The Code Council partners with ACCA and RESNET  

WASHINGTON, D.C. — The International Code Council has partnered with the Air Conditioning Contractors of America (ACCA) and the Residential Energy Services Network (RESNET) to develop the ANSI/RESNET/ACCA/ICC 310-2020 Standard for Grading the Installation of HVAC Systems.

The new standard is the product of a collaborative effort of the three organizations that establishes the procedures, tolerances, and record keeping practices for evaluating and grading elements of an HVAC system’s design and installation.

The standard provides a pathway to earn an improved Energy Rating Index (ERI) score when the heating and cooling system is installed in compliance with its published requirements. The Standard applies to Unitary HVAC systems and 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 noninvasive evaluation of refrigerant charge. Designed to be completed in sequence, the results of each task are evaluated for compliance with specified thresholds including design tolerances and installation quality.

The Code Council has held long-standing partnership with both RESNET and ACCA, which include a special certification designation and membership agreement.
