Building acoustics - Estimation of acoustic performance of buildings from the performance of elements - Part 5: Sounds levels due to the service equipment

This document describes calculation models to estimate the sound pressure level in buildings due to service equipment. As for the field measurement documents (EN ISO 16032 for the engineering method and EN ISO 10052 for the survey method), it covers sanitary installations, mechanical ventilation, heating and cooling, service equipment, lifts, rubbish chutes, boilers, blowers, pumps and other auxiliary service equipment, and motor driven car park doors, but can also be applied to others equipment attached to or installed in buildings. The estimation is generally based on measured data that characterizes both the equipment (source) and the sound transmission through the building. The same equipment can be composed of different airborne and/or structure borne sources at different locations in the building; the standard gives some information on these sources and how they can be characterized; however, models of the equipment itself are out of the scope of this standard.
This document describes the principles of the calculation models, lists the relevant input and output quantities and defines its applications and restrictions. The models given are applicable to calculations in frequency bands. It is intended for acoustical experts and provides the framework for the development of application documents and tools for other users in the field of building construction, considering local circumstances.
The calculation models described use the most general approach for engineering purposes, with a link to measurable input quantities that specify the performance of building elements and equipment. However, it is important for users to be aware that other calculation models also exist, each with their own applicability and restrictions.
The models are based on experience with predictions for dwellings and offices; they could also be used for other types of buildings provided the dimensions of constructions are not too different from those in dwellings.

Bauakustik - Berechnung der akustischen Eigenschaften von Gebäuden aus den Bauteileigenschaften - Teil 5: Installationsgeräusche

Dieses Dokument beschreibt Berechnungsmodelle für die durch gebäudetechnische Anlagen in Gebäuden erzeugten Schalldruckpegel. Wie in den Dokumenten zur Messung der Schallpegel in Gebäuden (EN ISO 16032 für das Standardverfahren und EN ISO 10052 für das Kurzverfahren) werden Sanitärinstallationen, maschinelle Lüftungssysteme, Heizung und Kühlung, gebäudetechnische Anlagen, Aufzüge, Müllrutschen, Heizkessel, Ventilatoren, Pumpen und anderes Zubehör zu gebäudetechnischen Anlagen sowie Garagentüren mit Motorantrieb erfasst, das Dokument kann aber auch auf andere Geräte, Anlagen oder Installationen (technische Gebäudeausrüstung) angewendet werden, die in Gebäuden angebracht oder installiert sind. Die Berechnung basiert grundsätzlich auf Messdaten, die sowohl die gebäudetechnische Anlage (Schallquelle) als auch die Schallübertragung durch das Gebäude charakterisieren. Dieselbe Ausrüstung kann aus verschiedenen Luft- und/oder Körperschallquellen an unterschiedlichen Stellen im Gebäude bestehen; die Norm stellt einige Informationen über diese Quellen bereit und wie sie charakterisiert werden können; Prognosemodelle für gebäudetechnischen Anlagen selbst fallen nicht in den Anwendungsbereich dieser Norm.
Das vorliegende Dokument beschreibt die Grundlagen der Berechnungsmodelle, führt die entsprechenden Eingabe- und Ausgabegrößen auf und legt ihre Anwendung sowie geltende Einschränkungen fest. Die angegebenen Modelle sind für Berechnungen in Frequenzbändern anwendbar. Das Dokument bietet Akustik-Fachleuten einen Rahmen zur Erstellung von Anwendungsdokumenten und Hilfsmitteln, die von anderen Anwendern im Bereich Bauausführung unter Berücksichtigung der örtlichen Gegebenheiten genutzt werden können.
Die Berechnungsmodelle beschreiben die Anwendung der für gebäudetechnische Anlagen gebräuchlichsten Methode unter Verweis auf messbare Eingabegrößen, die der Festlegung der Eigenschaften von Bauteilen und technischer Gebäudeausrüstung dienen. Die Anwender sollten jedoch bedenken, dass es auch andere Berechnungsmodelle gibt, von denen jedes für bestimmte Bereiche gut und für andere Bereiche nur eingeschränkt anwendbar ist.
Die Berechnungsmodelle berücksichtigen die Erfahrungen, die bei Prognosen für Wohnungen und Büroräume gewonnen wurden; sie könnten auf andere Gebäudearten unter der Voraussetzung übertragen werden, dass die Baumaße sich von denen von Wohnungen nicht zu stark unterscheiden.

