New Project Notification for Proposed Addenda to ACCA Manual S – 2023, Residential Equipment Selection
The Air Conditioning Contractors of America Educational Institute Standards Task Team has announced an American National Standards Institute project notification for a proposed addendum to ANSI/ACCA Manual S – 2023, Residential Equipment Selection.
The proposed Addendum “C” will correct and clarify certain requirements in the Normative Sections of ANSI/ACCA 3 Manual S – 2023, which includes Addendum “A” and “B” approved by ANSI in 2024.
ACCA Manual S provides specific procedures for selecting HVACR equipment against a set of ACCA Manual J loads and design conditions. Manual S uses original equipment manufacturer data and specifies how large or small the selected HVACR equipment capacity can be when compared to the load. For more details, visit acca.org.
The ANSI Project Initiation Notification System appeared in the ANSI Standards Action April 11, with a PINS response end date of Sunday, May 11. An ANSI public review draft is expected to be available for public comment following that period. Comments or questions can be submitted to David Bixby, ACCA’s manager of codes and standards, at david.bixby@acca.org.
