The project includes 102 measures, encompassing various upgrades to the mechanical, electrical and plumbing systems in all district buildings. The measures were identified by an audit that determined the current energy use and the energy conservation measures that can be implemented to produce energy savings. When completed, the upgrades are expected to save the district $1,467,245 annually in energy costs, with 49 percent of that savings from solar. The district will also receive $920,064 in energy incentives from the state. Prior to the upgrades, the district's annual energy expense was $2,369,283, officials said.
