General Updates / Administrative
We are pleased to announce the addition of the Solar Reflectance Index (SRI) to our Rated Products Directory. Users can now reference this metric to gauge the energy performance of roofing products, in addition to posted solar reflectance and thermal emittance values.
In keeping with our mission to educate the public and maintain a relevant, cutting–edge rating system, the SRI is a valuable addition to the CRRC Rated Products Directory as it is referenced by LEED, ASHRAE 90.1-2007, and California’s Title 24. The number of code bodies and programs referencing SRI is quickly growing due to its single value simplicity in communicating the energy performance of roofing products. With this addition to the Rated Products Directory, the CRRC is providing verified and credible SRI values for architects, roofing consultants, and home/building owners to identify and specify cool roofs.
Please note that the SRI values are calculated using the posted CRRC solar reflectance values, utilizing ASTM C1549, CRRC Test Method #1, or E1918, and the posted CRRC thermal emittance values, using ASTM C1371.
The CRRC has also been selected to hold a press release conference about the addition of SRI to our Rated Products Directory at the Greenbuild Conference in Chicago on November 18, 2010. You can read the press release in its entirety here.
We have received several messages from people interested in cool roofs due to a widely circulated article touting cool roofs as a quick, instantly effective solution for saving energy in the summer and fall heat. The article reached several readers as a feature on CNBC and the Washington Post and can be read in its entirety here.
In the article, the author joins a group of volunteers participating in New York City’s Cool Roofs program, which aims to coat one million square feet of roofs this year. The volunteers coated a retirement home with a cool coating that is expected to lower the roof surface temperature by 50 to 60 degrees. The article outlines pivotal cool roof legislation around the country and cites former California Energy Commissioner Art Rosenfeld, who states that 1,000 square feet of roofing painted white can save ten tons of carbon dioxide, or the equivalent of taking one car off the road for two and a half years.
The online Renewals system will be open to all CRRC participants starting November 17th. All Licensees and Members will receive an email with a login and password for their online Renewal payment process. This is our third year offering online Renewals and we have made further improvements to the system. We are continuing to accept credit card payments through Google Checkout. You also have the option to send us a check.
Please note that this year Renewal payments are due February 1, 2011. To encourage timely payments and maintain an equitable process for licensees who do pay before the deadline, the CRRC will continue enforcing a nominal late fee charge. The late fee charge is 1% of your total payment per month; therefore, it will accrue by 1% for each additional month that the payment is late. The late fee structure is as follows:
| Payment received by
| February 1, 2011
| March 1, 2011
||1% of total payment
| April 1, 2011
||2% of total payment
| May 1, 2011
||Termination with a 3% of total payment
If payment is not received by May 1, 2011 we will terminate membership and/or licensee status and all products, as applicable. In order to reinstate your status after termination, companies must pay the full renewals invoice amount in addition to a reactivation fee.
If you have any questions or concerns at any point in the Renewals process, please do not hesitate to contact Alexis at email@example.com or (510) 482-4420 x279.
The CRRC Technical Committee held two meetings this fall: a conference call on August 4th, and an in-person meeting in San Francisco on September 29th. The next scheduled meeting will be a conference call in March 2011. Technical Committee meetings are open to all interested participants. If you would like to be added to the Technical Topics mailing list, please contact Jennifer Wang at firstname.lastname@example.org.
The CRRC is conducting several ongoing studies. Two of these studies, a Round Robin study of the Transient Method Modification for C1371 and a study of E1918 using an indoor solar simulator at Atlas Weathering Services Group, are expected to be completed by January 2011. For more information on these studies, please contact Karl Skare at email@example.com.
Ratings for Cedar Roofing Products
The CRRC is working with the Cedar Shake and Shingle Bureau to develop a rating method for cedar roofing products. Natural wood products present some new challenges in solar performance rating, due to the inherent color variability, significant color change after aging, and other material properties. CRRC staff are working with the Bureau to gather some preliminary data in order to help inform the Technical Committee in their efforts to develop a rating procedure for these products.
Predictive Aging Formulas
The Cool Metal Roofing Coalition has presented to the CRRC a proposal for a mathematical calculation to predict the impact of aging on the solar performance of coated metal products. The Technical Committee discussed this proposal during the September 29, 2010 meeting and agreed that the CRRC should research the development of predictive aging formulas for all product types. A Technical Committee task group has convened to develop a quality assurance program that can ensure ongoing rigor for products that receive a calculated aged rating. If you would like to be involved in this task group, please contact Jennifer Wang at firstname.lastname@example.org.
Coordination with ENERGY STAR
ENERGY STAR, which is managed by the Environmental Protection Agency (EPA), is currently developing a verification program for all product programs. The CRRC has been working with the EPA towards coordinating the ENERGY STAR roofing program with the existing CRRC rating program. For more information, please see the September BOD Meeting Update in this newsletter, or contact Sherry Hao at email@example.com.
V6 Reflectometer Study
A new Reflectometer has been released which is designed to yield more accurate Solar Reflectance readings than the V5 Reflectometer. The CRRC is currently performing a study to compare the SR calculated by the V6 Reflectometer to the SR calculated by the V5 Reflectometer. The V6 Reflectometer also features an emulation mode which is designed to reproduce the results that V5 would have generated for that sample. In this study, the V6 emulation mode results will also be compared to those of V5 to see how well V6 is able to replicate V5 results.
Please note, the V5 Reflectometer has been used to produce the majority of CRRC reflectance ratings. For those AITLs who have purchased or upgraded their reflectometer to version 6, we are asking them to produce ratings using the V5 emulation mode to ensure consistency across CRRC ratings. This policy will be employed until the CRRC Technical Committee and Board have had a chance to discuss the Reflectometer Study analysis.
Ratings, Codes and Programs
In early October, the CRRC submitted a comment letter to the EPA regarding the draft Partner Commitment and Product Specification for Roofing Products. We highlighted our concerns with the proposed roofing product program specifications, as the draft proposal contains conflicting on–site test protocol and methods from the current CRRC program. The CRRC encourages all our members and licensees to be active in the EPA verification development process, especially during this period where EPA is formulating the criteria for the Qualified Roof Program.
Please monitor the EPA verification webpage for updates (www.energystar.gov/testingandverification), or sign up with the EPA to receive notices.
Rosemont-Petite Patrie, a borough in Montreal, may become the newest jurisdiction with a cool roof mandate. Mayor Francois Croteau has proposed a bylaw requiring all new roofs to be cool. Croteau cites public health, environmental and energy efficiency benefits. According to the article, currently about 121 Montrealers pass away due to extreme heat and 818 from air pollution related diseases each year. If temperatures increase, the Urban Heat Island Effect and global warming could amplify these numbers by 30 percent by 2050. Croteau believes the bylaw will be easily passed. More details about the proposed law can be read in the Montreal Gazette here.
In this edition we are delighted to welcome a guest submission by Amy Dickie, Senior Associate at California Environmental Associates, announcing the creation of the White Roofs Alliance.
We are pleased to announce the launch of the White Roofs Alliance, a new global initiative dedicated to advancing policies and actions that increase the solar reflectance of our buildings and pavements as a low– or no–cost way to promote cool buildings, cool cities, and, most importantly, to mitigate the effects of climate change through global cooling.
The White Roofs Alliance (WRA) will pursue this mission through the development of five different program areas which together are designed to ensure that a range of mechanisms, from municipal action to advancements in research and development, act in concert to accelerate the adoption of cool roofs. Specifically, WRA will work towards the following actions:
||100 Cool Cities– Recruit and obtain commitments from 100 major cities – “100 Cool Cities” – across the globe by 2015, with widespread installation of cool surfaces by 2020.
||National action - Advance national regulatory and legislative actions that support the implementation of cool surfaces by 2020, in the US and other key countries.
||Building and pavement codes – Promote the inclusion of cool surfaces, such as white roofs, in all US and international building and pavement codes globally by 2015, with initial focus on US, China and India.
||Financial mechanisms – Develop financial mechanisms that broadly support the installation of cool surfaces by 2015, in the US and other key countries.
||Research and development - Ensure that research and development on cool surfaces is well supported and well disseminated.
The White Roofs Alliance was launched in the summer of 2010 and is currently working to build its programs. Already, WRA has provided technical input into the energy and finance bills before the US Congress in the summer and fall of 2010, and secured three founding members of its 100 Cool Cities network (Athens, New York City, and Taipei).
The White Roofs Alliance looks forward to collaborating with the Cool Roof Rating Council.

