Lander University in Greenwood, S.C., relied on a programmable relay-based system installed in the mid-1980s to provide energy-saving scheduled control of lighting and equipment for its most vital buildings.
While the system, which controlled the learning center, cultural center, student center, and athletic complex, served its purpose initially, the controls had become antiquated and unreliable. After experiencing numerous disruptions to classes and events, engineers at the state university set out to research replacement options. The school’s engineering services department personnel priced equipment and installation costs, and eventually found a solution.
For less than 10% of the cost of a new system, they could refurbish the existing panels to create a modern control system. The university could significantly extend the life of its capital equipment and avoid sending materials to a landfill. Additionally, the upgrade would take much less time than a full replacement.
