Solar protection devices combined with glazing - Calculation of solar and light transmittance - Part 1: Simplified method
This European Standard specifies a simplified method based on the thermal transmittance and total solar energy transmittance of the glazing and on the light transmittance and reflectance of the solar protection device to estimate the total solar energy transmittance of a solar protection device combined with glazing. The method applies to all types of solar protection devices parallel to the glazing such as louvre, venetian or roller blinds. The position of the solar protection device can be interior, exterior or between single panes in a dual glazing system. It is applicable when the total solar energy transmittance of the glazing is between 0,15 and 0,85. Venetian or louvre blinds are assumed to be adjusted so that there is no direct solar penetration. It is assumed that for external solar protection devices and for integrated solar protection devices, the space between the solar protection devices and the glazing is unventilated and for internal solar protection devices this space is ventilated. !The resulting g-values of the simplified method given here are approximate and their deviation from the exact values lie within the range between +0,10 and -0,02. The results generally tend to lie on the safe side for cooling load estimations. The results are not intended to be used for calculating beneficial solar gains or thermal comfort criteria. The simplified method is based on the normal incidence of radiation and does not take into account either the angular dependence of transmittance and the reflectance or the differences of spectral distribution.
Sonnenschutzeinrichtungen in Kombination mit Verglasungen - Berechnung der Solarstrahlung und des Lichttransmissionsgrades - Teil 1: Vereinfachtes Verfahren
Diese Norm legt ein vereinfachtes Verfahren zur Bewertung des Gesamtenergiedurchlassgrades einer Sonnenschutzvorrichtung in Kombination mit einer Verglasung fest, das auf dem Wärmedurchgangs-koeffizienten und dem Gesamtenergiedurchlassgrad der Verglasung sowie dem Lichttransmissions und Lichtreflexions-grad der Sonnenschutzvorrichtung beruht.
Das Verfahren gilt für alle Arten von Sonnenschutzvorrichtungen in Kombination mit der Verglasung, wie Lamellensysteme, Jalousien und Rollladen. Die Einbaulage der Sonnenschutzvorrichtung kann sich innen, außen oder bei einer Doppelverglasung zwischen den Einzelscheiben befinden. Der Gesamtenergie-durchlassgrad (g-Wert) der Verglasung muss zwischen 0,15 und 0,85 sein. Jalousien und Lamellensysteme müssen so eingestellt sein, dass kein direkter Durchtritt von Solarstrahlung möglich ist. Bei außen liegenden Sonnenschutzvorrichtungen und eingebauten Sonnenschutzvorrichtungen wird vorausgesetzt, dass der Zwischenraum zwischen den Sonnenschutzvorrichtungen und der Verglasung unbelüftet ist, während der Zwischenraum bei innen liegenden Sonnenschutzvorrichtungen belüftet ist.
!Die Ergebnisse, die g-Werte, des hier angegebenen vereinfachten Verfahrens sind Näherungswerte und liegen im Vergleich zu genaueren Verfahren im Bereich zwischen + 0,10 und 0,02. Bei Bewertungen der Kühlbelastung tendieren die Ergebnisse im Allgemeinen in Richtung der sicheren Seite. Die Ergebnisse sind nicht zur Berechnung solarer Energiegewinne oder zur Bewertung der wärmetechnischen Behaglichkeit vorgesehen. Das vereinfachte Verfahren beruht auf normal einfallender Strahlung und berücksichtigt weder die Winkel¬abhängigkeit von Transmissions und Reflexionsgrad noch die Unterschiede der Spektralverteilung.
Für die Anwendung dieser Norm müssen die Transmission und die Reflexion von Sonnenschutzvorrichtungen im folgenden Bereich liegen:
0 ≤ e,B ≤ 0,5 und 0,1 ≤ e,B ≤ 0,8
Für andere Daten ist die Berechnung nach EN 13363-2 [1] durchzuführen. "
Dispositifs de protection solaire combinés a des vitrages - Calcul du facteur de transmission solaire et lumineuse - Partie 1: Méthode simplifiée
La présente Norme européenne donne une méthode simplifiée fondée sur le coefficient transmission thermique et celui de transmission de l’énergie solaire totale du vitrage ainsi que sur le facteur de transmission lumineuse et le facteur de réflexion du dispositif de protection solaire pour estimer la transmission totale d’énergie solaire d'un dispositif de protection contre le soleil combiné à un vitrage.
La méthode s’applique à tous les types de dispositifs de protection solaire montés en parallèle au vitrage, tels que les stores à claire-voie, les jalousies ou les volets roulants. La position du dispositif de protection solaire peut être à l'intérieur, à l'extérieur ou entre les panneaux dans un système de double vitrage. Elle est applicable lorsque le facteur total de transmission d'énergie solaire du vitrage est compris entre 0,15 et 0,85. Les jalousies ou dispositif de protection solaires à claire-voie doivent pouvoir être réglés afin qu'il n'y ait aucune transmission solaire directe. Il est supposé que pour les dispositifs de protection solaires extérieurs et les dispositifs de protection solaire intégrés, l'espace entre les dispositifs de protection solaires et le vitrage n'est pas ventilé, et que pour les dispositifs de protection solaire intérieurs, cet espace est ventilé.
!Les valeurs de g résultant de la méthode simplifiée donnée dans la présente Norme sont approximatives et leurs écarts par rapport aux valeurs exactes se situent dans la plage 0,10 à – 0,02. Les estimations de la charge de refroidissement ont généralement tendance à privilégier la sécurité. Leurs résultats ne sont pas destinés à être utilisés pour calculer les gains solaires ou les critères de confort thermique. La méthode simplifiée se fonde sur une incidence normale des rayonnements et ne tient pas compte de l’effet d’une inclinaison quelconque sur les facteurs de transmission et de réflexion, ou des différences de répartition spectrale.
La présente Norme peut s’appliquer lorsque le

EN 13363-1:2003+A1:2007 (E) 4 This standard can be applied when the solar transmittance and solar reflectance of the solar protection devices are within the following ranges:
0 ≤ τe,B ≤ 0,5 and 0,1 ≤ ρe,B ≤ 0,8
For reflectance and transmittance values outside these ranges EN 13363-2 [1] applies. An allowance can be made for this fact when applying the method. For cases not covered by the method given in this standard more exact calculations based on the optical properties (in general the spectral data) of glass and solar protection device can be carried out in accordance with EN 13363-2 [1]." 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
