The World Headquarters of my blog host Owens Corning has earned the Environmental Protection Agency's Energy Star certification. This means the Toledo, Ohio building is in the top 25 percent of energy efficient buildings in the United States. Buildings are rated on a scale of 0 to 100 and the Owens Corning building received a rating of 76. The Energy Star program compares buildings of similar square footage on factors such as energy use, the number of people who work in the building, operating hours and the number of computers. During the past eight years the WHQ has reduced energy use by 25 percent and has saved more than $1.7 million in electricity costs. Some savings came from a 2001 program that asked employees to submit energy-saving ideas. Actions taken as a result of the program included reducing the time parking lot lights are on, eliminating some lights in the atrium and placing "turn off lights" signs in meeting rooms.
