In 2012, the CTA headquarters building was awarded Leadership in Energy and Environmental Design (LEED) Platinum certification (see also: press release), an upgrade from the LEED Gold certification received in 2007.
LEED certification is sponsored by the U.S. Green Building Council to recognize buildings which meet established standards in recycling, design, energy efficiency, material selection and indoor environmental quality.
CTA's headquarters building has been awarded the Energy Star label each year from 2005 through 2012 by the U.S. Environmental Protection Agency and the U.S. Department of Energy.
The Energy Star label designates buildings that save money and protect the environment through use of energy-efficient products and practices.
