve energy efficiency'' in order for the agencies to 
consider adopting the updated versions of the IECC and ASHRAE 90.1.

Preliminary and Final Determination

    On May 18, 2023, HUD and USDA published a Preliminary Determination 
(88 FR 31773) that the 2021 IECC and ASHRAE 90.1-2019 did not 
negatively affect the affordability and availability of EISA-covered 
housing. After receiving feedback during the public comment period, the 
agencies published the Final Determination on April 26, 2024 (89 FR 
33112) with an updated economic analysis and found that adoption of the 
standards would not negatively impact the affordability and 
availability of EISA-covered housing.
    As outlined in Section I. F. of the Final Determination, changes to 
the

[[Page 29884]]

Preliminary Determination based on public comments included updated 
economic factors to reflect changes to the economic landscape due to 
the COVID-19 pandemic and global supply chain issues, adjustments to 
cash flow and financing factors to reflect typical financing factors 
for HUD and USDA borrowers, updates to the energy codes adopted at the 
state-level, more information on alternative compliance paths, and 
adjusted implementation and compliance timelines.
    The most significant update to the affordability analysis was the 
application of a supply chain cost increase factor of 37 percent and an 
energy price increase factor of 32 percent to reflect changes in costs 
following the underlying cost-effectiveness analysis published by the 
U.S. Department of Energy (DOE) in 2021. The supply chain cost increase 
factor was determined using the Bureau of Labor Statistics' Producer 
Price Index for inputs to residential construction less energy, as 
reported by the National Association of Home Builders (NAHB). The 
energy price increase factor was developing using data collected by the 
U.S. Energy Information Administration. More detail on these factors 
can be found in Sections I. F. and II. C. 4. of the Final 
Determination. Other updated economic factors included the energy price 
escalator, mortgage interest rate, and discount rate. Adjustments to 
cash flow and financing factors included revisions to the down payment 
rate, mortgage insurance premium, and home size.

Affordability and Availability Analysis

    HUD and USDA's affordability analysis considered several metrics of 
cost effectiveness, including life-cycle cost (LCC) savings, 
incremental cost, years to positive cashflow, and simple payback 
period, which combined to holistically assess affordability. More 
information on each of these metrics is available in the Final 
Determination. In the Final Determination, the affordability analysis 
is primarily presented through the various scenarios in tables 9 
through 20 for the 2021 IECC (89 FR 33137-33161) and tables 21 through 
29 for ASHRAE 90.1-2019 (89 FR 33164-33175). For the 2021 IECC, the 
analysis considers impacts at the national, climate zone, and state 
levels; a high-interest rate scenario; and different housing types. It 
also considers State adoption of energy codes. As of December 2023, 41 
states and the District of Columbia (DC) had adopted a version of the 
IECC that was equivalent to or higher than the prior HUD and USDA 
standard of the 2009 IECC. The remaining 9 states had either adopted 
standards that pre-date the 2009 IECC (1 state) or had no state-wide 
codes (8 states). See Table 11 of the Final Determination (89 FR 33147) 
for more information. As of December 2023, 33 states and DC had adopted 
an ASHRAE 90.1 standard that was above the prior HUD and USDA standard, 
while 17 states had adopted codes that were equivalent to or below the 
prior HUD and USDA standard or had no statewide codes. See Table 23 of 
the Final Determination (89 FR 33166) for more information.
    Tables 13 (89 FR 33153) and 19 (89 FR 33158-33159) in the Final 
Determination summarize the affordability analysis for adopting the 
2021 IECC in single family dwelling units, breaking down incremental 
costs by climate zone and by State. The agencies found the incremental 
cost of adoption to be $7,229, with incremental costs ranging from 
$3,662 to $8,845. Incremental costs for adoption of the 2021 IECC in 
those states currently at the 2009 IECC or its equivalent range from a 
low of $3,046 (Hawaii) to a high of $11,523 (Alaska), with most states 
typically in the $6,000 range.
    Additionally, Table 14 in the Final Determination (89 FR 33155) 
summarizes the affordability analysis for adopting the 2021 IECC in 
low-rise multifamily housing. The agencies found that the incremental 
costs for this housing type, as well as associated savings, are 
generally lower than for single family homes, as a result of both 
differences in unit size and building type. Incremental costs average 
$3,002/unit nationally.
    HUD and USDA also analyzed the cost effectiveness of adopting 
ASHRAE 90.1-2019 for mid- and high-rise buildings using methodology 
adopted by DOE. Tables 26 (89 FR 33171) and 27 (89 FR 33172) in the 
Final Determination provide incremental costs for a mid-rise 
multifamily prototype building in various climate zones and for each 
State. The agencies found that the national average additional 
construction cost of adopting the ASHRAE 90.1-2019 is $574 per building 
or $18 per unit. In some areas, construction costs were estimated to 
decrease because the updated code allows for smaller and fewer fixtures 
and appliances. Overall, given LCC savings and potential decreases in 
construction costs, the agencies determined that the adoption of ASHRAE 
90.1-2019 would not negatively impact the affordability of the 
multifamily housing.
    The agencies also determined that adoption of the 2021 IECC and 
ASHRAE 90.1-2019 would not negatively impact the availability of 
covered housing. Availability of housing is a measure associated with 
whether builders will make such housing available to consumers at the 
higher code level; i.e., whether the higher cost per unit as a result 
of complying with the revised code will impact whether that unit is 
likely to be built or not. The Final Determination, along with the 
accompanying Regulatory Impact Analysis (RIA), looked at various 
availability scenarios and determined that availability would not be 
negatively affected.

