Building compliance software that supplies the measured evidence every program asks for
Building compliance software collects the measured data that energy, water and air standards ask for. Aqueduct meters energy, water and indoor air by site, floor and zone, builds weather-normalized baselines, verifies savings at the meter and exports the numbers for ISO 50001, LEED, WELL, Local Law 97, GRESB and CSRD. Your team or consultant files and certifies.

One measured dataset behind every standard, rating and filing your buildings face.
Evidence collected every day, not gathered at the deadline
- Live meters
Energy, water and gas meters report on a 60-second refresh, so consumption is known by site, floor and line.
- Air per zone
CO2, particulates, VOCs, temperature and humidity are recorded per zone, with exposure tracked in zone-hours.
- Device health
Connection rate and battery voltage per device show where data is trustworthy before it goes into a report.

Weather-normalized baselines a reviewer can follow
- Degree day regression
Usage is modeled against cooling and heating degree days, so a mild year does not pass for a saving.
- Day-one start
Uploading 6 to 12 months of utility bills gives a baseline before the first live month closes.
- Savings in money
Rate configuration from your bills turns the difference from baseline into cost, per site and per period.

Verified results, ready for the people who file
- Verified at the meter
A saving counts only after the meter confirms it, and every verified result becomes the new baseline.
- Exports by period
Totals by site, fuel, month and zone export cleanly for consultants, investors and city portals.
- Audit trail kept
Command history and fault closures show what was done and when, which reviewers increasingly ask for.

Compliance reporting, before and after Aqueduct
- Bills are chased across sites weeks before every deadline.
- Each standard gets its own spreadsheet and its own numbers.
- A warm year hides waste and a cold one hides savings.
- Air quality is sampled once and assumed the rest of the year.
- Nobody can show the claimed saving actually happened.
The Aqueduct way- Metered data is collected every day and ready before the deadline.
- One measured dataset feeds every standard, rating and filing.
- Weather-normalized baselines show real change in any year.
- Air is recorded per zone continuously, with exposure in zone-hours.
- The meter verifies each saving before anyone reports it.

Every standard on this page asks the same thing in a different format: show what the building used, show what changed, and show that the change was real. Most teams answer with bills gathered at the deadline, spreadsheets and a site walk. Aqueduct answers with meters, sensors and equipment data collected all year on one data layer.
Aqueduct is not a certification body, an auditor or a filing service. It supplies the measured inputs, the baselines and the verified results. The owner, the energy manager or the consultant still runs the management system, prepares the submission and signs it.

