Update of ANSI/CRRC S100
First Public Comment Period: June 14, 2019 – July 29, 2019
The 45-day public comment period on the proposed changes to the CRRC S100 standard closed on July 29, 2019.
Second Public Comment Period: September 27, 2019 - November 11, 2019
This 45-day public comment period on the proposed substantive changes to the standard approved by the Consensus Body after the close of the first public comment period starts on September 27, 2019 and closes on November 11, 2019. All members of the public have the opportunity to review the proposed revisions and submit comments. Please note that only the revisions shown as redline in the draft S100 standard linked below are open for comment.
Comments must be submitted to the CRRC in writing (either by email or mail) and must be received by the end of the designated public comment period in order to be considered. Comments must be submitted using the CRRC public comment form. Submission instructions are provided on the form.
All public comments must be received by 11:59 PM Pacific on November 11, 2019.

Consensus Body Roster
The Consensus Body is responsible for evaluating the proposed changes and public comments on ANSI/CRRC S100. The group was officially established on February 4, 2019.
Consensus Body Interest Categories:
- Users: Individuals who represent entities that use the CRRC Product Rating Program or ANSI/CRRC S100 to specify products either for installation, for regulatory purposes or for a voluntary program. This category includes building owners, facilities personnel, government agencies that use the CRRC Product Rating Program or ANSI/CRRC S100 as the basis for regulation, organizations that have green building certification programs or rebate programs, specifiers, consultants, contractors, and building inspectors. This category also includes organizations that provide testing and weathering services for CRRC Licensees (e.g., Accredited Independent Testing Laboratories and Approved Test Farms).
- Producers: Individuals that represent entities that produce or sell products that may be rated by the CRRC. This category includes companies that produce or sell roofing materials and organizations that represent companies producing and selling roofing materials (e.g., industry or trade associations).
- General Interest: Individuals that represent entities that do not use the CRRC Product Rating Program or ANSI/CRRC S100 directly and do not produce or sell roofing materials. This category includes independent research organizations, government agencies with an interest in energy or environmental issues (but do not establish or adopt regulations pertaining to cool roofs), non-profit organizations, and other organizations that do not directly profit from roofing product sales but have a general interest in cool roofing, energy-efficiency, sustainability, green building practices, and other related issues.

The CRRC became an accredited standards developer for the American National Standards Institute (ANSI) in 2007. After a three-year process, the first edition of ANSI/CRRC S100 - Standard Test Methods for Determining Radiative Properties of Materials (formerly CRRC-1 Standard) was approved on November 16, 2010.
ANSI's Essential Requirements and CRRC's procedures specify that the process for standards development must be a collaborative, balanced, and consensus-based approval process. As such, every few years the standard must go through a public review process. As part of this process, consensus must be reached by representatives from materially-affected and interested parties. ANSI/CRRC S100 (2016) was developed with input from the public and the CRRC Consensus Body, a balanced group representing diverse interests, ensuring that all aspects of the standard are considered.
ANSI/CRRC S100 covers test specimen preparation and test methods for measuring the initial and aged radiative properties of roofing products. ANSI/CRRC S100 is referenced by building codes and rating programs worldwide in order to measure the initial and aged solar reflectance and thermal emittance of roofing products.
Frequently Asked Questions
What is ANSI/CRRC S100?
ANSI/CRRC S100 (formerly CRRC-1 Standard) was developed as a consensus-based standard to provide a consistent reference in energy and building codes regarding measuring the radiative performance of roofing performance. ANSI/CRRC S100 covers specimen preparation and test methods for measuring the initial and aged solar reflectance and thermal emittance of roofing products.
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.
How often is ANSI/CRRC S100 updated?
The CRRC updates ANSI/CRRC S100 approximately every three years. The primary reason for updating the standard is to incorporate changes made to the CRRC's Product Rating Program that are related to radiative properties measurement, including new test methods and practices adopted by the CRRC since the last update of ANSI/CRRC S100.
Can the public submit proposals to update ANSI/CRRC S100 or for the development of a new standard outside of a regular cycle?
Yes, proposals to update ANSI/CRRC S100 or proposals for the development of a new standard can be submitted at any time. The proposer must use the CRRC Standards Proposal Submission Form. If the CRRC is proposing revisions to an existing CRRC standard, such as ANSI/CRRC S100, and the proposal is related to those proposed revisions, then the CRRC S100 Public Comment Form (only available during a CRRC public comment period) must be used.
Where can I find a copy of the previous edition of the standard (CRRC-1 Standard 2012)?
You can download the archived standard here. CRRC-1 (2012) is superseded by ANSI/CRRC S100 (2016).
