Data centers where cooling, power and water are one picture.
Halls, chiller yards and electrical rooms, each watched by a different tool. Aqueduct puts power, cooling and water on one measured record, so PUE and WUE trace to meters.
What data centers teams are up against.
Water, energy, air and operations carry equal weight. Each one runs the same loop: monitor, measure, identify, act, verify.
Water: Cooling towers and humidification
Make-up and blowdown unmetered, so WUE is an estimate
Energy: Chillers, CRAHs and the electrical chain
Conservative setpoints and lightly loaded UPS
Air: Rack inlets
Hot spots between the few sensors the BMS reads
Operations: Cooling plant
A fouled coil showing first as one warm aisle
Problem, solution, impact.
How Aqueduct resolves each problem for data centers, and what changes when it does.
Make-up and blowdown unmetered, so WUE is an estimate
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.
Conservative setpoints and lightly loaded UPS
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.
Hot spots between the few sensors the BMS reads
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.
A fouled coil showing first as one warm aisle
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, from first signal to verified fix.

Replace what should be replaced. Connect the rest.
- BMS
- Power monitoring
- Cooling tower monitoring
- DCIM
- CMMS
- Electrical power monitoring systems
Three equal ways in: keep your BMS, replace it, or build Aqueduct in at design stage.
The questions each seat asks first.
“Will it warn me before a cooling fault becomes an incident?”
“Are PUE and WUE measured or estimated?”
“Can it be specified into the next hall?”
Standards and regulations we supply evidence for.

EU reporting
Sites with 500 kW of IT or more report energy, setpoints, waste heat and water every year after a first report in September 2024.
Overhead grows with load
With average PUE flat, cooling and electrical losses rise with every new hall unless they are measured and tuned.

Common questions
No. Aqueduct starts read only on one hall, taking BMS, EPMS and meter data without writing back. Any later control change goes through your change management process with owner approval, and every command is kept in an auditable history.
WUE is site water use divided by IT energy, as defined in ISO/IEC 30134-9. Aqueduct sums metered cooling tower make-up, humidification and domestic water, divides by metered IT energy and trends the ratio by month, so a change in cooling mode shows up. See WUE.
Measured. Aqueduct calculates PUE from total facility energy and IT energy at the meters, per hall and per interval, following ISO/IEC 30134-2. Where a hall lacks an IT meter, the gap is shown rather than filled with an estimate. See PUE.
Aqueduct supplies the metered energy, water and temperature data that EU Regulation 2024/1364 asks larger sites to report by 15 May. Your team files the report, and Aqueduct keeps the interval history and exports for the reporting year.
Yes. Aqueduct checks CRAH, chiller and pump states against their sequence and flags drift such as rising supply temperature or a pump drawing more power for the same flow. The alert reaches the critical facilities team with the asset and likely cause before inlet temperatures leave range.
