Airports

Airports where every meter point reports, and every loss gets fixed.

Terminals, concourses, cargo and landside on one platform. Thousands of meter points become a live balance, and an anomaly becomes a ticket and a verified saving.

Thousands of meter points become one live balance, and every loss gets an address.

Terminal water balance

Terminal, tenant and airfield water reconciled every minute

  • One live balance

    Main supply is reconciled against terminals, tenants, cooling and airfield use, with telemetry refreshed every 60 seconds.

  • Loss with a location

    Unaccounted water is localized to a riser or a zone, so the crew walks to one place, not everywhere.

  • Proven at scale

    Water savings are verified at the meter against a weather-normalized baseline. Every loss is read from one live balance.

Schedule-aware energy

Peaks that follow the flight schedule, not the clock

  • Weather and schedule baselines

    Baggage halls, chillers and jet bridges are baselined against weather and the flight schedule, not a flat average.

  • Peaks shifted

    Where control is enabled, with owner approval, loads are sequenced so peaks drop, and every command is logged.

  • Concourse air

    Fresh air follows passenger occupancy by zone, and the energy cost of that air is counted alongside it.

Tenant billing

Concessions billed on what they actually used

  • Sub-meters reconciled

    Tenant sub-meters reconcile to the main meter, so gaps between billed and metered use show up quickly.

  • Bills validated

    Utility bills are checked against metered use, so overcharges and estimated reads are caught before payment.

  • Records for disputes

    Concession charges rest on measured interval data, so a tenant query is answered with a chart, not a debate.

Old way vs the Aqueduct way

Running an airport, before and after Aqueduct

The old way
  • The quarterly water bill is the first sign of a leak.
  • Thousands of meters report into systems nobody reconciles.
  • Chillers run the same profile on quiet days and peak days.
  • Tenant water charges are estimated from floor area.
  • A leak ticket closes when the crew says it is fixed.
The Aqueduct way
  • The live water balance flags the loss within days, with an address.
  • Every meter point reconciles into one balance for the whole airport.
  • Plant follows the flight schedule, and peaks are shifted with approval.
  • Tenant charges rest on reconciled sub-meter data.
  • A leak ticket closes when the balance confirms the loss stopped.
Problems by outcome

What airports teams are up against.

Water, energy, air and operations carry equal weight. Each one runs the same loop: monitor, measure, identify, act, verify.

01

Water: Every meter point, one balance

Terminal, tenant and airfield water reconciled, so a loss has an address within days, not at the quarterly bill.

02

Energy: Peaks that follow the schedule

Baggage halls, chillers and jet bridges baselined against weather and flight schedule. Peaks shifted, with the command logged.

03

Air: Terminal air that follows passengers

Fresh air follows occupancy by zone. The energy cost of that air is counted.

04

Operations: Tenants billed on what they used

Sub-meters reconcile to the main meter. Concession billing rests on measured use.

How Aqueduct resolves each problem for airports, and what changes when it does.

The problemHow Aqueduct solves itThe impact
Water

Terminal, tenant and airfield water reconciled, so a loss has an address within days, not at the quarterly bill.

A live water balance across meters and sub-meters localizes the loss, routes the fix and confirms it closed at the meter.

Loss found from the balance, not the bill, and every fix verified.

Energy

Baggage halls, chillers and jet bridges baselined against weather and flight schedule. Peaks shifted, with the command logged.

Weather-normalized baselines per building and asset show the waste in money; schedules and setpoints adjust where control is enabled.

Savings stated in money and confirmed at the meter, not estimated.

Air

Fresh air follows occupancy by zone. The energy cost of that air is counted.

Air quality per zone, overlaid with occupancy, with ventilation raised when it matters and verified back in range.

Targets held during occupied hours, with the energy cost counted.

Operations

Sub-meters reconcile to the main meter. Concession billing rests on measured use.

Faults diagnosed in plain language and routed into your CMMS with the fix; early signs of failure schedule maintenance first.

Fewer reactive call-outs and closures confirmed by the equipment.

