General Updates / Administrative
The CRRC is proud to announce the re-election of Class A Board members Gregory Crawford (American Iron and Steel Institute) and Mike Ennis (SPRI) and Class B Board member Richard Lee (Momentum Technologies). We would also like to recognize the confirmation of the Board’s appointment of Class B Board member George Malek (Commonwealth Edison) by the membership.
We would like to thank everyone who participated in the election; it was a very close and exciting election! We look forward to another good year being led by the CRRC Board of Directors! For a full list of Board Members please visit: http://coolroofs.org/aboutthecrrc_boardofdirectors.html.
The CRRC would like to (kindly) remind CRRC Members and Licensed Sellers of proper logo and label use. Please find below a brief summary of requirements that should help clarify any concerns or questions regarding the proper application of the CRRC logo and product label.
CRRC Member Logo
- The CRRC logo is strictly for CRRC Members in good standing. Members in good standing are entities that have submitted a Membership Application, signed the Member Logo License Agreement, been approved by the CRRC, and paid in full the current membership dues.
- The logo can be used on company letterheads and general company promotional materials as specified on our “How Do I Use the CRRC Logo”, which can be viewed here .
- The logo cannot be applied to any product or product packaging or used in any way that can be misconstrued as an endorsement of the product.
CRRC Product Label
- Licensed Sellers (LS) with products in good standing are eligible to use the CRRC label.
- The text within the CRRC product label cannot be edited and the LS must fill in the product ID, LS ID number, and radiative property information.
- The CRRC product label may be used on the product, product packaging, and with the rated products promotional materials. For details on how to properly use the Product Label, please read HDI-Label.
- The CRRC product label may not be displayed next to other trademarks, brands, labels, symbols, or logos.
Misuse of the CRRC logo (membership mark) and product rating label may result in the CRRC revoking a company’s privileges to use the logo or label. If you are improperly using a label or logo and would like assistance in correcting the problem or if there are any further concerns, the CRRC staff will gladly review any materials to assess proper placement or answer your questions.
The CRRC would like to note that at the June 16, 2009 Board meeting, the Board approved the inclusion of a Rated Products Logo to be added to the repertoire of CRRC logos. The addition of this logo may alleviate many of the logo violations that currently occur, as it will be acceptable to use this logo on product specific materials. CRRC will keep licensees informed on the progress of the Rated Products Logo as it becomes developed. We anticipate it to become available in the fall of 2009.
The CRRC Technical Committee held its first in-person meeting of 2009 in Washington, DC on April 29. Meeting business included updates on ongoing studies, Technical Committee administrative changes, and changes to the CRRC-1 Rating Program. Meeting highlights include:
Technical Committee Guidelines
The Technical Committee voted to approve guidelines for conducting and submitting research to the Committee, including data formatting requirements and deadlines for submission of presentations at Technical Committee meetings. These guidelines are intended to improve coordination and scheduling, and make research accessible even years after it has been presented. Guidelines specifics include:
- Data provided for every assertion, in Excel format, 2 weeks prior to Technical Committee meeting.
- Summary sheet with investigation methods, 2 weeks prior to Technical Committee meeting.
- Analysis and conclusions supported by evidence, 1 week prior to Technical Committee meeting.
AITL Probationary Process
As the CRRC grows and the number of licensees, members, rated products, and AITLs increases, staff are working to develop fair and consistent internal procedures. The CRRC currently has no formal process for handling concerns or complaints regarding AITL performance. While we have never had a significant problem with any of our AITL partners, staff have encountered occasional cases of mis-applied test methods or improper procedure. At the Technical Committee meeting staff presented a first draft proposal for an AITL probationary process that would set clear guidelines for determining if an error has occurred and, if so, addressing it. The Technical Committee made a number of modifications to the proposal in order to minimize subjectivity and ensure that all parties are fully aware of their responsibilities during the product rating process; the revised proposal was approved by the Technical Committee for submission to the Board of Directors.
Rating Granules as Stand-Alone Products
In early 2009 the CRRC received its first product rating application from a manufacturer who makes coated roofing aggregate. The manufacturer sells its products through distributors and has no control over the adhesive used when the aggregate is applied to a particular building. The Technical Committee discussed the requirements for sample preparation when testing such a product and determined that the Licensee must specify the aggregate model number, size, and application rate in pounds per square foot, as well as the adhesive used in the sample. The resultant rating will only be valid for that particular combination of aggregate and adhesive.
