Most BMSs
can be controlled.
Exergio buildings
can think.
The building operations triad
Owners, asset managers and facility managers — finally working in unison.
In most buildings, the three roles responsible for performance don't share a system. Owners get quarterly PDFs. Asset managers chase updates via email. FM teams firefight whatever didn't get caught upstream. Exergio collapses that fragmentation into one live, supervised platform.

How it integrates
No rip-and-replace.
Live in about two hours.
Exergio plugs into the BMS already running your building — Schneider, Siemens, Honeywell, Trend, Wago, Niagara — via BACnet, Modbus or OPC UA. A small secure gateway (Teltonika TRB140, 10×10 cm) goes on site. From there, the AI engine runs in the cloud, and every algorithmic change is reversible with one click.
Integrate
Connect to the existing BMS via BACnet / Modbus / OPC UA. No new hardware in the controllers. Historical data ingested in hours,
not weeks.
Diagnose
The AI reads ~10,000 BMS data points per hour. Setpoint drift, sensor faults and competing
HVAC strategies are surfaced as a ranked list, not a wall of alarms.
Optimise
Continuous retuning of HVAC, AHUs, chillers, heating stations and free cooling — based on real occupancy, weather and (where relevant) day-ahead energy prices.
Supervise
A named Dedicated Building Engineer reviews every change,
validates savings against the meter, and is the on-call partner for the client team. No black box.
The platform
Six things a stand-alone BMS
does not do.
Each capability below is in production today across our 367-building portfolio. The visuals are pulled directly from the live product — comfort scoring, fault detection, dashboards and the assistant chat.
01 · Comfort first
Tenant comfort is the metric.
Energy savings follow.
Most platforms optimise for energy and let comfort drift. Exergio
inverts that. Every room controller (RC) is continuously scored
against the agreed comfort KPI — temperature stability, setpoint
hit rate, morning warmup, occupied vs. unoccupied behaviour.
820 devices, scored hourly against the comfort KPI
Comfort risks classified before tenants complain
Investigates "high setpoint vs. other occupied rooms" patterns that
indicate technical fail
"Too cold in the morning" flagged separately from energy issues
From the RC Comfort Classification engine
02 · Predictive maintenance & FDD
Catches the fault before the guest, the tenant or the asset manager does.
The same physics model that scores comfort cross-checks every actuator, valve, sensor and heat-recovery wheel against expected behaviour. Heat-recovery failures, actuator stiction, sensor drift, hydraulic limitations — all surfaced days or weeks before they break a room.
Live floor-plan view of every room and AHU
Each issue gets a verdict, a duration,
and the parameters at the moment of failure
Work-order, complaint, or "solve in chat" — handled in one workflow
Up to 60% less engineer time across the portfolio
03 · Plays the energy market
The building becomes
an energy storage asset.
Exergio ingests next-day spot prices (Nord Pool, RDN in Poland, day-ahead curves anywhere they're available) and constructs an hour-by-hour operating plan that minimises cost, not just consumption. Negative price windows trigger controlled pre- cooling and fresh-air flushing. Price peaks trigger setback within agreed comfort bands.
Day-ahead market integration — read every morning,
applied automatically
Pre-cool / pre-heat into low-price windows; throttle at peaks
Free-cooling and fresh-air flushing scheduled as load-shift events
Demand-response ready: peak-penalty avoidance built in
Live for shopping centres & offices across PL, LT, LV, EE
04 · Dynamic scheduling & airflow
The schedule isn't a setting. It's an outcome the AI calculates every day.
Exergio's dynamic scheduler builds the next day's operating plan from the bottom up — per room controller, per AHU, per heating station — based on actual heating rates, weather, occupancy and the comfort KPI. Static schedules become a thing of the past. Where AHUs have heat-recovery issues, the system rebalances flows automatically and flags the rotor wheel for inspection.
AHU airflow tuned to actual RC heating demand
— 5–20% AHU energy off the top
Heat-recovery faults detected via cross-checked calculation,
not just sensor reading
"Continuous preheat insufficient" → flagged as a hydraulic limit,
not a schedule fix

05 · Virtual Building Assistant
Reception types a sentence.
The AI diagnoses, proposes a fix, asks
before acting.
Technical problems handled through a non-technical interface. A guest complaint becomes a diagnosis, a proposed change, and a resolved ticket — without dispatching a technician. The AI never acts without sign-off. Always asks before acting; always logs the outcome for the ESG report.
Easy for reception, hotel ops, front-desk and non-technical FM
From complaint to resolution in hours, not the next shift
~85% of issues resolved remotely — measured across the Moxy
France & Germany portfolio
Same assistant across every property — centralised, not site-by-site
New for 2027 · available at PoC
Real interaction pattern from a live hospitality deployment. Non-technical staff resolve technical issues in plain English. Nothing changes without staff approval.
06 · ESG, EPC & audit-grade data
The numbers regulators ask for —
pulled from the meter, not the model.
Every signal is logged. Every algorithmic change is timestamped,
attributed and reversible. Reports for CSRD, EPBD, GRESB and
internal ESG committees are generated from real operational data
— not from a separately maintained sustainability spreadsheet that
no one trusts.
Audit-grade ESG / EPBD reporting from real ops data
Verified savings traced to the utility meter — not modelled, not
estimated
Dual-baseline maintained across heat-source transitions (e.g. district
heating → heat pump)
Real-time Energy Performance Contract: continuous M&V, not annual
Replaces and upgrades traditional EPC
Our method
Two stages.
Comfort proven before energy is touched.
A common objection in operations: "We can't change settings — what if it impacts comfort?" Exergio addresses that head-on. We don't activate energy-saving control until comfort is proven stable on the AI's own KPIs. It's how we scale changes safely across cautious operating teams.
Stage 01
Comfort KPI Proofing
Exergio validates comfort stability through data-driven KPIs across every room controller. The operations team sees, in numbers, that comfort holds under proposed changes — before any energy-saving setting is activated. Comfort risks, technical fails, and morning warmup issues are catalogued and tracked.
Output: a comfort scorecard the ops team trusts, plus a remediation plan for the technical fails the system surfaces (sensor errors, actuator stuck, hydraulic limits).
Stage 02
Dynamic Energy Savings
With the comfort floor proven, Exergio activates dynamic control strategies across HVAC systems — dynamic scheduling, dynamic airflow, market-aware operation, free cooling and pre- cooling logic. Measurable savings unlocked without re-opening the comfort debate.
Output: verified energy and € savings against the agreed baseline, reconciled monthly against the Guaranteed Savings Model.
Always supervised
The AI is never alone.
Every building gets a
Dedicated Building Engineer.
Exergio is not a black box you license. Every property under management is assigned a named, best-in-class engineer who watches the system 24/7, validates every algorithmic change, catches drift before clients do, and is the on-call partner for the client team.
You buy a managed performance partner — software plus an engineer, accountable to your numbers.
Reviews every change
Before any new control rule is activated for your building, your engineer signs it off. Every change is reversible with one click.
Catches drift early
The engineer monitors KPI deviations and reaches out before the client sees a regression — not after a complaint lands.
Owns the savings number
Validates monthly savings against the utility meter, reconciles against the Guaranteed Savings Model, and reports to the asset team.
Commercial model
The Guaranteed Savings Model.
Paid for by the savings — not aspiration.
Our recommended commercial model. The annual fee is contractually tied to a minimum kWh and € savings floor. If we miss the floor, the fee recalculates downward by a pre-agreed, symmetric formula. Auditable, reversible, and aligned with the asset owner's economics — exactly the way EPC was always supposed to work.
Pre-agreed, symmetric formula
The savings floor and the fee adjustment are both spelled out in the contract before kick-off. No surprises at year-end. No "expected" or "potential" — only guaranteed and verified.
Verified against the meter
Savings are reconciled monthly against the utility meter and the degree-day-normalised baseline. The same data feeds your ESG/CSRD report — single source of truth.
Replaces and upgrades traditional EPC
Continuous, real-time M&V in place of one-off retrofits and annual reconciliation. Exergio is the real-time performance layer that replaces and upgrades traditional Energy Performance Contracting.
