Cool Cars Workshop Scheduled for September 16 in Calif.; CARB to
Develop Performance-Based Test Procedure for Solar Heat Gain Reductions
July 20, 2009
The California Air Resources Board (CARB) has announced that it
will hold a workshop to develop a "Cool Cars" performance-based
test procedure for 2016 and subsequent model-year vehicles. This
will be the group's first workshop since the Board approved the
"Cool Cars" regulations, which call for new cars sold
in California, starting in 2012, to be equipped with glass that
reflects or absorbs the sun's rays. (CLICK

Under the terms of the regulation, over a three-year period starting
in 2012, windows in new cars sold in California must prevent 45
percent of the sun's total heat-producing energy from entering the
car, with the windshield rejecting at least 50 percent of the sun's
energy. In 2016 car manufacturers will be required to install windows
in new cars sold in California that prevent at least 60 percent
of the sun's heat-producing rays from entering the cars interior,
or propose alternative technologies to achieve an equivalent result.
Development of a test procedure that would provide car manufacturers
with the option of meeting the solar heat reduction equivalent to
that provided by the glass that is capable of blocking 60 percent
of the sun's radiation will be the focus of the upcoming workshop.
The workshop will be held from 1-4 p.m. at the CARB office in El
The new glass regulations are part of the state's efforts under
its climate change legislation, AB 32, enacted in 2006, to reduce
greenhouse gas emissions from vehicles.
