Stops the NFRC Meeting
While USGNN covered the NFRC meeting
last week, we did not get a chance to explain some of the controversy
that occurred toward the end of the meeting.
A revote temporarily halted proceedings at the National Fenestration
Rating Council's (NFRC) summer meeting last week came, during the
meeting of the Component Modeling Approach (Rating) subcommittee.
In discussing, NFRC CB-PCP-2006: Component-Based Fenestration Product
Certification Program, Michael Thoman with Architectural Testing
Inc. motioned that the term "approved calculation entity,"
referred to throughout the document as "ACE," be changed
to "accredited calculation entity."
An approved calculation entity calculates the energy indices for
fenestration systems using NFRC-approved procedures and the component
library database. Such a change would have limited the types of
entities that could have been called ACEs.
According to Max Perilstein, with Arch Aluminum and Glass, keeping
the word "approved" allows for the possibility of having
the manufacturer or end user involved in the process. Because of
the way "accredited" was defined in the NFRC Laboratory
Accreditation Program (LAP), as only applying to laboratories, changing
the word from approved to accredited could potentially lock out
anyone except for "accredited labs."
Thoman added that the definition of accreditation included in the
NFRC glossary (which was also being balloted at the meeting) could
be changed to not be laboratory-specific. After a vote, the motion
A second motion, to specifically use the term "approved calculated
entity" throughout the document, rather than the abbreviation
However, following the voting process, Thoman suggested that the
official procedures for voting had not been correctly followed throughout
the meeting, and asked for a revote of the failed motion. Following
a lengthy discussion with the council's lawyer over voting procedures,
the vote was retaken, with one vote having changed; the revote upheld
the original decision to keep the term "approved," rather
