Annual Renewals 2010: Update

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.

Please note that if your company has not completed their renewals by January 1, 2010, your renewal fees are now overdue. To encourage on-time payments and to create an equitable process for licensees who do pay before the deadline, the CRRC is implementing a nominal late fee charge. The late fee charge is 1% of your total payment per month; therefore, it will accrue by 1% each additional month the payment is late. If your company is currently processing the payment, please let us know and we will work with you to try to avoid this late fee. The late fee structure is as follows:

     
Payment received by
Late Fee
January 1, 2010
None
February 1, 2010
1% of total payment
March 1, 2010
2% of total payment
April 1, 2010
Termination with a 3% of total payment
reactivation fee


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.

Please log onto http://renewals.coolroofs.org if you have not done so already. If you are unsure what your password is or if you have any questions related to the online Renewals system, please do not hesitate to contact Alexis at Alexis@coolroofs.org or (510) 482-4420 ext 279.

We welcome any feedback or suggestions as it will help us improve the system for next year. Please send us your comments regarding your experience with the online process.

Increasing Test Farm Product Placement Frequency

The 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:
• Brand Name
• Model Name/Number

Brand Name
There are no hard and fast rules, but some guidelines for choosing what to enter for a Brand name may include:
•The name of the product line or series
•Your company name

Model Name/Number Some guidelines for choosing what to enter for a Model Name/Number may include:
• Distinctive color names like “Pale Peach”
• The product series name plus a color
• A literal product description like “Permax 108 White w/RTC White Granules”
• A model number

Initial Test Results Report (F-2) is another CRRC form where the Brand and Model Names are important. Please make sure that you designate a distinct Brand or Model Name, allowing the product to be easily distinguished when it is returned from its three year weathering period on the test farm. If you are submitting projects with similar model and brand names, such that it is difficult to differentiate between products, please add the product SKU number for identification purposes. The product SKU number may help the AITL/TF/CRRC staff differentiate between similarly named products.

Giving thorough consideration to the Brand Name and Model Name of your products will give consistency to your paperwork as it progresses through the testing and weathering process. Mix-ups can happen when product names are too similar or lack description, resulting in time and money wasted.

Choosing appropriate Brand and Model names can also act as a boon to your marketing when an architect, specifier or homeowner searches the CRRC Product Directory for your product. If they enter a unique Brand Name and Model Name in their search, only your product record should appear. Consistency pays! If you have any questions about applications and Brand and Model Names, contact Melissa at Melissa@coolroofs.org or (510) 482-4420 ext 236.

Clarification of Random Testing Program
Requirements

CRRC staff has received some inquiries about the random testing program and we would like to take this opportunity to clear up some confusion. We do not require product samples to be taken from existing roofs. Our procedure is to use the list of contractors and distributors provided by the Licensed Seller to obtain product samples. Samples may be leftover from previous projects or from currently available stock. These contractors and distributors will be listed on form F-9 (http://coolroofs.org/alldocs.html#f9) when a Licensed Seller applies for new product applications. If you have any questions about the Random Testing program, please contact Alexis at Alexis@coolroofs.org or (510) 482-4420 ext 279.

Color Family Language Clarification

In order to help licensees understand the color family program for metal products and their factory-applied coatings, the CRRC has recently updated the document How Do I Get a Color Family Rating Program? The document includes more detailed definitions and descriptions of the Color Family product application process. Please contact the CRRC staff at (866) 465-2523 if you have any questions.

Technical Update

Technical Committee Meeting Update

The Technical Committee met in person September 30, 2009. Highlights include:

Technical Committee Attendance Policy:
The Committee voted to recommend that the Board approve a new attendance policy for Technical Committee voting members. The recommended policy stipulates that if a voting member misses three meetings in a row they are removed from the voting member roster and a replacement is chosen by the Board. If a voting member leaves a meeting before the last scheduled voting item, they are considered to be absent. This does not apply to voting items that arise during new business and are not listed on the agenda. If a voting member arranges for their alternate to be present in their place, they are not considered absent. The Board of Directors approved this recommendation November 10, 2009.

Compound Ratings: Shingles, Modified Bitumen, and Cap Sheet Products:
The Technical Committee recommended that the Board approve specific language allowing certain types of shingles and modified bitumen products to use compound ratings. The language would allow a single rating for all products that share the same surface formulation (including granule composition and coating). This would allow a group of shingles with the same color blend but different styles and weights (three tab, architectural, etc.) to use a single rating, requiring that only a single representative product be tested. Similarly, modified bitumen cap sheets with the same granules and coating coverage rate but different non-exposed system components would be able to use a single rating. The Board of Directors approved this recommendation with some changes at the November 2009 and January 2010 meetings. For more information please see the Board of Directors update below.

