Reduce Plant Energy Without Replacing Your Existing Controls
Facil.ai works through your existing building automation system to continuously optimize chilled-water plant performance. There is no new field hardware to install, no capital expenditure and no requirement to replace the BAS your operators already use.
Verify the Savings Before You Commit
Facil.ai begins with a 30-day trial at no cost. The platform integrates with the existing BAS, observes plant operation and begins making controlled optimization adjustments within the approved operating limits. Performance is measured using the facility's actual operating data.
No-cost performance trial
Capital investment required
Monthly platform fee per optimized ton
Minimum monthly savings per optimized ton
The ongoing performance target is at least twice the platform's monthly cost. Savings are reconciled monthly, creating continuing accountability rather than relying on a one-time projection.
Final pricing, eligible tonnage, baseline methodology and savings reconciliation are established during technical qualification and documented in the customer agreement.
Continuous Optimization in Five-Minute Intervals
Traditional condenser-water reset strategies generally follow fixed schedules or predetermined formulas. Facil.ai evaluates the plant's actual response every five minutes and determines whether a controlled setpoint adjustment can reduce total energy while maintaining operational requirements.

Facil.ai evaluates performance every five minutes and makes a controlled adjustment only when appropriate — it does not blindly change the setpoint on every interval.
Optimize the Plant—not Just One Piece of Equipment
Lower condenser-water temperature can reduce chiller compressor energy, but it may increase cooling-tower fan or pump energy. The objective is not simply to produce colder water. The objective is to identify the operating point that reduces total plant energy while continuing to satisfy cooling demand and equipment requirements.
Facil.ai considers changing plant load, outdoor conditions and equipment response so the optimization strategy can adapt as operating conditions change.

Total plant energy = sum of all plant energy consumers
Works With the Controls You Already Own
Facil.ai is a software-based optimization layer designed to operate through the existing building automation environment. The original BAS remains in place, along with its alarms, safeties, operating limits and operator oversight.
Not every plant automatically qualifies. Existing BAS points, instrumentation, data quality and control capability must first be confirmed.
Demonstrated in University Central Plants
California State University, Dominguez Hills
- Three 1,000-ton JCI/York water-cooled chillers
- Existing Johnson Controls Metasys BAS
- Initial focus on adaptive condenser-water reset
- Average plant efficiency reportedly improved from 0.86 to 0.45 kW/ton
- Estimated annual savings of approximately $243,639
- No new field hardware
- Results measured over an extended operating period
California State University Channel Islands
- Approximately 1.3 million square feet across 21 buildings
- Two JCI/York chillers totaling approximately 1,300 tons
- Existing Automated Logic WebCTRL BAS
- Average plant efficiency reportedly improved from approximately 1.15 to 0.60 kW/ton
- Reported 48% efficiency improvement within 45 days
- No hardware changes required
Results vary by plant. The 30-day trial establishes site-specific performance using the customer's actual plant operation and agreed measurement methodology. These case-study results are not a guarantee of customer outcomes.
Designed for Large Central Chilled-Water Plants
What We Review Before Deployment
A technical discovery session determines whether the plant has the instrumentation, BAS access and control capability required for a meaningful trial.

Let Your Plant Prove the Opportunity
Begin with a technical assessment and determine whether your chilled-water plant is suitable for a 30-day no-cost Facil.ai trial. You will evaluate the opportunity using measured plant performance—not projected savings alone.
