TS EN 15221-1

TS EN 15221-1 is a terminology standard for facility management, providing the core terms and definitions used in this field. It establishes a shared vocabulary for facility management so that concepts linked to buildings, services, organisation, and resource handling are understood consistently across disciplines. Its value lies in terminology alignment rather than in prescribing how facility management activities are performed.

Why facility management terminology matters

Facility management brings together the planning, operation, and improvement of the built environment and the services that support it. The subject spans technical operation, user services, maintenance, space use, and organisational coordination, so clear definitions are important when different stakeholders work from the same document set. A common vocabulary helps reduce ambiguity between owners, operators, service providers, and technical teams.

As a terminology document, this standard is about conceptual consistency: it defines the language used to describe facility management, not the operational performance of a facility. In practice, such terminology standards help structure communication, documentation, contracts, and related technical standards by giving the field a stable reference language.

• Harmonised naming for common facility management concepts
• Clear separation of building, service, and organisational ideas
• More consistent communication between technical and administrative stakeholders
• A terminology basis for related facility management documents
