Loaded from a public authority and shown with its date and spatial resolution.
Every figure should be verifiable.
TrustHuus keeps official data, modelled values, publicly evidenced statements, verified information and unknown fields separate. V1 does not create an opaque score or treat missing data as a positive result.
Calculated on a geographical grid; not a measurement inside the building.
Remains explicitly unknown. TrustHuus does not fill gaps with assumptions.
