General Updates / Administrative
The CRRC Initial Test Results Report (Form F-2) is getting a new look! In response to recent changes in the CRRC Rating Program, we have updated Form F-2 to allow accurate reporting of test results for all current test methods. Changes include: a new section for reporting results from the Interim Tile Test Method, locations to record single-ply thickness measurements, and language clarification for the 5-Point Reflectance Test for rough-surfaced products. We hope the newly updated form will reduce confusion and expedite reporting for both the AITLs and CRRC staff.
We have also updated the Form F-3A, Addendum for Compound Rated Products, to include a section for rating Polymer products of differing geometries. The Addendum for Compound Rated Products form is to be submitted along with the Form F-3 Product Rating Application. This form removes the need for a comprehensive Letter of Explanation when submitting a compound rating. Form F-3A asks the applicant to provide the representative model name, representative model test results, and
the names of all other models that are to be covered by the compound rating. The form is designed for use with compound ratings for all eligible product types, including single-ply, shingle, modified bitumen, and molded polymer products.
If you have any questions about submitting an application, please contact Melissa Rissman at firstname.lastname@example.org or (510) 482-4420 x236.
During the June 23 in person Board meeting in Las Vegas, NV, the Board decided to reduce Color Family (CF) product fees where there were redundant fee charges. Specifically, the CRRC is merging the CF Representative Element fees into the CF Group fees, such that licensees will no longer be charged $50 to initially register a CF Representative Element, and will only be charged $215 to initially register a CF Group and Representative Element. CF Representative Element renewal fees will also be couched under the CF Group Fee. Questions regarding the change in fees can be directed to Melissa Rissman at email@example.com or 510.482.4420 x236.
The CRRC is contracting with Lawrence Berkeley National Laboratory (LBNL) to hold a CRRC Lab Training workshop at their site in Berkeley, California on Tuesday, August 24. The one-day course provides training on measuring the optical properties of roofing materials both in the laboratory environment and in the field.
The training covers the CRRC measurement standards listed below:
1. Solar reflectance measurements using:
•Spectrometer (ASTM E903)
•Pyranometer (ASTM E1918)
•Solar spectrum reflectometer (ASTM C1549 & CRRC-1 Test Method 1)
2. Thermal emittance with an emissometer (ASTM C-1371)
3. Coating thickness measurement using a caliper or other thickness gauge (based on ASTM D-1669)
The CRRC is reducing the cost of our Laboratory Training. In previous years the CRRC offered the training at $1,000 per participant. For the 2010 training the following fees will apply:
CRRC Members and Licensees — $350 per participant
Non-CRRC Members/Licensees — $500 per participant
The last day to register for the course is Monday, August 16, pending space availability.
Please email Jessica Clark at firstname.lastname@example.org if you are interested in attending the Lab Training.
Thank you to all CRRC members, licensees, and labs for participating in the 2010 renewals process. This year we introduced the option to pay online by credit card, as well as nominal late fees in order to encourage participants to pay on time. If your company has been terminated due to non-payment of 2010 dues, you may rejoin with a 3% reactivation fee. If you have any questions about the renewals process or suggestions for improvements, please contact Alexis Wong at email@example.com or 510.482.4420 x279.
As part of the CRRC’s quality assurance program, every year we select 10% of the licensed seller products on the Rated Products Directory and test them to ensure they meet their initially rated reflectance and emittance values. In 2009, 79 products were selected for testing, resulting in the following update:
• 53 products have passed
• 2 products have failed
• 9 products were suspended or terminated because no samples were
available or the product was no longer being manufactured
• 17 products are still being collected or tested at CRRC accredited
Once 2009 Random Testing is complete, we will send out the results to the Licensees whose products were tested. In the meantime, we have selected 92 new products for the 2010 round of Random Testing. Thank you for your cooperation in ensuring the credibility and accuracy of the CRRC Rating Program! If you have any questions about the random testing program, please contact Alexis Wong at firstname.lastname@example.org or 510.482.4420 x279.
