Day 2 of Virtual Meeting Starts with Software Subcommittee Meeting

The second day of NFRC’s Summer 2010 Virtual Committee Week kicked off with the Software Subcommittee meeting under the Technical Committee Block.

After Subcommittee Chair Brian Crooks, of Cardinal Glass Industries, Inc., welcomed participants, Joe Hayden, of Pella Corp., presented a motion on behalf of the WINDOW 6/THERM 6 Approval Task Group for an interim, partial approval of W6/T6.

The subcommittee passed a motion to approve the task group’s recommendation, as indicated in a June 1, 2010, letter to the NFRC membership. The letter noted that the “primary reason for this proposal is compatibility with the Component Modeling Approach (CMA) Software Tool, to avoid maintaining two different version of the WINDOW/THERM software.”

The task group’s proposal to partially implement W6/T6, and subsequently sunset W5/T5 on December 31, 2010, applies to simulation of only those products that can currently be simulated with W5/T5, in accordance with current NFRC procedures. The task group’s proposal also requires web-based training for certified simulators and IAs in August and September 2010 (and that no simulator shall use W6/T6 for NFRC certification services until they have successfully completed the training).

The motion, which applies to version 6.3 for both software programs, now moves forward to the Technical Committee for further consideration.
