How LeanFM works

From BAS trend data to verified HVAC priorities.

LeanFM reads an export or approved read-only connection from the BAS you already run, diagnoses hidden HVAC faults, and shows your team the evidence, likely root cause, financial impact, and result after the fix. No new sensors. No control writes.

01 — The workflow

Diagnosis first. Control stays with your team.

01 · USE

Use existing BAS data

Start with trend exports or an approved read-only connection from the system already in place.

02 · DIAGNOSE

Diagnose hidden faults

Find control, schedule, sensor, and equipment patterns that individual alarms do not explain.

03 · PROVE

Show the evidence

Attach the trend, likely root cause, confidence, recommended action, and annual impact.

04 · PRIORITIZE

Fix in dollar order

Your facilities, BAS, or service team chooses and performs the corrective action.

05 · VERIFY

Verify the result

Re-read the data after the fix and report identified and captured savings separately.

02 — Supporting capabilities

The diagnosis stays central. The tools help each team use it.

03 — Data boundaries

Read-only by default. Nothing touches your controls.

Read-only access

We analyze a data export. OnPoint never writes to your BAS or changes a setpoint.

Your data, your control

Trend data is used only to run your analysis — never sold, never used to train shared models without your agreement.

Any major BAS

Johnson Controls, Siemens, Honeywell, Automated Logic, Delta, and mixed-vendor campuses.

No new hardware

Nothing to install, wire, or maintain. The data you already collect is enough to start.

04 — Where LeanFM stops

HVAC diagnosis without taking over the building relationship.

Not a BAS replacement

Your existing building automation system remains the control layer.

No control writes

LeanFM does not change setpoints, schedules, or control sequences.

No technician dispatch

Your facilities, controls, or service team owns corrective action.

Not the system of record

LeanFM supplies diagnosis, prioritization, and verification—not a replacement workflow system.
