NFRC Ballots for the Mid-Cycle meeting, July 13, 2020

Posted By Adriana Vargas, National Fenestration Rating Council, Monday, June 22, 2020

Ratings Committee

 1.       NFRC 700 Glazing Description

The purpose of this ballot is to change the required information for the temporary label on certified products.

  • The change makes all the glazing description optional instead of mandatory.
  • The number of glass panes has also been added to the text describing the glazing description.
  • The tint colors also have been incorporated into the single glazing description paragraph.
  • Manufacturers that currently print a glazing description on their label may continue to do so.
  • There are no required or mandatory changes that a manufacturer must make to their labels as a result of this ballot.

2.       NFRC 700 Condensation Index

The purpose of this ballot is to remove the NFRC 500 Condensation Rating and replace it with the ANSI/NFRC 500 Condensation Index.

  • Implementation will not take place until the LEAFF pilot program is completed in late 2020.
  • PCP participants that want to utilize the NFRC 500 Condensation Resistance Rating in certification authorizations can do so until the implementation of the ANSI/NFRC 500 Condensation Index and implementation or publication in the NFRC 700 PCP.
  • Implementation of the Condensation Index will require modification to the Certified Products Directory.

Technical Committee

 1.       ANSI/NFRC 100 Reporting Ratings

The purpose of this ballot is that ANSI/NFRC 100 is corrected to strike any reference to report metric U-factor to the nearest .05 W/m2K and strictly use proper rounding of the result to two decimal points.

  • Per NFRC 700, there is no language that states metric rating of U-factor shall be rounded to the nearest 0.05 W/m2K but, consistently throughout the document it states that the U-factor rating shall be displayed on the NFRC label as rounded to two decimals.
  • The sample labels confirm that the metric U-factor is not required to be rounded to the nearest 0.05 W/m2K as shown in Figures A-5 and A-9.
    • The U-factor in those sample labels show a metric U-factor of 1.99 W/m2K and is confirmed to match the I-P (Imperial) value of 0.35 Btu/hr/ft2/F.
    • The conversion is calculated, as required by NFRC 700, as 5.678263.
    • This conversion is the value used by the laboratories when converting metric to I-P in their reports as well as the CPD 2.0 Upload Spreadsheet.
  • 2.       ANSI/NFRC 100 Spandrel

    The purpose of this ballot is to add language to include the simulation of all spandrel panel systems to the NFRC program.

    • The Spandrel Validation Task Group has met a few times to address all questions and negative comments from the NFRC Fall Membership Meeting in Charlotte in 2019.
    • Previously, spandrel glass only was able to be simulated, which has always been a limitation to the NFRC program for commercial manufacturers of glazed wall systems. 
    • Research was conducted and presented at the NFRC Fall Membership meeting in Albuquerque in 2018 that proved that spandrel systems with interior opaque metal insulation panels can be simulated and backed up by validation testing.
    • The conclusions of the research indicated that more than 63.5mm of glass edge is required and that 254mm of glazing edge shall be required for an accurate simulation.
    • The simulation methodology shall be presented to TIPC for their review and approval and inserted into the Simulation Manual upon approval of ANSI/NFRC 100.

    3.       ANSI/NFRC 200 Equation 4-3

    This correction to NFRC 200 will make any work done for the LEAFF program consistent with the calculations WINDOW has always used.

    • During the work to move forward with the LEAFF program, it was discovered that the exterior heat transfer coefficient in Equation 4-3 was in error. 
    • The value of 30 W/m2K in the equation is for the winter conditions and the SHGC is calculated under summer conditions.
    • The WINDOWS program from LBNL has always used the summer exterior heat transfer coefficient of 20.6 W/m2K.

    4.       ANSI/NFRC 200 Spandrel

    This is the second ballot to add language to include the simulation of all spandrel panel systems to the NFRC program. 

    • Previously, spandrel glass only was able to be simulated and that has always been a limitation to the NFRC program for commercial manufacturers of glazed wall systems. 
    • Research was conducted and presented at the NFRC Fall Membership meeting in Albuquerque in 2018 that proved that spandrel systems with interior opaque metal insulation panels can be simulated and backed up by validation testing.
    • The research findings indicated that more than 63.5mm of glass edge is required and that 254mm of glazing edge shall be required for an accurate simulation.
    • The simulation methodology shall be presented to TIPC for their review and approval and then inserted into the Simulation Manual upon approval of ANSI/NFRC 100.

    5.       ANSI/NFRC 500

    This ballot is to make further refinements to the new Condensation Index procedure and to also address some comments that came from NFRC's ANS Committee.

    6.       NFRC 501

    This ballot is to change the reference to the distance the glass edge temperature is to be taken. 

    • All documents and the software tool referencing the Condensation Index shall have consistent language that the glass edge temperature shall be obtained at 25mm and not 25.4mm.  
    • Only section 1.2 of NFRC 501 is shown with Underline/Strikeout for balloting.


    Research and Technology Committee

     1.       NFRC 101 Appendices

    This ballot is intended to update the source references for the material properties listed in Appendices A and B and to update the properties based on those new references.

    • This is a follow up to the ballot from the Virtual Spring Committee 2020 meeting.
    • The changes marked in this ballot are the last remaining changes that had negative comments associated with them from the previous ballots.
    • All other changes have been approved from the previous ballots.

