Buildings don't fail loudly. They leak quietly.

LeanFM analyzes existing HVAC trend data to find the hidden faults your BAS alarms aren’t catching — and ranks them so your team knows exactly what to fix first.

  • No new hardware required
  • Uses existing HVAC trend data
  • Finds problems that may not trigger alarms
  • Produces clear, prioritized findings

Prioritized diagnostic finding

AHU-3 heating and cooling conflict

High Priority

Cooling and reheat appear active during occupied periods, creating avoidable energy use and comfort instability.

Up to 30% of energy spend wasted

Hidden HVAC faults that BAS alarms miss can quietly drain up to 30% of building energy spend.

Documented at a local museum where LeanFM identified BAS logic faults hiding in existing data.

Why your building automation system may miss hidden HVAC waste.

BAS alarms flag obvious failures or out-of-range conditions. Many costly HVAC issues do not look like alarms. They show up as patterns over time.

From building data to clear action.

LeanFM does not start with new hardware. It starts with the system data your building already produces.

The platform behind the findings

LeanFM delivers findings through OnPoint, our software platform, powered by the Prescriptiv analytics engine developed from research at Carnegie Mellon University. Your team reviews prioritized issues in plain English — no new hardware, no dashboards to decipher.

What we are

Software-delivered analysis of the data you already have.

Developed at Carnegie Mellon. Tested in real institutional buildings. Backed by a money-back ROI guarantee.

What we are not

  • Not a BAS replacement
  • Not an energy audit
  • Not enterprise AFDD with the install cost stripped out
  • Not generic AI for buildings

What LeanFM finds

The issues are technical underneath, but the operating impact is easy to recognize: waste, comfort risk, wear, and unclear priorities.

See What We Find
Heating/cooling overlap
Overlap window

Heating and cooling at the same time

What it looks like

Blue cooling and orange heating behavior overlap during occupied periods.

Why it gets missed

Each loop may appear normal while the combined behavior wastes energy.

What it can cost

Energy waste, comfort instability, and unnecessary equipment wear.

What LeanFM surfaces

LeanFM highlights the zones and times where the conflict appears in trend data.

Energy wasteComfort instabilityEquipment wear
Schedule vs runtime
Occupied
Actual runtime

Equipment running longer than needed

What it looks like

Actual runtime extends beyond the occupied schedule or expected building use.

Why it gets missed

Overrides and schedules can drift without creating an alarm condition.

What it can cost

Higher utility costs, avoidable runtime, and premature wear.

What LeanFM surfaces

LeanFM compares runtime patterns against schedules and building context.

Utility costUnnecessary runtimeWear
Sensor drift
ActualReported drift

Sensors causing bad decisions

What it looks like

Reported sensor values drift away from actual operating conditions.

Why it gets missed

A sensor can be wrong enough to affect control without crossing a threshold.

What it can cost

Bad control decisions, comfort complaints, and misdiagnosed problems.

What LeanFM surfaces

LeanFM flags sensor behavior that may be driving the wrong response.

Control logic faults

What it looks like

The BAS follows a sequence that no longer matches building operation.

Why it gets missed

The system may be doing exactly what it was configured to do, even when the logic is wrong.

What it can cost

Recurring issues, hidden waste, and unstable operation.

What LeanFM surfaces

LeanFM identifies control patterns worth review by facilities or controls teams.

Featured Case Study

A newer BAS can still miss costly logic faults.

A local museum had already installed a new BAS. LeanFM found logic faults hiding in the data, and the case study shows documented savings after those faults were corrected.
