Glass in building - Determination of luminous and solar characteristics of glazing
This European Standard specifies methods of determining the luminous and solar characteristics of glazing in buildings. These characteristic can serve as a basis for lighting, heating and cooling calculations of rooms and permit comparison between different types of glazing.
This European Standard applies both to conventional glazing and to absorbing or reflecting solar-control glazing, used as vertical or horizontal glazed apertures. The appropriate formulae for single, double and triple glazing are given.
This European Standard is accordingly applicable to all transparent materials except those which show significant transmission in the wavelength region 5 µm to 50 µm of ambient temperature radiation, such as certain plastic materials.
Materials with light-scattering properties for incident radiation are dealt with as conventional transparent materials subject to certain conditions (see 5.2).
Angular light and solar properties of glass in building are excluded from this Standard. However, research work in this area is summarised in E.1, E.2 and E.3.
While this European Standard presents the formulae for the exact calculations of the spectral characteristics of glazing, it does not consider the uncertainty of the measurements necessary to determine the spectral parameters that are used in the calculations. It should be noted that, for simple glazing systems where few measurements are required, the uncertainty of the results will be satisfactory if correct measurements procedures have been followed. When the glazing systems become complex and a large number of measurements are required to determine the spectral parameters, the uncertainty is cumulative with the number of measurements and should be considered in the final results.
The term interface used in this European Standard, is considered to be a surface characterized by its transmission and reflections of light intensities.
Glas im Bauwesen - Bestimmung der lichttechnischen und strahlungsphysikalischen Kenngrößen von Verglasungen
Diese Europäische Norm legt Verfahren zur Bestimmung der lichttechnischen und strahlungsphysikalischen Kenngrößen von Verglasungen von Gebäuden fest. Diese Kenngrößen können als Grundlage für licht-, heizungs- und klimatechnische Berechnungen dienen. Sie ermöglichen den Vergleich zwischen unter-schiedlichen Verglasungen. Diese Europäische Norm ist sowohl anwendbar auf übliche Verglasungen als auch auf absorbierende oder reflektierende Sonnenschutzgläser, eingesetzt in senkrechten oder waagerechten Lichtöffnungen. Die geeigneten Gleichungen für Einfach-, Doppel- und Dreifachverglasungen sind angegeben. Diese Europäische Norm ist für sämtliche lichtdurchlässige Materialien entsprechend anwendbar, ausge-nommen solche, die eine nennenswerte Transmission im Wellenlängenbereich von 5 µm bis 50 µm von Strahlung bei Raumtemperatur aufweisen, wie z. B. gewisse Kunststoffe. Materialien mit lichtstreuenden Eigenschaften für die auftreffende Strahlung werden grundsätzlich wie normale lichtdurchlässige Stoffe unter Beachtung bestimmter Bedingungen (siehe 5.2) behandelt. Die Eigenschaften von schrägem Licht und die Strahlungseigenschaften von Glas in Gebäuden werden in dieser Norm nicht erfasst. Forschungsarbeiten, die in diese Richtung gehen, werden jedoch zusammen-fassend in [1], [2] und [3] dargestellt.
Verre dans la construction - Détermination des caractéristiques lumineuses et solaires des vitrages
La présente Norme européenne spécifie les méthodes de détermination des caractéristiques lumineuses et solaires des vitrages de bâtiment. Ces caractéristiques peuvent servir de base aux calculs relatifs à l'éclairement et au conditionnement thermique des locaux et permettre d'établir des comparaisons entre différents types de vitrage. La présente Norme européenne s'applique aussi bien aux vitrages conventionnels qu'à ceux présentant des propriétés d'absorption et de réflexion de l'énergie solaire, et utilisés comme vitrages verticaux ou horizontaux. Des formules appropriées sont établies pour des vitrages simples, doubles ou triples. La présente Norme européenne s'applique à tous les matériaux transparents, à l'exception de ceux qui présentent une transmission non négligeable dans le domaine spectral de 5 µm à 50 µm du rayonnement émis par les corps à température ambiante, telles certaines feuilles de matériaux plastiques. Les matériaux caractérisés par des propriétés de diffusion du rayonnement incident sont traités comme des matériaux transparents conventionnels sous certaines réserves (voir 5.2). Les propriétés angulaires solaires et lumineuses du verre utilisé dans la construction sont exclues de la présente norme. Toutefois, les travaux de recherche dans ce domaine sont résumés en Bibliographie [1], [2] et [3].
Steklo v gradbeništvu - Določevanje svetlobnih in sončnih karakteristik stekla
Ta evropski standard določa metode za določevanje svetlobnih in sončnih karakteristik stekla v zgradbah. Te karakteristike se lahko uporabljajo kot osnova za izračune osvetljave, gretja in hlajenja prostorov in omogočajo primerjavo med različnimi vrstami stekla.
Ta evropski standard velja za konvencionalno steklo in za absorpcijsko ali odsevno steklo za nadzor sonca, ki se uporablja kot navpična ali vodoravna steklena odprtina. Podane so ustrezne formule za enojno, dvojno in trojno steklo.
Ta evropski standard ustrezno velja za vse prosojne materiale, razen za tiste, ki kažejo bistveno prepustnost v območju valovnih dolžin med 5 µm in 50 µm sevanja okoljske temperature, kot so nekateri plastični materiali.
Materiali z lastnostmi sipanja svetlobe za naključno sevanje se obravnavajo kot konvencionalni prosojni materiali ob upoštevanju nekaterih zahtev (glej 5.2).
Kotna svetloba in sončne lastnosti stekla v gradbeništvu so izvzete iz tega standarda. Raziskovalno delo s tega področja pa je povzeto v E.1, E.2 in E.3.
Medtem ko ta evropski standard predstavlja formule za natančne izračune spektralnih lastnosti stekla, ne obravnava negotovosti potrebnih meritev za določanje spektralnih parametrov, ki se uporabljajo pri izračunih. Treba je upoštevati, da je pri preprostih steklenih sistemih, pri katerih je potrebnih le malo meritev, negotovost rezultatov zadovoljiva, če se upoštevajo pravilni postopki merjenja. Če pa so stekleni sistemi kompleksni in je za določanje spektralnih parametrov potrebno več meritev, je negotovost kumulativna glede na število meritev in se mora upoštevati pri končnih rezultatih.
Izraz vmesnik, ki se uporablja v tem evropskem standardu, je površina, ki jo označujeta prosojnost in odsevi svetlobnih intenzitet.

SIST EN 410:2011
The term interface used in this European Standard, is considered to be a surface characterized by its transmission and reflections of light intensities. That is, the interaction with light is incoherent, all phase information being lost. In the case of thin films (not described in this European Standard), interfaces are characterized by transmission and reflections of light amplitudes, i.e. the interaction with light is coherent and phase information is available. Finally, for clarity, a coated interface can be described as having one or more thin films, but the entire stack of thin films is characterized by its resulting transmission and reflection of light intensities. In Annex B, the procedure for the calculation of spectral characteristics of laminated glass makes specific reference to coated glass. The same procedure can be adopted for filmed glass (e.g. adhesive backed polymeric film applied to glass). SIST EN 410:2011
