ARLINGTON, Va. — The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) announced an American National Standards Institute (ANSI) third public review period for a new standard, “Existing Home Evaluation and Performance Improvement.” This third public review period will close at 5 p.m. Eastern Time on Dec. 4, 2011.

ACCA said that, due to the limited number of revisions to the standard for this public review, the revisions are presented in a two-page table. Only the revisions in these two pages are subject to review and comment. The table indicates changes to the proposed standard via underline (for additions) and strikethrough (for deletions) along with the rationale for the change.

The proposed standard identifies the metrics, tolerances, approved procedures, and required documentation to (1) evaluate the current performance, (2) establish the basis to create performance improvement specifications, (3) identify approved approaches to implement the specified improvements, and (4) establish the procedures to objectively assess the performance change of the completed improvements.

This standard is referenced as BSR/ACCA 12 QH - 201x (Existing Home Evaluation and Performance Improvement) and the required response form can be downloaded at Comments must be submitted on the response form in accordance with the instructions on the form.
