Public Comment on Draft PDS-02 of BSR/RESNET/ACCA 310- 20xx

Mar 24, 2020

Proposed Standard BSR/RESNET/ACCA 310-20xx, Standard for Grading the Installation of HVAC Systems establishes a methodology for evaluating the installation quality of Unitary HVAC systems. It establishes the procedures, tolerances, and record keeping required to evaluate elements of an HVAC System’s design and installation.

The methodology is comprised of five tasks – a design review, a total duct leakage test, a Blower Fan volumetric airflow test, a Blower Fan watt draw test, and a non-invasive evaluation of refrigerant charge. The five tasks are designed to be completed in sequence and upon completion of each task, the results are evaluated for compliance with specified thresholds.

Public comments on draft PDS-01 of the proposed new standard were considered by RESNET SDC 300 and the resulting changes have been incorporated in draft PDS-02. The changes to draft PDS01 are submitted for public comment. Public comments will be accepted March 20, 2020, through May 4, 2020. The draft standard, comment form, and submitted comments are posted at Draft PDS-02, BSR/RESNET/ACCA 310-20xx
