An ESG data platform for buildings, built on metered and verified data
An ESG data platform for buildings collects the water, energy, carbon and air data that sustainability reports depend on. Aqueduct measures it at the meter every 60 seconds, normalizes it for weather, traces every number to the device that measured it and verifies each saving. Your team or consultant files the report; Aqueduct supplies the evidence.
Report numbers you can trace to a meter, a date and a device.
Water, energy and carbon from the meter, not the invoice
- Continuous data
Consumption refreshes every 60 seconds, so reporting periods close without chasing invoices.
- Carbon from consumption
Electricity converts to carbon with the grid factor, shown with its source and year.
- Data quality visible
Device health and coverage show which figures are complete and which need a note.
Real progress separated from the effects of weather
- Degree-day regression
Baselines use cooling and heating degree days, so a mild season does not count as progress.
- Day-one baseline
Uploading 6 to 12 months of bills gives a baseline from the first week.
- Normalized intensity
Water and energy per square foot and per visitor make sites comparable across a portfolio.
Every claimed saving has a meter reading behind it
- Measured after the fix
Savings are confirmed at the meter against the baseline, not taken from a proposal.
- Stated in money too
Rate configuration from your bills turns verified units into cost, for finance and the board.
- You file, we supply
Your team or consultant files the report; Aqueduct supplies the metered evidence behind it.
Sustainability data, before and after Aqueduct
- Figures are typed in from invoices, months late.
- A mild winter is reported as progress.
- Project savings come from the proposal, not the meter.
- Air quality commitments rest on a spot check.
- Every audit question starts a new spreadsheet hunt.
The Aqueduct way- Figures come from meters, refreshed every 60 seconds.
- Baselines are normalized with heating and cooling degree days.
- Savings are verified at the meter after each fix.
- Air is measured continuously, with exposure in zone-hours.
- Every number traces back to a device and a date.
Why sustainability data is hard to trust
Most ESG numbers start as utility invoices and estimates, months after the fact.
Spreadsheets from invoices
Water and energy figures are typed in from bills, with gaps, estimates and different units across sites.
No weather adjustment
A mild winter looks like progress and a hot summer looks like failure, regardless of what the team did.
Savings you cannot trace
Projects report savings from a proposal, and nobody can show the meter reading behind the figure.
Air quality left out
Healthy building commitments rely on spot checks rather than continuous, occupied-hours data.
What sustainability leads get from Aqueduct
The metrics your reports and certifications need, measured rather than estimated.
Weather-normalized baselines
Regression on usage plus cooling and heating degree days, per site.
Learn moreCarbon from the meter
Electricity converted to carbon with the grid factor, shown daily on the electrical twin.
Learn moreQuestions sustainability leads ask
“Will Aqueduct file our ESG report?”
No. Aqueduct supplies measured, traceable data and verified savings. Your team or your consultant prepares, files and certifies the report.
“Can the numbers be traced back to a device?”
Yes. Every figure rolls up from a meter or sensor in aQ Core, with device health showing connection rate so data quality is visible.
“How do you separate weather from real improvement?”
Baselines are built by regression on usage plus cooling and heating degree days, so a mild season does not count as a saving.
“Can we measure reuse, not just consumption?”
Yes. Where a site has an STP or RO plant, the water twin shows reuse flow, RO recovery and STP efficiency alongside supply.
How Aqueduct shows up in a sustainability lead's month
An illustrative reporting cycle across a portfolio.
Week one
Portfolio performance against baseline shows which sites improved on a weather-normalized basis and which slipped.
Week two
Outlier sites go to the facilities team as findings, with the cost and the carbon attached.
Week three
Verified savings from completed fixes are confirmed at the meter and added to the record.
Week four
The monthly metrics export goes to the reporting workbook, with water, energy, carbon and air data by site.
Features and industries sustainability teams use most
Where the evidence comes from.
Where teams put it to work
Reuse measured alongside consumption
Sites with STP or RO plants see treated flow, recovery and reuse on the same twin as supply, so recycled water is counted from measurement.

Every site on the same basis
A commercial real estate client with a 20M+ sq ft portfolio compares buildings on normalized intensity rather than raw totals.
Learn more
Air quality with occupied hours
CO2, particulates and VOC by zone, with exposure in zone-hours, give healthy building commitments a continuous record rather than an annual test.
Learn moreThe reporting cycle, run from the meter
Sustainability teams spend most of a reporting cycle chasing data. Here is what each stage looks like when the data is already measured, normalized and traceable.
Consumption without the chase
Electricity, water and gas arrive from meters every 60 seconds by site, building and line. Coverage is shown, so gaps are noted rather than filled with guesses.
- Consumption by site, line and feeder
- Device health per meter
- Coverage percentage per site
- Measured
- water, electricity, gas
- Output
- complete or annotated totals
- Aqueduct
- the record, not a reminder email
Weather separated from action
Baselines use regression on cooling and heating degree days, so a mild season is not reported as progress and a hot one is not reported as failure.
