Thank you to everyone who submitted their 2010 renewals payments! Companies that did not submit their 2010 renewals payment by May 1st have been terminated as members and/or licensees. This includes termination of all active products listed under those companies. Companies that did not submit payments for 2010 have already been notified by email, phone, and mail. If a terminated company wishes to reactivate their membership, licensee status and/or rated products, please contact Alexis Wong at email@example.com or (510) 482-4420 x279.
The CRRC has increased the frequency of Test Farm product placement from a quarterly basis to every other month. Test farms have already begun to implement this policy. We hope this change in policy will assist you in submitting new CRRC rated products. Please find below the official language to be added to the CRRC-1 Program Manual:
When shipping test samples between CRRC Accredited Independent Test Laboratories (AITLs) and Test Farms, the CRRC recommends that the shipper send the samples with a tracking number and include a listing of the shipped samples so that the recipient can check the shipment for completeness. The CRRC recommends that the recipient acknowledge receipt of the samples to the shipper. The CRRC, however, assumes no responsibility for the shipment or receipt of samples, including the manner thereof, and the CRRC shall have no liability for lost or damaged samples.
The Board has approved the use of a CRRC Rated Product Logo to be used by licensees with rated products in good standing. Licensees who would like to use the Rated Product Logo must submit a signed Rated Product Logo License Agreement (electronic form is acceptable). Please also review the How Do I Use the CRRC Logo document regarding the guidelines for using the Rated Product Logo. Once the CRRC receives a signed copy of the Rated Product Logo License Agreement, we will send you useable images of the Rated Product Logo.
Please note the following regarding applying the Rated Product Logo to your promotional materials:
If you have specific questions about logo use, please contact Alexis Wong at firstname.lastname@example.org or (510) 482-4420 x279.
For your convenience and in order to reduce paperwork, the CRRC is now accepting electronic copies of all applications and agreements. This includes scanned copies of all forms or electronic forms with digital signatures. The CRRC will still be accepting forms by mail as well. All documents are available on our website here. If you would like to submit an electronic form, you can email Melissa Rissman, our Applications Liaison, at email@example.com or fax the form to (510) 421-0241.
A new line has been added to the Initial Product Rating Application (CRRC F-3). To assist with identifying products, you may now enter a Manufacturer SKU number or other identifying internal number. If no SKU or identifying number is available, simply leave the field blank. The newly-modified Initial Product Rating Application (CRRC F-3) can be found on the website here. here
The CRRC adopted the Interim Tile Test Method in winter of 2008, with an initial expiration date of June 1, 2010. The intent was that by June 2010 the CRRC would have adopted a permanent test method for tile and other profiled products. Due to complications with the E1918A Round Robin, and delays in receiving external funding to support test method research, the CRRC will not be ready to adopt a permanent tile test method by June 2010. In recognition of this fact, the Board has voted to extend the expiration date for the interim method to December 31, 2010.
Random testing is the method by which the CRRC ensures the credibility and accuracy of our rating program. Each year, we test 10% of all active rated products in order to guarantee that their reflectance and emittance numbers match their listed values. We are in the process of wrapping up our 2009 random testing results and wanted to share the results.
Once we have finished 2009 random testing, we will mail a result letter to all licensees who had products tested. SFinal results will be presented at the June membership meeting. The 2010 random testing process has commenced and 93 products have been selected for verification. If you have any questions about random testing, please contact Alexis Wong at firstname.lastname@example.org or (510) 482-4420 x279.
The CRRC has kicked off our international outreach efforts! Sherry Hao, CRRC’s Administrative Manager, presented at the China International Energy Efficiency & Zero Energy Building Envelope Conference held from March 31st to April 1st in Beijing. The conference was sponsored by the U.S. DOE and China Architecture Design and Research Group and included presentations from the Chinese Ministry of Housing and Urban-Rural Development, Environment Canada, National Fenestration Rating Council, and representatives for energy efficiency efforts in Japan and India. The CRRC presented on the energy savings and environmental benefits of cool roofing, the technology behind cool roofing, as well as an overview of the CRRC Product Rating Program. Under this initiative, the CRRC will collaborate with the DOE in its efforts to develop international cool roof rating infrastructures to support building code implementation. Future outreach efforts will focus on the countries of India, China, Australia and Thailand. Any CRRC licensees interested in participating in international conferences should please contact email@example.com.
