The RESNET Standard Development Committee (SDC) 300 has authorized the release of BSR/RESNET/ICC 301-2014 Addendum D-201x, PDS-01 “Testing Airtightness of Building Enclosures, Airtightness of Heating and Cooling Air Distribution Systems, and Airflow of Mechanical Ventilation Systems: Reference Standard ANSI/RESNET/ICC 380-2016” to the RESNET ANSI consensus standard amendment public review and comment process. Currently ANSI/RESNET/ICC Standard 301 refers to the RESNET Mortgage Industry National Home Energy Rating Standards for the procedures for conducting air-tightness and duct leakage testing. The ANSI/RESNET/ICC Standard 380 on “Testing Airtightness of Building Enclosures, Airtightness of Heating and Cooling Air Distribution Systems, and Airflow of Mechanical Ventilation Systems” has since been adopted as a national consensus standard. This proposed amendment will change the reference in the ANSI/RESNET/ICC Standard 301 to the ANSI/RESNET/ICC Standard 380. RESNET will accept public comments on preliminary draft addendum, PDS-01 of BSR/RESNET/ICC 301-2014 Addendum D-201x, Testing Airtightness of Building Enclosures, Airtightness of Heating and Cooling Air Distribution Systems, and Airflow of Mechanical Ventilation Systems: Reference Standard ANSI/RESNET/ICC 380-2016, beginning July 29, 2016.
