“The U.S. federal government is taking a leadership role in energy efficiency for federal buildings both through existing mandates, as well as President-elect Obama’s American Recovery and Reinvestment Plan, which calls for the renovation of public buildings to make them more energy efficient,” said Chuck Swoboda, Cree chairman and chief executive officer. “Installations of highly efficient, low-maintenance LED lighting, like these in the Pentagon and in the U.S. Federal Reserve, demonstrate that the future of energy-efficient lighting is here today.”
