Update: CRRC-1 Standard Review for ANSI-
Second Public Comment Period OPEN on April 13

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 Second Public Review will open Monday, April 13, 2009, and will allow all members of the public to submit comments on the significant revisions from the First Public Review. Therefore only comments in reference to the significant changes from the First Public Review will be accepted. Information about the Second Public Review and how to submit comments is available on the website at www.coolroofs.org.

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.

Board Elections

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.

Color Added to the Product Directory

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.

Upcoming CRRC Laboratory Training Course

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:
1. Solar reflectance measurements using:

Spectrometer (ASTM E 903)
Pyranometer (ASTM E-1918 and E1918A)
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 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.

Technical Update

Technical Committee Meeting Recap

The CRRC Technical Committee met by phone on February 24, 2009. Key updates from the meeting include:

Reflectometer Study
The CRRC has received samples from manufacturers and will be sending them to Oak Ridge National Laboratory and Devices & Services for testing to examine how the updated version of the reflectometer may impact product ratings.

High Profile Test Method Task Group
The Task Group is pursuing a number of methods to test profiled products, including modifications to the C1549 test method and an analytical model.

Research Opportunity: Extended Product Aging
The Technical Committee discussed an idea to conduct a study on the effect of extended aging on cool roofing products. With manufacturer permission, some aged samples could be left on the test farm for 5 or more years and periodically tested. This would have no impact on ratings, but would provide valuable data on the long-term performance of cool roofing.

Alternate Voting Members
The Technical Committee Alternates process is as follows: At the annual meeting when the Board assigns the Technical Committee voting members, they will also assign a permanent alternate for each voting member with similar interests to help ensure a quorum at Technical Committee meetings.

Upcoming Technical Meeting

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.

ENERGY STAR Accepts CRRC Color Families

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.

The CRRC’s Color Family Program was developed with the Cool Metal Roofing Coalition and allows manufacturers to group metal products (and their coatings) by color space. Each group must have a Representative Element, which is tested for both initial and aged reflectance and emittance. All other products in the group, called Additional Elements, only require initial testing. All Color Family products are listed on the CRRC directory using the default for the Color Family Group (from Table 1 in CRRC-1 Program Manual). For more information on the Color Family Program, including Table 1, please see Procedure 3: Color Family Program.

DOE Ruling: More Stringent Building Energy Standards

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 2004 standard has the same cool roof requirement that allows a reduced minimum requirement for insulation in climate zones 1, 2 or 3 if a cool roof is installed with a minimum solar reflectance of 0.70 and a minimum thermal emittance of 0.75. The CRRC is referenced in the standard.

ASHRAE is continuing to improve building energy performance standards, and is currently working on a 90.1- 2010 version that will save 30 percent energy compared to 90.1-2004 standards. Their goal is to have net-zero buildings by 2015.

ISO Building Environment Design

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.

ASHRAE Standard 90.1 (2007 edition), Energy Standard for Buildings Except Low-Rise Residential Buildings, section 5.5.3.1.1, still defines a cool roof as having a minimum solar reflectance of 0.70 and a minimum thermal emittance of 0.75, but the new version also allows a minimum Solar Reflective Index (SRI) of 82. The new standard for 90.1 increases the applicable climate zones areas to 1 to 5 (the previous version was from 1 to 3). The section also states that values for solar reflectance and thermal emittance shall be determined by a laboratory accredited by a nationally recognized accreditation organization, citing the CRRC as an example.

ASHRAE Standard 90.2 (2007 edition), Energy Efficient Design of Low-Rise Residential Buildings, section 5.6, defines a cool roof in climate zones 1, 2, and 3 as having a minimum solar reflectance of 0.65 and a minimum thermal emittance of 0.75 or a minimum SRI of 75. “High Albedo Roofs” are a prescriptive requirement and if installed allow the residential building to have a lower R-value and a higher U-value for insulation. As with Standard 90.1, the CRRC is referenced as a nationally recognized accreditation organization in Standard 90.2.

Report on Green Building Impacts

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.

The report states that LEED buildings use approximately a quarter less energy than non-LEED buildings, have to date prevented the burning of 1.3 million tons of coal, and by 2015 will have prevented the burning of 26 million tons of coal. In terms of water savings, existing LEED buildings have thus far saved 9.5 billion gallons and by 2015 will have saved 133 billion gallons. The report also estimates that in order to meet an 80% reduction of greenhouse gases by 2050, existing commercial buildings must reduce their carbon dioxide emissions by 1.6% each year.

ASHRAE Standard 189.1 Committee is Reconstituted

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.

Dr. Hashem Akbari’s Work featured in Press

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.
