May 23 Technical Committee Meeting Updates

Equipment Purchase for Lab Training
CRRC staff proposed the purchase of a handheld colorimetry measurement device for use at the CRRC’s annual lab training. Surface Optics offered to loan one for the training. The Technical Committee recommended that staff identify which device models are currently used by labs.
The colorimetry measurement device is used to test Hunter L,a,b values for the CRRC Color Family program.

CRRC Rounding Protocol
At the recommendation of a licensee, the Committee discussed the adoption of ASTM E29, a numeric rounding standard. Participants agreed to maintain the current “round half up” process and not adopt the proposed standard.

“Unusable” Product Program Manual Protocol
The Committee discussed adding Program Manual language to address situations where samples depreciate during aging due to reasons not classified as “uncharacteristic damage.” After revising the text, the Committee sent the language to the Board for approval.

Granule Product Aged Testing
The Committee discussed a CRRC Accredited Independent Testing Laboratory’s (AITL’s) request for clarification on how to conduct aged testing on a rough–surfaced aggregate sample. The Committee assigned the topic to the E408/Curved Tile Emissivity Working Group for further investigation. The Committee also reviewed a case involving aged granule products on different substrates, and determined that the metal-backed product rating could be used in lieu of the wood–backed product rating because both samples have the same surface formulation.

2011 Interlaboratory Comparison Results
The interlaboratory comparison study is run each year to ensure AITLs are in compliance with CRRC test procedures. CRRC staff presented the results of the 2011 study, which showed very low variability between sample measurements for solar reflectance and thermal emittance, but higher variability in the thickness measurements. The Committee requested that all labs calibrate their micrometers used to take thickness measurements.

AMTL Interlaboratory Comparison Proposal
The interlaboratory comparison study currently only includes AITLs. CRRC staff proposed integrating AMTLs (Accredited Manufacturing Testing Laboratories) into the annual study. Manufacturer labs would only be required to test the product type they work with (e.g. tile or factory-applied coatings). The Committee approved the proposal language and sent it to the Board for final approval.

Slide Method Optional Use
The Committee discussed allowing the option for metal–backed coating products to be tested for emittance using the Slide Method rather than ASTM C1371. The Committee will discuss this topic in more detail at the August 8, 2012 meeting.

Technical Working Group Updates

The Technical Working Groups include:

•   ASTM E1918 Precision & Bias
•   Electronic Gauges
•   CRRC–1 Test Method #1 Precision Statement
•   Solar PV & Cool Roofs:
•   ASTM E408
•   E408/Surface Optics Study
•   Curved Tile Emissivity
•   Method Evaluation

If you would like more information, or are interested in joining any of these working groups, please contact Jeff Steuben at jeff@coolroofs.org or (510)482-4420 x288.

ASTM E1918 Precision & Bias
The study commenced in early June with Lawrence Berkeley National Laboratory creating an instructional video to help other labs conduct the test method. A pair of pyranometers purchased by the CRRC will be sent to each participating lab in turn. Each lab has in possession a set of the study samples. The working group hopes to conclude the study by fall 2012.

Electronic Gauges
The round robin study of ASTM D7091, a standard for thickness measurement, concluded in June. The results will be presented at the August 8, 2012 Technical Committee meeting where the Committee will consider adopting the standard into the CRRC program.

CRRC–1 Test Method #1 Precision Statement The working group met in April to draft a study for developing the CRRC–1 Test Method #1 precision statement. The Technical Committee reviewed this study summary and provided feedback.

Solar PV and Cool Roof Working Group
The group met on July 12, 2012 and discussed opportunities for research projects. Ms. Amy Nagengast gave an overview of her research at Carnegie Mellon.

ASTM E408 Working Group
CRRC staff are working with device manufacturers AZ Technology and Surface Optics to update the standard to include the new measurement devices, as well as a conversion from direct normal to total hemispherical thermal emittance.

E408/Surface Optics Study
This study will provide thermal emittance values using E408 and a Surface Optics device for a variety of granule sizes, curved tiles, and shingle products. The resulting data will be presented to the Committee to consider possible default thermal emittance values to attribute to certain product types.

Curved Tile Emissivity Working Group
The working group is investigating options around applying a generic emittance value for products which cannot be readily measured through current CRRC test methods. The working group has been merged into the E408/Surface Optics study.

Method Evaluation Working Group
The working group was formed to review the technical aspects of potential product retesting for CRRC products due to a change in available test methods. The group is analyzing the threshold for significance to determine what would trigger retesting and which products would be affected.

Ratings, Codes and Programs

Title 24 Update

The 2013 California Title 24 Building Energy Efficiency Standard was approved on May 31, 2012. Over the next 30 years, the new standard is projected to save enough electricity to run 1.7 million homes. Title 24 2013 is scheduled to go into effect January 1, 2014 and features several changes to the cool roof requirement, including a new prescriptive insulation tradeoff.

Prescriptive Standard for Low–Slope Products
Title 24 Version Minimum 3-year Aged SR Minimum TE Minimum SRI
2008 (current) 0.55 0.75 64
2013* 0.63 0.75 75

To review a copy of the redlined CRRC–1 Standard or to submit comments, please go to CRRC Standards Development page, and select the link under the “Current Status” section.

If you have any questions about the ANSI process, please contact Alexis at alexis@coolroofs.org or (510) 482-4420 x279.

CRRC Program

Random Testing Update

Random testing is the method by which the CRRC ensures the credibility and accuracy of the rating program. Each year, the CRRC tests 10% of all active licensed seller products in order to guarantee that their tested reflectance and emittance values match their listed values. Products that do not pass random testing are removed from the Rated Products Directory.

The 2010 random testing program is in its final stages with the following product breakdown:

2010 Random Testing Status # of Products
Completed & Passed 80
Collection in Process 3
No Longer Sold 4
Awaiting Re-Testing* 4
Failed 3
TOTAL 92

The 2011 random testing program is well underway with 133 products, with the following breakdown:

2011 Random Testing Status # of Products
Completed & Passed 69
Collection in Process 26
Samples Awaiting Testing 15
No Longer Sold 19
Awaiting Re-Testing* 4
TOTAL 133

The 2012 random testing program began in April with the following product breakdown:

2012 Random Testing Status # of Products
Completed & Passed 6
Collection in Process 80
Samples Awaiting Testing 61
No Longer Sold 4
Awaiting Re-Testing* 3
TOTAL 154

*“Awaiting Re-Testing” includes products that have failed their first or second round of testing, out of a possible of three tests, and are thus not considered “failed” products. Failed products are removed from the CRRC Rated Products Directory.

Once each annual round of random testing is completed, the CRRC will mail results letters to all licensees who had products tested. If you have any questions regarding random testing, please contact Ethan Guy at ethan@coolroofs.org or (510) 482-4420 x237.

Product Rating Program Tips & Tricks

The CRRC Board of Directors and Technical Committee are constantly updating and improving the program, often through suggestions brought forth by licensees and AITLs. In February 2012, the Board approved improvements to the F–2 and F–13 test results report PDFs that include auto–rounding of reported values. The CRRC would like to remind labs and licensees to fill in all forms electronically in order to take advantage of new features such as auto–rounding, and to decrease errors due to handwriting interpretation.

If you have any questions or comments for improvements to the forms, please contact Jessica Clark at jessica@coolroofs.org or (510) 482-4420 x227.
