Labelling BMS Anomalies: What Counts as a Real Finding
Real means four different things at once. Split the label, keep an uncertain value, and measure how much two reviewers disagree.

Data Readiness for Anomaly Detection on BMS Telemetry
Most pilots fail on data history, not on method. Run the readiness checks per point first, and scope the pilot to what passes them.

BMS Point Naming and Cross-System Joins: Why Names Fail as Keys
Names get corrected, restructured and reused. Join on a stable surrogate identifier and keep one owned, versioned, queryable crosswalk.

BMS Data Access Policies for the Collected Copy
The collected copy needs its own policy. Classify by what the data reveals, enforce in the store, and treat export as the highest risk.

Facility Data Backup and Restore Testing That Proves Something
A backup you have never restored is a belief, not a control. Inventory the pieces, set loss windows per piece, and test them together.

BMS Trend Logs vs Historians: Which One You Actually Need
Controller trend logs are bounded and system-scoped. Three real questions and two boundaries tell you whether you need a separate store.

Raw Versus Aggregated BMS Readings: What Rollups Remove
Aggregation is not compression. It removes variability, duration and sequence. Choose the functions from the questions you expect to ask.

BMS Time-Series Storage Sizing: Getting the Inputs Right
The arithmetic is simple and the inputs are not. Measure a real week, size per retention tier, and cost it as years of retained history.

Migrating BMS Point History When Replacing a Head End
The identity problem is harder than the volume. Build the point crosswalk and take the export while the old system still runs.

Handling Duplicate Sensor Readings in a Building Time-Series Store
Retries, replays and second collection paths create duplicates. Choosing a reading identity and enforcing it where data lands.
