Claiborne Elementary School won the Energy Star National Building Competition: Battle of the Buildings, sponsored by the U.S. Environmental Protection Agency.

Louisiana Controls Inc., a Baton Rouge-based member of the InsideIQ Building Automation Alliance, completed upgrades to the school’s facility controls and energy management system that helped the school to cut its energy use nearly in half.

Claiborne Elementary was among more than 3,000 buildings nationwide that spent the past year competing to obtain the greatest reduction in energy use and win the Battle of the Buildings.

The 100,892-sauare-foot school was completed in 2011. In 2012, the school’s energy costs were $2.07 per square foot, well above the old facility’s $1.59 per square foot.

Professional services manager Aramark worked with Louisiana Controls to lower energy costs to $1.32 per square foot in 2013, a reduction of 46 percent.
