Why Facil.AI

Don’t replace your BMS.
Improve its performance.

Facil.AI works through your existing BMS to improve how equipment operates. Your controls stay in place; the intelligence behind their operation changes.

  • Observe

    Read live operating data through a plug-and-play software gateway.

  • Learn

    Learn the relationships between operating conditions and equipment performance.

  • Act

    Adjust equipment setpoints through the existing BMS, within each machine’s operating envelope.

  • Oversee

    Your team sets operational goals and monitors performance while the agents handle recurring control work.

Always on. Always learning. Always optimizing.

Fácil = easy

The name says it.

Fácil is Spanish for easy. That is the whole idea. Facil.AI works through the building systems you already run, so onboarding never starts with a rip-out or an equipment list.

  • Nothing replaced

    Your BMS, controls and equipment stay exactly where they are. Facil.AI works through them.

  • Nothing added

    No new hardware on the plant. A plug-and-play software gateway connects to your existing BMS.

  • Nothing up front

    No CapEx and no capital replacement project before the agents start work.

Easy to start. Easy to run. Easy to oversee.

Track record

Proof from a working central plant.

Scatter chart of central-plant efficiency in kilowatts per ton from September to November 2025: readings cluster near 1.2 kW/ton under PID control alone, then settle near 0.62 kW/ton once the AI is running alongside PID.
Plant efficiency in kW/ton over the trial, from the published case study. Lower is better.

48%Central-plant efficiency · one campus

California State University, Channel Islands improved its central-plant efficiency by 48%.

Facil.AI's published case study follows a campus central plant run by a lean facilities team, with no capital budget for upgrades. The result is specific to that plant. What your plant can achieve starts with a look at how it runs today.

Equipment and agents

Which building systems does Facil.AI optimize?

Six agents, each built for one equipment family and using the same learning and control method. Best suited to buildings with a BMS and connected mechanical plant, where energy performance and operating workload matter.

Central plant and chillers

  • Central Plant/Chiller

    Increases overall plant plus individual chiller efficiency through improved heat rejection at the cooling tower(s).

HVAC and air side

  • Portfolio RTU

    Increased comfort and reduced costs across hundreds of RTUs in a portfolio.

  • AHU

    Dynamically manages air distribution and thermal conditions.

  • Air Source

    Balances outside versus conditioned air dynamically.

Refrigeration

  • Refrigeration Rack

    Increased energy efficiency through AI enhanced “floating” control.

  • Defrost

    Dynamic scheduling of defrost cycles, using AI store traffic analysis.

With Cool Estate

A Canadian partner from first call to rollout.

Facil.AI builds the technology. Cool Estate helps Canadian building owners identify where it can improve performance, define the project scope and support rollout through their existing building systems.

  1. Scope

    Confirm the BMS, the plant on site and what you want to improve.

  2. Connect

    Connect through a software gateway to the controls already on site. Nothing replaced, no equipment added.

  3. Run

    The agents run the plant unattended while your team oversees the results.

See whether Facil.AI fits the plant you run.

Starting is the easy part. Twenty minutes with Cool Estate: your BMS, your plant and where the agents could start.