June was a particularly busy month for CRRC staff, who attended two tradeshows in addition to holding the CRRC Board and Membership meetings. On June 10-12 CRRC staff hosted a booth at the AIA Expo 2010 in Miami, FL. This year there were over 800 exhibitors and more than 17,000 attendees at the expo. We had the opportunity to reach out to architects who were interested in learning more about cool roofing and encouraged them to take our cool roof continuing education course. The CRRC also staffed a booth at WSRCA’s Western Roofing Expo 2010 on June 20-22 in Las Vegas, NV. Staff had the opportunity to provide new promotional materials to current licensees as well as encourage manufacturers who are not yet licensees with CRRC to consider rating products with us. Tradeshows are a great opportunity for staff to meet CRRC licensees and members. If you happen to be at a tradeshow with us, please stop on by for a visit! Staff also encourage licensees and members who advertise in the tradeshow program booklets to include the CRRC logo with appropriate modifier in their advertisement. This is a great way to show that your product has been rated by a CRRC Accredited Testing Laboratory, or to demonstrate your organization’s leadership in the marketplace through participation with the CRRC! If you have any questions regarding proper CRRC logo use, please contact Jessica Clark at email@example.com or 510.482.4420 x227.
The Lawrence Berkeley National Laboratory’s Heat Island Group is currently working on a website for its Cool Communities project. This website will include a consumer-friendly search tool for cool roofing products that meet California code requirements. This new search tool will be directly linked to the CRRC’s Rated Product Directory. In order for the Cool Communities website to function to full capacity, displaying all possible product choices to consumers, the Heat Island Group has noted that all CRRC fields must be populated for each product. Currently, more than 26% of products are missing entries in search fields, mostly in the Color Category. Missing entries or incomplete product descriptions will reduce the possibility of your products being matched with customers’ search criteria. To create more comprehensive representations of your products, we encourage you to update data for your products by contacting Melissa Rissman at firstname.lastname@example.org or 510.482.4420 x236.
The CRRC Technical Committee held their last in-person meeting on June 9 in conjunction with the AIA Expo 2010 in Miami, FL. A conference call meeting was held Wednesday, August 4th. The next meeting will be an in person meeting in San Francisco, CA on Wednesday, September 29, 2010. If you are interested in participating in the next meeting, please contact Molly Trombley-McCann at email@example.com or 510.482.4420 x239.
Committee Officers and Roster
In June, Mr. Bill Kirn informed the CRRC Board that he would be stepping down as Technical Committee Chairman after 11 years of service. The CRRC would like to offer our profound thanks to Mr. Kirn for his dedication and support during the organization’s first decade. Mr. Kirn will continue to serve as a voting member of the Technical Committee, as Mr. Rick Olson of the Tile Roofing Institute has been elected as our new Technical Committee Chairman. Mr. Scott Kriner will serve as Vice Chairman. For the complete Technical Committee Voting Member roster, please visit the Technical Committee Roster.
High Profile Test Method Status Update
The High Profile Test Method (HPTM) Task Group has been working since 2008 to explore possible methods for measuring the solar reflectance of profiled roofing products. Currently, the only CRRC test method capable of accounting for profile is ASTM E1918, which does not provide consistent measurements across laboratories and requires the use of very large product samples. CRRC staff members are currently working with the Atlas Weathering Services Group to test the E1918 method with a powerful indoor solar simulator. The results of this study will be used to guide further research on high profile testing.
Template Method for Tile
The Board has approved an additional Interim Tile Test Method which can be used as an alternative to the modified CRRC-1 Test Method #1 solar reflectance test that is currently in place. The proposed test method is known as the Template Method. Instead of using randomly generated measurement locations as in the CRRC-1 TM#1 method, the Template method assigns a fixed set of 54 measurement locations across an array of nine tile samples.
If the standard error of the 54 measurements taken is less than 0.02 using the Template Method, then no further measurements are needed. The average of the 54 measurements is reported as the solar reflectance. If the standard error is above 0.02, then additional measurement locations must be generated randomly, as in the CRRC-1 TM#1 method, until the standard error for all measurements is below 0.02. At a future meeting, the Technical Committee will analyze the 0.02 threshold standard error value to determine if a more stringent threshold error value should be established.