DOE Grant Funding
The American Recovery and Reinvestment Act of 2009 set aside a large quantity of funds for the Department of Energy (DOE) to use in energy efficiency research. A portion of these funds have been given to the DOE Building Envelope Program to distribute through a competitive grant process. The DOE has begun accepting grant proposals for this money, with the closing date for applications on August 18, 2009.
CRRC staff prepared a list of potential projects to include in a grant funding request to the DOE Building Envelope Program and presented these projects to the Technical Committee. The Committee approved a recommendation to the Board that the CRRC submit a grant proposal to the DOE for the following projects:
- A study on the validity of Solar Reflectance Index (SRI) as a predictor of cool roof performance.
- A study on the use of calculated methods to predict the solar reflectance of asphalt shingles.
- Case studies documenting the energy savings in specific real buildings after installing a cool roof.
- Continuing research on developing a solar reflectance test method that can be used with high-profile materials.
- Subsidizing the CRRC lab training program in order to encourage participation and provide an accessible educational resource.
Analysis of Aged Rating Data
The Technical Committee voted to recommend to the Board a research study analyzing the three-year aged data currently available on the CRRC Rated Products Directory. The purpose behind this study is to determine if there are calculable patterns in how roofing products weather over time.
Ratings, Codes and Programs
The ANSI Second Public Review and Consensus Body review closed May 28, 2009. All members of the public and the Consensus Body were able to submit comments on the significant revisions from the First Public Review. The Consensus Body held a conference call on June 12, 2009 to review and vote on the comments. The Consensus Body continues to proceed toward consensus achievement and is aiming to submit the proposed standard for final approval to the CRRC Board of Directors by Fall 2009.
Informative documents are available for review at http://coolroofs.org/StandardReview.html .
What is the CRRC-1 Standard?
The CRRC-1 Standard is a standard for the measurement of initial and aged solar reflectance and thermal emittance of roofing products. It is the portion of the CRRC’s Program Manual that describes sample preparation and testing procedures.
What is ANSI?
The American National Standards Institute (ANSI) is a distinguished non-profit organization that coordinates the development of voluntary consensus standards through its Essential Requirements, which require the process for standards development to be fair, open, and balanced.
A revised version of draft ASHRAE/USGBC Standard 189.1, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, was released in May 2009. Section 22.214.171.124, the roofs portion of the Mitigation of Heat Island Effect section, refers specifically to cool roofing standards (see below for full text excerpt).
Of note, there is an exception that allows a non-cool roof to be used if it can be shown, through simulation, that the non-cool roof has at least 2% less annual energy cost and CO2 production than a qualifying cool roof would. This exception takes into account the fact that a cool roof is not always the most energy efficient option and that appropriate building techniques depend on many factors, especially climate. Along these lines, the standards for cool roofs refer only to climate zones 1, 2, 3, and 4, in recognition of the importance of climate in the efficacy of cool roofing as an urban heat island mitigation strategy.
Furthermore, this revision requires that a roofing product’s solar reflectance and thermal emittance properties are tested through an accredited, nationally recognized, laboratory and cites the CRRC as a viable option.
5.3.2 Mitigation of Heat Island Effect.
126.96.36.199 Roofs. This section applies to the building and covered parking roof surfaces for building projects in climate zones 1, 2, 3 and 4. A minimum of 75% of the entire roof surface not used for roof penetrations and associated equipment, on-site renewable energy systems such as photovoltaics or solar thermal energy collectors, portions of the roof used to capture heat for building energy technologies, harvesting systems for rainwater collection and reuse, rooftop decks or walkways, or green roofing systems shall be covered with products that comply with one or more of the following:
a. have a minimum initial SRI of 78 for a low-sloped roof (a slope less than or equal to 2:12) and a minimum initial SRI of 29 for a steep-sloped roof (a slope of more than 2:12).
b. comply with the criteria for the USEPA’s Energy Star Program Requirements for Roof Products – Eligibility Criteria.
