Licensees who have not contacted the CRRC regarding its annual renewals or have not logged onto the CRRC online database, have been subsequently suspended and their products have been removed from the online directory. If you have received notice that your company has been suspended but you would like to renew, please contact Kathleen Phu at Kathleen@coolroofs.org.
In accordance with the CRRC’s procedures for consensus review, the CRRC-1 Standard was balloted by the Consensus Body and completed its first Public Comment Period on December 9, 2008. The Standards Committee responded to all comments at the end of January 2009. Commenters were then allowed to respond with continuing objections.
The CRRC Board of Directors has three positions opening up this year, two Class A member positions and one Class B member position. Board member candidates have been nominated by the CRRC membership and voting will commence on April 20 and end on May 20, 2009. Election results will be announced to all CRRC members by the end of May. The newly elected Board of Directors will convene and vote on officer positions at the June 16th Board meeting. If you have any questions about the CRRC Election process, please contact Julie@coolroofs.org.
Thank you to the licensees who submitted their CRRC-rated product color information! In April the online product directory will be updated to include a field for color and will allow users to search by color. If you are interested in having the color of your products listed and searchable on the directory, and have not yet done so, please contact Julie@coolroofs.org for a product list and color selections.
The CRRC is contracting with Lawrence Berkeley National Laboratory (LBNL) to hold a CRRC Lab Training workshop at their site in Berkeley, California. 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:
Spectrometer (ASTM E 903)
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 Lab Training will also cover one new procedure this year: the new interim testing requirements for tile roofing products.
Please email Sherry@coolroofs.org if you are interested in attending the Lab Training. The date of the class will be determined by the availability of participants.
The CRRC Technical Committee met by phone on February 24, 2009. Key updates from the meeting include:
The next meeting will be in-person on April 29th in Washington, DC, in conjunction with the RCIF Conference. If you are interested in attending the Technical Meeting, please register for the meeting here. Technical meeting fees are $100 if purchased by April 10th and $150 if purchased after April 10th. Meals and a meeting packet will be included.
Ratings, Codes and Programs
A reminder that the new 2008 Title 24 standards will affect projects whose building permit applications are submitted on or after August 1, 2009.
Tom McKay, CRRC Board Member and Product Manager for PPG, explained the CRRC’s Color Family Program to ENERGY STAR, who agreed to allow manufacturers to rate their Color Family Additional Elements using only the initial tested data, provided that the data for the group’s Representative Element is also submitted. The aged value will be listed on the ENERGY STAR list as the default value for the Color Family Group.
In January 2009, the United States Department of Energy (DOE) made a ruling under the Federal Energy Policy Act that all states must certify that their building codes meet the requirements in ANSI/ASHRAE/IESNA’s 90.1-2004 Energy Standard for Buildings Except Low Rise Residential Buildings. The Act requires all states to certify that they have state energy codes in place that are at least as stringent as 90.1-2004 standards. Standard 90.1-1999 was previously referenced, but the DOE determined that the 2004 version reduces commercial building energy consumption 14 percent compared to the earlier version.
The International Organization for Standardization (ISO) recently released a new standard called Building Environment Design, to be used as a guideline to improve the energy efficiency of new buildings (ISO 23045:2008). The standard provides specific design guidelines to help the building sector increase building energy efficiency, and thereby reduce contributions to greenhouse gas emissions and global climate change. ISO 23045:2008 applies to new buildings and is also applicable to systems for heating, cooling, lighting, domestic hot water, service water heating, ventilation and related controls. While cool roofs are not mentioned in the body of the standard, reference is made to ASHRAE Standards 90.1 and 90.2, both of which contain the following cool roof provisions.
In the first-ever comprehensive assessment that encompasses land, water, material and indoor environmental impacts for LEED-rated buildings, GreenerBuildings.com has published a report quantifying the saving impacts of green buildings. This report provides further support in promoting green buildings and cool roofs for future savings and meeting greenhouse gas emission reduction targets.
In October 2008, the committee that is designing the first national building code standard on high-performance green buildings suspended their work. In late January 2009, the reconstituted members convened at the Winter Conference of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and created a work plan for draft Standard 189.1 for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings. The standard aims to set “a rigorous environmental baseline” and is expected to be published in January 2010. For more information, see: http://www.bcap-energy.org/node/331.