Rough Surfaced Products
Roofing materials with a uniform color and a rough surface texture, such as a wood grain or slate pattern, may vary significantly in solar reflectance across the face of the product. In order to ensure consistent testing, all rough surfaced products must now be tested with the 5-point reflectance test to determine whether they should be treated as uniform or variegated products in further testing. Products determined to be uniform may be tested with either C1549 or E1918, while products determined to be variegated must be tested using CRRC-1 Test Method #1 (Monte Carlo method).
ASTM C1371 and High Thermal Resistance
ASTM C1371 is a method for measuring the thermal emittance of materials, and is the only thermal emittance test method currently approved by the CRRC for use in the Rating Program. The method was designed for use with coatings and films, and may produce inconsistent values for materials with high thermal resistance, such as tile. The Transient Method, developed by Devices & Services, who produce the emissometer device, is designed to improve the consistency of C1371 measurements when testing materials with high thermal resistance. CRRC staff are organizing a Round Robin test of the Transient Method in order to determine its repeatability and explore the possibility of adding it to the CRRC Rating Program as an approved test method. Results of the Round Robin are expected to be complete by late 2010.
Sample Requirements for Variegated Products
In June the Technical Committee approved changes to the
CRRC-1 Program Manual clarifying sample requirements for variegated products that are neither shingle nor modified bitumen. The language states that the manufacturer must submit nine samples, four each from two separate production batches and an additional one from either production batch. Each sample shall have a minimum area of at least 40 square inches (102 square centimeters).
Accompanying the memorandum on its new cool roof policy, the DOE also released its Guidelines for Selecting Cool Roofs. This document was prepared as part of the DOE’s Building Technologies Program and is designed to provide technical assistance for federal agencies and commercial builders interested in installing cool roofs. The document includes an introduction to types of cool roofs, as well as a thorough discussion of cost-benefit analysis, selection, application, and considerations to take into account when installing cool roofs. The document can be viewed here. Look for the section on product labeling and the CRRC on page four!
The Heat Island Group at Lawrence Berkeley National Laboratory recently released two articles about the measurement of solar reflectance. One article explores how solar reflectance varies with surface orientation and solar position, and found that clear sky air mass 1 global horizontal (AM1GH) solar reflectance is a preferred quantity for estimating solar heat gain. In the second article, the study demonstrated that AM1GH solar reflectance can be accurately measured with a pyranometer, a solar spectrophotometer, or an updated edition of the Solar Spectrum Reflectometer (version 6).
The study was published in two parts in the journal Solar Energy:
• Measuring solar reflectance — Part I: Defining a metric that accurately predicts solar heat gain
– By: Ronnen Levinson, Hashem Akbari, and Paul Berdahl
• Measuring solar reflectance — Part II: Review of practical methods
– By: Ronnen Levinson, Hashem Akbari, and Paul Berdahl
If you would like to obtain these articles but are unable to download them from the journal's website, please contact Jessica Clark at firstname.lastname@example.org or (510) 482-4420 x227.
Ratings, Codes and Programs
The EPA’s ENERGY STAR program continues to move forward with designing a verification system for each of its qualified product programs. The EPA intends to finalize the verification requirements by late summer 2010 and implement the requirements by the end of the year. To stay current with their process, please visit their Enhanced Testing and Verification webpage: http://www.energystar.gov/index.cfm?c=partners.enhanced_test_verification
The CRRC has reached out to the EPA to work with them on developing the ENERGY STAR Qualified Roof program, meeting with them on several occasions. In addition, we have submitted comments on both the Lab and Certification Body requirements. If you have any questions about the CRRC’s involvement with the EPA verification process, please contact Sherry Hao at email@example.com or 510.482.4420 x256.
In May, Philadelphia became the latest city to adopt a cool roof policy when Mayor Michael A. Nutter signed the Cool Roof law. The legislation states that all new commercial and residential buildings with roofs that have low or no slope will require a cool roof. This is anticipated to largely affect the construction of row houses and commercial buildings. The law is part of the city’s attempt to become the greenest city in America, and will contribute to the city’s Greenworks Philadelphia initiative to reduce energy consumption by 10% and retrofit 15% of all housing stock by 2015. Articles containing more information on the law, as well as Philadelphia’s accompanying “Coolest Block” contest can be found at Builder Online and USA Today’s website.
