SensorGuard monitors valves, dampers, and sensors. When something contradicts itself, you get a clear diagnosis with proof, not a vague anomaly score.
A stuck valve or drifting sensor often looks “fine” in the BAS. The controller compensates, comfort drifts, and energy waste accumulates until someone gets a complaint.
SensorGuard looks for contradictions and consistency breaks between redundant signals and expected relationships, so you catch faults earlier and route the right work order.
Instead of flooding operators with threshold alarms, alerts include a concrete reason: which points disagreed, by how much, and when the pattern started.
No hardware. No installation. We do the work.
Export trend data from your BAS as CSV or Excel — something you already do for energy reports. Or schedule a 15-minute call and we'll walk you through it.
Our TNA engine compares every command/position pair and measured/setpoint pair in your data. Stuck valves, offline chillers, control loop failures — all detected automatically.
A branded PDF report with every fault found, severity, estimated annual cost, and recommended fixes. Most buildings have 3–5 faults costing $8,000–20,000/year in waste.
Command says 80%, position reads 5%. The actuator failed mechanically but your BAS shows no alarm — it's sending commands into the void.
Measured SAT is 68°F while setpoint is 55°F. The chiller might be undersized, the valve might be stuck, or the coil is fouled. Either way, tenants are hot and you're wasting energy.
CHW supply at 79°F when setpoint is 44°F. The chiller tripped, the lead/lag sequence failed, or the cooling tower is degraded. Cascading comfort complaints incoming.
Outdoor air damper commanded to 30% but reads 100% open. In January that's thousands of dollars in heating energy blowing through a stuck damper.
When SensorGuard alerts, it shows the contradiction that triggered it. Clear work-order language, minimal tuning, and fast time-to-value.
The result: faults that remain invisible to rule-based systems — subtle actuator failures, slow-drift control loops, masked equipment degradation — become mathematically provable. No heuristics. No tuning. No false alarms.
No enterprise contracts. No hidden fees. Cancel anytime.
Most building analytics platforms require 6-figure contracts and 3-month implementations. We don't.
Proven across benchmark datasets and real-building style scenarios before we ever touch your data.
Avionics-style logs and building/HVAC benchmarks — same engine, proven across domains.
Actuator stuck, sensor bias, and cascade tracking — tested on benchmark and real-building style data.
Command vs position contradictions and typed disagreement states attached to every finding.
Designed for facility teams: clear work-order language covering what failed, where, and why.
Read-only by default, clear data handling, and flexible options for cloud or on-prem.