One incident, start to finish

Airport systems

Where water and energy go in an airport, and where they leak

An airport is a small city that never closes. These are the systems that carry most of the load and most of the hidden loss.

Central utility plant

Where it goes wrong

Chillers and boilers staged for peak traffic all day, and cooling towers cycling far more water than they need.

What we measure

Plant energy, chilled and hot water flows, tower make-up and blowdown.

What Aqueduct does

Baselines the plant against weather and the flight schedule, and reconciles each tower.

Terminal air handling

Where it goes wrong

Large volumes conditioned at full fresh air rate whether a gate is boarding or empty.

What we measure

AHU energy and run hours, zone CO2, temperature and humidity.

What Aqueduct does

Shows where ventilation could follow passenger load, and counts the energy of the air delivered.

Baggage handling

Where it goes wrong

Conveyors and sortation running between banks of flights with no bags on the belt.

What we measure

Feeder level energy per baggage zone.

What Aqueduct does

Compares belt energy with the flight bank schedule and flags idle running.

Gates and jet bridges

Where it goes wrong

Preconditioned air and ground power left on after the aircraft has gone.

What we measure

Energy per gate on PCA and ground power supplies.

What Aqueduct does

Flags gates drawing power with no aircraft on stand, using the schedule feed where provided.

Restrooms and potable water

Where it goes wrong

Running fixtures, failed flush valves and riser leaks in high-traffic restrooms.

What we measure

Riser and restroom sub-meters, with occupancy where fitted.

What Aqueduct does

Keeps a terminal water balance so a running fixture is localized to a riser.

Concessions and tenants

Where it goes wrong

Tenant use estimated from floor area, so the airport carries the difference.

What we measure

Tenant electricity and water sub-meters.

What Aqueduct does

Reconciles tenant meters to the main and exports measured use for billing.

Parking structures

Where it goes wrong

Garage ventilation and lighting at full output around the clock.

What we measure

Fan and lighting energy, with CO sensors where installed.

What Aqueduct does

Finds full-output running at low traffic and, where control is enabled, with owner approval, sets schedules.

Landside and irrigation

Where it goes wrong

Irrigation on fixed timers and underground mains that leak for months.

What we measure

Irrigation and landside sub-meters with weather.

What Aqueduct does

Flags watering through rain and night flow that never drops.

Who reads it

One airport, six teams that need the same numbers

Airports split responsibility across departments that rarely share data. A single measured record gives each team what it needs without a separate project.

01 / 06

Facilities and engineering

The team keeps plant running across terminals built in different decades, often with different BMS vendors. Aqueduct reads them side by side.

  • One view across mixed BMS generations
  • Faults routed into the CMMS with the likely cause
  • Plant drift ranked so capital goes where it pays
Measured
plant energy, flows, zone conditions
Target
design performance per system
Aqueduct
fault detection, diagnosis and verified closure
02 / 06

Sustainability and carbon

Carbon accreditation and annual reporting need scope 1 and 2 numbers that trace to a meter. Aqueduct supplies measured use per terminal and per fuel.

  • Electricity, gas and diesel per terminal and system
  • Weather-normalized trends for year on year claims
  • Exports for the carbon footprint and reduction plan
Measured
energy by fuel, by building
Target
the airport's reduction targets
Aqueduct
supplies the evidence, the accreditation body assesses it
03 / 06

Commercial and concessions

Concession utility charges based on floor area leave the airport exposed. Measured tenant use makes the charge defensible.

  • Tenant sub-meters reconciled to the main
  • Interval data behind every charge
  • Disputes answered with a chart
Measured
tenant electricity and water
Target
full recovery of tenant use
Aqueduct
exports measured use to your billing system
04 / 06

Airport operations center

The operations center needs to know when a utility problem will affect passengers. Aqueduct raises alerts by location and severity, without touching operational systems.

