Compliance built on connected data.
MESTRA brings the data from all your building systems together into one reliable source of truth — measurable, verifiable and directly usable for ESG reporting, GACS compliance and BREEAM certification.
High ambitions.
Fragmented data.
Sustainability ambitions have never been higher. Yet many buildings still rely on manual data collection, disconnected meters and spreadsheets to prove performance. The result: time-consuming reporting, unreliable data and performance that is hard to demonstrate and verify.
Manual Reporting
Data gathered by hand across siloed systems
Unreliable Evidence
Gaps and estimates undermine every claim
Rising Regulation
GACS, EPBD and ESG demands grow each year
Certification Pressure
BREEAM requires continuous, verifiable data
No Single Source
Performance scattered across every system
Greenwashing Risk
Claims without data erode trust and value
From fragmented data
to demonstrable performance.
MESTRA brings your existing building systems together into one intelligent layer and continuously captures current data on energy use, occupancy and building performance. This way sustainability goals become not only measurable, but also demonstrable and verifiable.
