Blinds and shutters - Thermal and visual comfort - Performance characteristics and classification
This document applies to the whole range of shutters, awnings and blinds defined in EN 12216, described as solar protection devices in this document.
It specifies the corresponding properties and classifications:
- relating to thermal comfort:
- the solar factor (total solar energy transmittance);
- the secondary heat transfer factor;
- the direct solar transmittance;
- relating to visual comfort:
- the darkening performance;
- the night privacy;
- the visual contact with the outside;
- the glare control;
- the daylight utilization;
- the rendering of colours.
NOTE For other purposes, more detailed methods using different parameters can be used.
Some of the characteristics (e.g. gtot) are not applicable when solar protection devices are not parallel to the glazing (e.g. folding-arm awnings).
This document is not applicable to the solar protection devices using fluorescent materials.
Abschlüsse - Thermischer und visueller Komfort - Leistungsanforderungen und Klassifizierung
Dieses Dokument gilt für sämtliche Arten von Abschlüssen, Markisen und Jalousien, die in EN 12216 definiert sind und in diesem Dokument als Sonnenschutzeinrichtungen bezeichnet werden.
Es legt die entsprechenden Eigenschaften und Klassifizierungen fest:
- in Bezug auf thermischen Komfort:
- den Sonnenfaktor (Gesamtenergiedurchlassgrad);
- den sekundären Wärmeabgabegrad nach innen;
- den direkten Strahlungstransmissionsgrad;
- in Bezug auf visuellen Komfort:
- die Verdunkelungsleistung;
- den Sichtschutz bei Nacht;
- den Sichtkontakt nach außen;
- den Blendschutz;
- die Tageslichtnutzung;
- den Farbwiedergabeindex.
ANMERKUNG Für andere Verwendungszwecke können detailliertere Verfahren mit anderen Parametern angewendet werden.
Einige Merkmale (z. B. gtot) sind nicht anwendbar, wenn Sonnenschutzeinrichtungen nicht parallel zur Verglasung angebracht sind (z. B. Gelenkarm-Markisen).
Dieses Dokument ist nicht auf Sonnenschutzeinrichtungen anwendbar, bei denen fluoreszierende Materialien verwendet werden.
Fermetures et stores - Confort thermique et lumineux - Caractérisation des performances et classification
Ce document s'applique à l'ensemble des fermetures, stores extérieurs et stores intérieurs définis dans la norme EN 12216, décrits comme des dispositifs de protection solaire dans la présente Norme européenne.
Il spécifie les propriétés et les classifications correspondantes :
- liées au confort thermique :
- le facteur solaire (facteur de transmission de l'énergie solaire totale) ;
- le facteur de transfert de chaleur secondaire ;
- le facteur de transmission solaire directe ;
- liées au confort lumineux :
- la performance d'assombrissement ;
- l'intimité de nuit ;
- le contact visuel avec l'extérieur ;
- le contrôle de l'éblouissement ;
- l'utilisation de la lumière naturelle ;
- le rendu des couleurs.
NOTE Pour d'autres objets, des méthodes plus détaillées utilisant des paramètres différents peuvent être utilisées.
Certaines caractéristiques (par exemple gtot) ne sont pas applicables lorsque les dispositifs de protection solaire ne sont pas parallèles au vitrage (par exemple, les stores bannes).
Ce document n'est pas applicable aux dispositifs de protection solaire qui utilisent des matériaux fluorescents.

European foreword
This document (EN 14501:2021) has been prepared by Technical Committee CEN/TC 33 “Doors, windows,
shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR.
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 September 2021, and conflicting national standards shall be
withdrawn at the latest by September 2021.
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 supersedes EN 14501:2005.
The main modifications of this project of revision are relating to:
— the revision of the performance classification for the darkening performance;
— the revision of the performance classification for the glare control. The new classification is based on DGP
(Daylight Glare Probability) calculations and considers the cut-off angle of the curtain material;
— the addition of a fifth reference glazing (triple glazing);
— the addition of an informative annex giving recommendations on the class for glare control to be used
depending on the location and orientation of the building, as well as on the size of the glazed area, the
distance from the façade and the light transmittance of the glazing.
According to the CEN-CENELEC Internal Regulations, the national standards organisations 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.
