Thanks to all CRRC participants who have completed their 2010 Renewals by the January 1st deadline! This is our second year using the online Renewals system and we hope to continue making improvements in the future. We were excited to introduce credit card payments this year, both for renewals payments and for new application fees.
If payment is not received by April 1, 2010, 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. Increasing Test Farm Product Placement FrequencyThe CRRC Board of Directors has voted to increase the frequency of Test Farm product placement from quarterly to every other month. The increase in placement dates should help AITLs and Licensees to plan and submit new products for aged ratings. The Test Farms have agreed to implement this new policy starting March 1, 2010. Product placements will then occur every other month (May 1, July 1, September 1, and November 1, and so on). Choosing Brand Name and Model Name
Initial Product Rating Application (CRRC Form F-3) is essential for product rating listings. While filling out the F-3 form, you will come across Box 10 where you will be asked to enter: Clarification of Random Testing Program

Section A5.205.3.9, page 112, states exceptions for roofing products not certified shall assume the following default reflectance/emittance values:
Asphalt shingles = 0.08/0.75
All other roofing products = 0.10/0.75
The CALGreen Code also sets VOC content limits for roof coatings (Table 4.504.3 and 5.504.4.3), as well as VOC limits for sealants and adhesives (Table 4.504.2 and 5.504.4.1). Section A5.205.3.9.4 of the code details liquid applied coating specifications.

The Sustainable Building Technology Council (SBTC) is in the process of producing a first draft of the International Green Construction Code (IgCC). A draft for public comment is scheduled to be released in March 2010, and public comments will be due in May 2010. Version 4 of the IgCC draft states that 75% of the roof surface of buildings located in climate zones 1-3 shall be covered with a combination of vegetative roofing, solar collectors, and cool roofing. In order to qualify as a cool roof, values for solar reflectance and thermal emittance must be determined by an independent laboratory accredited by the CRRC or other nationally recognized accreditation programs. SRI values may be used as long as the value is determined using ASTM E1980 with a convection coefficient of 2.1 Btu/h-ft2 (12 W/m2*k) tested in accordance with the CRRC-1 Standard. The minimum solar reflectance, thermal emittance, and SRI values for cool roofs can be found in the table below and more details can be found in section 404.3.1 of the draft.

In December 2009, Standard 189.1 (Standard for the Design of High Performance, Green Buildings Except Low-Rise Residential Buildings) was approved for publication by the Boards of Directors of ASHRAE, IES and USGBC. This standard will provide a uniform, comprehensive code for green buildings. The proposed code requires an initial SRI of 78 for low-slope roofs and initial SRI of 29 for steep-slope roofs, with some exceptions. It applies to climate zones 1- 3 (South and Southwest areas; a map of DOE’s climate zones can be viewed here. Publication is expected in February 2010. ASHRAE has launched a website to track this standard: http://www.ashrae.org/greenstandard
ASHRAE and IES are working to strengthen the requirements in ANSI / ASHRAE / IESNA Standard 90.1 (Energy Standard for Buildings Except Low-Rise Residential Buildings) which provides minimum requirements for the energy-efficient design of nonresidential buildings. ASHRAE’s goal for the 2010 standard is 30% energy savings over the 2004 version. The proposed standard contains new mandatory prescriptive requirements for cool roofs, including a minimum three-year aged reflectance of 0.55, and a minimum aged emittance of 0.75. The 2010 standard is expected to be released in fall 2010.
As of January 1, 2010, updates to California's Energy Efficiency Standards are in effect, superseding the 2005 Standards. Section 118(i) includes updated minimum reflectance and emittance requirements for cool roofs, which are limited to certain climate zones.
Other relevant updates include:
• The use of minimum SRI (Solar Reflectance Index) values as an alternative to reflectance and emittance values.
• The use of three-year aged data for reflectance values.
• Default roof emittance and reflectance values assumed for products not certified by the CRRC.
• Distinct requirements for steep-slope (greater than 2:12) nonresidential roofs and for residential roofs.
• Less stringent requirements for steep-slope roofs with a minimum surface weight 5 lbs / ft2.
The full text of the code is available at the California Energy Commission website at http://www.energy.ca.gov/title24/.
The CRRC is no longer the only Cool Roof Council on the block. The European Union has started its own Cool Roofs Council (EU-CRC) under the guidance of Hashem Akbari, ex-officio CRRC Board member and founding member of the CRRC. The stated goals of the EU-CRC are to:
• Support policy development by improving understanding of the actual and potential contributions by cool roofs to heating and cooling consumption in the EU.
• Remove market barriers and simplify the procedures for the integration of cool roofs in construction.
• Change the behavior of decision-makers and stakeholders to improve acceptance of cool roofing technologies.
• Promote the development of innovative legislation, codes, permits and standards concerning cool roofs.