Exceptions to 188.8.131.52:
1. Building projects where an annual energy analysis simulation demonstrates that the total annual building energy cost and total annual CO2e, as calculated in accordance with 7.5.2 and 7.5.3, are both a minimum of 2% less for the proposed roof than for a roof material complying with the requirements of 184.108.40.206(a), or
2. Roofs used to shade or cover parking and roofs over semi-heated spaces provided that they have a minimum initial SRI of 29. A default SRI value of 35 for new concrete without added color pigment is allowed to be used instead of measurements.
220.127.116.11 Solar Reflectance Index.
The solar reflectance index (SRI) shall be calculated in accordance with ASTM E1980 for medium-speed wind conditions. The SRI shall be based upon solar reflectance as measured in accordance with ASTM E1918 or ASTM C1549, and the thermal emittance as measured in accordance with ASTM E408 or ASTM C1371.
For roofing products, the values for solar reflectance and thermal emittance shall be determined by a laboratory accredited by a nationally recognized accreditation organization, such as the Cool Roof Rating Council CRRC-1 Product Rating Program, and shall be labeled and certified by the manufacturer.
For building materials other than roofing products, the values for solar reflectance and thermal emittance shall be determined by an independent third party.
This past June the California Energy Commission announced that the effective date for the 2008 Building Energy Efficiency Standards (Title 24, Parts 1 and 6) has been changed to January 1, 2010.
The California Energy Commission adopted the 2008 Standards on April 23, 2008, and the Building Standards Commission approved them on September 11, 2008. The Standards were scheduled to become effective on August 1, 2009. The delays are due to the need for further programming attention for the public domain compliance software. As the CEC website states, this delay provides the industry and building officials more time to prepare for the new standards.
If you have specific questions about Title 24, please contact:

On June 26, 2009 the House of Representatives passed the American Clean Energy and Security Act, also known as the Waxman-Markey Clean Energy Bill. The new bill is designed to boost our economy by creating millions of new jobs, reducing our dependence on foreign oil, and reducing carbon emissions to mitigate climate change.
A few key bill provisions include:
- Requires electric utilities to meet 15% of their electricity demand through renewable energy sources by 2020.
- Invests $190 billion in new clean energy technologies and energy efficiency.
- Mandates new energy saving standards for appliances, buildings, and industry.
- Reduces carbon emissions from major U.S. sources by 17% by 2020 and by 83% in 2050 compared to 2005 levels.
- Protects consumers from increased energy prices.
Language specific to cool roofs is as follows:
‘(C) CONSIDERATIONS- In developing a national energy efficiency building code under this paragraph, the Secretary shall consider-
‘(i) for residential codes-
‘(VII) standards for practices and materials to achieve cool roofs in residential buildings, taking into consideration reduced air conditioning energy use as a function of cool roofs, the potential reduction in global warming from increased solar reflectance from buildings, and cool roofs criteria in State and local building codes and in national and local voluntary programs; and
‘(ii) for commercial codes-
‘(VII) standards for practices and materials to achieve cool roofs in commercial buildings, taking into consideration reduced air conditioning energy use as a function of cool roofs, the potential reduction in global warming from increased solar reflectance from buildings, and cool roofs criteria in State and local building codes and in national and local voluntary programs.
The Waxman-Markey bill, aimed at tackling climate change, is the first legislation of its kind in the U.S. “Today we have taken decisive and historic action to promote America’s energy security and to create millions of clean energy jobs that will drive our economic recovery and long-term growth,” stated Chairman Waxman as the bill was passed through the House. The Act now goes to the Senate, where a vote could take place this fall.
Membership and Outreach
The CRRC held its annual Membership meeting on June 17 in Reno, Nevada. The presentations (available at:http://www.coolroofs.org/vents.html) included:
CRRC Administrative Update & Technical Program Update
The administrative update covered organizational growth over the past year, staff transitions, marketing and outreach efforts (tradeshows, articles, CE course, newsletters and presentations), codes and programs responses (specifically to LEED 2009 and ICC-ES), and updates on random testing, ANSI process, and the strategic planning process. The technical program update reviewed the past year CRRC—1rating program changes, ongoing research studies and technical committee administrative updates. For full coverage of these updates, please open the presentations linked above.