The CRRC is contracting with Lawrence Berkeley National Laboratory (LBNL) to hold a CRRC Lab Training workshop at their site in Berkeley, California. The one-day course provides training on measuring the optical properties of roofing materials both in the laboratory environment and in the field.
The Technical Committee held a phone meeting on March 17th, 2010. The following topics were discussed:
The next Technical Committee Meeting is scheduled for June 9, 2010 in Miami, FL. If you would like to attend this meeting, please register here.
The CRRC has collected the final ballot from the Consensus Body, voting to approve the CRRC-1 standard with the revisions made during the ANSI standards process. The ANSI revised standard will be presented to the Board at the May 20, 2010 Board meeting. Should the Board vote to approve the ANSI standard, the CRRC will publish the accepted ANSI CRRC-1 Standard document to the public on the CRRC website. Informative documents are available for review here.
The Board has approved the addition of Solar Reflectance Index (SRI) to the Rated Products Directory. SRI is a single value calculated from the solar reflectance and thermal emittance values of a material. Many cool roof codes and programs reference minimum reflectance and emittance values as well as alternative minimum SRI values, including: LEED, California’s Building Energy Efficiency Standards (Title 24), and ASHRAE 189.1, 90.1 and 90.2. SRI will be calculated using Lawrence Berkeley National Laboratory’s calculator, available here. Both initial and 3-year aged SRI values will be included in the Rated Products Directory starting this summer.
Recently, the CRRC has been approached by several manufacturers of clear surface coatings that are intended to improve the solar reflectance of roofing materials. These coatings work in a variety of ways, including nano-scale reflectance technology, soiling reduction, and increased mirror-like reflectance at low incidence angles. Manufacturers of these coatings are interested in working with the CRRC to test their products and verify performance. As the number of clear cool roof coatings increases, consumers, code bodies, and rebate programs will need ways to evaluate their effectiveness. The CRRC is the logical entity to provide that information, and will need to develop the procedures to do so effectively.
Ratings, Codes and Programs
As part of the update to the 2011 Title 24 Residential Building Standards, Architectural Energy Corporation is evaluating the cost effectiveness of more stringent requirements for residential cool roofs and roof insulation. AEC is conducting a survey designed to determine incremental costs of highly reflective roofing products, and the availability of cool roof products on the market for different roof types (shingle, tile, metal roofing). If CRRC Licensees are interested in participating in the AEC survey please click here to access the survey. The survey takes 10 to 15 minutes to complete. Any feedback that roofing product manufacturers can provide will be valuable to the codes and standards process and much appreciated.
The EPA ENERGY STAR program is currently considering enhanced testing and verification requirements that will cover all ENERGY STAR programs, including the Roofing Products program. This effort to implement verification infrastructure to the ENERGY STAR program came about from a congressional report by the U.S. Government Accountability Office that highlighted several instances where approved ENERGY STAR products failed to meet program requirements. The report can be viewed here.
On March 30th Tampa Electric filed for approval from the Florida Public Service Commission to implement a new lineup of energy efficiency programs, including a rebate of up to $.60 per square foot for the installation of a cool roof system. The full article can be viewed here.
Membership and Outreach
On February 25, 2010 the Board held an in-person meeting in New Orleans, LA, in conjunction with the International Roofing Expo Conference. The agenda was packed with discussion items, resulting in the following key decisions:
Compound Rating Application
On April 22, 2010 the Board held a conference call meeting. As too many topics were on the table for the Board to address in this 2 hour meeting, the Board added a conference call meeting on May 20. The following decisions were made at the April Board meeting:
The CRRC Board of Directors has four positions opening up this year, two Class A member positions and two Class B member positions. Board member candidates have been nominated by the CRRC membership and voting will commence on May 5th and end on June 4, 2010. Election results will be announced to all CRRC members by June 14th. The newly elected Board of Directors will convene and vote on officer positions at the June 23rd Board meeting. If you have any questions about the CRRC Election process, please contact Karl@coolroofs.org.

