Energy performance of buildings - Thermal, solar and daylight properties of building components and elements - Part 3: Detailed calculation method of the solar and daylight characteristics for solar protection devices combined with glazing (ISO 52022-3:2017)

This document specifies a detailed method, based on the spectral transmission data of the materials, comprising the solar protection devices and the glazing, to determine the total solar energy transmittance and other relevant solar-optical data of the combination. If spectral data are not available the methodology can be adapted to use in-tegrated data.
The method is valid for all types of solar protection devices parallel to the glazing such as louvres, or venetian, or roller blinds. The blind may be located internally, externally, or enclosed between the panes of the glazing. Ventilation of the blind is allowed for in each of these positions in determining the solar energy absorbed by the glazing or blind components, for vertical orientation of the glazing.
The blind component materials may be transparent, translucent or opaque, combined with glazing components with known solar transmittance and reflectance and with known emissivity for thermal radiation.
The method is based on a normal incidence of radiation and does not take into account an angular dependence of transmittance or reflectance of the materials. Diffuse irradiation or radiation diffused by solar protection devices is treated as if it were direct. Louvres or venetian blinds are treated as homogenous materials by equivalent solar optical characteristics, which may depend on the angle of the incidence radiation. For situations outside the scope of this document; ISO 15099 covers a wider range of situations.
The document also gives certain normalised situations, additional assumptions and necessary boundary conditions.
No change to the scope is expected. There will be editorial revision (new structure) in the context of Mandate M/480 and maybe minor technical changes due to inconsistency to other standards under Mandate M/480

Energieeffizienz von Gebäuden - Wärmetechnische, solare und tageslichttechnische Eigenschaften von Bauteilen und Bauelementen - Teil 3: Detailliertes Berechnungsverfahren zur Ermittlung der solaren und lichttechnischen Eigenschaften von Sonnenschutz in Kombination mit Verglasungen (ISO 52022-3:2017)

Dieses Dokument legt ein detailliertes Berechnungsverfahren auf der Grundlage von spektralen Transmissions- und Reflexionsgraddaten der Materialien der Komponenten (Sonnenschutzvorrichtungen und Verglasung) fest, mit dessen Hilfe der Gesamtenergiedurchlassgrad, der Gesamtlichttransmissionsgrad und andere relevante solar-optische Kenngrößen der Kombination ermittelt werden können. Falls keine spektralen Kenngrößen zur Verfügung stehen, kann das Verfahren zur Verwendung von integrierten Kenngrößen angepasst werden.
Das Verfahren gilt für alle Arten von parallel zur Verglasung angeordneten Sonnenschutzvorrichtungen, wie Lamellensysteme, Jalousien und Rollläden. Die Sonnenschutzvorrichtung kann sich innen, außen oder bei einer Doppelverglasung zwischen den Einzelscheiben befinden. Bei der Bestimmung der von der Verglasung oder von den Komponenten der Sonnenschutzvorrichtung absorbierten Solarenergie ist in jeder dieser Positionen eine Belüftung der Sonnenschutzvorrichtung bei vertikaler Ausrichtung der Verglasung zulässig.
Die Materialien der Sonnenschutzvorrichtung können durchsichtig, durchscheinend oder opak sein und mit Verglasungen kombiniert werden, deren Transmissions- und Reflexionsgrade für Solarstrahlung und Emissionsgrade für Wärmestrahlung bekannt sind.
Das Verfahren beruht auf normal einfallender Strahlung und berücksichtigt nicht die Abhängigkeit vom Transmissions- und Reflexionswinkel des Materials. Eine diffuse Einstrahlung oder eine Strahlung, die durch Sonnenschutzvorrichtungen zerstreut wird, wird als direkte Strahlung angesehen. Lamellensysteme und Jalousien werden als homogene Materialien mit äquivalenten solar-optischen Eigenschaften behandelt, die vom Einfallswinkel der Strahlung abhängig sein können. Das aktuelle Verfahren ist auf vertikale Installationen mit einer Neigung von ±15° beschränkt. Für Situationen außerhalb des Anwendungsbereichs dieses Dokuments berücksichtigt ISO 15099 einen breiteren Bereich von Situationen.
Dieses Dokument enthält außerdem Beschreibungen bestimmter Standardsituationen, zusätzliche Annahmen und notwendige Randbedingungen.
ANMERKUNG Tabelle 1 in der Einleitung zeigt die relative Position dieses Dokuments innerhalb des EPB-Normenpakets im Kontext der in ISO 520001-1 dargelegten modularen Struktur.

Energetska učinkovitost stavb - Lastnosti gradbenih komponent in elementov glede toplote, sončnega obsevanja in dnevne svetlobe - 3. del: Podrobna računska metoda za določitev značilnosti sončnega obsevanja in dnevne svetlobe za senčila v kombinaciji z zasteklitvijo (ISO 52022-3:2017)