  • Alerts for restrooms, gates and concourses by location
  • Conditions in passenger areas visible live
  • Airport operational systems stay separate
Measured
zone air, water and power events
Target
no passenger-facing failures
Aqueduct
location-based alerts with a ticket attached
05 / 06

Finance

Utility bills for a large airport are complex, with many accounts and tariffs. Bills are checked against metered use before payment.

  • Bills validated against meters
  • Savings stated in money through rate configuration
  • Budget forecasts on weather-normalized use
Measured
utility consumption and demand
Target
pay only for what was used

Tenants and airlines

Airlines and concessionaires increasingly ask for their own use data. A shared measured record means one set of numbers for everyone.

  • Tenant level reports on request
  • Same data the airport bills from
  • Supports tenant sustainability reporting

Carbon accreditation

What each Airport Carbon Accreditation level asks of your data

Accreditation is assessed by the program and its verifiers. Aqueduct supplies measured energy evidence; it does not accredit anyone.

LevelFocusWhat measured data supports
1 MappingA carbon footprint for emissions the airport controlsScope 1 and 2 energy use by fuel and building, traced to meters
2 ReductionTargets and shown reductions against themWeather-normalized trends that separate real reduction from a mild year
3 OptimizationEngaging airlines, tenants and service providersTenant and concession use measured and shared
3+ NeutralityOffsetting residual scope 1 and 2 emissionsA defensible residual, based on measured use rather than estimates
4 and 4+ Transformation and TransitionAbsolute reductions aligned with climate goalsSystem level evidence for where reductions came from, verified at the meter

How it rolls out

Terminal by terminal, without disrupting the airfield

Airports cannot shut a concourse to install meters. The rollout follows access windows and starts where existing meters already report.

1
Weeks 1 to 2

Read what already exists

Connect to the BMS, existing utility meters and any historian. Most airports have thousands of points that report into systems nobody reconciles.

2
Weeks 3 to 6

First balance and baselines

A water balance and energy baseline per terminal, normalized for weather and, where a schedule feed is available, for flight activity. The first losses usually appear here.

3
Weeks 6 to 12

Fill the gaps

Add sub-meters and air sensors where the balance does not close, installed with Atria during night access windows. Wireless devices avoid new cable routes airside.

4
Months 3 to 6

Act and verify

Findings routed to the CMMS, tenant billing on measured use, and where control is enabled, with owner approval, schedules applied to gates, garages and AHUs.

5
Ongoing

Extend and report

Further terminals, cargo and landside added on the same model. Carbon and water reporting runs from the measured record.

Old and new terminals

Keep, replace or build in

Keep

Older terminals keep their BMS and meters. Aqueduct reads them over BACnet, Modbus and vendor APIs and puts them on the same model as newer buildings.

Learn more

Replace

Where meters or controls have failed, Aqueduct supplies replacements and brings them online with the rest.

Learn more

Build in

New terminals and expansions specify the measurement layer at design, so the building starts with a baseline.

Learn more

Verify

Every saving is verified at the meter against a weather-normalized baseline, then stated in money through rate configuration.

Questions

Common questions

When the balance stops closing, the loss is flagged with a location, instead of waiting for the bill. Every saving is verified at the meter against a weather-normalized baseline.

Yes. Keep, replace or build in: Aqueduct works with what is installed, replaces what is failing, or is specified into a new terminal.

It supplies the measured use per tenant and exports it. Your billing system issues the bills.

Instead of relying on a site-wide quiet period, Aqueduct keeps balances per terminal and riser and compares each with its own baseline for the same time and traffic. A riser whose low point keeps rising stands out even while the terminal is busy.

Yes, where the airport provides a schedule feed. It is used to explain load and to normalize baselines. Aqueduct does not write to airport operational systems.

Installs follow the airport's access and escort rules, usually in night windows. Wireless LoRaWAN devices and clip-on meters reduce the need for new cable routes, and Atria confirms each device is reporting before the crew leaves.

Where those supplies are metered, yes. They become named terms in the terminal water balance, so they are not confused with loss.

It supplies measured scope 1 and 2 energy data by fuel and building, and weather-normalized trends. Accreditation itself is assessed by the program and its verifiers.
