Try Plant Check

Pilot program

A small number of plants, measured properly

We're looking for water-cooled chiller plants to pilot advisory optimization of the condenser-water loop, with a monthly verified report.

Now selecting first pilot sites.

How onboarding works

From a trend export to your first monthly report

A pilot starts with data your BMS already keeps. No hardware needed to start, no network changes, and nothing is written to your equipment.

  1. Step 1

    Send a trend export

    Your BMS already logs chiller power, loop temperatures and flows. Export a month or more as CSV; we send point-by-point instructions for common BMS platforms. No hardware needed to start, no network changes.

    Your timeTypically under an hour

  2. Step 2

    We map and baseline

    We identify every point (the AI proposes, an engineer checks), run the physics checks and build your baseline.

    Your timeOne short call to confirm the point list

  3. Step 3

    Recommendations you approve

    Specific setpoint and water-side recommendations. Your operators accept or reject each one. Nothing is written to your equipment.

    Your decisionAccept or reject each one

  4. Step 4

    Monthly verified report

    kWh and gallons against your baseline, guardrails, and dollars at your tariffs. When you'd rather not send files, a cellular gateway we install, off your IT network, replaces the monthly export.

    You receiveA verified report every month

What we need from you
  • A BMS trend export (or read-only access later)
  • Water-treatment service logs, if you have them
  • Your utility tariffs
What we never do
  • Write to your controls without approval
  • Replace your BMS, your water-treatment company or your qualified person
What we add where it helps
  • Read-only flow meters on make-up and blowdown lines
  • Conductivity sensing where your tower controller doesn't log it
  • A cellular gateway, off your IT network, so reports run without exports

Most exports cover the chiller side well and the water side poorly. We supply and install these, priced separately from the service, so water savings can be measured, not estimated. None of it is needed to start.

Good fits

  • Water-cooled chillers with cooling towers
  • A BMS that trends chiller power, loop temperatures and flows (we can help check)
  • Plants that run most of the year: hospitals, campuses, labs, data rooms, warm climates
  • An owner or engineer who wants measured results, not promises

What does your BMS trend?

Tick the points your building management system logs. The count uses the same metric requirements as Plant Check.

Points your BMS trends

Plant Check could calculate 0 of 25 metrics from these points

Every metric first needs: Chiller power; either Chilled-water flow + Chilled-water supply temperature + Chilled-water return temperature or Measured cooling load.

Also useful for a pilot (not used by Plant Check): tower water logs (conductivity, cycles), chemical feed records, Legionella results, utility bills