In July, the Secretary of Energy, Steven Chu, issued a memorandum requiring that all roof replacements and new construction of Department of Energy (DOE) buildings include a cool roof. Additionally, all new roofs must have a thermal resistance of at least R-30. Chu writes that this action is to help mitigate the energy consumption of the federal government, which is the largest consumer of energy in the nation. The initiative is part of President Obama’s Executive Order on Sustainability, which aims to lower the government’s greenhouse gas emissions by 28% by 2020. Chu also urged other federal agencies to adopt a similar policy on cool roofs, stating that, “By demonstrating the benefits of cool roofs on our facilities, the federal government can lead the nation toward more sustainable building practices, while reducing the federal carbon footprint and saving money for taxpayers.” An article on the initiative can be read here.
New Yorkers are on a mission to install one million square feet of cool roofing by October 2010. An initiative of the NYC Service, the NYC Department of Buildings and the Community Environmental Center, the NYC °Cool Roofs Program will reduce the city’s annual energy costs by $136 million. The program’s cool roof goals include:
1. Coat the rooftops of city agency buildings
2. Work with non-profit organizations to coat their rooftops
3. Provide resources to encourage homeowners to coat their own roofs
More information on the NYC °Cool Roofs program and how to get involved can be found here.

The CRRC held its annual Membership meeting on June 24th in Las Vegas, Nevada. The presentations (available at http://www.coolroofs.org/events.html, or by clicking on individual headings below) included:
CRRC Administrative Update
The administrative update covered board and staff transitions, organizational growth over the past year, marketing and outreach efforts (tradeshows, articles, continuing education course, newsletters and presentations), and updates on the rating program, random testing, and the strategic plan.
CRRC Technical Program Update
The technical program update reviewed new Technical Committee voting and attendance policies, CRRC-1 rating program changes, and ongoing research studies.
CRRC-1 ANSI Standard Update
In late June the CRRC-1 Standard was submitted to ANSI to become an American National Standard and is currently awaiting final approval. The presentation also included background information on the ANSI effort and future actions.
Codes & Programs Update
This section provided an update on current codes and programs with cool roofing sections, focusing on ASHRAE 90.1 & addendum f, the International Energy Conservation Code (IECC), the International Green Construction Code (IgCC), the California Green Building Standards Code, California Title 24, Collaborative for High Performance Schools, and the City of Philadelphia’s new cool roof bill. Once the CRRC-1 Standard is recognized by ANSI, code change proposals will be sent to ASHRAE 90.1, 90.2, and 189.1, as well as IECC, IgCC, and IRC-Energy.
International Green Construction Code
Kermit Robinson (Senior Technical Staff, International Code Council) provided an overview of the International Green Construction Code (IgCC), which focuses on commercial properties. The IgCC is not intended to replace voluntary programs such as LEED, since it presents a set of mandatory requirements. The code is written as model code for jurisdictions to adopt and alter its language as necessary. The urban heat island effect and cool roofs are addressed in Chapter 4. The roof coverings section of this chapter currently references CRRC-1, although there have been proposals submitted to remove the CRRC-1 Standard.
Building Codes in Australia
Tony Tanner (Executive Director, Roofing Tile Association of Australia) gave a presentation on roofing codes in Australia and the role and history of the Roofing Tile Association of Australia. He also shared some data on the thermal performance of different roofing materials.
Jim Hoff (Research Director, Center for Environmental Innovation in Roofing (CEIR)) gave a presentation on RoofPoint, a new rating program initiated by CEIR to rate new roofs as well as roofing retrofits. RoofPoint is designed to increase the visibility of roofing and emphasize the importance of re-roofing, while rewarding the installation of durable, environmentally responsive, and energy efficient roofing systems.
EPA ENERGY STAR
Tom McKay (Product Manager, PPG, CRRC Board Member FY2007-2010) provided an update on the proposed ENERGY STAR verification program, which the EPA is aiming to have in place by the end of 2010. The CRRC is working with the EPA in an effort to have them adopt the CRRC program for rating ENERGY STAR Qualified Roofing Products.