Membership and Outreach
The Second International Conference on Countermeasures to Urban Heat Islands (ICCUHI) will be held on September 21- 23, 2009 in Berkeley, California. The conference is devoted to the science, engineering, and public policies that help relieve the excess heat and air pollution in hot cities. It will emphasize cool materials, including roofs, as an important counter measure to the urban heat island effect. The Conference Chairman, Dr. Hashem Akbari of LBNL, leads an organizing committee with strong representation from Asia and Europe, as well as the United States and Canada.
The CRRC website (www.coolroofs.org) has been a popular site to visit. In total, the website has received almost 9,000 visits since the beginning of the year, averaging 113 per day, as tracked by Google Analytics. Most visitors are from the US (86%), followed distantly by Canada (3%), India (1%), and Mexico (1%). Data from January 2009 through mid-March showed 1,257 visits from abroad, though some base level of visits originate from automated tracking systems and search engines.
Within the US, most site visitors of known origin (unknown is 32%) are from California (30%), followed by Texas (8%), Florida (6%), and New York (5%). Both maps show visitors from the beginning of the year through mid-March.
Pacific Gas and Electric Company (PG&E) is offering multiple workshops regarding cool roofs this spring. If you are interested in learning more on rebates and code requirement updates in the PG&E territory, we encourage you to attend one of the following spring classes.
Dr. Hashem Akbari from Lawrence Berkeley National Laboratory has received a lot of positive press recently. Dr. Akbari and his work on cool roofs have been featured in several newspapers and on ABC, including:
All three press pieces discuss how worldwide implementation of cool roofing materials can help mitigate the symptoms of climate change based on an LBNL study that 100 square feet of black rooftop converted to white could offset about 1 ton of carbon dioxide.
Spring 2009 Issue
I hope that all members despite the economic downturn have had a productive first quarter and can see the light at the end of the tunnel coming in the later portion of the year. During this time when all business activities are being closely monitored for benefit and returns, I am pleased that everyone continues to see the advantage to continuing to participate in organizations such as the CRRC. The staff is working hard to bring a highly educational and beneficial itinerary to the membership meeting this June. I look forward to seeing members in Reno to taking advantage of their membership benefits.
Julie Guyenet comes to the CRRC with a diverse background of both environmental science and management and strong interests in sustainable development and green building. She has a background in environmental consulting and is excited (and delighted) to become further involved in the roofing aspect of green building.
CRRC at the International Roofing Expo (IRE) and Roofing Consultants Institute (RCI) Tradeshow
Staff attended the annual International Roofing Expo February 3rd through 5th in Las Vegas, NV and the Roofing Consultants Institute Tradeshow March 14th and 15th in Dallas, TX. Both tradeshows provided CRRC staff an opportunity to interact with roofing professionals while staffing the CRRC booth, as well as on the tradeshow floor.
Cool Roofs in the News
• The January/February edition of Eco-Structure Magazine featured an article by Tom Hutchinson, titled “Challenging What’s Cool: Is the Exponential Growth of Cool Roofing an Impending Catastrophe?” Mr. Hutchinson’s article points out problems with roof construction that lead to roof failures, yet attributes the problems to the use of cool roofing materials, rather than improper installation.
We agree with Mr. Hutchinson that roofs must be considered as a whole system but would argue that cool surfacing materials are an important component of an energy-efficient roof. The use of cool roofing does not negate the need for appropriate roof system design considerations, but cool roofs can have a positive impact on energy savings and provide other environmental benefits, such as a reduction in the urban heat island effect, when properly specified and installed.
The letter will be published in an upcoming issue of EcoStructure. Read the full version of the CRRC’s letter here.
• CRRC’s Cool Roof Article Published in Poland: In July 2008, CRRC’s published an article in the Journal of Green Building. In August 2008, one of the CRRC’s Members and Licensed Sellers was contacted by a customer in Poland who had read the article and wanted to have it translated for a Polish publication. The article was translated and published in February 2009.
• The March issue of Building Operating Management contains an article titled “Setting the Standard: trying to understand the mish-mash of cool roofing code and rebate requirements can leave facility executives hot under the collar” by contributing Editor Loren Snyder. The article cites CRRC’s Technical Chairman Bill Kirn, Secretary Greg Crawford and ex-officio Board member Hashem Akbari, and provides an overview of existing codes and programs for cool roofs.
