RESNET and the International Code Council to Adopt Joint ANSI Standard on Testing of Air Leakage, Duct Leakage and Airflow of Mechanical Ventilation Systems

June 2nd, 2015 - Posted by Laurel Elam under RESNET News


The International Energy Conservation Code (IECC) now requires air leakage and duct testing of homes.  The IECC, however, does not specify the procedures on how these tests are to be completed.  To provide guidance to code officials on how such tests should be conducted, the International Code Council (ICC) and RESNET are developing a joint American National Standard (ANSI) standard.

The new ANSI standard will be based on the draft BSR/RESNET/ICC 380-201x PDS-02 that was developed by the RESNET Standard Development Committee 300. This proposed draft standard has undergone two public review and comment periods and is in the final stages of adoption.

The adoption of ANSI/RESNET/ICC 380 will provide code officials with an American National Standard that they can specify for air and duct leakage testing in their code jurisdictions.  It will also help ensure greater consistency in compliance to energy codes.

The International Code Council (ICC) is a member-focused association. It is dedicated to developing model codes and standards used in the design, build and compliance process to construct safe, sustainable, affordable and resilient structures. Fifty states and the District of Columbia have adopted the ICC’s International Codes (I-Codes) at the state or jurisdictional level.  The ICC develops the International Energy Conservation Code (IECC).
