Building Performance Intelligence

Find hidden HVAC wastebefore it becomes a problem.

LeanFM reads the building automation data you already collect — analyzed by Prescriptiv, our engine developed from Carnegie Mellon research — to uncover energy waste, comfort issues, and maintenance risks. No new sensors required.

01 — The problem

Buildings don't fail loudly. They leak quietly.

Your BAS alarms on thresholds — a fan fails, a sensor flatlines, you hear about it. But simultaneous heating and cooling, a stuck economizer, a schedule that never matched occupancy? Those run silently, sometimes for years, quietly burning five to six figures a year in a single building.

Up to 30%1

of HVAC energy spend is lost to hidden faults like these.

Waste accruing daily

Same building. Same day.

Figures from independent building retro-commissioning research. Individual results vary by building; LeanFM's findings are reported per building from your own data.

02 — Detection

Eight faults that hide in plain sight.

Read-only access to the trend data you already produce — analyzed by Prescriptiv, our fault-detection engine developed from Carnegie Mellon research, then reviewed by engineers who do commissioning.

Simultaneous heating & cooling

Two systems fighting in the same air — comfort holds, cost doubles.

Economizer faults

Dampers stuck or mis-sequenced, paying for cooling the weather would do free.

Schedule vs. occupancy

Equipment running nights and weekends for empty rooms.

Sensor drift & failure

Sensors reading wrong, so controls act wrong everywhere downstream.

Setpoint drift

Overrides that never got reset, compounding year over year.

Runtime inefficiencies

Cycling, short-starts, and hours far beyond what load requires.

Control sequence problems

Loops that hunt, resets that never engage, sequences drifted from design.

Airflow sensor failures

Flow stations reporting fiction while the BAS reports normal.

We find them in the data
your controls already produce.

No sensors to install. No sequences touched. Just the trend logs your building has been writing all along — finally read closely.

03 — The score

One score for the whole building — and it shows its work.

AIR (Asset Intelligence Rating) rates building performance from 0–100 across energy, comfort, maintenance risk, and controls health — computed from your BAS trend data and updated with every analysis run. Open any rating and see the findings behind it: which equipment, which fault, which dollars.

04 — The advisor

Meet Maple. Your virtual commissioning engineer.

Ask why the third floor runs hot, why a unit's runtime jumped, or what to fix first before budget season. Maple answers like a senior engineer — with the trend data, the root cause, and the recommended action. Not a chatbot. A colleague grounded in your building's data.

Why teams trust it

We show our work.

Born at Carnegie Mellon

Prescriptiv, our fault-detection engine, grew out of Carnegie Mellon research.

Explainable by design

Every finding shows its evidence — the trend, the root cause, the dollars. No black box.

Read-only by default

We analyze a data export. Nothing connects to your controls; nothing changes in your building.

Engineers behind the engine

Findings are reviewed by people who do commissioning before they reach you.

Send us trend data from one building and we'll return a sample analysis — real findings with real dollar values, no commitment. We'll confirm timing on a 20-minute scoping call.
