Accessibility and usability of the built environment - Functional requirements
This document describes basic, minimum functional requirements and recommendations for an accessible and usable built environment, following "Design for All"/"Universal Design" principles which will facilitate equitable and safe use for a wide range of users, including persons with disabilities.
The requirements and recommendations given in this document are applicable across the full spectrum of the built environment.
These functional accessibility and usability requirements and recommendations are relevant to the design, construction, refurbishment or adaptation, and maintenance of built environments including outdoor pedestrian and urban areas.
NOTE 1 ‘Design for All’ and ‘Universal Design’ share a similar inclusive design philosophy. "Universal Design" means the design of products, environments, programmes and services to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. "Universal Design" does not exclude assistive devices for particular groups of persons with disabilities where this is needed.
NOTE 2 Terms such as "design for all", "universal design", "accessible design", "barrier-free design", "inclusive design" and "transgenerational design" are often used interchangeably with the same meaning.
NOTE 3 This document does not cover management and maintenance issues, but provides basic information in Annex B.
NOTE 4 All figures are provided as examples. They are described by their title and key and do not provide additional information. Some figures show negative examples to be avoided; these are identified by the insertion of a red cross on them. A list of all the figures included is this document is given in the informative Annex C.
NOTE 5 In the case of refurbishment or adaptations of existing buildings or infrastructures, a specific study including feasibility determines the extent to which the functional requirements and recommendations can be met.
Barrierefreiheit und Nutzbarkeit der gebauten Umgebung. Funktionale Anforderungen
Dieses Dokument beschreibt die grundlegenden funktionalen Mindestanforderungen und Empfehlungen für eine nach den Grundsätzen "Design für alle"/"universelles Design" (en: Design for All/ en: Universal Design) barrierefreie gebaute Umwelt, die eine gleichberechtigte und sichere Nutzung durch einen großen Nutzerkreis, auch durch Menschen mit Behinderungen, ermöglicht.
Die in diesem Dokument angegebenen Anforderungen und Empfehlungen gelten für das gesamte Spektrum der gebauten Umwelt.
Diese funktionalen Anforderungen und Empfehlungen für die Barrierefreiheit sind für die Planung, den Neubau, die Sanierung oder den Umbau sowie für die Wartung der gebauten Umwelt, einschließlich der Fußgängerbereiche in Außenanlagen und in Stadträumen, relevant.
ANMERKUNG 1 "Design for All" und "Universal Design" teilen eine ähnliche inklusive Design-Philosophie. "Universal Design" steht für die Gestaltung von Produkten, Umgebungen, Programmen und Dienstleistungen in der Weise, dass sie von allen Personen möglichst weitgehend ohne eine Anpassung oder eine spezielle Gestaltung genutzt werden können. "Universal Design" schließt Hilfsvorrichtungen, die von bestimmten Gruppen von Menschen mit Behinderungen benötigt werden, nicht aus.
ANMERKUNG 2 Begriffe wie "Design for All", "Universal Design", "zugängliche Gestaltung", "barrierefreie Gestaltung", "inklusive Gestaltung" und "generationenübergreifende Gestaltung" werden häufig synonym verwendet.
ANMERKUNG 3 Dieses Dokument behandelt keine Betriebs- und Wartungsaufgaben, liefert hierzu aber grundlegende Informationen in Anhang B.
ANMERKUNG 4 Alle dargestellten Bilder sind Beispielbilder. Sie werden durch ihre Bildunterschriften und Legenden beschrieben und liefern keine Zusatzinformationen. Einige Bilder zeigen Negativbeispiele, die es zu vermeiden gilt; um sie zu kennzeichnen, sind sie mit einem roten Kreuz durchgestrichen. Der informative Anhang C enthält eine Liste aller in diesem Dokument enthaltenen Bilder.