    Staff does not anticipate any additional document changes, no legal review, or additional cost for implementation. The default THERM materials library will be revised to incorporate the changed Appendices after final approval of the document.

    • The implementation plan suggested by the task group is for the new appendices to be used no earlier than Jan. 1, 2021.
    • Once implemented, the new data shall be used for all new certifications, revisions, and addenda to existing product lines.
    • All existing product lines and products in the CPD at the time of implementation will be able to remain until the end of the certification cycle for that product line.

    2.       NFRC 101 Non-homogenous Spacer

    This ballot revises Section 5.1.7.2 relating to conductivity measurements of non-homogeneous spacer samples. Four changes are proposed:

    • An upper limit on the thickness of the foam rubber sheets.
    • Test method revisions based on the laboratory equipment capability
    • Specifying the removal of the contribution of the glass to the thermal resistance of the specimen
    • Clarifying the reference to EN675.

    New Board Chairman Sees Member Involvement as Essential for Long-Term Growth of NFRC

    Posted By Adriana Vargas, National Fenestration Rating Council, Monday, April 27, 2020
    Updated: Tuesday, April 28, 2020

    A conversation with John Gordon

    When he was an on-demand, round-the-clock information technology consultant, John Gordon knew that when a computer system went down, there was no waiting until tomorrow. That sense of urgency is real, and you don’t go home until the system is back online. Today, as the newly elected chairman of the NFRC Board of Directors, John embodies that same level of commitment to ensure the organization operates smoothly, without disruption.

    After leaving IT, John transitioned to become the Simulation and Thermal Operations Manager and a certified simulator at National Certified Testing Labs based in York, PA. He oversees testing and ensures accurate ratings for product certification, which leads to certification labeling. His department is responsible for the NFRC testing, so it goes without saying that John knows the importance of the label. In his six years of being involved with NFRC, John’s held a variety of positions ranging from participating in task groups to leading committees to chairing working groups.

    To mark the beginning of his tenure as board chairman, Michelle Blackston, senior director of communications and marketing, spoke with John about his vision for the board and the organization as well as goals he’d like to accomplish during his term.

    What do you hope to accomplish while leading NFRC’s board of directors and overseeing the organization for the next two years? Also, talk about your leadership style and how you will set the direction for the future of NFRC.

    It’s imperative that we continue stressing the importance of NFRC’s fair, accurate, and credible ratings for the growth of the organization, both in membership and for the widespread use of the NFRC ratings label. As board chair, I will also advocate for the use of NFRC ratings in the ever-expanding green building initiatives. This is especially vital for the health and betterment of the organization. Additionally, it bodes well for the fenestration industry overall, including our members.

    I believe leadership is extremely important and so is the diversity of the board to have a voice. There are so many intelligent minds in the organization and on the board. Everyone has an opportunity to be involved with NFRC, and that’s the key to the success of the overall direction and health of the organization. I’m a big proponent of people getting involved and using their voice and vote to bring about change.

    Over the last 30-plus years, NFRC has grown and evolved. What do you see as some of the biggest changes with NFRC? What is on the horizon for the organization and in the fenestration industry?

    The movement in the organization to accredit the Product Certification Program (PCP) is extremely important for its long-term sustainability. I’ve seen a shift to be more open within the organization to embrace change such as in the new Linear Energy Analysis for Fenestration or LEAFF methodology.

    From a high-level view, we need a better way to anticipate the pitfalls or the risks that lie ahead. We need some type of mechanism to determine risk and then capture, respond, and react. Ideally, we need to make ourselves immune to the risks.

    Also, we need local and state code officials to rely on NFRC ratings. The ratings and the data that NFRC is known for and has expertise in must be a prominent part in the green building and wellness industries. Coming full circle, the more that starts to happen and the more exposure of the NFRC label, then there will be a drive for more companies to see the benefits of membership and being involved.

    As for the industry, wellness and green initiatives are becoming more prominent along with the continued drive for more energy-efficient products. Both of those being in the discussion for net positive energy. However, we’re in a space and time where we’re asked to do more with less, which – before the Coronavirus and these stay-at-home orders – turns into more hours in the workspace. And the human element of comfort needs to be included in building facades and envelopes. Unless your building is actual brick and mortar there is no way fenestration can’t be a part of it.

    What lessons have you learned from being involved in NFRC that you would share with young professionals just getting started in the fenestration industry?

    Get involved. Be engaged. Listen. Actively participate—ask questions and offer ideas. NFRC is a great, well-rounded group of people and minds coming together to promote the advancement of energy efficiency, home and work environment comfort by way of fenestration products.

    Through my time with NFRC, I’ve experienced tremendous technical growth and been able to connect and collaborate with some great individuals within the industry. As someone coming from a different sector or industry, I’ve been impressed by the minds in those meetings. There hasn’t been a meeting where I haven’t walked away without learning something or expanded my rolodex of people who I can call as a resource. 

    If you could do anything now (outside your current profession or role), what would you do?

    I would be professionally involved in sports in some way. I’d love to be an advanced scout or working in the front office of a professional sports team. I like to play baseball and ice hockey, and I enjoy coaching baseball. Mostly, I just want to be outdoors, enjoying my time with nature.