Coating Thickness and Coverage Rate:
During the discussion of compound ratings, the issue of measuring coating thickness was raised. The Committee proposed that coating thickness, which cannot be easily measured over a granular surface, be replaced with coverage rate in either pounds or gallons per unit area. Staff drafted a definition of coverage rate for the CRRC-1 Program Manual and brought it before the Board at the November Board meeting. The Board approved the definition as part of the compound rating language exhibit.

Stand Alone Granule Ratings:
In response to a licensee request, the Committee proposed a policy for rating loose granules without adhesive or backing material. The proposed policy stipulates that the samples be initially tested at the AITL, then disassembled, shipped and reassembled at the weathering farms, and, upon three year aging, tested onsite at the weathering farms. This would require an AITL to travel to each of the three weathering sites to take measurements once aging is complete. The intent of the proposal is to allow the samples to be prepared in the same manner as they would be applied to a roof, with no risk of the product shifting during shipping. The proposal will be considered at a future Board meeting.

Solar Reflectance Index (SRI) and the CRRC Directory:
Prompted by a licensee request, the Committee discussed the possibility of adding SRI values to the online Rated Products Directory. The Committee considered the number of codes and rating programs now using SRI as a cool roof metric (including LEED and the updated 2008 California Title 24 Building Efficiency Standards), and the need for an authoritative and credible value for SRI. The final Technical Committee recommendation to the Board was to include two new columns on the CRRC Product Directory, one for initial SRI and one for aged SRI, both using medium wind speed. Each product would include a note stating which test methods were used to obtain the underlying solar reflectance and thermal emittance numbers, in recognition that SRI values may vary according to the test method applied to measure reflectance and emittance. Where aged values are not yet available, the aged SRI will be listed as pending. The Board of Directors approved this recommendation November 10, 2009.

LBNL & ORNL Accelerated Aging:
Mr. Levinson announced Lawrence Berkeley National Laboratory, in partnership with Oak Ridge National Laboratory, is launching a study to examine lab processes for accelerated aging of roofing materials. The project was to begin October 1, 2009 and continue for two years. Mr. Levinson encouraged manufacturers to assist in the study and send product samples. For more information please contact rmlevinson@lbl.gov.

E1918A Round Robin Update:
The recently completed E1918A Round Robin showed a considerable degree of variation in results between labs. The Committee proposed that the CRRC conduct a ruggedness test on E1918, varying every possible factor and quantifying the degree to which each factor impacts the test results. The Committee suggested that a task group of interested CRRC participants convene by conference call to discuss the details of the robustness study. The High Profile task group will be combined with the E1918 Study task group. The proposed study was accepted by the Board at the November 2009 meeting.

CRRC-1 ANSI Standard Update

The Consensus Body is in the process of reviewing and responding to comments for the ANSI Second Public Comment Period regarding the ANSI accreditation of the CRRC-1 Manual. Once this is complete, there will be a Third Public Comment Period to address any substantive changes. 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 the end of 2009.

Informative documents are available for review at
http://coolroofs.org/StandardReview.html#secondpcp

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.

Ratings, Codes and Programs

California Green Building Standards Code
(CALGreen)

On January 12, 2010, the California Building Standards Commission unanimously adopted the first statewide mandatory Green Buildings Standards Code under the name CALGreen. The standard will take effect January 2011. These regulations are intended to reduce statewide greenhouse gas emissions, energy consumption, and water use. Compliance will be enforced by government agencies, and will cover buildings of all occupancy types. It will be integrated into existing California building codes and regulations.

State jurisdictions have the option to adopt Tier 1 or Tier 2 of the green code, if they want to be considered a California green community. Tier 1 meets the Savings by Design, Healthcare Modeling Procedures requirements. Tier 2 exceeds the Savings By Design requirements by a minimum of 15%. Both tiers specify cool roof requirements.

The CALGreen Code cool roofing specifications can be viewed in section A4.106.5, starting on page 67, and under the Heat Island effect: Cool Roof (section A5.106.11.2), page 104. Exceptions are provided for roof constructions that have a thermal mass over the roof membrane with a weight of at least 25 lb/ft2 .

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.

You can learn more from the California Building Standards Commission website at http://www.bsc.ca.gov/default.htm.

International Green Construction Code

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.

ASHRAE Proposed Standard 189.1
Approved for Publication

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 Standard 90.1 Update 2010

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.

California Title 24 Standards 2008
Updates In Effect

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/.

European Cool Roof Council

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/.

Building Codes Assistance Project

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.

Membership and Outreach

Board of Directors Meeting Recap

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.

Changes to the Technical Committee
Structure

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.

Greenbuild Recap

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!

Changes in Class B Membership Fees

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.
