Energy Future Holdings Earns EPA ENERGY STAR Award

Business Wire, Oct 6, 2008

DALLAS -- Energy Future Holdings Corp. (EFH) is pleased to announce that Energy Plaza, which is operated by EFH, has earned the U.S. Environmental Protection Agency's (EPA) prestigious ENERGY STAR award. The ENERGY STAR is a national symbol for protecting the environment through superior energy performance. With today's announcement, Energy Plaza joins approximately 3,200 buildings nationwide that have earned the designation.

"Energy Future Holdings is very pleased to have been awarded the EPA's ENERGY STAR designation as a demonstration of our dedication to energy efficiency," said CEO John Young. "We believe in leading by example, and hope other companies will be encouraged to make a commitment to environmental stewardship in their own workplaces."

Earning the ENERGY STAR denotes that Energy Plaza uses about 35 percent less energy than average buildings, while still providing quality service and comfort to its occupants. EFH has made several cost effective improvements during the recent restructuring of Energy Plaza and will continue to explore ways to improve energy efficiency.

Organizations earn the ENERGY STAR by using EPA's national energy performance rating systems to generate energy-efficiency ratings for their buildings, on a scale of 1 to 100 relative to other buildings across the country. The ratings system is available for schools, office buildings, dormitories, hotels, hospitals and grocery stores.

ENERGY STAR is a government-backed program that helps businesses and consumers protect the environment through superior energy efficiency. In 2006 alone, Americans, with the help of ENERGY STAR, saved $14 billion and prevented greenhouse gas emissions equal to those from 25 million vehicles.
