Arkansas City's school district has been named an Energy Star Leader by the Environmental Protection Agency.
More than 100 organizations are on the Energy Star Leaders list now, including commercial real estate companies, health care systems, school districts, supermarket operators and hotel managers.
Energy Star Leaders must meet one of two energy efficiency improvement milestones. The first requires a 10 percent energy reduction across the entire building portfolio. The second, known as top performer, requires the buildings in an organization's portfolio, on average, to perform in the top 25 percent of similar buildings nationwide.
The Ark City school district lowered its energy consumption by more than 21 percent during 2009 and has been designated a top performer by EPA. The Bonner Springs-Edwardsville district also received the designation.
The only other Kansas organization on the list is the Maize school district, added for 2008.
