Fault Detection and Diagnostics

Fault Detection Diagnostics

What is FDD?

Fault Detection and Diagnostics (FDD) is a software tool used to proactively discover building system problems and identify optimization opportunities before they lead to alarms, excessive waste of resources, occupant discomfort or system failure in 52 buildings across campus to date and over 100,000 data points collected across those buildings.

"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 do our work and how we operate our buildings."  Tom Moore, Manager, Building Operations and Maintenance
