How it works: Trend Analysis

Unoccupied facility. Mid-February Sunday afternoon in Northwest Ohio and outside temperature got above 50 degrees. Chiller outside air set point enabled at above 50 degrees. One of the secondary criteria settings was building humidity. And one of the building humidity sensors failed, reading 104%.

Electrical demand spiked when the chiller was enabled. DIBS Building Optimization Specialist alerted client to situation, faulty humidity sensor was replaced, and enable logic corrected.

Bottom line: worked, ultimately saving client future energy costs and reducing wear and tear on equipment.