The EU-CRC is also in the process of developing its own database of cool roofing products which currently includes over 100 products from six companies in Germany, Greece and Italy. The minimum requirements to be listed in the database will be determined by a combination of factors including the product performance with respect to the roof slope and the effects of aging on the materials. In addition to creating this database, the EU-CRC is working to identify the potential policy issues and opportunities for introducing cool roof technology in the EU based on lessons learned from the introduction of cool roofing standards in the United States.
The CRRC is looking forward to working with our counterpart in the European Union to promote the adoption of cool roofing products around the world. To learn more visit http://coolroofs-eu.eu/.
The Building Codes Assistance Project (BCAP) at the Alliance to Save Energy recently launched its new Online Code Environment & Advocacy Network (OCEAN) website. OCEAN is an interactive, Web-based resource designed to share lessons learned, best practices, educational resources and key facts as they relate to building energy code adoption and implementation. You can visit BCAP’s new website at http://bcap-ocean.org/ or go directly to the new state code status page http://bcap-ocean.org/code-status.
On November 10th, 2009 the Board held an in-person meeting in Phoenix, Arizona, in conjunction with the Greenbuild Conference. On January 7, 2010 the Board held a conference call meeting to kick off the New Year. Both agendas were jam packed with discussion items, resulting in the following key decisions:
Technical Committee Voting Member Attendance Policy
The Board approved the protocol for Technical Committee voting members and their alternates. The Board also recommended that staff notify a voting member if they are one missed meeting short of losing their voting status. Please see the Technical Update above for more details.
SRI on the Directory
The Board approved the request to add Solar Reflectance Index values to the Rated Products Directory. Specifically the CRRC will add initial and aged SRI columns to the Directory using medium wind speed, with a footnote stating the reflectance and emittance test methods. Please see the Technical Update section above for more details.
Strategic Plan
The Board recommended modifications to the CRRC Strategic Plan, which had originally been presented by the Strategic Planning Committee at the June Board 2009 meeting. The Board approved moving forward with two sections of the Strategic Plan: Improvements to the Existing Program and International Expansion. The Strategic Planning Committee will review the suggested edits by the Board for a follow-up discussion at the February Board meeting.
Compound Ratings
In November 2009, the Board approved compound ratings for shingles and modified bitumen products. The Board also recommended researching the weatherization effects on different shingle shapes with a study to expose a variety of shingles on the test farms for three years. In January 2010, the Board clarified the language for modified bitumen compound ratings (see below for the full Board-approved language for both shingles and mod-bit products). The Technical Committee and Board will revisit the compound rating language for modified bitumen products at the March 2010 TC meeting and June 2010 Board meeting.
LANGUAGE TO BE ADDED TO THE CRRC-1 PROGRAM MANUAL
3.5.1 B (Non-Variegated)
7. Shingle Products: If a Licensed Seller or Licensed OM has multiple shingle products with the same exposed color blend granule formulation, the solar reflectance and thermal emittance ratings for the tested product may be applied to these other products. The Licensed Seller or Licensed OM submitting the shingle product for certification must declare as part of their application any differences such as varying granule distributions, the non-exposed shingle system components, or design features.
8. Modified Bitumen Products: If a Licensed Seller or Licensed OM has modified bitumen products whose granules have the same color blend formulation and size, solar reflectance, and thermal emittance and/or whose factory applied coatings have the same coverage rate and formulation, the solar reflectance and thermal emittance ratings for the tested product may be applied to these other products. The Licensed Seller or Licensed OM submitting the modified bitumen product for certification must declare as part of their application any differences in the non-exposed system components or design features.
3.5.1 B1
In order for a shingle or modified bitumen product to qualify for a Compound Product Rating at least one product with the same surface formulation must be rated.
3.5.5 B (Variegated)
3. Shingle Products: If a Licensed Seller or Licensed OM has multiple shingle products with the same exposed color blend granule formulation, the solar reflectance and thermal emittance ratings for the tested product may be applied to these other products. The Licensed Seller or Licensed OM submitting the shingle product for certification must declare as part of their application any differences such as varying granule distributions, the non-exposed shingle system components, or design features.
AITL & TF Separation Policy
The Board decided to create a written policy to memorialize longstanding CRRC practice to keep Independent Testing Laboratories and Test Farms separate and not allow an AITL/TF combination within the CRRC program. The language separating these two entities will be added to the AITL and Test Farm Agreements, as well as the CRRC-1 Program Manual under Chapter 2.
Test Farm Product Placement Dates
The Board approved increasing the test farm product placement frequency to every other month from its current quarterly frequency with the suggestion that the CRRC monitor for variation in measurements resulting from the change in frequency. Please see the General Updates section on placement frequency above for more details.
AITL/TF Subcommittee
The Board approved the formation of an Accredited Independent Testing Laboratory and Test Farm Subcommittee to provide input on technical issues that are presented to the Technical Committee. After a six month trial period the Board will assess the efficiency of the addition of this Subcommittee to the CRRC organizational structure. Please see the article on Changes to the Technical Committee Structure below for more details.
