Design practices that see how their buildings actually perform.
Architects, MEP engineers and sustainability consultants specify a measurement layer, then compare the model with measured use system by system. Post occupancy evaluation runs on data, not a survey.
What design and architecture teams are up against.
Water, energy, air and operations carry equal weight. Each one runs the same loop: monitor, measure, identify, act, verify.
Water: Domestic water and towers
Leaks and tower make-up counted as demand
Energy: Central plant at part load
Rated efficiency in the model, fouled coils in the building
Air: Ventilation
Design airflow delivered to half empty zones
Operations: Schedules and setpoints
Commissioning settings nobody checks against the model
Problem, solution, impact.
How Aqueduct resolves each problem for design and architecture, and what changes when it does.
Leaks and tower make-up counted as demand
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.
Rated efficiency in the model, fouled coils in the building
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.
Design airflow delivered to half empty zones
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.
Commissioning settings nobody checks against the model
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.
An illustrative example of the flywheel on a typical site.
Meter schedule specified at design, mapped to model zones.
Commissioned with the BMS. First season baseline.
East wing heating well above the model.
Traced to overlapping deadbands, sent to FM.
Fixed in aftercare. Assumption corrected for the next model.
Four connected products on one data layer.
Replace what should be replaced. Connect the rest.
- Occupant surveys as the only POE
- Design-stage rating used as the only evidence
- Ad hoc data requests to owners
- BMS through BACnet and Modbus
- Energy model outputs for comparison
- Owner and FM reporting
Three equal ways in: keep your BMS, replace it, or build Aqueduct in at design stage.
The questions each seat asks first.
“Can we prove our buildings perform, not just certify?”
“Which of my modeling assumptions were wrong, and by how much?”
“Can post occupancy evaluation carry measured data instead of a survey?”
Standards and regulations we supply evidence for.
We supply the measured inputs. You run the program and file the report.
A metering specification that survives procurement.
| Line | What to specify | What it tests later |
|---|---|---|
| Main incomers | Revenue grade, over Modbus or BACnet | Whole building use for benchmarking |
| HVAC plant | Chillers, heat pumps or boilers, pumps, major AHUs | Locates a gap to the plant |
| Lighting and small power | Boards per floor or tenancy | Tests plug load assumptions |
| Water | Cooling make-up, irrigation, kitchens, risers | Closes a water balance |

The points already exist
Practices that map code required meters to model zones get post occupancy comparison with no extra hardware.
Ratings in operation
UK lets over 1,000 square meters move to EPC B, and owners will ask design teams to show performance.

Common questions
No. Any model that predicts use at system level can be compared with metered data, and the comparison sharpens as months of operating data come in. Gaps between design intent and actual use show up per system rather than as one building total.
Yes, as far as the owner allows. Data rights are agreed in the specification, so measured energy and water results can support case studies, award entries or post-occupancy reports with the owner's consent.
At design stage, alongside the MEP engineers, so meters, sensors and BMS points are planned once instead of retrofitted. See build it in for how Aqueduct is specified into new construction.