Acoustique du bâtiment - Calcul de la performance acoustique des bâtiments à partir de la performance des éléments - Partie 5 : Niveaux de bruits dus aux équipements techniques

Le présent document décrit des modèles de calcul pour estimer le niveau de pression acoustique dans les bâtiments dû aux équipements techniques. Tout comme les documents de mesurage sur site (EN ISO 16032 pour la méthode d’expertise et EN ISO 10052 pour la méthode de contrôle), il couvre les installations sanitaires, la ventilation mécanique, le chauffage et le refroidissement, les équipements techniques, les ascenseurs, les vide-ordures, les chaudières, les appareils aérauliques, les pompes et autres équipements techniques auxiliaires et les portes de garage motorisées. Il peut également s’appliquer à d’autres équipements fixés ou installés dans les bâtiments. L’estimation repose généralement sur des données mesurées qui caractérisent à la fois l’équipement (source) et la transmission acoustique à travers le bâtiment. Un même équipement peut être composé de différentes sources de bruit aérien et/ou structural à différents endroits du bâtiment ; la présente norme fournit des informations sur ces sources ainsi que sur la façon dont elles peuvent être caractérisées. En revanche, les modèles de l’équipement lui-même n’entrent pas dans le domaine d’application de la présente norme.
Le présent document décrit les principes des modèles de calcul, énumère les grandeurs d’entrée et de sortie pertinentes et définit les applications et limites de ces modèles. Les modèles présentés sont applicables à un calcul par bandes de fréquences. Le présent document est destiné aux experts en acoustique et fournit un cadre pour le développement de documents applicatifs et d’outils destinés à d’autres utilisateurs dans le domaine de la construction des bâtiments, en tenant compte des conditions locales.
Les modèles de calcul décrits utilisent l’approche la plus générale pour les besoins de l’ingénierie, en lien avec des grandeurs d’entrée mesurables spécifiant les performances des éléments et équipements du bâtiment. Il convient toutefois que les utilisateurs sachent qu’il existe également d’autres modèles de calcul, chacun ayant sa propre applicabilité et ses propres restrictions.
Ces modèles s’appuient sur l’expérience en matière de prévision pour les bâtiments à usage d’habitation et de bureau. Ils peuvent également être utilisés pour d’autres types de bâtiments, dans la mesure où les dimensions des constructions ne sont pas trop différentes de celles des habitations.

1 Scope
This document describes calculation models to estimate the sound pressure level in buildings due to
service equipment. As for the field measurement documents (EN ISO 16032 for the engineering method
and EN ISO 10052 for the survey method), it covers sanitary installations, mechanical ventilation, heating
and cooling, service equipment, lifts, rubbish chutes, boilers, blowers, pumps and other auxiliary service
equipment, and motor driven car park doors, but can also be applied to others equipment attached to or
installed in buildings. The estimation is generally based on measured data that characterizes both the
equipment (source) and the sound transmission through the building. The same equipment can be
composed of different airborne and/or structure borne sources at different locations in the building; the
standard gives some information on these sources and how they can be characterized; however, models
of the equipment itself are out of the scope of this standard.
This document describes the principles of the calculation models, lists the relevant input and output
quantities and defines its applications and restrictions. The models given are applicable to calculations
in frequency bands. It is intended for acoustical experts and provides the framework for the development
of application documents and tools for other users in the field of building construction, considering local
circumstances.
The calculation models described use the most general approach for engineering purposes, with a link to
measurable input quantities that specify the performance of building elements and equipment. However,
it is important for users to be aware that other calculation models also exist, each with their own
applicability and restrictions.
The models are based on experience with predictions for dwellings and offices; they could also be used
for other types of buildings provided the dimensions of constructions are not too different from those in
dwellings.