The same six evidence problems sit under every standard
Select a topic to see where evidence usually breaks, what gets measured and which pages cover it.
Energy performance
Bills arrive late and cover odd periods, and nobody can say which system used what. Baselines ignore weather, so progress looks like luck.
Main and sub-meters by fuel, feeder and major equipment, plus weather per site.
Weather-normalized baselines, EnPIs and verified savings. Pages: /compliance/iso-50001, /compliance/ashrae-90-1, /compliance/energy-star-portfolio-manager, /compliance/esos, /compliance/nabers, /compliance/bee-pat-and-ecbc, /compliance/eu-epbd/.
Building performance laws
Owners find out they missed a limit after the year closes, when nothing can be done.
Energy by fuel per building, monthly, against the limit for the year.
Year-to-date tracking against each limit, with the gap acted on early. Pages: /compliance/local-law-97, /compliance/building-performance-standards, /compliance/eu-epbd/.
Water use and loss
Leaks and unmetered uses hide inside a single utility bill, and water audits rely on estimates.
Main and sub-meters by source and use, pressure and level, with night flow.
A live water balance and leak alerts. Pages: /compliance/awwa-m36-water-audit, /compliance/leed, /compliance/breeam, /compliance/dubai-al-safat, /compliance/estidama-pearl/.
Water safety
Temperature drift and stagnant branches go unseen between manual rounds.
Water temperature and flow at instrumented control points and low-use branches.
Continuous control point records with excursions closed. Pages: /compliance/ashrae-188-water-management, /compliance/legionella-hsg274-l8, /compliance/joint-commission-environment-of-care/.
Indoor air and ventilation
Spot checks show a good day, while pressure reversals and CO2 build-up happen when nobody looks.
CO2, temperature, humidity, particulates, VOCs and room pressure per zone.
Per-zone records against each space's limit. Pages: /compliance/ashrae-62-1, /compliance/ashrae-170, /compliance/well, /compliance/nabh, /compliance/joint-commission-environment-of-care/.
Carbon and disclosure
Year-end spreadsheets mix estimates with bills, and assurance providers cannot trace totals to source.
Fuel and electricity by site, water by source, with factors and estimates flagged.
Measured activity data with a meter-to-total trail. Pages: /compliance/ghg-protocol-scope-1-and-2, /compliance/secr, /compliance/csrd, /compliance/cdp-climate-and-water, /compliance/brsr-core, /compliance/gresb, /compliance/iso-14001/.
From scattered records to audit-ready evidence across a portfolio
The order is the same whatever the standard: map obligations, connect what exists, fill gaps, then run the year on live data.
Map obligations to sites
List each site's standards and filings with their deadlines, then list the data each one needs. Upload 6 to 12 months of bills for a day-one baseline.
Connect existing meters and the BMS
Read utility meters, sub-meters and BMS points over BACnet, Modbus, M-Bus or pulse outputs. aQ Atria tags each new device to its site, floor and zone.
Fill the evidence gaps
Add wireless meters and sensors where a standard asks for data you cannot produce, such as tenant splits, room pressure or water temperature at control points.
Run the year on live data
Excursions and faults are flagged and closed as they happen. Each filing draws on the same measured record, exported with its trail.
Which measurements serve which standards
One device often serves several standards. This is the usual starting kit.
| Measurement | Typical device or source | Standards it serves |
|---|---|---|
| Electricity by building and feeder | Utility meter, CT-based sub-meters, BMS power points | ISO 50001, ASHRAE 90.1, Portfolio Manager, LL97, NABERS, ESOS, SECR, PAT |
| Gas and other fuels | Gas meters with pulse outputs, fuel flow meters, generator meters | GHG Protocol Scope 1, LL97, SECR, BRSR Core, CDP |
| District heating and cooling | Thermal energy meters over M-Bus or Modbus | Al Sa'fat, Estidama Pearl, GHG Protocol Scope 2, EPBD |
| Water by source and use | Main and sub-meters, borewell and tanker meters | AWWA M36, LEED, BREEAM, BRSR Core, CDP, CSRD |
| Water temperature and flow at control points | Pipe temperature sensors, branch flow meters | ASHRAE 188, L8 and HSG274, Joint Commission EC |
| CO2, temperature and humidity per zone | AirSafe sensors or BMS points | ASHRAE 62.1, WELL, LEED, NABH, EPBD |
| Room pressure and airflow | Room pressure monitors and BMS airflow points | ASHRAE 170, Joint Commission EC, NABH |
| Particulates and VOCs | Multi-parameter air quality sensors | WELL, LEED, NABH |
| Weather and occupancy | Weather data per site, PIR and occupancy sensors | Every weather-normalized baseline and EnPI |

Common questions
Building compliance software collects and organizes the data that energy, water and air standards require. Aqueduct does this from live meters and sensors rather than bills gathered at the deadline, and adds weather-normalized baselines and savings verified at the meter. The owner or consultant still prepares and files the submission.
No. Aqueduct supplies measured evidence, baselines and verified results, and helps teams act on the gap. Compliance, certification and filing stay with the owner, their consultant and the certifying body or authority.
Aqueduct supplies data for ISO 50001, ASHRAE 62.1 and 90.1, LEED, WELL, BREEAM, ENERGY STAR Portfolio Manager, Local Law 97 and other building performance standards, GRESB, CSRD, AWWA M36 water audits, Dubai Al Sa'fat and NABH. The same metered dataset feeds each one.
Energy compliance reporting is the recurring submission of energy use, emissions or performance data to a city, regulator, investor or certification program. Aqueduct keeps that data measured all year by site and fuel, so the report is an export rather than a scramble.
Yes. Aqueduct can build a day-one baseline from 6 to 12 months of utility bills, then track performance against it as live meter data arrives.
No. Aqueduct is the measured data behind the consultant's work. Consultants spend less time chasing bills and more time on strategy, submissions and the projects that close the gap.
Aqueduct measures water, energy and indoor air with equal weight. Water balances, zone-level CO2 and particulates, and energy by fuel all sit on the same platform, which matters for LEED, WELL, BREEAM and water audits.
Start with the market view on this page, then add the topic standards your investors and customers ask for, such as GRESB, CDP or CSRD. One measured dataset in aQ Core feeds all of them, so each site is metered once.
Usually not. Most standards share the same measurements, and existing utility meters, sub-meters and BMS points can be read. New devices go where a standard asks for something nobody measures today.
Readings are stored at interval level, so the same data can be totaled by calendar year, financial year or a rating period such as NABERS's 12 months, without re-collecting anything.
We describe each standard as accurately as we can, but standards, thresholds and deadlines change. Always check the current edition and your local rules, and confirm with your consultant or assessor.
Always your team, your consultant, your assessor or the authority. Aqueduct supplies measured evidence; it never certifies, accredits or files on your behalf.
