Codes & Standards Update
The CRRC has submitted proposals to the following code bodies to update the reference to the CRRC’s American National Standard, ANSI/CRRC S100 (formerly CRRC-1 Standard) for the following codes:
- ASHRAE 90.1 – Energy Standard for Buildings Except Low-Rise Residential Buildings (I-P Edition). Proposal to update references to the CRRC ANSI standard. Changes proposed for the 2019 edition of 90.1.
- ASHRAE 90.2 – Energy-Efficient Design of Low-Rise Residential Buildings. Proposal to update references to the CRRC ANSI standard and to replace existing references to ASTM C1549 and C1371 with ANSI/CRRC S100 since those ASTM standards are referenced in ANSI/CRRC S100.
- ASHRAE 189.1 – Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings. Proposal to update references to the CRRC ANSI standard. Changes proposed for the 2018 edition of 189.1.
- International Energy Conservation Code (IECC) – Proposal to update references to the CRRC ANSI standard. Changes proposed for the 2018 edition of IECC.
- RESNET 301 – Standard for the Calculation and Labeling of the Energy Performance of Low-Rise Residential Buildings using the HERS Index. Proposal to update references to the CRRC ANSI standard and to replace existing references to ASTM C1549 and C1371 with ANSI/CRRC S100 since those ASTM standards are referenced in ANSI/CRRC S100.
The CRRC has also submitted proposals to the ASTM C16 subcommittee to adopt a new ASTM test method for measuring the solar reflectance of Directionally Reflective Materials and to update ASTM C1549 to remove the sole source footnote as part of the effort to make the standard device-neutral. The objective is to eventually expand the scope of the standard to enable various reflectometer instruments to be used in accordance with C1549 (the standard is currently written for Devices & Services’ Solar Spectrum Reflectometer, version 5). The proposed changes were vetted by the CRRC Technical Committee and Board of Directors.
For questions regarding CRRC’s codes and standards proposals please contact Sarah Schneider or (510-482-4420 x202).

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 products on the CRRC Rated Products Directory to verify that the solar reflectance and thermal emittance values are comparable to the values listed on the CRRC Rated Products Directory. If the randomly tested results are within +/-0.05 of the initial test values, then the product passes and remains on the CRRC Rated Products Directory. If the product does not pass the first test, then the product is given two more tests to pass, otherwise it is removed from the CRRC Rated Products Directory. CRRC annual renewal fees cover the costs of Random Testing for CRRC-rated products for the first and second test but not the third test. The CRRC will check with the Licensee before proceeding with the third test, at which point the Licensee can choose to either pay for the third test, terminate the product, or re-rate the product.
Similar to Random Testing, Verification Testing is conducted on products that are certified as ENERGY STAR® roofing products through the CRRC’s 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 (Appendix 5 of the CRRC-1 Program Manual). The passing criteria for Verification Testing is any solar reflectance value above 0.65 for low slope or low slope/steep slope products, and anything above 0.25 for steep slope products. ENERGY STAR Partners whose products are selected only for Verification Testing are invoiced for all fees related to product procurement, processing, and testing. ENERGY STAR Partners whose individual products are selected for both Random Testing and Verification Testing in the same year are not invoiced for Verification Testing.
Thank you to all Licensees and ENERGY STAR Partners for your participation and cooperation in the 2016 Random Testing and Verification Testing programs. The first round of testing is 100% completed, with only a handful of Random Testing products that still need to go through second or third tests in 2017. An update will be given at the Annual Membership Meeting on June 14, 2017.
Please check your mailbox to see if you have any products that were selected for 2017 testing. Notifications of product selection went out in early January, and procurement information is due two weeks later.
If you have questions about the Random Testing and/or Verification Testing programs, please contact Hewson Shepherd or (510-482-4420 x272).

ENERGY STAR® Specification Version 3.0
All ENERGY STAR certified roofing products need to be recertified to Version 3.0 before July 1, 2017 to remain on the ENERGY STAR Certified Products List. If your products have already been aged in accordance with ANSI/CRRC S100 – 2012 (formerly CRRC-1 Standard), there is no need to retest. But the products do need to be recertified.
The ES-CRRC Program is currently certifying products to Version 3.0 to ensure that products complete recertification by July 1, 2017.
Until your ENERGY STAR certified products are recertified to Version 3.0, they will remain certified under Version 2.2 or 2.3. After July 1, 2017, all certified products that have not been recertified to Version 3.0 will be removed from the ENERGY STAR Certified Products List.
To recertify your products to Version 3.0, please:
- Complete a Data Submission Form, and email it to melissa@coolroofs.org.
- Submit a recertification fee of $100 per product. If ES-CRRC renewal fees have been paid for the current year, renewal fees for the first subsequent year will be waived for recertified products.
Detailed information can be found on the ES-CRRC Program ENERGY STAR webpage. For questions, please contact Melissa Rissman or (510-482-4420 x236).

