Chairman's Corner

Hello all, and welcome to this edition of the CRRC Newsletter. We hope you find it informative! There has been no shortage of activity at the CRRC. Here are a few examples of the accomplishments since the last newsletter:

- Much work has been completed to include the Accelerated Aging Test Procedure and the Directionally Reflective Test Procedure into the CRRC program. This work continues and is nearing completion. Stay tuned for more details about accelerated aged ratings in the spring.

- Revision of the CRRC-1 ANSI Standard has begun under the leadership of Jonathan Humble, Sarah Schneider  and Alexis Wong, thank you all for your hard work!

- An updated policy has been developed and implemented for the Random Testing Program to facilitate timely completion of this extremely important element of the product-rating program. Arshak Zakarian led the effort with a lot of great input from the Random Testing Working Group. Thank you to everyone who has been involved!

- A contract has been signed with Energy Solutions to continue the management of the Cool Roof Rating Council through 2015. The Board would like to thank Jeffrey Steuben and the entire CRRC staff for their dedication in supporting the technical, educational, and financial management goals of the organization.
In 2015 we will continue work on the completion of the strategic plan that will help guide the direction of the organization in the future.

We look forward to membership participation as this plan is developed at the Membership Meeting in Las Vegas on June 18th and throughout the year.

Thanks again for all of your support in 2014 and we look forward to your continued involvement in 2015!

Cool Roofs in the News

Efficacy of Cool Roofs Confirmed in Regions of China

With support from the U.S.-China Clean Energy Research Center Building Energy Efficiency (CER-BEE) Consortium, a team of Berkeley Lab and Chinese researchers have conducted the first comprehensive cool roof study in China.

The study simulated and evaluated energy use throughout the year in five climate zones in China and concluded that cool roofs would be effective at reducing greenhouse gases and air conditioning demand in climates with hot summers.
Chinese climate zones

Energy savings were similar to in the United Sates; however, benefits of these savings may have even larger overall impacts since China emits higher rates of pollution from energy produced from burning coal.

Photonic Radiative Cooling Material Developed by Stanford Engineers

A team of Stanford engineers has developed a highly reflective coating material to help cool buildings through photonic radiative cooling, a process involving both reflecting sunlight as well as offloading heat from inside buildings.

This incredibly thin, multilayered material reflects up to 97% of sunlight and effectively radiates heat at a frequency that does not warm the air.

Currently, the prototype panel is the size of a personal pizza, but the research team aims to design the material for large-scale use on roofs as an affordable technique to reduce air conditioning demand.

The proposed revisions and comments received during the first Public Comment Period (May 29 to July 29, 2014) have been reviewed by the ANSI/CRRC-1 Consensus Body and a second Public Comment Period will commence in early 2015 (TBD). To learn more about the ANSI/CRRC-1 Standard and the revision process, please visit the CRRC Standards Development webpage.

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

CRRC Program

Random Testing and Verification Testing Update

Changes to CRRC’s Procedure #1 – Random Testing Program Policies and Processes were approved by the Board of Directors in November 2014. The changes establish new guidelines for CRRC staff and Licensed Sellers in order to help ensure fairness in the Random Testing program for all participants each year.
Random Testing is an important 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 all active Licensed Seller products in order to verify that tested solar reflectance and thermal emittance values match listed values on the CRRC Rated Products Directory. Products that do not pass the Random Testing program are removed from the Rated Products Directory.

Products found unable for procurement during the testing program year enter a rating removal/decertification process.  Successfully completing the program’s annual random testing assignments improves accuracy and reliability of the Rated Products Directory. These changes took effect beginning January 1, 2015, and will apply to all future and previous Random Testing program years.

Verification Testing is conducted for ENERGY STAR certified products through the Evaluation Services-CRRC (ES-CRRC) program as administered by the CRRC. The Verification Testing program guidelines are determined by the Environmental Protection Agency (EPA) and are similar to the newly adopted Random Testing Policies. As with the Random Testing program, products determined unable for procurement during the testing program year enter a rating removal/decertification process.

The CRRC is wrapping up the 2014 Random Testing and Verification Testing programs. Please see the table below for an update on 2014 and previous program years. With the Procedure #1 updates, the CRRC expects the new policies to contribute to a swift completion of previous and future program years. Please contact Arshak Zakarian, Random Testing Coordinator, at with any questions about the Random Testing and Verification testing programs.

Lawrence Berkeley National Laboratory

CRRC Approves Laboratory Aging Practice for Interim Product Rating
By Ronnen Levinson,
Berkeley Lawrence National Laboratory

Cool roofs can decrease the energy required for cooling buildings and help mitigate the urban heat island effect by reflecting sunlight away from buildings and cities. However, the solar reflectance of a roof is often reduced by aging, which includes soiling (deposition of particles and the growth of microorganisms) and weathering (exposure to water, sunlight radiation and temperature swings). 

