10 EFFICIENT LIGHTING
What Is A Footcandle?
In the 1980s, the Village of Daykin was granted the Daykin Public School, which was built in 1935. Prior to the transfer of the property to the village, an addition was added to the school in 1962. Today, some of the original lighting fixtures that consist of incandescent bulbs or older fluorescent technology are still in use.
consumption and En- ergyWiseSM Incentive Programs. Nebraska Public Power District in partnership with their wholesale utility customers sponsor En- ergyWiseSM Programs which offer a wide range of incentives designed to help save energy, money and contribute to a more sustainable future for all Nebraskans.
The first step to a potential and successful lighting upgrade project is to complete a
lighting audit. To
assess the com- munity building’s lighting issues and complete a lighting audit, Cory first used a light meter to measure footcan- dle levels in ar- eas of concern.

Jeremy VanWesten, Daykin Village Maintenance Worker, contacted Norris Public Power District with his concern about the efficiency of the outdated lighting fixtures in the school, which is now Daykin's Community Building, and the en- ergy they consume. To analyze the lighting systems and their energy use, Peggy Tilgner, Daykin Village Board Member, and Jeremy met with Vicky Jurgens, Norris Public Power District’s Communication Coordinator, and Cory Fuehrer, Ne- braska Public Power District’s En- ergy Efficiency Program Manager, to discuss lighting issues, energy
After measuring
footcandle levels,
evaluating the
existing lighting fixtures and cal- culating approximate energy costs per area, Cory completed a lighting audit that offered suggestions on upgrading the community build- ing to light-emitting diode (LED) technology to achieve significant energy savings. The audit results
*The IES has established recommended average footcandle levels to ensure adequate illumination and safety for occupants.
Norris Public Power District customers can benefit from savings on their monthly bills as a result of identifying where they may be wasting valuable energy and choosing to make energy efficiency upgrades.
According to the U.S. Department of Energy (DOE), when compared to traditional lighting, light-emitting diode (LED) lighting uses at least 75% less energy, and lasts up to twenty-five times longer, than incandescent lighting.
