The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) announces American National Standards Institute (ANSI) approval for ANSI/ACCA 12 QH – 2024, Home Evaluation and Performance Improvement, as a revised industry standard. 

ACCA’s ANSI-approved quality standards have been adopted by utilities, government agencies, manufacturers and others nationwide because these are the only standards that show how to make building truly energy efficient while ensuring occupant comfort.  

ANSI approved the revised standard on September 26 after a 30-day ANSI public review period. The proposed revisions were to resolve comments received during the proposed reaffirmation of 12 QH which was announced for ANSI public review on January 5.  

The 12 QH Standard establishes minimum requirements to evaluate a residence regarding energy efficiency, water conservation, occupant comfort, and indoor air quality. From this evaluation, improvement opportunities are presented to the customer by a design practitioner so they can select improvements that meet their needs.

ACCA makes these standards available as a service to the industry and the broader community. All of the ACCA Quality Standards are available on the ACCA website.
