Over past two summers, new air conditioning聽has聽been installed in 15 buildings in Ohio’s Columbus City Schools. The work, part of the district’s Operation Fix It campaign, is funded by a bond approved by voters in 2016.
“Students aren’t sweating and slumped over and exhausted from the heat,” says Nikki Myers, principal of聽Columbus’ Salem Elementary School, which got air conditioning and a new roof this summer. “It’s a wonderful upgrade that has definitely helped the learning environment.”

Myers told 91看片 that students are more attentive, and fewer children have had to go to the nurse’s office to use inhalers.