Delayed Compliance Dates

    On March 10, 2025, HUD published a notice delaying outstanding 
compliance dates by six months for HUD programs (90 FR 11622). On April 
4, 2025, USDA similarly published a notice delaying compliance dates 
for USDA programs by six months (90 FR 14775). The extension was 
intended to provide additional time for HUD and USDA to review 
questions of fact, law, and policy supporting the Final Determination 
and determine the need for HUD to develop further technical assistance. 
For compliance dates that had already gone into effect, such as the 
HOME Investment Partnerships program and Housing Trust Fund program, 
HUD encouraged entities struggling to meet the requirement to contact 
HUD.
    To allow for more flexible compliance with the 2021 IECC and ASHRAE 
90.1-2019 requirements, HUD and USDA adopted a list of acceptable 
alternative compliance paths for certifications that meet or exceed the 
energy efficiency of the adopted standards. These alternative 
compliance path options include specific versions of the Environmental 
Protection Agency's ENERGY STAR program and DOE's Zero Energy Ready 
Homes program; third-party high performance building standards 
including Enterprise Green Communities, LEED, National Green Building 
Standard, Phius, Passive House Institute, Earth Advantage, Earthcraft, 
Living Building Challenge, Pearl Certification, Green Globes, BREEAM, 
and GreenPoint Rated; and the 2024 IECC and ASHRAE 90.1-2022. The 
agencies received multiple public comments from various stakeholders 
that specifically requested the 2024 IECC be accepted as an alternative 
compliance path. The full list of alternative compliance paths is 
available by request at [email protected].

    HUD and USDA are considering reexamining the analysis in the Final 
Determination and are seeking public comment to inform a potential 
review, consistent with the Executive Action, ``Delivering Emergency 
Price Relief for American Families and Defeating the Cost-of-Living 
Crisis.'' The public has had time to begin planning and implementing 
the Final Determination's requirements. With that perspective, HUD and 
USDA would like to better understand how the adoption of the updated 
codes is working in practice. The agencies welcome comments on any 
aspect of the Final Determination and also specifically seek comments 
on the following matters.
    1. In the Final Determination, HUD and USDA updated several 
economic and cash flow factors. The affordability analysis included in 
the Final Determination reflected the economic landscape around the 
time of publication. Have any of these factors changed since the 
publication of the Final Determination? If so, which specific economic 
factors should be reconsidered and how are they different from the 
analysis included in the Final Determination?
    2. As of April 17, 2025, nine states have adopted the 2021 IECC and 
15 states have adopted ASHRAE 90.1-2019 based on DOE's State Energy 
Code Adoption map. For builders and developers operating in States that 
have already adopted the 2021 IECC or ASHRAE 90.1-2019, are you facing 
any challenges to implementing these building codes?
    3. The agencies are interested in feedback from builders who are 
already building to higher energy performance standards listed on the 
alternative compliance paths list. What advantages or disadvantages 
have you seen in the construction of higher performance homes? Please 
be specific as to the type of housing--owner-occupied single family or 
entity-owned multifamily rental housing.
    4. The agencies seek to provide builders with the most flexibility 
in meeting current baseline energy performance measures. This includes 
the list of alternative compliance paths, which responds to the public 
comments of industry that the IECC 2024 is a preferred code for 
builders and it meets or exceeds IECC 2021. The agencies seek to keep 
this list of alternative compliance paths updated as industry evolves. 
What other codes or standards are builders and industry aware of beyond 
the list of proposed alternative compliance paths that meet or exceed 
the baseline of IECC 2021 that are active in markets and ready for 
inclusion in the list of alternatives?
