Standards and regulations

The measured data behind 28 building standards and regulations

Each page below covers one standard: who it applies to, what it requires and which meter or sensor readings prove it. Aqueduct supplies those readings through aQ Assure. Your team, assessor or consultant files and certifies.

Demo data

How does this week compare to the last few weeks?

12% below last week, driven by lower HVAC load on weekday afternoons. Two days had low meter coverage.

Questions

Common questions

No. It supplies continuous measured data, flags readings outside the limits you set and exports records for the period under review. Certification bodies, assessors, regulators and registered professionals decide compliance.

Start with the one that carries a date or a penalty where you operate, such as Local Law 97 in New York, ESOS in the UK or BRSR Core in India. The same meters then serve the voluntary ratings.

aQ Assure is the Aqueduct module that turns meter and sensor data into compliance evidence. It stores each limit against the points that test it, flags readings outside range and exports records by period for an assessor or regulator, using the same aQ Core data as operations.

Yes. A sub-meter on a chiller feeds ISO 50001 indicators, ASHRAE 90.1 end-use reporting, a LEED prerequisite and a GHG inventory at the same time. Aqueduct keeps one metered record per site and exports it in the shape each program asks for, so data is collected once.
