Draft PDS-01, BSR/RESNET/ICC 301-2019 Addendum C-202x

Proposed addendum BSR/RESNET/ICC 301-2019 Addendum C-202x will revise Standard ANSI/RESNET/ICC 301-2019 to allow the use of default values for Duct Leakage to Outside (DLTO) when values are not determined by test. An earlier iteration of the RESNET HERS allowed default DLTOs but defaults were not carried forward into the first edition of Standard 301. SDC 300 proposes adding defaults to Standard 301-2019. Addendum C also includes changes to Table 5.1.2(1) that revise emission values for household fossil fuels and includes a clarification of how glazing in a door that represents < 50% of the door rough opening is to be modeled.

This first draft of proposed Addendum C is submitted for public comment for 45 days, beginning September 17, 2021 and ending November 1, 2021. Only the changes shown by strike-through and underline text in red print are open for comment. To review and comment on the Draft follow the links below.

Tips and Reminders for Submitting Public Comments 

  • Comments must pertain to text in draft PDS-01 that is shown as either strikethrough or underlined and red print. Comments on portions of draft PDS-01 where no change is indicated will be rejected.
  • Comments must include a specific proposed change to the text of the draft open for comment. Proposed added text must be underlined and text proposed to be removed must be shown using strike-through. If not submitted in this format, the public comment may be rejected.
  • Do not submit comments on standards other than this one that is out for public comment.
  • If you submit public comment representing the collective interests of a group of stakeholders, you are encouraged to submit ONE public comment and identify all stakeholders in that comment. While not required, this expedites the ability of the committees to respond to commenters in a timely manner.
  • Public comments are reviewed by committees with volunteer members, that are Raters, Providers, Software Developers and other industry and public interest stakeholders. They are not reviewed by RESNET Staff.
  • Most amendments to RESNET standards are proposed by industry and public stakeholders not RESNET. To learn more about submitting proposed amendments visit this page:https://www.resnet.us/about/standards/submit-proposed-amendments/
