Committee Votes to Not Allow AAMA 507 as NFRC Alternative
The IECC code change proposal EC4 was disapproved during code hearings
this week in Minneapolis. If approved, EC4 would have allowed for
the use of AAMA 507 for rating curtainwall and storefronts an alternative
to NFRC 100 and 200.
Proponents included Craig Conner, Building Quality, representing
himself; Julie Ruth, JRuth Code Consulting, representing AAMA; Rand
Baldwin, Aluminum Extruders Council; Margaret Webb representing
the Insulating Glass Manufacturers Association; and Greg Carney,
representing the Glass Association of North America.
According to hearing documents, the committee voted to disapprove
the proposal, as it did not include third-party oversight requirements
for manufacturers doing the determination of the fenestration ratings.
The committee also said the standard was unclear regarding who should
be qualified to do the fenestration rating calculations.
