What is Fault Detection and Diagnostics?

Fault Detection and Diagnostics (FDD) is a software tool used to proactively discover building system problems and identify optimization opportunities before they cause problems in campus buildings. FDD has prevented alarms, excessive waste of resources, occupant discomfort or system failure by identifying issues before they lead to those critical issues. FDD is currently active in 52 buildings collects over 100,000 data points across campus.

"FDD helps our team come up with solutions to larger systemic problems rather than putting out fires at the component level. This moves us towards efficiency and optimization in how we operate our buildings."

FDD Achievements

Since it's implementation, the Fault Detection and Diagnostics program has achieved the following:

  • Addressed issues related to energy,  comfort and maintenance
  • Shifted work orders from reactive to predictive maintenance
  • Three different Building Automation Systems (BAS) integrated
  • Work order integration with FDD software for performance tracking and transparent adoption 
  • All major HVAC equipment is monitored with FDD


FDD Recognition

The Fault Detection and Diagnostics program has been recognized by organizations for its innovative and effective practices. See some examples below:
