AIR (Asset Intelligence Rating) is built to be examined. This page explains how the score is built: the scale, the four dimensions, how findings roll up, and what AIR does and doesn't measure.
AIR rates how well a building is operating — not how it was designed, and not its raw energy use. Higher is better. The bands below are guidance, not hard cutoffs; what matters is the findings behind the number and the direction it's moving.
0–59
Significant opportunity
60–74
Room to improve
75–89
Strong
90–100
Excellent
Each dimension is calculated from your trend data and linked to the issues behind it.
AIR dimensions · inputs
| Dimension | What it measures | Primary inputs |
|---|---|---|
| Energy efficiency | How much energy spend does useful work vs. leaks through faults | Simultaneous heating/cooling, economizer behavior, runtime, reset effectiveness |
| Occupant comfort | How consistently zones hold their comfort bands | Zone temp vs. setpoint, recovery times, deviation frequency and duration |
| Maintenance risk | Early behavioral signatures of failing equipment | Short-cycling, hunting, drift, abnormal runtime and start patterns |
| Controls health | Whether sequences still perform as designed | Reset engagement, loop stability, schedule adherence, setpoint integrity |
Which inputs apply depends on the points available in your building's trend data.
Within each dimension, findings are weighted by their severity: estimated dollar impact for energy, deviation size and duration for comfort, and failure risk for maintenance. A handful of expensive faults move the score more than a long tail of minor ones, so the score points you to what to fix first.
AIR is recalculated with every analysis run. When your team or contractor fixes an issue and marks it resolved, OnPoint keeps watching for improvement and the score reflects what changed. Backsliding shows up too.
AIR runs on Prescriptiv, the fault-detection engine inside OnPoint, which is built on our co-founders' building-performance research at Carnegie Mellon. The methodology evolves as deployments surface new failure modes, and each change is reflected the next time your building is analyzed.
Start with one building. If the data reveals an issue, we'll show a representative finding and its potential savings. AIR, the full ranked list, and ongoing monitoring come with a subscription.