ANMERKUNG 5 Im Falle einer Modernisierung oder einer Anpassung von bestehenden Gebäuden oder Infrastrukturen wird mithilfe einer spezifischen Untersuchung, welche die Machbarkeit berücksichtigt, den Umfang ermittelt, in dem die funktionalen Anforderungen und Empfehlungen erfüllt werden können.
Accessibilité et utilisabilité de l’environnement bâti - Exigences fonctionnelles
Le présent document décrit les exigences et recommandations fonctionnelles minimales de base pour un environnement bâti accessible et utilisable, selon les principes de « conception pour tous »/« conception universelle » qui visent à faciliter une utilisation sûre et équitable pour un large éventail d’utilisateurs, y compris les personnes handicapées.
Les exigences et recommandations données dans le présent document sont applicables à l’ensemble du domaine de l’environnement bâti.
Ces exigences et recommandations en matière d’accessibilité fonctionnelle et d’utilisabilité s’appliquent à la conception, à la construction, à la réhabilitation ou l’adaptation et à la maintenance des environnements bâtis, incluant les zones piétonnes et urbaines extérieures.
NOTE 1 La « conception pour tous » et la « conception universelle » partagent une philosophie de conception inclusive similaire. La « conception universelle » désigne la conception de produits, d’environnements, de programmes et de services destinés à être utilisés par tous, dans la mesure du possible, sans nécessiter d’adaptations ni de conception spécifique. La « conception universelle » n’exclut pas les appareils d’assistance pour des groupes particuliers de personnes handicapées lorsque cela est nécessaire.
NOTE 2 Les termes tels que « conception pour tous », « conception universelle », « conception accessible », « aménagement à accès facile », « conception inclusive » et « conception transgénérationnelle » sont souvent utilisés indifféremment, mais dans le même sens.
NOTE 3 Le présent document ne couvre pas les questions relatives à la gestion et à la maintenance, mais fournit des informations de base dans l’Annexe B.
NOTE 4 Toutes les figures sont données à titre d’exemple. Elles sont décrites par leur titre et leur légende et ne fournissent pas d’informations supplémentaires. Certaines figures montrent des exemples négatifs à éviter ; ces derniers sont identifiés par une croix rouge qui les barre. Une liste de toutes les figures incluses dans le présent document est donnée à l’Annexe C, informative.
NOTE 5 En cas de réhabilitation ou d’adaptation d’infrastructures ou de bâtiments existants, une étude spécifique, incluant notamment la faisabilité, détermine la mesure dans laquelle les exigences et recommandations fonctionnelles peuvent être satisfaites.

European foreword
This document (EN 17210:2021) has been prepared by the Joint Technical Committee CEN-
CENELEC/JTC 11 “Accessibility in the built environment”, the secretariat of which is held by UNE.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by July 2021 and conflicting national standards shall be
withdrawn at the latest by January 2024.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under Mandate M/420 given to CEN-CENELEC and ETSI by the
European Commission and the European Free Trade Association in support of European accessibility
requirements for public procurement in the built environment.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
Introduction
This document has been developed in response to mandate M/420 of the European Commission,
providing a standard for procurement of an accessible and usable built environment. The main goal of
this document is to contribute to the implementation of the United Nations Convention on the Rights of
Persons with Disabilities (UNCRPD) in Europe.
The functional requirements and recommendations in this document are formulated with qualitative
terms and describe the objectives which have to be reached, based on the diversity that a wide range of
users presents (goals for protection) and can be used as criteria for awarding public contracts (in support
of the Public Procurement Directives) as well as for other purposes, i.e. for accessibility legislation. This
document does not prescribe or describe how these functional requirements should be met and thus it is
not intended that this document will conflict with national accessibility standards.
This document specifies a range of functional accessibility and usability requirements and
recommendations for many of the elements of construction, assembly, interior settings, components and
fittings, which comprise the built environment. These functional accessibility requirements relate to the
constructional aspects of outdoor pedestrian and urban areas, approaches and access to buildings, indoor
circulation and use of facilities within buildings, egress from buildings in the normal course of events, and
evacuation in the event of an emergency.