For more details, please see the presentation linked above or visit http://www.energystar.gov/testingandverification. The EPA has periodically released program criteria documents, followed by an open public comment period. These comment periods present opportunities to assist the EPA in developing their verification process. The CRRC encourages our licensees and members to communicate your industry and organization needs and perspectives with the EPA.
The CRRC added two Board meeting conference calls in May to the yearly schedule, in order to handle the influx of issues flooding the organization this year. The next Board conference call is scheduled for September, and the following in-person Board meeting is scheduled for November 19th. If you would like to attend either of these meetings, please contact Sherry Hao at firstname.lastname@example.org or 510.482.4420 x256.
May 20th & 26th Board Meetings
The two May Board conference call meetings resulted in the following decision:
The Board voted to approve the ANSI CRRC-1 Standard, following the Consensus Body vote for Consensus Achievement. The CRRC submitted the standard to ANSI for their review on June 22, 2010.
June 23rd Board Meeting
On June 23, 2010 the Board held an in-person meeting in Las Vegas, NV, in conjunction with the Western States Roofing Contractors Association Convention. The beginning of the meeting covered the 2010 Board Election and selection of Board Officer positions, the results of which can be seen above. A full list of the Board members can be seen
here. The agenda was packed with discussion items, resulting in the following key decisions:
Committee Voting and Alternate Members
The Board approved Rick Olson as the Technical Committee Chair, and Scott Kriner as the Vice Chair. 15 individuals were approved as the FY2010-2011 voting and alternate Technical Committee members. The Board carefully reviews the roster to ensure diversity and balance on the Committee. The full roster can be viewed here.
The Board approved several program updates, as listed:
||An updated CRRC Test Results Report form, which can be
||All rough surfaced products must be tested with the 5-point reflectance test to determine if the CRRC-1 Test Method #1 is necessary for measuring the solar reflectance of the product.
||Sample size requirements for variegated non-shingle or non-modified bitumen products were approved as:
These samples shall be grouped into three sets:|
1. Three (3) samples from one Batch;
2. Three (3) samples from a second Batch;
3. Three (3) samples for which each of the two Batches shall be represented.
This results in a total of four samples from one batch and five from the other.
Advisory note: Tile is tested with the Interim Tile Test Method which specifies sample size requirements.
The set of all samples to be tested under CRRC-1 Test Method #1 shall have an aggregate area of at least 360 square inches (914.4 square centimeters). For non-shingle or modified bitumen products, the area of each sample must be at least 40 square inches (102 square centimeters).
||Language was added to the CRRC-1 Program Manual regarding compound ratings for polymer products of different geometries. The language can be viewed in section 3.5 of the Program Manual here
||Approval of the tile template method, to be used along with the current Interim Tile Test Method (CRRC-1 Test Method #1 with a standard error allowance of 0.02). The Board agreed with the Technical Committee recommendation that should the Template Method not yield a standard error of 0.02, the AITL must then employ the original Interim Tile Test Method (CRRC-1 TM#1).
||The Board did NOT approve allowing a Licensed Seller (LS) to reference a licensed Other Manufacturer (OM) that already references an OM rated product. Please note, this means that OM rated products may only be referenced by LSs who have a direct relationship with the OM.
||Reduction of Color Family (CF) product fees where there were redundant fee charges. Specifically the CRRC is merging the CF Representative Element fees into the CF Group fees, such that licensees will no longer be charged $50 to initially register a CF Representative Element, and will only be charged $215 to initially register a CF Group and Representative Element. CF Representative Element renewal fees will also be couched under the CF Group Fee.
||Removal of outdated ISO 25 from the AITL accreditation requirements. All CRRC accredited testing laboratories must be ISO 17025.
||A Board Class A Constitution Task Force was approved and is comprised of the following individuals:
Mike Ennis — SPRI
Payam Bozorgchami — CEC
Marty Hastings — Dura Coat
Joe Mellott — Garland
Jim Baker, Task Leader — ARMA
Rick Olson — TRI
Jim Leonard — ER Systems
Scott Kriner — MCA
Technical Study Updates
||The Board approved conducting a Round Robin study on the C1371 Transient Method (a variation that may produce accurate thermal emittance measurements for high thermal resistance products).
||The Board approved conducting an indoor light study for E1918 with Atlas Weathering Services Group.
