Bygningsinformasjon

Bygningsinformasjon is the collection of data describing a building's physical and functional characteristics throughout its lifecycle. It encompasses information used to plan, design, construct, operate, and renovate buildings, including location, legal identifiers, architectural and structural properties, technical systems, energy performance, safety features, and maintenance records.

Typical data categories include identification (address, cadastral data), physical properties (dimensions, materials, construction details), systems (HVAC, electrical, plumbing), performance data (energy use, thermal performance), safety and compliance (fire protection, accessibility, inspections), and documentation (drawings, manuals, warranties, permits). The information may exist as structured models, documents, and databases, and is often linked across disciplines to support coordinated workflows.

Data are usually stored in digital formats, commonly within a Building Information Model (BIM) or asset management system, and can be integrated with geographic information systems (GIS). Interoperability relies on standards such as the Industry Foundation Classes (IFC) and the ISO 19650 series, which guide information requirements, organization, and delivery throughout a project’s lifecycle.

Applications of bygningsinformasjon include design coordination, construction planning, facility management, maintenance scheduling, asset lifecycle analysis, and regulatory compliance. Governance aspects cover data ownership, access rights, data quality, version control, and privacy considerations, with responsibilities defined for owners, operators, and contractors.

Bygningsinformasjon is a central concept in modern digital building practice and is closely tied to BIM and digital twins, supporting transparent, data-driven decision making in the built environment. See also BIM, IFC, ISO 19650, and digital twin concepts.
