Proposed Addendum 34 amends the RESNET Mortgage Industry National Home Energy Rating Standards minimum requirements for the QA Data File. There is currently only the generic definition for Quality Assurance Data File which does not establish a minimum acceptable threshold for the data that must be furnished to the provider and maintained by the provider for 10% File QAs. The proposed addendum identifies what a QA Data File must include as a minimum and is intended to improve the consistency, transparency, and effectiveness of File QAs. RESNET Standard Development Committee 900 approved draft PDS-03 of Addendum 34 for public review and comment. Changes to draft PDS-02 shown in draft PDS-03 by strike-through/underline text in red print are open for comment. Public comments will be accepted through April 22, 2020. The draft addendum, comment form, and comments submitted to date are posted at Draft PDS-03 of proposed Addendum 34: QA Data File. After the comment period, the SDC 900 will consider and document each of the comments submitted and make appropriate changes. Substantive changes will be submitted for public comment.
