Interim Addendum 64i currently authorizes use of criteria for inspection and test sampling in the RESNET Guidelines for Multifamily Energy Ratings after compliance with Standard ANSI/RESNET/ICC 301-2019 became mandatory January 1, 2022. Standard ANSI/RESNET/ICC 301-2019 supersedes all other requirements of the Guidelines after the January 1, 2022, Mandatory Compliance Date. The Guidelines’ inspection and test sampling criteria will be used for Sampled Ratings of multifamily Dwelling Units until the MINHERS Chapter 6 has been updated to explicitly address sampling for multifamily ratings. Proposed Addendum 64f will be the final version of Addendum 64 when completed. The Addendum also extends expiration of the current exception for leakage testing created for Puerto Rico and the US Virgin Islands after Hurricane Maria from 2022 to 2024.
