LINCOLN, Neb. (AP) — Lincoln school district officials are looking to stem a spike in heating costs at three high schools.
The Lincoln Journal Star reports that the Lincoln Board of Education will consider a $1.1 million proposal on Tuesday to add cooling equipment to the geothermal systems at Lincoln North Star, Southwest and Southeast high schools.
The schools have ground-source heat pumps that use the ground to heat and cool water, which is then circulated through pipes to regulate temperature. District officials have noticed in recent years that the buildings’ circulated water was warmer than it should be because of overuse, especially in the summer.
The district’s operations director, Scott Wieskamp, estimates they’re spending up to $60,000 more a year on the buildings’ heating systems, compared to when they were first installed.
