FAULT DETECTION & DIAGNOSTICS (FDD)
Stop Managing Alarms. Start Eliminating Failures.
NETIX AI detects building faults before they become crises, diagnoses root causes, dispatches pre-built work orders, and verifies the fix actually held.

Zero Blind Spots.
WHAT IT IS
A vendor-neutral, AI-driven fault detection engine that monitors every connected building system – chillers, AHUs, RTUs, pumps, lighting, life safety – to find faults before they become failures.
A hybrid AI stack combining ASHRAE Guideline 36 rules, ML, computer vision, and NLP diagnoses root causes, ranks faults by business impact, and triggers closed-loop resolution through your existing CMMS. No rip-and-replace.
OVERLAY PROTOCOLS SUPPORTED
Core capabilities
Functional Test Template (FTT) Continuous Commissioning
ASHRAE Guideline 36 Rules +ML
Deterministic rules catch known faults; ML catches drift, slow degradation, and cross-system patterns rules can't see.
Cross-System Root Cause Analysis
Traces a chiller alarm to its true source - a stuck valve on AHU-7, a CHW sensor drift, a control logic defect - not the loudest symptom.
AI Severity Scoring
Every fault is scored on energy waste, comfort impact, equipment risk, and US compliance exposure (LL97, BERDO 2.0, Title 24).
FTT Continuous Commissioning
Functional Test Templates are re-run automatically against live data. Pass/fail evidence replaces annual third-party commissioning visits.
Pre-Diagnosed Work Order Dispatch
Confirmed faults flow into your CMMS (ServiceNow, Maximo, Planon, Facilio) with the root cause, recommended fix, and parts list pre-attached.
Closed-Loop Fix Verification
Post-repair, FTTs re-run to confirm resolution. Unresolved faults re-escalate. Every outcome logged for IPMVP audit trails.
HOW IT WORKS
From first alert to verified fix in 5 steps. No black boxes. No alert dumps. Just a clean, traceable pipeline from signal ingestion to post-repair confirmation.