Ta dokument določa podrobno metodo, ki temelji na spektralnih podatkih prehodnosti materialov, vključno s senčili in zasteklitvijo, za ugotavljanje skupne prehodnosti sončne energije in drugih pomembnih solarno-optičnih podatkov kombinacije. Če spektralni podatki niso na voljo, je mogoče prilagoditi metodologijo tako, da se uporabijo integrirani podatki. Metoda se uporablja za vse vrste senčil, vzporednih z zasteklitvijo, kot so lamelne zavese, žaluzije ali rolete. Senčilo je lahko nameščeno znotraj, zunaj ali med enojnimi stekli v zasteklitvi. Prezračevanje senčila je omogočeno v vsakem od teh položajev pri določanju količine sončne energije, ki jo absorbirajo komponente zasteklitve ali senčila, za navpično usmerjeno zasteklitev. Materiali komponent senčila so lahko prozorni, prosojni ali neprosojni v kombinaciji s komponentami zasteklitve z znanimi vrednostmi solarne prehodnosti ali odsevnosti in emisivnosti za toplotno sevanje. Metoda temelji na nazivni pojavnosti sevanja in ne upošteva kotne odvisnosti prehodnosti ali odsevnosti materialov. Razpršeno obsevanje ali sevanje, razpršeno s senčili, se obravnava kot neposredno. Lamelne zavese ali žaluzije se obravnavajo kot homogeni materiali z enakovrednimi solarno-optičnimi lastnostmi, ki so lahko odvisne od kota pojavnega sevanja. Večji obseg primerov zunaj področja uporabe tega dokumenta zajema ISO 15099. Dokument podaja tudi nekatere normalizirane primere, dodatne predpostavke in potrebne mejne pogoje. Področje uporabe predvidoma ne bo spremenjeno. Opravljena bo uredniška revizija (nova struktura) v kontekstu mandata M/480 in morda manjše tehnične spremembe zaradi nedoslednosti z drugimi standardi v okviru mandata M/480.

Introduction
This document is part of a series aimed at the international harmonization of the methodology for
assessing the energy performance of buildings. Throughout, this series is referred to as a “set of EPB
standards”.
All EPB standards follow specific rules to ensure overall consistency, unambiguity and transparency.
All EPB standards provide a certain flexibility with regard to the methods, the required input data and
references to other EPB standards, by the introduction of a normative template in Annex A and Annex B
with informative default choices.
For the correct use of this document, a normative template is given in Annex A to specify these choices.
Informative default choices are provided in Annex B.
The main target groups for this document are architects, engineers and regulators.
Use by or for regulators: In case this document is used in the context of national or regional legal
requirements, mandatory choices may be given at national or regional level for such specific
applications. These choices (either the informative default choices from Annex B or choices adapted to
national/regional needs, but in any case following the template of this Annex A) can be made available
as national annex or as separate (e.g. legal) document (national data sheet).
NOTE 1 So in this case:
— the regulators will specify the choices;
— the individual user will apply the document to assess the energy performance of a building, and thereby use
the choices made by the regulators.
Topics addressed in this document can be subject to public regulation. Public regulation on the same
topics can override the default values in Annex B of this document. Public regulation on the same topics
can even, for certain applications, override the use of this document. Legal requirements and choices
are in general not published in standards but in legal documents. In order to avoid double publications
and difficult updating of double documents, a national annex may refer to the legal texts where national
choices have been made by public authorities. Different national annexes or national data sheets are
possible, for different applications.
It is expected, if the default values, choices and references to other EPB standards in Annex B are not
followed due to national regulations, policy or traditions, that:
— national or regional authorities prepare data sheets containing the choices and national or regional
values, according to the model in Annex A. In this case a national annex (e.g. NA) is recommended,
containing a reference to these data sheets;
— or, by default, the national standards body will consider the possibility to add or include a national
annex in agreement with the template of Annex A, in accordance to the legal documents that give
national or regional values and choices.
Further target groups are parties wanting to motivate their assumptions by classifying the building
energy performance for a dedicated building stock.
More information is provided in the Technical Report accompanying this document (ISO/TR 52022-2).
The framework for overall EPB includes:
a) common terms, definitions and symbols;
b) building and assessment boundaries;
c) building partitioning into space categories;

and one module could be covered by more than one EPB standard, for instance, a simplified and a detailed method
respectively. See also Tables A.1 and B.1.

Energy performance of buildings — Thermal, solar
and daylight properties of building components and
elements —
Part 3:
Detailed calculation method of the solar and daylight
characteristics for solar protection devices combined
with glazing
1 Scope
This document specifies a detailed method, based on spectral data of the transmittance and reflectance
of the constituent materials (solar protection devices and the glazing), to determine the total solar
energy transmittance, the total light transmittance and other relevant solar-optical data of the
combination. If spectral data are not available, the methodology can be adapted to use integrated data.
The method is valid for all types of solar protection devices parallel to the glazing such as louvres,
venetian blinds, or roller blinds. The blind may be located internally, externally, or enclosed between
the panes of the glazing. Ventilation of the blind is allowed for in each of these positions in determining
the solar energy absorbed by the glazing or blind components, for vertical orientation of the glazing.
The blind component materials may be transparent, translucent or opaque, combined with glazing
components with known solar transmittance and reflectance and with known emissivity for thermal
radiation.
The method is based on a normal incidence of radiation and does not take into account an angular
dependence of transmittance or reflectance of the materials. Diffuse irradiation or radiation diffused
by solar protection devices is treated as if it were direct. Louvres or venetian blinds are treated as
homogenous materials by equivalent solar optical characteristics, which may depend on the angle of the
incidence radiation. The current method is limited to vertical installation ±15°. For situations outside
the scope of this document; ISO 15099 covers a wider range of situations.
The document also gives certain normalized situations, additional assumptions and necessary
boundary conditions.
