The Problems Your Building System Isn’t Showing You

LeanFM analyzes existing building system data to uncover hidden issues that waste energy, impact comfort, and strain equipment—often without triggering alarms.

Issues that quietly increase operating costs
Problems that hit comfort before alarms
Inefficiencies that add up over time

Most Systems Show Data—But Not the Full Picture

Building systems generate large amounts of data, but many issues never trigger alarms. Instead, they show up as patterns over time.

The costliest problems are often the ones that go unnoticed.

Why These Issues Get Missed

Your BAS alerts you when something is clearly wrong. But waste, drift, and inefficient operation often develop gradually. They may not cross an alarm threshold, but they still affect energy use, comfort, and equipment performance.

Your system runs “within range” while still wasting energy

Alarms don’t fire because nothing has technically failed

Patterns are hard to see without looking across time and equipment

Facilities teams rarely have time to manually review thousands of data points

Hidden Issues That Become Real Operating Problems

LeanFM turns technical BAS behavior into issues a facilities, operations, or finance team can understand and prioritize.

Heating/cooling overlap

Heating and cooling at the same time

What it looks like

Your system may be paying to heat and cool the same space simultaneously.

Why it gets missed

Each control loop may look acceptable on its own, while the combined behavior wastes energy.

What it can cost

Energy waste, comfort instability, unnecessary equipment wear

What LeanFM surfaces

LeanFM surfaces the zones and operating periods where heating and cooling appear to overlap.

Energy wasteComfort instabilityEquipment wear

Schedule vs runtime

Occupied

Actual runtime

Equipment running longer than needed

What it looks like

Fans, pumps, or units may be operating when the building does not need them.

Why it gets missed

Schedules and overrides can drift slowly, especially across buildings with changing occupancy.

What it can cost

Higher utility costs and avoidable wear

What LeanFM surfaces

LeanFM identifies runtime patterns that do not match likely building need.

Utility costUnnecessary runtimeWear

Sensor drift

Sensors causing bad decisions

What it looks like

A drifting or faulty sensor can make the system respond to the wrong conditions.

Why it gets missed

A sensor can be wrong enough to affect control decisions without crossing an alarm threshold.

What it can cost

Comfort complaints, wasted energy, and misdiagnosed problems

What LeanFM surfaces

LeanFM flags sensor behavior that may be causing the BAS to respond to the wrong conditions.

Control logic faults

What it looks like

The BAS may be following rules that no longer match how the building actually operates.

Why it gets missed

The BAS may be following configured logic, even when that logic no longer matches building use.

What it can cost

Hidden waste, unstable operation, and recurring complaints

What LeanFM surfaces

LeanFM highlights logic patterns that deserve review by facilities teams or controls vendors.

Recurring issuesHidden wasteUnstable operation

Stability band

Comfort drift

What it looks like

Spaces can slowly move outside preferred conditions without triggering obvious alarms.

Why it gets missed

Conditions can move gradually enough that they become complaints before they become alarms.

What it can cost

Tenant, staff, student, visitor, or artifact risk depending on vertical

What LeanFM surfaces

LeanFM shows where comfort-related conditions are drifting or behaving inconsistently.

Maintenance priorities buried in noise

What it looks like

Teams often have too many alerts and not enough clarity.

Why it gets missed

Teams see too much noise and not enough context about which issue matters first.

What it can cost

The wrong problems get fixed first

What LeanFM surfaces

LeanFM turns scattered signals into a prioritized list your team can review.

These Problems Rarely Appear as Clear Alerts

Most of these issues do not show up as alarms. They appear as patterns across time, equipment, and conditions.

Without a way to analyze those patterns, they often go unnoticed.

Turn Patterns Into Clear Findings

LeanFM analyzes your building system data to identify these patterns and turn them into clear, prioritized issues your team can act on.

LeanFM does not replace your BAS or controls vendor. It helps reveal which issues deserve attention.
