Lyon College is taking steps to reduce energy usage on its 136-acre campus.
The college is in the process of completing a retrofit of all the campus's lighting.
Sodexo Facilities Director Jade Anderson said many of the college's lights use 28 or 32-watt fluorescent blubs, but those will be replaced with T8 25-watt fluorescent bulbs, which are more energy efficient.
Anderson said all fixtures using incandescent lamps will be replaced with compact fluorescent lamps (CFL). CFLs use approximately 75 percent less energy than a traditional incandescent bulb and last at least six times longer, according to Energy Star.
Chandelier lights will be switched to LED lights.
Anderson said the college is also adding motion sensors to its light switches so the lights will automatically shut off if a room is not in use. Ultrasonic ceiling sensors will be used to detect if there is any noise in a room and will shut off the lights if no noise is heard.
In all, 4,682 light fixtures will be changed to more energy efficient lighting.
All of the light bulbs removed will be recycled, and the new fixtures are constructed of 100 percent recyclable materials.
Crews already have added aerators to water faucets to reduce flow. Anderson said the move will save an estimated $50 per fixture per year.
Vice President for Business and Finance Ken Rueter said the upgrades are estimated to save the college between $80,000 and $85,000 annually.
"The project will pay for itself in three or four years," Rueter said. "After that time, it will be pure savings."
The first phase of the project should be complete early this month with additional lighting changes in a second phase slated for later.