Membership and Outreach
The Board participated in a September 21st conference call meeting where the following topics were discussed:
Class B Board Position Vacancy
Richard Lee announced his resignation from his position as a Class B Board member, opening up the discussion for Board members to determine who would fill this vacancy. The Board reviewed a handful of eligible and qualified candidates. Roofing Consultants Institute (RCI) representative Phil Dregger was selected to serve in this capacity. In early October Phil Dregger accepted the Class B position, agreeing to complete Richard Lee’s term until 2012. As customary under CRRC protocol, the membership must vote to approve Phil Dregger in the 2011 election.
The CRRC would like to take this opportunity to thank Richard Lee for the time and effort he dedicated to the CRRC as a Board member (from 2007 to 2010), as well as our Board Chairman (from 2008 to 2009).
CRRC & ENERGY STAR
On August 31st, the EPA released their final criteria for Certification Bodies, as well as the application to become an EPA accredited Certification Body (www.energystar.gov/testingandverification).
The CRRC, as a third party rating system for roofing materials, is eligible to serve as an EPA Certification Body for their Qualified Roof Program. At the September BOD meeting, the Board discussed the benefits and potential barriers to the CRRC taking on this role with ENERGY STAR and voted to approve the CRRC applying to become an EPA Certification Body. In order to be accepted as a Certification Body, the CRRC must also become ISO 65 accredited. Therefore, in the coming months the CRRC will apply to both accreditation processes.
The next Board meeting is scheduled as an in-person meeting on November 19th, in conjunction with the Greenbuild Conference. The BOD meeting will be held at the Chicago South Loop Hotel. If you are interested in attending this meeting, please email Sherry Hao at firstname.lastname@example.org to register.
This section provides Class B members an opportunity to share their insights on trends and new developments in the cool roofing industry. In this edition we are pleased to bring you an inside look at our two accredited test farms. The first contribution is from Matthew Friday, Technical Director at Q-Lab Weathering Research Service. The second is from Rich Slomko, NA Testing Leader of Atlas Weathering Services Group.
A Test Farm in the 21st Century —
Q–Lab Weathering Research Service
Test Farm is a term that has been used in the weathering industry for many years. It may have originated from the observation that rows of exposure racks resemble rows of crops. Exposure racks were originally called Test Fences. For architectural coatings, exposures were often conducted on vertical wooden racks to simulate the side of a house. As one would expect, these racks resembled fences; hence the term Test Fence. Later it was discovered that a rack tilted at an angle, such as 45°, would receive more solar radiation. Racks tilted to 45° do not resemble a fence but the term Test Fence is still used by some industries.
Test Farms are much more sophisticated than they were in the early days of outdoor weathering tests. To illustrate this let’s take a look at the life of a test specimen at Q-Lab Weathering Research Service.
Instead of using pen, paper and a calendar to schedule steps in the testing process, a scheduling database is used. All of the important information such as type of exposure, angle of exposure, backing type, exposure duration, and evaluation interval are entered in the scheduling database. The laboratory staff is automatically alerted when an action is due for each specimen. Each specimen is assigned a unique serial number for identification throughout the life of the test. A barcode label containing this serial number as well as other useful information about the test is attached to each specimen. The barcode label is used to verify the identification of the panel at each step of the testing process.
The exposure period of the specimen may seem like the most basic part of the test process, but there is still a tremendous amount of activity during this phase. Specimens are exposed on specially built racks per the test method (such as ASTM G7) being followed. Racks are typically constructed from anodized aluminum instead of wood.
The three major factors in weathering degradation are radiation, temperature, and moisture. At the test farm, a weather station continually measures and records in a database weather parameters including total solar radiation, UV radiation, air temperature, humidity, panel temperatures, time of wetness, and rainfall. This data can be used to compare exposures from different time periods and in the development of correlation of outdoor weathering to accelerated weathering.
Evaluation and Return
After the appropriate exposure interval, the scheduling database will automatically indicate that the specimens need to be evaluated and/or returned to the customer. The Test Farm can perform a number of evaluation techniques to detect and quantify the degradation of materials. Visual inspections and ratings can be performed according to various standards such as ASTM and ISO. Instrumental measurements of color with a spectrophotometer provide the customer with a set of numbers that quantify the amount of color change that occurred during the exposure. A separate instrument measures the gloss of the specimen surface. Quantifying the change in color and gloss helps chemists adjust the chemical formulation to develop a more durable material.
There is more to a Test Farm than the name implies. Advances in technology and scientific understanding have evolved the Test Farm into a truly scientific laboratory.