CRRC Membership Discussion on Expanding to Rate Non-Roof Surfaces
The CRRC membership held a lively discussion on the possibility of expanding the organization to rate other surfaces beyond roofing. Mike Ennis, CRRC Vice Chairman and the Strategic Planning Committee Chairman, presented the opportunity for the CRRC to expand in this new direction, outlining the upcoming trends in codes and programs, the benefits to the CRRC membership and organization, the plan for expansion, and next steps. Andre Desjarlais from Oak Ridge National Laboratories presented the impact of rating cool wall products. Mr. Ennis explained that in order to pursue this expansion, the CRRC would need membership approval to change our governing documents, which currently specify rating roofing products. A straw poll vote was held to assess the interest level of CRRC membership in pursuing this initiative. The vote concluded with the majority against expansion to rate non-roof surfaces.
Codes & Programs Update
Mike Ennis next provided the membership an update on current codes and programs with cool roofing sections, focusing on ASHRAE 90.1 & addendum f, 90.2, 189.1, Advanced Energy Design Guides, and concluding with the LEED 2009 program. Amended cool roof sections for the membership to note include 90.1 addendum f (includes minimum initial and aged values; a formula for products that have not completed aged testing; exempted roof types) and the 3rd draft of 189.1 (climate zones, 1, 2, 3, 4; min 75% cool roof; low slope SRI-78; steep slope SRI-29).
Ms. Neelam Patel, Heat Island Program Manager, Climate and Energy Expert for the US Environmental Protection Agency, presented to the CRRC membership the current work of the EPA’s Heat Island Reduction Program. The Heat Island Program is focusing its mitigation strategies on tree and vegetation, green roofs, cool roofs and cool pavement. Ms. Patel also reviewed EPA’s ENERGY STAR program, current legislative activity with the Waxman-Markey Bill, and funding opportunities under the American Recovery and Reinvestment Act and the EPA Climate Showcase Communities Grant.
Ms. Aleisha Khan is the Executive Director for the Building Codes and Assistance Project. Ms. Khan focused her presentation on upcoming opportunities in energy codes, specific to new technologies in roofing. BCAP is a non-profit advocacy group that provides resources, education and advocacy assistance for the adoption and implementation of energy codes. Ms. Khan explained the movement of codes toward zero-net energy, touched on the details and upcoming proposals for the Waxman-Markey Bill, 90.1-2010, and 2012 IECC.
Mr. Corey Enck, Director for the LEED Rating System Development for the US Green Building Council, provided an overview of USGBC and the LEED program, covered LEED 2009 (V3), including the credit 7.2 Sustainable Sites roof section, discussed Regional Priority Credits, and reviewed LEED educational resources.
On June 16th, the Board held an in-person meeting in Reno, Nevada. The meeting commenced with recognition of the re-elected Board members from the recent Election (Greg Crawford, Mike Ennis and Rich Lee, as well as confirmation of George Malek), followed by re-election of each current officer. Therefore the 2009 Board Officer positions are as follows:
Richard Lee, Chairman
Mike Ennis, Vice Chairman
Marty Hastings, Treasurer
Greg Crawford, Secretary
Jonathan Humble, Ratings, Codes & Programs Chair
William Kirn, Technical Committee Chair
In addition to approving the Board officer positions, the Board voted on the 2009 Technical Committee Voting Members and their Alternates. The meeting also included a discussion of the Strategic Plan, in which a draft version was presented by the Planning Committee for Board review. The Board will take the next couple of months to review the Plan in preparation for discussion at the September Board meeting.
The Board voted to approve an AITL probation process to shore up CRRC procedures, as well as the addition of a CRRC extended label (allowing up to four products to be placed on a label) and a Rated Products logo. Firestone representatives attended the Board meeting to discuss the possibility of adding Solar Reflectance Index (SRI) to the CRRC Rated Products Directory. The discussion brought up both positive reasons for the CRRC to include SRI, as well as concerns with the SRI formula and the complexity of including the SRI on our directory. The SRI discussion will be continued at the September meeting.
As a reminder to the CRRC community, if you have a discussion topic that you would like the Board to address, please approach CRRC staff and we will work to include it on the next coming meeting agenda. Board meetings occur roughly every other month, alternating between conference calls and in-person meetings. There is no fee associated with attending a CRRC Board meeting, but there are nominal fees to attend CRRC Technical Committee in-person meetings as well as the Annual Membership meeting.