|•||Performance history of the roof membrane in the climate of the project. The durability of all cool roof coverings is not equal and some non-cool roof coverings provide a service life far exceeding less durable cool roofs. The high cost of roof replacement for a less durable cool roof will likely more than offset potential energy savings. Designers should consider long term performance history and durability when selecting a roof cover type.
|•||Energy Savings of Proposed Cool Roof System. The potential for energy savings of cool roofs vs. black roofs is based on the reduction of the roof surface temperatures and subsequent decreased energy use during cooling periods. Energy savings, however, decrease with increasing thermal resistance of the roof assembly and are less in northern climates and regions with lower costs of energy. If energy saving is the primary goal, vegetated roofs and some ballasted roof membranes also provide comparable energy savings. Although ballasted roofs may provide comparable energy savings compared to a cool roof, they do not reduce the heat island effect.
|•||Moisture Migration Within The Roof Assembly. The potential for moisture migration and accumulation within the roof assembly should be analyzed. Moisture from other construction components, construction generated activities and interior occupancy may condense within the roof assembly and result in premature failure of the roof cover. Cool roofs, as non-cool roofs, require the proper design of the entire roof assembly to perform properly.
|•||Long term (or aged) reflectance properties of the cool roof covering. The type of roof covering, the roof slope and the environment of the project may all affect the reflective performance of the cool roof covering over time. The loss of reflectance and maintenance costs for cleaning should be considered when analyzing potential energy savings of cool roof coverings.
|•||Local & Regional Building Code Requirements for Cool Roofing. The designer should review local and regional code requirements for cool roofing when selecting a cool low slope roofing type as the definitions of a cool roof and required testing vary.

Word is spreading about the cool roofing! From national news to local news, from commercial websites to blogs, more people are learning about the CRRC and the benefits of cool roofs. Here are just some of the many examples of news coverage that cool roofing materials are receiving:
Hot New Concept for Cool Roofs
Scientists at United Environment & Energy LLC in Horseheads, N.Y. have developed a roof coating made of waste cooking oil from restaurants that detects temperature changes and automatically switches roles, reflecting or transmitting solar heat, when the outdoor temperature crosses a preset point that can be tuned to the local climate. The coating was presented March 21st at the 239th national meeting of the American Chemical Society in San Francisco. Researchers expect it could be available to consumers in three years. You can find more information about this new technology at Science News and Sify News.
Coolest Block in Philadelphia
The Energy Coordinating Agency of Philadelphia is partnering with Dow Chemical Company Foundation to kick off a contest where row home owners can enter to win an energy-saving cool roof, and air sealing and insulation upgrades for their entire block. In the “Coolest Block” contest entrants will be judged on a range of criteria, but blocks with the highest resident participation have the best chance of winning. The full article can be viewed here.
Cool Roofing for Data Centers
Peer 1, a Vancouver based infrastructure service provider, is building its 41,000 square foot flagship data center in Toronto with a cool roof and high efficiency chillers. Data centers have enormous cooling needs during all seasons in most climates, eliminating the heating penalty that many other residential and commercial buildings experience in the winter months. The costs of cooling these data centers are significant and are leading companies across the globe to consider methods to curb these costs (including cool roofing technology). The percentage of new data centers incorporating cool roofs may dramatically rise over the next couple years. For more information see Peer 1 or Data Centers.
Art Rosenfeld makes a compelling case for cool roofs in the April 17th Issue of the Wall Street Journal when he claims:
“Suppose over a period of 15 years, all eligible flat roofs in major cities from Chicago to Sydney were colored white, whether or not they are air-conditioned. That would offset the heating effect of 15 billion tons of CO2. It’s like turning off the entire world’s emissions for four months or about 40% of the world’s passenger cars for 15 years. This idea slows global warming, saves utility bills, and makes buildings and cities more comfortable in summer. I commend it to your attention.”
