The Energy Commission adopted the proposed amendments (final express terms) for roof coatings at its Business Meeting April 26, 2006. The final express terms have been submitted to the California Building Standards Commission (CBSC) for possible adoption at its meeting in July 2006. If the CBSC adopts the amendments, they will take effect 30 days after the CBSC files them with the Secretary of State.


At its April 13, 2005 Business Meeting, the Energy Commission voted to approve a petition to conduct a rulemaking to consider changes to one portion of the 2005 Standards: Table 118-C, "Minimum Performance Requirements for Liquid Applied Roof Coatings." The Commission considered adding an American Society for Testing and Materials (ASTM) test for liquid coatings for flexibility as an alternative to initial and aged elongation at low temperatures and to initial tensile strength.

The petition requesting a rulemaking came from an ad hoc consortium of roof coating manufacturers led by National Coatings Corporation of Camarillo, California. Prior to that petition, the Energy Commission had received a letter from the Roof Coating Manufacturers Association (RCMA), based in Washington, DC, also regarding Table 118-C of the 2005 Standards. In its letter, RCMA suggested that the Commission eliminate performance requirements altogether for liquid-applied roof coatings.

In the course of discussions, stakeholders raised a separate but related issue concerning Section 118(i)3 of the Building Energy Efficiency Standards: the minimum dry mil thickness for liquid-applied roof coatings. All of these comments were considered. The Commission's Energy Efficiency Committee consisting of Commissioners Pfannenstiel and Rosenfeld held public hearings on June 7, 2005, and April 3, 2006, to take testimony on these matters. Written and oral comments were taken per the Notice of Proposed Action and are included on these roof coatings rulemaking webpages as documents and public comments and within the hearing transcripts. The amendments resulting from these discussions are the final express terms.

Other Rulemaking Documents are located on the Documents page.