In collaboration with over 50 industrial partners, Concordia University, and the Cool Roof Rating Council (CRRC), Lawrence Berkeley National Laboratory (LBNL) has developed a laboratory protocol that reproduces the solar reflectance of roofing products naturally aged for three years in only a few days.

The method uses a calibrated aqueous soiling mixture containing dust minerals (clays and iron oxide), soot (black carbon), organic matter (humic acid), and salts that is sprayed onto specimens of roofing materials. The specimens are also exposed to ultraviolet radiation, heat, and moisture before and after soiling. The method requires only a commercial weathering device (Figure 1), a simple soiling apparatus (Figure 2), and the appropriate use of each soiling component (Figure 3). 
Figure 1. Commercial weathering device. 
Figure 2. Soiling apparatus.
Figure 3. Components of the soiling mixture left to right: salts, clays + iron oxide, humic acid, and soot.

Different soiling mixtures were optimized to reproduce spectral reflectance features of roofing products aged at the three exposure sites used by the CRRC—Miami, Florida, which is hot and humid; Phoenix, Arizona, which is hot and dry; and Cleveland, Ohio, which is temperate but can have high concentrations of airborne pollutants. A fourth soiling mixture was devised to replicate the aged solar reflectance averaged over all three sites, which is the aged value reported by the CRRC on rated product labels.

The accelerated aging method was applied to 25 products, including single-ply membrane, field-applied coating, metal, tile, modified bitumen, and asphalt shingle. Consistency was observed between the three-year-aged solar reflectance reported in the CRRC’s Rated Products Directory, and the three-site-average value obtained using the accelerated aging method (Sleiman et al. 2014, Solar Energy Materials & Solar Cells, volume 122, pages 271-281). The laboratory method was also successful in replicating three-year-aged thermal emittance. A recently concluded interlaboratory study with nine participants demonstrated that laboratory-aged values of solar reflectance and thermal emittance are consistent within and between laboratories.

Following review of the method by its Technical Committee and Board of Directors, in June 2014 the CRRC approved the use of the method, formally known as the ‘Laboratory Aging Practice,’ to provide an optional way for manufacturers to obtain simulated aged ratings before the end of the three-year weathering process. It is important to note that the laboratory aged values are only interim values, and that all products must still go through the three-year aging process at weathering farms to be eligible for a CRRC rating. Once the three-year aging process is complete, the interim values will be replaced by the three-year aged values.

The solar reflectance and thermal emittance measured after laboratory exposure will be reported as ‘laboratory-aged’ values in the CRRC’s Rated Products Directory. Because California’s 2013 Title 24 Building Energy Efficiency Standards accept both laboratory-aged and three-year aged product ratings, the laboratory aging option will help manufacturers introduce new products to market while undergoing the three-year aging process. The Laboratory Aging Practice can also be used informally by manufacturers during product development.

Laboratory aging for CRRC product rating will only be performed by CRRC approved laboratories that meet the requirements established by the CRRC Product Rating Program. These requirements include attending a CRRC laboratory-aging training in 2015 and incorporating the Protocol into the laboratory’s ISO 17025 Scope of Accreditation. Measurements of solar reflectance and thermal emittance for CRRC product rating will continue to be performed by CRRC Accredited Independent Test Laboratories.

The Laboratory Aging Protocol is also being developed as a standard practice by ASTM (American Society for Testing and Materials) Committee D08 on Roofing and Waterproofing.

Working Group Updates

Rough Substrates for Field-Applied Coatings
This working group has developed a draft test procedure, in partnership with the Reflective Roof Coatings Institute, Roof Coatings Manufacturers Association and 3M, for the creation of a defined “rough substrate” that will be required for testing all field-applied coatings.

The group is coordinating a round robin study to determine the repeatability and reproducibility of ratings developed using this process.

Development of NIST Traceable Standard
This working group is evaluating the potential development of a National Institute of Standards and Technology (NIST) traceable standard for measuring thermal emittance. The group is determining the scope of the study and is garnering support from interested parties. A sub-task group is evaluating the technical aspects related to the development of the standard.

ASTM E408 Consideration
This working group is evaluating the use of ASTM E408 as an alternate method of measuring thermal emittance because it may prove advantageous for measuring certain types of materials. The CRRC had helped coordinate the update of the ASTM E408 test method, approved in 2013. The working group is coordinating a round robin study for 2015.

Method Evaluation Working Group
This working group is evaluating the differences between ASTM C1371 and the Slide Method results to develop a methodology for determining if re-testing of products under a more accurate test method is needed.

Methods & Instruments Subcommittee
This newly-created working group is tasked with evaluating new test methods and instruments for their viability and relevance to the CRRC Product Rating Program.

If you are interested in joining a working group, please contact Sarah Schneider at or (510) 482-4420 x202.
