This can be seen by the fact that the Single Family New Homes (SFNH) <strong>switched from version 3.1 to version 3.2 this year for the <a href=\"https:\/\/leyton.com\/us\/energy-efficiency-incentives\/45l-energy-efficient-home-tax-credit\/\"><mark class=\"has-inline-color has-green-color\">45L tax credit<\/mark><\/a>.<\/strong> Similarly, version 1.3 of the Multifamily New Construction (MFNC) has been <strong>released along with SFNH version 3.3.<\/strong>&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Along with the release of the new versions of Energy Star, new revisions were made to all major program documents including the National Rater Checklist and National Design Review Checklist. Generally, the revisions are used to add clarity to specific requirements and tweak the checklist for smoother implementation of the program requirements. However, this round of revisions, released on January 15<sup>th<\/sup> 2025, made some large changes that fundamentally alter how the program will operate going forward.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Below is a review of some of the most impactful changes that SFNH Revision 14 and MFNC Revision 5 introduced. Go to the <a href=\"https:\/\/www.energystar.gov\/partner-resources\/residential_new\/program_reqs\/policy_record?qt-policy_records_single_family_tab=1#tab-1\" target=\"_blank\" rel=\"noreferrer noopener\"><mark class=\"has-inline-color has-green-color\">Energy Star Policy Record<\/mark><\/a> to see all the changes of the new revisions. <strong>The newest revisions can be used starting now but will be required for projects starting in 2026. <\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Big Changes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the biggest changes to both programs was made to section 3 of both National Rater Checklists. <strong>Section 3 Reduced Thermal Bridging required advanced framing techniques<\/strong> if continuous insulation was not installed, as well as<strong> slab edge insulation had to be installed in Climate Zones 4 and up.<\/strong> Both the SFNH and MFNC programs have made those requirements optional, though they still need to be inspected on site. While Section 3 is no longer required, it is still recommended since the items within help the project meet the UA requirement of the program version they are pursuing. UA measures a dwelling unit\u2019s total thermal efficiency across the entire envelope. Rather than being required to construct specific building details, builders now have more options to meet program requirements.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another important change introduced with the new revisions is changing what and how builders can verify National Rater Checklist items. Builders may verify or partially verify only 5 items now, down from 8. Partial verification allows builders to verify part of an item so long as they meet the requirements outlined in the National Rater Checklist. The Water Management Checklist has been sunset in the new revisions since it was not required for 3<sup>rd<\/sup> party verification. &nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are several other important changes to be aware of. <strong>Townhomes are no longer eligible for the MFNC program<\/strong> and will be eligible only through the SFNH program. <strong>There are no longer window U-value requirements<\/strong> as it is now wrapped up in total UA requirements. Finally, <strong>local exhaust ventilation cannot be separated from the room they are meant to serve with a door.<\/strong> That means the fart fan in the water closet can no longer satisfy the local bathroom exhaust ventilation requirement.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are many other small changes and clarifications that were introduced in the new revisions. However, they seem to be all similarly aligned in giving builders more flexibility on how they meet program requirements. The revisions continue to further Energy Star\u2019s goals of creating quality, energy efficient and healthy homes.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Leyton Can Help<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Leyton\u2019s team of tax experts, engineers, and Energy Star raters can help make sure you maximize your project potential.
