What's New List Serve Post Display

The Air Resources Board revised draft regulatory language has
been posted.  It can be found on ARB's website at
http://www.arb.ca.gov/cc/cool-paints/cool-paints.htm or may be
requested from ARB’s Emission Research and Regulatory Development
Branch at (626) 575-6632.  

Of note, the proposal now specifies solar control requirements
only for new vehicles windows (glazing).  The original proposed
regulation contained requirements for both vehicle paint and
windows to improve their ability to reflect heat from the sun. 
The intent of the paint requirements was to introduce reflective
paint (currently used in architectural paints to keep houses and
businesses cool) into the automotive arena. The requirement was
never at any point to limit consumer color choices or ban any
colors. Based on input from the automotive industry, paint,
pigment suppliers, and comments from a public workshop held on
March 12th, ARB staff has determined that a clear path to achieve
solar reflectivity for the darker colors has not yet been
identified. We are planning to address the paint-related portion
of the proposal in a future regulatory action. 

Staff has also changed the glazing requirements from a
reflective (Rds) to a Total Solar Transmission (Tts)
specification.  This metric more closely aligns with the
proposal's goal of limiting solar transmission into the vehicle. 
In an effort to get the newest draft of the regulation out to
stakeholders some numerical values are not currently indicated in
the draft regulation.  The intent is to provide the framework of
various compliance options.  The numerical value will be
specified in the final draft of the regulation which will be
released 45-days prior to the June 25-26, 2009 Board Hearing.