4 Relevant quantities
4.1 General
This document describes calculation models to estimate the sound pressure level in buildings due to
service equipment. The output data of the models correspond to quantities expressing the building
performance (sound pressure levels in rooms generated by the equipment installed in the building), as
the input data correspond to quantities expressing the product performances for both the source(s) of
sound (the equipment itself) and the building elements involved in the transmission of sound.
In this standard, the output quantities are determined, like in EN ISO 12354-1 and EN ISO 12354-2, in
one-third octave bands at least in the frequency range 100 Hz to 3 150 Hz, possibly extended down to
one-third octave 50 Hz if building element data and junction data involved in the transmission of sound
are available, and up to 5 kHz, particularly for airborne sound quantities. Service equipment performance
data are based on measurements according to EN 15657 where measurements are performed in one-
third octave bands in the frequency range 50 Hz to 3 150 Hz. However, for some service equipment, the
frequency range of interest won’t cover this complete range.
NOTE For measuring airborne sound power of equipment in reverberant conditions, EN 15657:2017 refers
to EN ISO 3740 to EN ISO 3747, in which only limited information can be found for measurements performed in
small reverberant rooms, down to 50 Hz, in one-third octave band and applied to non-stationary sources, as well as
for their accuracy. Nevertheless, the measurement procedure is fully given in the standardized application
documents focused on laboratory measurements for each type of service equipment (for example, in EN 14366-1
for waste water pipes).
4.2 Quantities to express building performances (output quantities)
4.2.1 General
This standard aims at predicting sound pressure levels in buildings and comparing results to values
measured in situ. Field measurements of sound from equipment and machinery are performed according
to EN ISO 16032 (engineering method) or EN ISO 10052 (survey method) with results expressed in terms
of sound pressure level in various ways: maximum A-weighted and optionally C-weighted sound-
pressure levels using time weighting “S” or time weighting “F” for non-stationary sources, as well as
equivalent continuous sound-pressure levels determined with a specified integration time for stationary
sources. A-weighted and C-weighted values are obtained from octave-band measurements in the
frequency range from 63 Hz to 8 kHz. The corresponding single number values are detailed in Annex D.
NOTE 1 Time weighting “F” is likely to lead to measurement results less reproducible than time weighting “S”.
NOTE 2 Octave band levels are also used to determine the so-called NC, NR or RC ratings, as described in many
standards. This is especially the case for buildings such as offices, commercial buildings, schools and performance
spaces.
In all cases, normalization to a reference equivalent absorption area or standardization to a reference
reverberation time can be applied.

4.2.2 Relation between quantities
The above sound pressure levels depend on the applied time weighting, i.e. “S”, “F” or integration over a
cycle (equivalent). The levels with these various time weightings depend on the type of sound and cannot
be deduced from each other in general.
In all cases there is a direct relation between the sound pressure level (L ), the normalized sound pressure
p
level (L ) and the standardized sound pressure level (L ) in frequency bands. These relations are given

T is the reverberation time in the room, in seconds;
T is the reference reverberation time (T = 0,5 s for dwellings), in seconds;
0 0

In this document the normalized sound pressure level L is chosen as the prime quantity to predict and
n
noted L (“e” for equipment) instead of L usually used for impact sound level. The other quantities can
ne n
be obtained from this directly, particularly the sound pressure level L (to be compared to measured
p
values) obtained using Formula (1), knowing the equivalent absorption area of the room, where the
measurements have been performed.
4.3 Quantities to express product performances (input quantities)
4.3.1 General
The quantities to express the performance of products relate on the one hand to the sources of sound and
on the other hand to the transmission of sound. In general, this concerns both airborne and structure-
borne sound.
4.3.2 Sources of sound
In the case of airborne sound sources, the basic quantity to express the source strength is the airborne
sound power level, measured according to the standards specified in 4.1.
In the case of structure-borne sound sources, the basic quantity to express the source strength is the
installed power level (and sometimes the blocked force level); these quantities are defined and their
measurement is specified in EN 15657, which so far, is restricted to steady-state vibrating sources. Quasi-
stationary sources, i.e. stationary within the time window chosen for its duration, and more generally
non-stationary sources must be predicted with care, following the information given in Annex D.
If different operating stages are identified in the time response of a given equipment, each stage shall be
studied separately, each considered as an independent source.

SIST EN 12354-5:2023
EN 12354-5:2023 (E)
The relevant sound sources differ for the various equipment and installations considered. Therefore, the
relevant quantities to express the performance of sound sources will be dealt within the appropriate
sections. However, the quantities for the source shall in all cases relate to the same time weighting as the
quantity to be estimated for the building performances.
4.3.3 Transmission of sound
The basic quantities to express the transmission of airborne, impact and service equipment sound are
defined in EN ISO 12354-1 and EN ISO 12354-2, as well as in EN ISO 10848-1, which also specifies the
measurement methods for flanking transmission. These quantities as well as the prediction methods
themselves used in this standard, are defined from and based on the SEA approach, which theoretically
only allows predicting sound in stationary or quasi-stationary situations; for the other cases, follow
Annex D.
5 Calculation models
5.1 General principles
In general, a mixture of airborne and structure-borne sound transmission causes the sound level in a
room due to service equipment. Which of those is dominant, depends on the type of equipment and
installation as well as on the type of building construction. Furthermore, service equipment and
installations often consist of several sound sources and several connection points between the
installation and the building structure. This makes a general prediction method rather complicated.
It is assumed that a complete installation can be divided in several airborne and/or structure-borne
sound elementary sources that can be considered independent from each other. The model approach is
to consider one such an elementary source at the time and one operating stage at the time if several stages
are identified (see 4.3.2). The resulting sound pressure level in a room follows from the sum of the
contribution of each of such elementary sources.
In general, two principally different transmission situations are considered:
— airborne sound transmission through a building construction;
— structure-borne sound transmission through a building construction.
For each of these situations a general approach will be described in the next subclauses. The most
appropriate applications of these general models are specified for several types of service equipment and
installations in Clause 6.
The resulting normalized sound pressure level in a room in frequency bands, L’ , for the considered
ne
installation can therefore be written:

N is the number of elementary airborne sound sources composing the considered
a
installation;
N is the number of elementary structure-borne sound sources composing the considered
s
installation.
NOTE The receiver, not explicitly mentioned here, is noted using subscript “element i” in the text.
In case the source and the building performance are to be expressed by maximum levels, the results
from Formula (3) can be considered as an estimate of the upper limit (all events assumed simultaneous).
An estimate of the lower limit would then be the maximum value of all the sources considered separately
(all events occurring at different times).
The models can be used to calculate the building performance in frequency bands, based on acoustic data
for the sound sources and building elements in frequency bands. From these frequency dependent
performances, the single number rating for the building performance (A- or C-weighting) can be deduced
similarly as for the measurement results in accordance with EN ISO 16032 and EN ISO 10052.
The models assume a diffuse sound field in the source and receiving rooms. Though often a sufficiently
realistic assumption, large deviations may occur at low frequencies. Since sound from some service
equipment will be dominated by low frequencies, such deviations cannot be neglected. Special attention
will be given to this aspect for the application of the models to specific service equipment and installations
(see Clause 6). General information on this aspect is given in Annex B.
Calculation examples are given in the informative Annex G, including calculation examples of Single

European foreword
This document (prEN 12354-5:2022) has been prepared by Technical Committee CEN/TC 126
“Acoustic properties of building elements and of buildings”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12354-5:2009.
EN 12354-5:2009 has been revised in order to extend its application to any type of constructions
(heavy or lightweight) and to better predict low frequencies down to 50 Hz. The document has
therefore been deeply restructured. The application clause, which considers all the different equipment
types and their particularities has been kept and restructured.

1 Scope
This document describes calculation models to estimate the sound pressure level in buildings due to
service equipment. As for the field measurement documents (EN ISO 16032 for the engineering method
and EN ISO 10052 for the survey method), it covers sanitary installations, mechanical ventilation,
heating and cooling, service equipment, lifts, rubbish chutes, boilers, blowers, pumps and other
auxiliary service equipment, and motor driven car park doors, but can also be applied to others
equipment attached to or installed in buildings. The estimation is generally based on measured data
that characterizes both the equipment (source) and the sound transmission through the building. The
same equipment can be composed of different airborne and/or structure borne sources at different
locations in the building; the standard gives some information on these sources and how they can be
characterized; however, models of the equipment itself are out of the scope of this standard.
This document describes the principles of the calculation models, lists the relevant input and output
quantities and defines its applications and restrictions. The models given are applicable to calculations
in frequency bands. It is intended for acoustical experts and provides the framework for the
development of application documents and tools for other users in the field of building construction,
considering local circumstances.
The calculation models described use the most general approach for engineering purposes, with a link
to measurable input quantities that specify the performance of building elements and equipment.
However, it is important for users to be aware that other calculation models also exist, each with their
own applicability and restrictions.
The models are based on experience with predictions for dwellings and offices; they could also be used
for other types of buildings provided the dimensions of constructions are not too different from those in
dwellings.

