Frequently Asked Questions

What is FDD (fault detection and diagnostics)?

FDD combines real-time detection with root-cause analysis to surface critical issues, reduce false alarms, and enable smarter maintenance planning.

What are the four diagnostic methods?

The most used methods are statistical analysis, rule-based logic, physics-based models, and data-driven machine learning techniques.

What is a fault detection system?

A fault detection system continuously monitors building data, flags anomalies, validates them, and helps teams act on verified issues faster.

What is meant by diagnostics?

Diagnostics analyzes the detected fault, pinpoints the exact issue, and guides the corrective action needed to resolve it.

Why is fault detection important?

It prevents unexpected failures, reduces energy waste, improves occupant comfort, and minimizes costly downtime across your sites.

What are the 3 common fault diagnostic techniques?

They typically include rule-based diagnostics, model-based analysis, and machine-learning–driven pattern detection to pinpoint root causes.

What is the difference between fault detection and diagnosis?

Fault detection identifies when something is wrong; diagnosis explains why it happened by finding the root cause and its impact.

What are considered diagnostics in building operations?

Diagnostics include identifying why equipment underperforms, analyzing sensor data, validating faults, and recommending corrective actions.
