In April 2014, Dave Spooner, Supervisor of Maintenance & Construction at Duluth Public School District, enrolled six building operators in the Building Operator Certification (BOC) class in Cloquet, MN. As a supervisor, Dave was interested in the BOC program because it helps empower the employee and gets them thinking critically about energy use in buildings.

“The BOC program provided our employees some good knowledge and perspective on how they can utilize the new technology we have to provide a better service to our users and yet save energy,” Dave said.

Upon graduating from the BOC training, these professionals recommended reducing the unnecessary run-time of 37 air handling units and 50 exterior building lights in five schools within the district.

These free (and relatively minor) adjustments result in an annual energy savings of $4,800 or 130,000 kWh.