- Degree-day baseline per site
- Intensity per square foot and per visitor
- Like-for-like comparison across the portfolio
- Measured
- use against expected
- Output
- progress you can defend
- Aqueduct
- the normalization method on file
Electricity to emissions
Electricity converts to carbon with the grid factor, shown with its source and year. On-site solar and backup generation are separated on the electrical twin.
- Grid factor with source and year
- Grid, solar and backup separated
- Daily carbon on the twin
- Measured
- kWh by source
- Output
- location-based electricity emissions
- Aqueduct
- traceable conversion
Withdrawal, reuse and loss
Stewardship reporting needs more than total consumption. The water twin shows supply by source, reuse flow, RO recovery and unaccounted loss.
- Supply by source where metered
- Reuse measured, not assumed
- Loss as its own line
- Measured
- intake, reuse, loss
- Output
- a water balance
- Aqueduct
- evidence for stewardship claims
Answering the assurance provider
Where disclosures carry assurance, the provider traces how each number was derived. Every figure in Aqueduct rolls up from a device and a date.
- Raw series behind every total
- Method notes for baselines and factors
- Monthly exports by site and period
- Measured
- the full series
- Output
- a derivation the provider can follow
- Aqueduct
- supplies evidence; your provider gives the opinion

Aqueduct supplies the measured data. Your team or consultant maps it to each framework and files.
| Metric | How Aqueduct measures it | Commonly requested by |
|---|---|---|
| Energy consumption | Main and sub-meters, by source | GHG Protocol, CDP, GRESB, BRSR Core |
| Electricity emissions | kWh times grid factor with source and year | GHG Protocol scope 2, CDP |
| Energy use intensity | Per square foot, weather-normalized | ENERGY STAR, NABERS, GRESB |
| Water withdrawal and intensity | Supply meters by source, per square foot | BRSR Core, CDP Water, GRESB |
| Water reuse | Metered reuse flow from STP and RO | Stewardship claims, LEED |
| Verified savings | After-fix use against baseline | ISO 50001 energy performance |
| Indoor air quality | CO2, PM2.5, VOC by zone, zone-hours | WELL, RESET Air |
Scope 1 and Scope 2, built from metered energy
Emissions are activity data multiplied by an emission factor. The activity data is where most inventories are weakest, and it is what Aqueduct measures. Factors are applied with their source and year visible.
Scope 2: purchased electricity
Grid import at the incomer, in kWh, multiplied by a grid emission factor. The GHG Protocol Scope 2 Guidance asks for a location-based figure from average grid factors and, where contractual instruments exist, a market-based figure as well.
- India: CEA CO2 Baseline Database
- United States: EPA eGRID subregion factors
- United Kingdom: government conversion factors
- Activity data
- grid kWh from the incomer meter
- Factor
- configured per site, source and year shown
- Aqueduct
- carbon today on the electrical twin
Rooftop solar
Solar generation consumed on site reduces grid import rather than adding a source of emissions. Metering it separately shows how much of the load it actually covered, hour by hour.
- Solar output metered as its own source
- Grid import net of solar
- Self consumption reported separately
- Activity data
- solar kWh generated and used
- Effect
- lower grid import
- Aqueduct
- grid, solar and backup in one balance
Scope 1: generator fuel
Diesel burned in backup generators is a direct emission. Generator output is metered on the twin; fuel volumes come from fuel logs or flow meters where fitted, and the factor is applied to fuel, not to kWh.
- Generator run hours and output recorded
- Fuel volume from logs or meters
- Output per litre as a plausibility check
- Activity data
- fuel volume, supported by generator output
- Factor
- fuel combustion factor from your chosen source
- Aqueduct
- run records that support the fuel figure
Scope 1: natural gas
Gas for boilers, kitchens and process heat is metered in cubic meters and therms, so both volume and energy content are available. The emission factor is applied to energy content.
- Gas in cubic meters and therms
- Heating use against heating degree days
- Boiler efficiency questions raised from the trend
- Activity data
- gas energy content
- Factor
- per your reporting method
- Aqueduct
- weather-normalized gas baseline
Scope 1: refrigerant leakage
Refrigerant losses are a direct emission but are not metered by Aqueduct. They come from service records of refrigerant added. Rising compressor energy at the same cooling, or a short-cycling rack, can prompt a leak check sooner.
- Quantities from service records
- Plant performance trends as an early prompt
- Kept outside the metered figures, and labeled so
- Activity data
- refrigerant charged, from service logs
- Limit
- not a metered quantity
- Aqueduct
- plant data that prompts a check
Where each sustainability metric comes from
For each figure, the calculation, the data behind it and what an assurance provider can trace.
| Metric | Calculation | Source in Aqueduct | Trace available |
|---|---|---|---|
| Scope 2, location-based | Grid kWh times grid factor | Incomer meter, factor with source and year | Interval data per meter, factor reference |
| Scope 1, gas | Gas energy times combustion factor | Gas meters in therms or cubic meters | Meter series and unit conversion |
| Scope 1, diesel | Fuel volume times combustion factor | Generator output and run records, fuel logs | Run records against fuel quantities |
| Energy use intensity | Total energy divided by floor area | Electrical twin, site area | Meters, coverage and area used |
| Water intensity | Intake divided by floor area or visitors | Water twin, site area, visitor counts | Intake meters by source |
| Water withdrawal by source | Sum of metered intake per source | Main supply and source meters | Meter series per source |
| Water reuse | Sum of metered reuse lines | STP, RO and reclaimed water meters | Reuse meters and destinations |
| Verified savings | Adjusted baseline minus actual | Weather-normalized regression per site | Baseline method, degree days, actuals |
| Data coverage | Metered share of floor area and time | Device health and sub-metering coverage | Per device connection history |
How the energy balance supports assured data
Totals reconcile
On the electrical twin, sources must equal loads plus losses. A total that reconciles at every level is a total an assurance provider can follow from the incomer down to the feeder.
