The University of Nebraska-Lincoln implemented a fault detection and diagnostics solution to continuously commission HVAC and mechanical systems across campus. Over 60,000 sensors generate 7.4 million daily records that trigger alerts when equipment drifts from optimal performance. The system enables remote fixes, prioritized maintenance dispatch, and avoidance of up to $25,000 in annual energy waste per air handler. Results include early detection of 1,100 faults per month and preservation of efficiency gains without periodic recommissioning.

Key takeaways

FDD solution monitors 52 buildings with 60,000+ sensors collecting 7.4 million records daily

Continuous commissioning prevents performance decline that typically occurs every five years

Early fault detection avoids up to $25,000 yearly energy waste per air handler

Remote issue resolution and prioritized technician dispatch reduce response time and cost

System supports 15% campus-wide energy reduction goal while improving occupant comfort
