Chair's Corner


Welcome to our Summer Newsletter! We recently concluded another outstanding Membership Meeting and I want to extend many thanks to our guest presenters, sponsors, and staff for a smooth and enjoyable meeting. I also want to touch on some of the major recently completed and ongoing CRRC projects.

At every Annual Membership Meeting, we hold elections for the CRRC Board of Directors. The 2016 election put forth many great candidates and I want to thank all of you who sought election. I also want to thank outgoing Director Jim Hoff (Center for Environmental Innovation in Roofing) for his service over the last six years. I also want to welcome new Director Payam Bozorgchami (California Energy Commission).

Another Membership Meeting feature is the announcement of the recipient of the Marty Hastings Award for service to the CRRC that goes above and beyond the call of duty. This year Ronnen Levinson is being recognized for his outstanding efforts in test method development and validation, as well as overall support and significant time dedicated to the Board of Directors and Technical Committee.

Additionally, an outline of the process to develop an online application system to benefit our members by improving and streamlining the product rating process was presented at the  Membership Meeting, as well as an update on the 2016 edition of ANSI/CRRC S100 (formerly CRRC-1 Standard). The public review process to update the standard was completed this year, in time for inclusion in the next update of the International Energy Conservation Code and ASHRAE 90.1. Many thanks to Sarah Schneider and Jonathan Humble for their leadership in making this happen.

Ratings, Codes, and Programs

2016 Edition of ANSI/CRRC S100 Standard

The CRRC is proud to announce that the three year process to update the ANSI/CRRC S100 (formerly CRRC-1 Standard) was recently completed in accordance with the requirements of the American National Standards Institute (ANSI). ANSI/CRRC S100 (2016) contains standard test methods for determining radiative properties of roofing materials. Many thanks to the CRRC Consensus Body, whose efforts ensured that all aspects of the standard were considered in this public review process.

To learn more about ANSI/CRRC S100 or to view a copy of the finalized 2016 version of the standard, please visit the CRRC Standards Development webpage.

If you have any questions about ANSI/CRRC S100 or the ANSI process please contact Sarah Schneider (510-482-4420 x202).

CRRC Program

Random Testing and Verification Testing Update

Random Testing is the method by which the CRRC ensures the credibility and accuracy of its Product Rating Program. Each year, the CRRC randomly selects and tests a percentage of rated products to verify that the solar reflectance and thermal emittance values are comparable to the values listed on the CRRC Rated Products Directory. Products that do not pass Random Testing are removed from the Directory.

Similar to Random Testing, Verification Testing is conducted for products that are certified as ENERGY STAR® roofing products through the Evaluation Services-CRRC (ES-CRRC®) program. The Verification Testing guidelines are determined by the U.S. Environmental Protection Agency and are similar to the CRRC’s Random Testing policy and procedures. As with Random Testing, products that are unavailable for procurement during the testing program year enter a rating removal/decertification process.

  

Earlier this year, 110 products were selected for Random Testing and 85 products were selected for Verification Testing. Products can be selected for Random Testing and Verification Testing in the same year. The CRRC has finished requesting procurement information for all Random Testing and Verification Testing products. The CRRC will continue testing until the end of the calendar year.

The CRRC regularly consults the Random Testing Working Group. This year, the CRRC began procuring nine specimens of tile products and started evaluating color family products on their initial test values instead of their default. The CRRC strives to make Licensed Sellers expectations as clear as possible this includes updating procedure language around Licensed Sellers expectation to pay for 3rd tests. 

If you have questions about the Random Testing and/or Verification Testing programs, please contact Hewson Shepherd (510-482-4420 x272).

ES-CRRC Program

ES-CRRC® Renewals

The ES-CRRC® program is for certification of ENERGY STAR qualified roofing products, and is a separate program from the CRRC Product Rating Program.
Invoices for the 2015 ES-CRRC® Program Renewals were due by April 30, 2016. Products may now face suspension for failure to pay Renewals fees. The late fee schedule is as follows:

If you have questions about the ES-CRRC® process, please contact Melissa Rissman (510-482-4420 x236).

ENERGY STAR® Version 3.0 Specification

On December 20, 2013, the U.S. Environmental Protection Agency released the final draft of the ENERGY STAR Version 3.0 Roof Products Specification and Test Method. Version 3.0 requires all aged measurements to be taken from products that have been weathered at a test farm; aged values from existing roofs will no longer be accepted. Version 3.0 will affect all products that are not weathered at test farms in three different climate zones (i.e. aged testing).

All ENERGY STAR certified roofing products must be certified to Version 3.0 by July 1, 2017. After July 1, 2017, all existing ENERGY STAR certified roofing products that have not been certified to Version 3.0 will lose certification and be removed from the ENERGY STAR Qualified Products List.

The CRRC has been certifying new products and recertifying existing products to Version 3.0 since June 2014. To recertify your products to Version 3.0, please:

  • Complete a Data Submission Form, and email it to Melissa Rissman
  • Submit the Recertification Fee ($100.) Renewal fees in the subsequent year will be waived for recertified products.

Detailed information can be found on the ES-CRRC webpage. Please contact Melissa Rissman (510-482-4420 x236) with questions.