Gaps are shown, not filled
Sub-metering coverage and device health show which meters and periods are missing. Gaps are noted openly, so estimates are labeled as estimates rather than hidden inside a measured total.
BRSR Core
SEBI requires the largest listed companies to obtain reasonable assurance on BRSR Core, which includes energy and water intensity. The provider traces each figure to source; Aqueduct supplies the series behind it.
CSRD
Under the EU Corporate Sustainability Reporting Directive, sustainability information is reported against the ESRS and is subject to assurance. Metered energy and water by site give the environmental datapoints a measured basis.
GRESB
GRESB evaluates data coverage by both floor area and time. Device level coverage in Aqueduct shows both, per asset, before the submission is built.
From utility bills to assured reporting
Most sustainability teams start with what they already have, their bills, and move to metered data site by site.
Bills in
Six to twelve months of electricity, gas and water bills are uploaded per site. Baselines and rate configuration come from them, so performance against a weather-normalized baseline shows from day one.
Main meters live
Incomer meters for electricity, gas and water report every 60 seconds. Bills are now checked against the meters, and usage changes are separated from rate changes.
Sub-metering and twins
Sources, feeders and water consumers are sub-metered where it matters. The energy and water balances close, coverage is known, and emission factors are configured per site with source and year.
Metered disclosures
Monthly exports by site carry the series, the factors and the baseline method. Your team or consultant maps them to the framework and files.
Answering the provider
The provider samples figures and traces them to devices and dates. Aqueduct supplies the evidence; the provider forms the opinion.
Four plant questions every sustainability lead should ask
Is the main incomer metered, and does it reconcile?
If the sum of feeders does not match the incomer, every intensity figure inherits the error.
Learn moreWhich loads are unmetered?
Unmetered load is indistinguishable from loss. Coverage should be known before targets are set.
How is weather handled?
A target met in a mild year is not progress. Degree day baselines separate weather from action.
Learn moreWhere does reuse get measured?
A reuse figure from a plant's rated capacity is a design number. Reuse lines need meters.

Common questions
It is a system that collects the environmental data behind sustainability reporting, such as water, energy, carbon and air, from the buildings themselves. Aqueduct measures this data at the meter, normalizes it for weather and verifies savings, then supplies it for the reports your team files.
No. Aqueduct supplies the measured metrics, verified savings and exports. Your sustainability team or consultant prepares, files and certifies the report against the framework you use.
Electricity consumption from the meters is multiplied by the grid carbon factor, which is shown with its source and year on the electrical twin. Gas is tracked in therms or cubic meters for the same purpose.
Weather drives heating, cooling and some water use. Aqueduct builds baselines by regression on usage plus cooling and heating degree days, so reported improvement reflects what the team did rather than a mild season.
Aqueduct supplies the measured water, energy and air evidence that certifications ask for. The certification itself is applied for and awarded through your team or consultant; Aqueduct does not certify buildings.
Uploading 6 to 12 months of utility bills gives Aqueduct a day-one baseline, so performance against baseline is available from the start rather than after months of monitoring.
Results depend on each site's starting point. Energy and water savings are measured against a weather-normalized baseline and verified at the meter, so each figure is reported, not estimated.
Aqueduct keeps the raw series behind every total, the baseline method and the emission factors used, so an assurance provider can follow the derivation. The provider forms the opinion; Aqueduct supplies the evidence.
Device health and coverage show exactly which meters and days are incomplete. Gaps are flagged so your team can note or estimate them openly rather than hide them in a total.
Yes, where reuse lines are metered. The water twin carries reuse flow, RO recovery and STP efficiency alongside supply and unaccounted loss.
The factor configured for each site, displayed with its source and year. Your team chooses the factor that matches its reporting method.
Aqueduct supplies the metered kWh by site and period. A market-based figure also needs your contractual instruments, such as certificates or supplier specific factors, which your team applies under the GHG Protocol Scope 2 Guidance.
Generator output and run hours are recorded on the electrical twin. The emission is calculated from fuel burned, so fuel volumes come from logs or fuel meters, with generator output as a check on them.
Not from meters. Refrigerant leakage comes from service records of refrigerant added. Plant performance trends in Aqueduct can prompt an earlier leak check.
The area your reporting framework defines. Aqueduct applies the area configured for each site and shows it alongside the intensity, so the denominator is never hidden.
It shows device level coverage by time and the metered share of each site, which are the inputs to GRESB coverage by area and time. Your team completes the submission.
