Fault Detection and Diagnostics (FDD)

FDD is one of the highest-ROI layers of smart building programs because it targets energy waste that is invisible to schedules and setpoints. Modern FDD tools rank faults by cost impact so teams fix the most expensive problems first.

In practice

In day-to-day building management, Fault Detection and Diagnostics (FDD) is utilized by facility managers and maintenance teams to monitor HVAC systems and other critical equipment. When FDD identifies issues like energy inefficiencies or equipment failures, it informs immediate maintenance decisions, prioritizing repairs that minimize downtime. Commercially, effective FDD helps optimize energy consumption and reduce operational costs, driving significant savings. It also enhances occupant comfort and system reliability, ultimately improving overall building performance and tenant satisfaction.