ENERGY STAR® Verification Testing Update

As an ENERGY STAR Certification Body, the CRRC is required by the U.S. Environmental Protection Agency to administer verification testing of ENERGY STAR certified roofing products. For an update on the 2016 verification testing cycle, see the above Random Testing and Verification Testing Update.

ISO 17065 Accreditation Renewal

CRRC’s accreditation to the International Standard (ISO) 17065 was renewed in January 2016. Accreditation to the International Standard is required for all ENERGY STAR Certification Bodies.

If you have any questions about CRRC’s accreditation to ISO 17065 please contact Sarah Schneider (phone: 510-482-4420 x202).

New Research Clearly Shows Insulation and Reflectivity Go Hand-in-Hand


Kurt Shickman
Executive Director, Global Cool Cities Alliance


A new field study and model analysis of black and white roof membranes over various levels of insulation by Princeton University and Princeton Plasma Physics Lab highlights the interconnected role of reflectivity and insulation in roofing systems. Their study, published in two parts in Energy and Buildings, found clear evidence that reflectivity is the driving variable for minimizing heat flux during the summer, and that insulation levels are the driving variable during winter.1,2 The study is the latest to conclude that, while the concept of the “winter heating penalty” for reflective roofs exists, its negative effects on heat flux and energy consumption have been substantially exaggerated in comparison with roofs with lower reflectivity. 
 


The researchers deployed high-resolution heat flux sensors over and through various roofs in a building complex located inside the Princeton University campus (approximately 50 miles west of New York City and 45 miles east of Philadelphia). They then gathered data over the course of one year. The buildings were very similar, with the exception of different colored roof membranes (black or white) and varying thicknesses of polymer-based insulation (R21 up to R48). This study is one of the first to directly observe heat fluxes entering and leaving the building with sensors embedded inside the roof structure and is the first to simultaneously use a high accuracy and resolution model to address the same issue.

The findings are easiest to observe on the two buildings with R24 insulation levels but different membrane colors. The roofs were installed at the same time (spring 2012) on buildings in close proximity to one another. During the cold months (November - April), both the white and black roofs let the same amount of heat escape from the building, and thus, require heating. In the summer months, however, the heat gained by the white roof is minimal and much smaller than the heat gained by the black roof. In this observation, the white roof displays a stronger ability to reject and shed heat in the summer, and no difference in performance during the winter in comparison to the black roof.

There is ongoing debate on the energy benefits of deploying cool roofs in the Northeastern United States, where winters are cold and summers are hot. The arguments are often based on the notion that, if reflectivity cools off the roof in the summer, it must also do the same in winter. This new research joins a body of scientific inquiry that shows that roofs are more complex than that false bit of common sense.  Reflectivity is a net energy benefit to buildings in cool to cold climates and should be paired with insulation to be a truly high-performance roof system.

Technical Committee Meeting Recap

Technical Committee Meeting Updates

Proposed ASTM Directionally Reflective Materials (DRM) Test Method
At its March 8, 2016 meeting in Orlando, Florida, the Technical Committee made a recommendation to the Board of Directors for the CRRC to submit a proposal to ASTM for the DRM test method to be included as an annex or appendix to ASTM C1549. The CRRC DRM working group was tasked with coordinating the proposal. A proposal was submitted to the ASTM C16 Committee ballot for development of a standalone test method for directionally reflective roofing products.
 
Rapid Ratings Variegated Shingle Procedure
The Technical Committee approved the procedure for preparing and measuring the radiative properties of variegated shingle specimens for the CRRC Rapid Ratings Program. The procedure was developed by shingle manufacturers with the support of the CRRC Methods & Instruments subcommittee. The Board of Directors officially adopted the procedure on March 9, 2016.
 
The next Technical Committee meeting will be a conference call on August 18, 2016. If you would like to participate and/or be added to the Technical Committee email distribution list please contact Sarah Schneider (510-482-4420 x202).

Working Group Updates

Random Testing Working Group
This group is tasked with providing guidance on the random testing and verification testing activities, policies, and procedures. The working group is currently focused on defining clearer Licensed Seller expectations, investigating the testing limitations of variegated and blended tile products, and evaluating random testing of Color Family and Compound Products.

Rough Substrates for Field-Applied Coatings
The round robin study evaluating a defined “rough substrate” for use with field-applied coatings was completed in May 2016. The results of the study are being reviewed by the working group, and will be presented to the Technical Committee at a future meeting.

E1918 Precision and Bias Statement
The ballot under ASTM subcommittee D08.18 was circulated to subcommittee members in May 2016. The ballot would add a precision and bias section to ASTM E1918, based on the interlaboratory study (ILS) that was conducted in 2012 by CRRC and Lawrence Berkeley National Laboratory. An additional ILS is planned to test granule-surfaced products that were not included in the first ILS. The second ILS is being led by Jean-François Côté of Suprema.

Methods & Instruments Subcommittee
This subcommittee is tasked with evaluating new test methods and instruments for their viability and relevance to the CRRC Product Rating Program. The subcommittee is currently evaluating whether ASTM C1549 should be expanded to include a new portable reflectometer instrument.

If you are interested in the Random Testing working group, please contact Hewson Shepherd (510-482-4420 x272). For interest in other working groups, please contact Vanessa Morelan (510-482-4420 x224).
