The same gate, on a chiller instead of a packing line.
Building systems are the reference deployment for everything the platform claims: an agent that reads meters and BAS points, reasons about whether the schedule is right, and holds only the reach you granted it. Same admission gate, different equipment.
What the agent reads and writes
- BAS / BMS
- The existing building automation system stays in control; the agent reads what it reports and reasons about it
- AHU and chiller plant
- Air handling and chilled water, where most of the load and most of the waste sit
- Setpoint drift
- Where the schedule says one thing and the equipment has been doing another since a tenant complained
- Economizer
- Free cooling that is either working or has been failed closed for a year without anyone knowing
- EUI
- Energy use intensity, by area and by period, from retained readings rather than assembled at year end
- Off-shift base load
- What the building draws when nobody is in it, which is the cheapest thing to fix and the least often measured
Energy disclosure and standards
Commercial buildings are increasingly subject to mandatory energy performance disclosure rather than voluntary reporting, with an expanding set of city and state ordinances requiring benchmarked energy use to be filed annually and, in some jurisdictions, penalising buildings above a performance threshold.
The reporting asks for defensible numbers over a period. Readings retained with the identity of the model that produced them, timestamped and immutable, are a materially different position at audit than a figure assembled from a spreadsheet after the fact.
Which ordinances and thresholds apply depends entirely on jurisdiction and building size.
What a failed economizer costs for a year
Economizer faults are among the most common and least detected failures in commercial HVAC, because a building with a failed economizer is still comfortable. Nothing complains. The only symptom is the bill, and the bill has too many other variables in it for anyone to isolate the cause from the invoice alone.
Typical annual cost of a single failed economizer on a mid-size commercial building: . Estimated share of commercial rooftop units operating with an undetected economizer fault: .
This is the class of fault an agent is well suited to: it is invisible to occupants, obvious in the data, and nobody's job to look for.
Where it reports
- BAS and building automation — through governed interfaces, reading what it already reports
- Energy and sustainability reporting — including EUI by period
- CMMS work orders — where a fault rather than a schedule is implied
- Existing dashboards — via outbound webhooks
- A retained record — of every reading and every change proposed
What actually runs, and where
- Task
- Signal models over meter, sensor and BAS data, with CV where only a gauge exists
- Typical target
- x86_64 gateway or Raspberry Pi 5, alongside the existing BAS
- Mode
- Continuous sampling with scheduled reporting
- Reach
- Whatever you grant. Read-only, or setpoints you name explicitly
The controls, the interlocks and the equipment safeties stay exactly as they are. Where you grant a setpoint write, it is scoped to named equipment within bounded ranges, and every change is recorded against the agent that made it.
Start with one building.
Send a year of meter data and your BAS point list. The free audit comes back with where the load actually goes and what a first agent would watch.
