The White House Better Buildings Challenge has saved participants more than $1 billion in just two years, according to a recent review of the program.
More than 250 partners have signed on to the challenge, which calls for a 20 percent energy reduction over 10 years.
The program launched in 2011 and had more than 7,000 buildings participating in 2012. In 2014, that figure more rose to 32,000 buildings, with an energy cost savings of $840 million last year alone.
