ANSI Public Review of Proposed Revisions to ACCA Manual S®
The ACCA Educational Institute's Standards Task Team (STT) announces an American National Standards Institute (ANSI) public review period for proposed revisions to ACCA Manual S, Residential Equipment Selection, as a revised industry standard. The 45-day ANSI public review period started on November 25, 2022, with a comment deadline of January 9, 2023. The proposed standard is a revision of ANSI/ACCA Manual S – 2014. The standard provides procedures for selecting and sizing residential heating, cooling, dehumidification, and humidification equipment. The standard is divided into two parts – a “Normative” portion that details the selection/sizing criteria and an “Informative” portion that provides discussion, guidance, and example problems related to procedure intent and use. The public review draft only involves proposed revisions to the Normative sections, which are Section N1 – Definitions and General Requirements; Section N2 – Equipment Size Limits; and Section N3 – OEM Verification Path. The red-line review draft can be obtained by sending a request to firstname.lastname@example.org. Comments should be submitted to the same address.
Member Input Needed – ACCA Reviewing Several of its ANSI Recognized Standards for Potential Updates
ACCA has begun the process to review several of its current standards that are recognized by the American National Standards Institute (ANSI). According to ANSI’s Essential Requirements, once a standard is approved it must be reviewed every 5 years to determine whether it requires (a) additional changes or updates, (b) reaffirmation if no changes are needed, or (c) withdrawal.
A description of each standard under review is shown below.
