TS EN 15221-1

TS EN 15221-1 is the standard that organises the core terms and definitions used in facility management. It provides a common vocabulary for a field where buildings, support services and organisational needs must be described consistently, helping different teams and stakeholders use the same concepts with the same meaning.

How the facility management vocabulary works

Facility management brings together the coordination of physical spaces, building operation, support services and related processes that help an organisation achieve its main business aims. In general technical terms, this includes the relationship between the built environment, service delivery, users and management structures. A terms-and-definitions standard does not prescribe operating methods; instead, it fixes the meaning of key expressions so that contracts, reports and internal documentation can be written without ambiguity.

Why definitions matter in practice

In a multi-disciplinary environment, the same word may be used differently by property, maintenance, procurement or management teams. A terminology standard reduces that risk by giving agreed meanings to the concepts most often used in the discipline. That makes it easier to compare information, align responsibilities and communicate clearly across organisations and projects.

This listing represents the English-language European standard equivalent for facility management terminology. Its value lies in conceptual clarity rather than performance requirements: it supports a shared technical language for anyone working with facility management documents, service structures or organisational planning.
