Technical Subcommittee Meetings Continue

The Technical Committee block continued Wednesday morning with the Annual Energy Performance (AEP) Subcommittee and CMA Technical Subcommittee.

AEP Chair Tom Culp of Birch Point Consulting, LLC, explained that earlier this year the group passed NFRC 901, which is a calculation procedure for analyzing the fenestration products in private homes. Although it’s available for use, implementing it will require further refinements such as a Web tool to make it easy for consumers.

“As it stands right now this is something that has limited usefulness,” said NFRC Chair Joe Hayden. “Nevertheless, it’s a step in the right direction.”

Certain members expressed concern with creating a viable plan for moving forward on developing a single set of parameters to develop a single set of numbers for NFRC 901.

Culp responded saying there are only a few key issues standing in the way of accomplishing this, and he believes they can be overcome relatively easily.

During the CMA Subcommittee meeting, four ballots were up for discussion, including Validation Testing, Frame Grouping, and Non-Standard Products for NFRC 100 and 200. The CMA Validation Testing ballot negatives were addressed and several motions were brought forth. Curcija motioned to remove the upper limit of U-Factor of .35 for an insulated glazing unit.

“Because of the timing, we should get something in the document now rather than waiting until next March,” said Culp, speaking against the motion.

The motion did not carry.

After much debate, the Validation Testing and Frame Grouping ballots were resolved and moved forward to the Technical Committee. The Non-Standard Products – NFRC 100 and 200 ballots were sent back to the task group.