The functional accessibility and usability requirements in this document are based on the widest range
of user needs and target groups as identified in Phase I of Mandate M/420. These requirements support
the diversity of all persons and a life-course perspective, i.e. persons with physical impairments, persons
with sensory impairments, persons with allergies, persons with learning difficulties/cognitive
impairments and persons with mental-ill-health, persons with age-related conditions, but also persons
in different stages of life, as children, adults and older persons.
This document also specifies the functional accessibility and usability requirements and
recommendations to enable the use of wheeled mobility devices in the built environment. The type of
wheeled mobility devices to be facilitated, and consequently the amount of space to be allocated, may be
determined by national standards or regulations and/or a procuring body may specify the provision of
space for larger electric wheelchairs and mobility scooters in certain types of buildings.
For the purpose of this document, the term ’accessibility’ refers to both ‘accessibility and usability’.
For specific building uses (see Clauses 16 to 20), such as accommodation, cultural, leisure and sport use,
administrative, service and employment buildings, and outdoor and urban areas and transport facilities,
the basic functional accessibility requirements are supplemented by key requirements and
recommendations supported by other related standards or guidance documents.
This document is based to a great extent on ISO 21542:2011 Building construction – Accessibility and
usability of the built environment (under revision) and where not sufficient, supplemented with
references to alternative and/or complementary documents (identified in Phase I of Mandate M/420).
This document is intended to assist primarily public procurers and also architects, engineers, facility
managers, ergonomists and other stakeholders in their respective areas of work, enabling them to
require, specify, design and assess conformity related to the accessibility of the built environment, using
a common framework and a common language, thus ensuring accessibility for all.
As a general structure, explanations on the motives for the requirements and recommendations given in
this document are given in previous short informative ‘Rationale’, understood as a background.
The technical performance criteria to fulfil the functional requirements given in this document, based on
classes, detailed dimensions, etc. will be exemplified by a CEN-CENELEC Technical Report “Accessibility
and usability of the built environment - Technical performance criteria and specifications” (TR 1), currently
under development, and may also be determined by national building regulations, national standards, or
any other national guidance.
Another CEN-CENELEC Technical Report (TR 2) on the assessment of conformity to the functional
requirements given in this document and the technical specifications given in NWI JT011002 is currently
also under development.
1 Scope
This document describes basic, minimum functional requirements and recommendations for an
accessible and usable built environment, following "Design for All"/"Universal Design" principles which
will facilitate equitable and safe use for a wide range of users, including persons with disabilities.
The requirements and recommendations given in this document are applicable across the full spectrum
of the built environment.
These functional accessibility and usability requirements and recommendations are relevant to the
design, construction, refurbishment or adaptation, and maintenance of built environments including
outdoor pedestrian and urban areas.
NOTE 1 ‘Design for All’ and ‘Universal Design’ share a similar inclusive design philosophy. “Universal Design”
means the design of products, environments, programmes and services to be usable by all people, to the greatest
extent possible, without the need for adaptation or specialized design. “Universal Design” does not exclude assistive
devices for particular groups of persons with disabilities where this is needed.
NOTE 2 Terms such as "design for all", "universal design", "accessible design", "barrier-free design", "inclusive
design" and "transgenerational design" are often used interchangeably with the same meaning.
NOTE 3 This document does not cover management and maintenance issues, but provides basic information in
Annex B.
NOTE 4 All figures are provided as examples. They are described by their title and key and do not provide
additional information. Some figures show negative examples to be avoided; these are identified by the insertion of
a red cross on them. A list of all the figures included is this document is given in the informative Annex C.
NOTE 5 In the case of refurbishment or adaptations of existing buildings or infrastructures, a specific study
including feasibility determines the extent to which the functional requirements and recommendations can be met.
