Proposed Standard BSR/RESNET/ICC 301-2022 Addendum B-202x amends the 2022 edition of Standard 301 to modify the criteria for calculation of the CO2e Index. The CO2 Index was established by standard ANSI/RESNET/ICC 301-2019 Addendum D which was then incorporated into Standard 301-2022 along with other Standard 301-2019 addenda. New versions of the databases referenced by Standard 301-2019 Addendum D were released after it was approved so the Index calculation sections are being revised by BSR/RESNET/ICC 301-2022 Addendum B-202x to update the references and clarify their use. (Note: Standard 301-2019 recently became the basis for calculating RESNET HERS® Index ratings so Standard 301-2022 will not become the basis for the HERS® in the near term. MINHERS® Addendum 66 adopted the CO2e Index calculation and reporting criteria currently in effect for the HERS® including the updated referenced databases so the Index will be calculated and reported with the HERS® ratings when rating software is updated. Standard 301-2022 Addendum B is intended to ensure that the criteria for the CO2e Index calculation are consistent with the criteria adopted by the MINHERS® Addendum 66 when the transition to the Standard 301-2022 based HERS® occurs in the future. Also note, the CO2e Index calculation utilizes data currently collected by raters and does not require additional data collection.)

Comments on portions of draft PDS-02 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.