Technical Committee Meeting Fees
The Board voted to eliminate fees to attend Technical Committee meetings for TC voting members and their alternates. AITLS and TFs, as subcommittee members, will be exempt from paying the Technical Committee meeting fee. Non-voting or non-alternate member meeting attendees will be charged a meeting fee.
Renewals Late Fee Charge
In January the Board approved the addition of a late fee charge to the annual renewals invoice process. Please see the General Updates section above for more information.
Next CRRC Board meeting:
February 25, 2010 in New Orleans, LA.
To register for the February 25th Board meeting, please email sherry@coolroofs.org.
A new subcommittee designed to elicit feedback from Accredited Independent Testing Laboratory (AITL) and Test Farm (TF) representatives has been created to advise the Technical Committee. This subcommittee will consist solely of AITL and TF representatives and will be responsible for investigating technical issues at the request of the Technical Committee or CRRC staff. CRRC staff will convey the recommendations of the AITL/TF subcommittee to the Technical Committee members for Technical Committee meetings.
The CRRC had a booth on the tradeshow floor at the Greenbuild Expo on November 10, 11, and 12, 2009. The conference and tradeshow were held at the Phoenix Convention Center in Phoenix, AZ. The booth was staffed by Molly Trombley-McCann, Sherry Hao, and Alexis Wong.
This was a very well-attended tradeshow. We noticed particular interest in information on the new Title 24 regulations that will go into effect on January 1, 2010. We also noticed many representatives of the armed services looking for ways to make their facilities more sustainable and energy efficient. During the tradeshow we visited the booths of manufacturers who have not yet rated their products with the CRRC and spoke to them about their needs and the possible benefits of a CRRC rating.
In addition to the tradeshow booth, the CRRC also participated in a formal educational session during the Greenbuild program. Molly Trombley-McCann spoke on a panel with Jim Hoff of the Center for Environmental Innovation in Roofing and Steven Peck of Green Roofs for Healthy Cities. The focus of the panel included various rooftop sustainability strategies and ways to combine strategies in order to achieve maximum benefits. Around 130 people attended the session, and a number of attendees stopped by the booth afterward to request more information.
Overall, Greenbuild was a productive and well-attended conference for the CRRC!
Everyone is looking for ways to save money in today’s rough economy and the CRRC is pleased to provide you with a way to do just that. We have lowered our Class B Membership fee from $300 down to just $50. That’s over 80% off! This is a post-holiday sale you don’t want to miss. This fee modification was approved by the Board for adoption in 2010 to encourage Class B member participation in the CRRC. It was made in recognition that many Class B members are individuals, rather than companies, as are Class A members. Class B members include roofing contractors, architects, consultants, nonprofit organizations, educational institutions, government agencies, utilities, AITLs, TFs, and other interested individuals. For the full list please visit the CRRC Membership webpage: http://coolroofs.org/becomeamember.html.
Happy New Year to all CRRC members and staff! I hope everyone will have a bright and successful 2010. Looking back over 2009, everyone should have a sense of satisfaction from the long list of accomplishments and resolved issues. That list includes the addition of a color column to the Directory, progression for the CRRC-1 Standard within the ANSI standards process, release of the establishment of product compound ratings, and approval to add SRI to the Rated Products Directory (to be completed in 2010). In 2009, the CRRC also implemented multiple programmatic improvements including development of the multiple extended product label, acceptance of credit card payments, and creation of editable PDF applications. With the completion of the 5-year Strategic Plan we all can expect to continue our progress through 2010 and beyond.
Sincerely,
Rich Lee, CRRC Chairman
Here's the latest national and international news about cool roofs.
Color-changing Roof Tiles
A prototype tile developed by recent MIT graduates is designed to turn white in warm weather and dark in cold weather. This roofing tile would allow buildings to absorb heat in the winter and reflect heat in the summer, thereby reducing the cost of heating in the winter and cooling in the summer. The full article can be viewed here.

White Roofs, Cool Cities
Many have touted the ability of cool roofs to mitigate the urban heat island effect, but a new federal study released by the National Center for Atmospheric Research attempts to quantify this effect. The authors of this study claim that if every roof in a large city were converted to a cool roof, the average city would cool by 0.7 degrees. The full article can be viewed here.
Cool Roofs Catch On
Contractors have used cool roofing products for more than 20 years, but new tax credits and rebate programs have led to unprecedented growth in the industry. The EPA estimates that cool roofs are installed on 25% of commercial rooftops and 10% of residential rooftops. The full article can be viewed here.
Cool Roofs in Cool Climates?
Conservation Magazine touches on whether cool roofs are appropriate for all climate zones. A team reported in the Geophysical Research Letters that though whitening roofs around the world would cool off urban areas, it would also result in increasing heat loads in high-latitude regions. The full article can be viewed here.