3 Terms and definitions
No terms and definitions are listed in this document.
4 Relevant quantities
4.1 General
This document describes calculation models to estimate the sound pressure level in buildings due to
service equipment. The output data of the models correspond to quantities expressing the building
performance (sound pressure levels in rooms generated by the equipment installed in the building), as
the input data correspond to quantities expressing the product performances for both the source(s) of
sound (the equipment itself) and the building elements involved in the transmission of sound.
In this standard, the output quantities are determined, like in EN ISO 12354-1 and EN ISO 12354-2, in
1/3 octave bands at least in the frequency range 100-3150 Hz, possibly extended down to
1/3 octave 50 Hz if building element data and junction data involved in the transmission of sound are
available, and up to 5 kHz, particularly for airborne sound quantities. Service equipment performance
data are based on measurements according to EN 15657 where measurements are performed in
1/3 octave bands in the frequency range 50–3150 Hz. However, for some service equipment, the
frequency range of interest won’t cover this complete range.
NOTE For measuring airborne sound power of equipment in reverberant conditions, EN 15657:2017 refers
to EN ISO 3740 to EN ISO 3747, in which only limited information can be found for measurements performed in
small reverberant rooms, down to 50 Hz, in 1/3 octave band and applied to non-stationary sources, as well as for
their accuracy. Nevertheless, the measurement procedure is fully given in the standardized application documents
focused on laboratory measurements for each type of service equipment (for example, in EN 14366-1 for waste
water pipes).
4.2 Quantities to express building performances (output quantities)
4.2.1 General
This standard aims at predicting sound pressure levels in buildings and comparing results to values
measured in situ. Field measurements of sound from equipment and machinery are performed
according to EN ISO 16032 (engineering method) or EN ISO 10052 (survey method) with results
expressed in terms of sound pressure level in various ways: maximum A-weighted and optionally C-
weighted sound-pressure levels using time weighting “ S” or time weighting “ F” for non-stationary
sources, as well as equivalent continuous sound-pressure levels determined with a specified integration
time for stationary sources. A-weighted and C-weighted values are obtained from octave-band
measurements in the frequency range from 63 Hz to 8 kHz. The corresponding single number values
are detailed in Annex D.
NOTE 1 Time weighting “F” is likely to lead to measurement results less reproducible than time weighting “S”.
NOTE 2 Octave band levels are also used to determine the so-called NC, NR or RC ratings, as described in many
standards. This is especially the case for buildings such as offices, commercial buildings, schools and performance
spaces.
In all cases, normalization to a reference equivalent absorption area or standardization to a reference
reverberation time can be applied.
4.2.2 Relation between quantities
The above sound pressure levels depend on the applied time weighting, i.e. “ S ”, “ F ” or integration over
a cycle (equivalent). The levels with these various time weightings depend on the type of sound and
cannot be deduced from each other in general.

In all cases there is a direct relation between the sound pressure level (L ), the normalized sound

In this document the normalized sound pressure level L is chosen as the prime quantity to predict and

noted L (“e” for equipment) instead of L usually used for impact sound level. The other quantities can

be obtained from this directly, particularly the sound pressure level L (to be compared to measured
p
values) obtained using Formula (1a), knowing the equivalent absorption area of the room, where the
measurements have been performed.
4.3 Quantities to express product performances (input quantities)
4.3.1 General
The quantities to express the performance of products relate on the one hand to the sources of sound
and on the other hand to the transmission of sound. In general, this concerns both airborne and
structure-borne sound.
4.3.2 Sources of sound
In the case of airborne sound sources, the basic quantity to express the source strength is the airborne
sound power level, measured according to the standards specified in 4.1.
In the case of structure-borne sound sources, the basic quantity to express the source strength is the
installed power level (and sometimes the blocked force level); these quantities are defined and their
measurement is specified in EN 15657, which so far, is restricted to steady-state vibrating sources.
Quasi-stationary sources, i.e. stationary within the time window chosen for its duration, and more
generally non-stationary sources must be predicted with care, following the information given
in Annex D.
If different operating stages are identified in the time response of a given equipment, each stage shall be
studied separately, each considered as an independent source.
The relevant sound sources differ for the various equipment and installations considered. Therefore,
the relevant quantities to express the performance of sound sources will be dealt within the
appropriate sections. However, the quantities for the source shall in all cases relate to the same time
weighting as the quantity to be estimated for the building performances.

4.3.3 Transmission of sound
The basic quantities to express the transmission of airborne, impact and service equipment sound are
defined in EN ISO 12354-1 and EN ISO 12354-2, as well as in EN ISO 10848-1, which also specifies the
measurement methods for flanking transmission. These quantities as well as the prediction methods
themselves used in this standard, are defined from and based on the SEA approach, which theoretically
only allows predicting sound in stationary or quasi-stationary situations; for the other cases, follow
Annex D.
5 Calculation models
5.1 General principles
In general, a mixture of airborne and structure-borne sound transmission causes the sound level in a
room due to service equipment. Which of those is dominant, depends on the type of equipment and
installation as well as on the type of building construction. Furthermore, service equipment and
installations often consist of several sound sources and several connection points between the
installation and the building structure. This makes a general prediction method rather complicated.
It is assumed that a complete installation can be divided in several airborne and/or structure-borne
sound elementary sources that can be considered independent from each other. The model approach is
to consider one such an elementary source at the time and one operating stage at the time if several
stages are identified (see 4.3.2). The resulting sound pressure level in a room follows from the sum of
the contribution of each of such elementary sources.
In general, two principally different transmission situations are considered:
— airborne sound transmission through a building construction;
— struc
