(Main)Daylight in buildings
Daylight in buildings
This document specifies elements for achieving, by means of natural light, an adequate subjective impression of lightness indoors, and for providing an adequate view out. In addition, recommendations for the duration of sunshine exposure within occupied rooms are given.
This document gives information on how to use daylighting to provide lighting within interiors, and how to limit glare. This document defines metrics used for the evaluation of daylighting conditions and gives principles of calculation and verification. These principles allow to address the issue of variability of daylight over the days and the year.
This document applies to all spaces that may be regularly occupied by people for extended periods except where daylighting is contrary to the nature and role of the actual work done.
The specification of lighting requirements for humans in indoor work places including visual tasks are given in EN 12464-1 and are not part of this document.
Tageslicht in Gebäuden
Dieses Dokument legt Empfehlungen zur Erreichung eines hinreichenden subjektiven Helligkeitseindrucks in Innenräumen durch Tageslicht und einer ausreichenden Aussicht fest. Darüber hinaus enthält das Dokument Empfehlungen für die Dauer der Besonnung in Aufenthaltsräumen.
Dieses Dokument bietet Informationen zur Nutzung des Tageslichts für die Beleuchtung von Innenräumen und die Beschränkung von Blendung. Darüber hinaus legt dieses Dokument Messgrößen für die Bewertung der Tageslichtbeleuchtungsbedingungen fest und enthält Grundsätze für die Berechnung und Verifizierung. Diese Grundsätze ermöglichen es, die Variabilität des Tageslichts zu verschiedenen Tages- und Jahreszeiten zu berücksichtigen.
Dieses Dokument gilt für alle regelmäßig und über längere Zeit von Menschen genutzten Räume, mit Ausnahme von Räumen, in denen eine Tageslichtbeleuchtung der Nutzung des Raumes entgegensteht.
Die Festlegungen der Beleuchtungsanforderungen für Personen an Arbeitsplätzen in Innenräumen einschließlich visueller Aufgaben sind in EN 12464-1 enthalten und nicht Teil dieses Dokuments.
Lumière naturelle dans les bâtiments
Le présent document spécifie les critères permettant d’obtenir, par le biais de la lumière naturelle, une impression subjective adéquate de clarté à l’intérieur et d’assurer une vue adéquate sur l’extérieur. En outre, des recommandations sont données concernant la durée d’exposition à l’ensoleillement direct à l’intérieur des locaux (ou pièces) occupés.
Le présent document fournit des informations sur la façon d’exploiter l’éclairage naturel pour assurer l’éclairage en intérieur, ainsi que les moyens de réduire l’éblouissement. Le présent document définit les systèmes de mesure utilisés pour évaluer les conditions d’éclairage naturel et fournit les principes de calcul et de vérification. Ces principes permettent de traiter de l’aspect de variabilité de la lumière naturelle au fil des jours et de l’année.
Le présent document s’applique à tous les espaces pouvant être occupés par des personnes de façon régulière et sur de longues périodes, à l’exception des espaces dans lesquels l’éclairage naturel est en inadéquation avec la nature et la fonction des travaux réalisés.
Les exigences en matière d’éclairage vis-à-vis des personnes occupant des lieux de travail intérieurs, y compris les tâches visuelles, sont spécifiées dans l’EN 12464 1 et ne font pas partie du présent document.