We’re Not in Kansas Anymore: Fluorescent Ruby Red Roofs Stay as Cool as White
Julie Chao, Science Writer
Lawrence Berkeley National Laboratory
Adapted by the CRRC
Elementary school science teaches us that in the sun, dark colors get hot while white stays cool. Now new research from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has found an exception: that certain dark pigments can stay just as cool as white by using fluorescence, the re-emission of absorbed light.
The results of the research, led by Berkeley Lab Scientist Paul Berdahl, were published recently in the journal Solar Energy Materials & Solar Cells, in an article titled “Fluorescent cooling of objects exposed to sunlight—The ruby example.”
Substantial research over the years from Berkeley Lab’s Heat Island Group has found that reflective roofs and walls can cool buildings and cars. This reduces the need for air conditioning and mitigates the urban heat island effect. By reflecting the sun’s rays back to space, these cool materials also release less heat into the atmosphere, thus cooling the planet and offsetting the warming effects of substantial amounts of greenhouse gas emissions. However, wider adoption of cool roofs has been hindered by aesthetic considerations. “We’ve heard many times (from roofing materials manufacturers), ‘We can’t sell white or pastel roofs; our customers want dark green, dark brown, and so on,’” Berdahl said.
Over the past 15 years, Heat Island Group researchers have used special pigments that strongly reflect invisible “near-infrared” light to make dark surfaces that stay cooler in the sun than conventional dark surfaces, though still not as cool as white surfaces. This new work shows that fluorescent cooling can boost the performance of these pigments by re-emitting at longer wavelengths some of the visible light that the surface must absorb to appear dark.
Using fluorescence, or photoluminescence, for cool materials is a new concept, and Berdahl, who is a physicist by training, has a patent pending on the technology. “People understand that materials that fluoresce are emitting energy,” he said. “What’s new here is the use of the fluorescence process to keep buildings cooler.”
When light hits a fluorescent material, the material actively emits energy in response, rather than passively reflecting the energy. Berdahl’s idea was to find a material that would absorb visible light and fluoresce (re-emit) mostly or entirely in the invisible near-infrared portion of the sun’s spectrum. “There have been thousands of fluorescent compounds identified,” he said. “Ruby’s properties are well known and well studied, and I realized it’s a material that could work.”
His first experiment was to use an array of synthetic ruby crystals, which he purchased online and said were surprisingly inexpensive. Attached to a bright white coating and exposed to bright sunlight, the dark-red ruby-covered coating stayed cooler than an off-white surface.

Berdahl and Berkeley Lab research associate Sharon Chen then synthesized ruby powder, or aluminum oxide, doped with varying amounts of chromium to create different shades of red pigment. They prepared ruby paint from the powders, and applied these paints over bright white substrates. When exposed to sunlight, the ruby paint samples stayed as cool as white materials.
“The ruby powder does need more work to make it as deep red as the ruby crystal,” Berdahl said.
If the product were to be commercialized, Berdahl said that the cost is not expected to be substantial and its durability is expected to be similar to other coatings. “Rubies have a reputation for being expensive, but they’re mostly aluminum oxide, which sells for about 70 cents per kilogram (or about 30 cents per pound),” he said.
PPG Industries, a Pittsburgh, Pennsylvania-based coating manufacturer also involved in the research, is conducting weathering tests with prototype fluorescent coatings.
In follow-up work Berdahl has identified blue materials that also fluoresce and showed that they can be combined with other colors to yield green and even black materials that stay cool.

Working Group Updates
Random Testing Working Group
This Board-level working group is tasked with providing guidance on Random Testing and Verification Testing activities, policies, and procedures. The working group is currently focused on evaluating thermal emittance values, assessing aluminized coating products and tile product failure, and the Random Testing appeal process.
Rough Substrates for Field-Applied Coatings Working Group
The results from the rough substrates round robin were evaluated by the Technical Committee’s (Committee) Rough Substrates Working Group in August 2016. The working group confirmed the procedure as repeatable and reproducible, and presented a recommendation to the Methods and Instruments (M&I) Subcommittee to advance the dual rating for coatings study. The round robin results were then presented to the Committee in August, and a recommendation was made to the Board of Directors (Board) to adopt dual rating system for coatings. The Board approved the recommendation in September and directed the Committee to develop a specification to implement the method. The rough substrates working group and M&I Subcommittee are currently addressing additional questions regarding the aging process, and will present the specification to the Technical Committee for evaluation at a future meeting.
Methods & Instruments Subcommittee
Aggregate Faux Shingle Study: At its June 2016 meeting, the Board of Directors asked the Technical Committee to develop a proposal for studying the faux shingle test method for aggregate products. The study proposal is currently being developed by the M&I Subcommittee with input from aggregate manufacturers. The study proposal will be presented to the Technical Committee for evaluation at a future meeting.
Rough Substrates for Coatings Specification: The M&I Subcommittee provided preliminary feedback on the draft specification in September regarding the applicability of the Slide Method for coatings applied to rough substrates. CRRC staff worked with Devices & Services to measure thermal emittance using an adaptor to the emissometer device. The preliminary findings were presented to the M&I Subcommittee in December. The M&I Subcommittee will continue to evaluate the thermal emittance results to determine the applicable test method.
Potential Technical Research Topic Working Groups: CRRC staff are coordinating working groups to facilitate the development of scope and costs to present to the Board for each of the three top-ranked research projects: the impact of aging beyond three years; the comparison of data between ASTM E901, E1918, and C1549; and the comparison of test values for lab aged and three-year aged products.
If you are interested in joining a Technical Committee working group, please contact Vanessa Morelan or (510-482-4420 x224). For the Random Testing working group, please contact Hewson Shepherd or (510-482-4420 x272).
