Xenia Community Schools: Warner Middle School Lighting and Controls Upgrades
Warner Middle School is the only middle school in the nine-building portfolio of the Xenia Community School District located in Xenia, Ohio. Built in 1962, Warner was an aging facility in need of upgrades to lighting and building controls. The 14 month project resulted in an annual energy savings of 16 percent and annual cost savings of $27,500.
Warner serves 900 students in grades 6-8. In addition to classrooms and administrative offices, the school site also houses a garage where repairs are made to district buses when needed.More
As part of an energy savings performance contract, the district identified two main savings opportunities: upgrading garage lighting to LEDs and an energy service agreement to include building HVAC controls. Combined, the upgrades are expected to pay for themselves in less than two years.More
The garage contained mostly metal halide lights which required long restart times, thus resulting in the lights being left on throughout the day. The lights in the garage were upgraded to LED and occupancy sensors were installed. In addition, the HVAC control sequences were verified, corrected, and improved. The district provided ongoing remote analysis of the building to ensure it continued to function efficiently.

Upgrade of metal halide and T12/T8 to LED with occupancy sensors, reduced lighting wattage from 460 W per fixture to 108 W per fixtureLess
Since implementation, Warner has realized a significant reduction in its energy cost per square foot to $0.62/ft2, making it the 3rd lowest energy consumer in the district. In addition, HVAC equipment is running less often thus extending the life of the equipment. The LED lighting has a longer lifespan than the older technologies, reducing the need for constant maintenance and repairs.More
