Building acoustics - Estimation of acoustic performance of building from the performance of elements - Part 5: Sounds levels due to service equipment
This document describes calculation models to estimate the sound pressure level in buildings due to service equipment. As for the field measurement document (EN ISO 16032) 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 primarily based on measured data that characterizes both the sources and the building constructions. The models given are applicable to calculations in frequency bands. This document describes the principles of the calculation models, lists the relevant quantities and defines its applications and restrictions. 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, taking into account local circumstances. The calculation models described use the most general approach for engineering purposes, with a link to measurable quantities that specify the performance of building elements and equipment. The known limitations of these calculation models are described in this document. Users should, however, 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.

Die Berechnung basiert vorrangig auf Messdaten, die sowohl die Schallquellen als auch die Gebäudekonstruktionen kennzeichnen. Die angegebenen Modelle sind für Berechnungen in Frequenzbändern anwendbar.
Das vorliegende Dokument beschreibt die Grundlagen der Berechnungsmodelle, führt die entsprechenden Größen auf und legt ihre Anwendung sowie geltende Einschränkungen fest. Das Dokument bietet Akustik Fachleuten einen Rahmen zur Erstellung von Dokumenten und Hilfsmitteln, die von anderen Anwendern im Bereich Bauausführung unter Berücksichtigung der örtlichen Gegebenheiten genutzt werden.
Die Berechnungsmodelle beschreiben die Anwendung der für technische Zwecke gebräuchlichsten Methode unter Verweis auf messbare Größen, die der Festlegung der Eigenschaften von Bauteilen und Ausrüstungs¬gegenständen dienen. In diesem Dokument werden auch die bekannten Grenzen dieser Berechnungsmodelle angegeben. 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 Modelle berufen sich auf die Erfahrungen, die bei Voraussagen für Wohnungen und Büroräume gewonnen wurden; sie können auf andere Gebäudearten unter der Voraussetzung übertragen werden, dass die Maße dieser Gebäude nicht wesentlich von den Maßen der Wohnungen abweichen.
Acoustique du bâtiment - Calcul de la performance acoustique des bâtiments a partir de la performance des éléments - Partie 5: Niveaux sonores dus aux équipements du bâtiment
Le présent document décrit des modèles de calcul pour estimer le niveau de pression acoustique dans les bâtiments dû aux équipements techniques. Comme le document de mesurage sur site (EN ISO 16032), 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 soufflants, les pompes et autres équipements techniques auxiliaires et les portes de garage motorisées. Il peut aussi s’appliquer à d’autres équipements fixés aux bâtiments ou installés dans ceux-ci. L’estimation est principalement basée sur des données mesurées qui caractérisent les sources et les structures des bâtiments. Les modèles présentés sont applicables à un calcul par bandes de fréquences.
Le présent document décrit les principes des modèles de calcul, énumère les grandeurs significatives et définit les applications et les limites de ces modèles. Il est destiné aux experts en acoustique et fournit un cadre de développement de documents applicatifs et d’outils destinés à d’autres utilisateurs dans le domaine du bâtiment, tenant compte de conditions locales.
Les modèles de calcul décrits utilisent l’approche la plus générale pour les besoins d’ingénierie avec un lien avec des grandeurs mesurables spécifiant les performances des éléments et équipements du bâtiment. Les limitations connues de ces modèles de calcul sont décrites dans la présente norme. Il convient de savoir, toutefois, 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 prédiction pour des bâtiments d’habitation et des bureaux ; ils peuvent aussi être utilisés pour d’autres types de bâtiments, dans la mesure où les dimensions constructives sont similaires à celles des habitations.

EN 12354-5:2009 (E) 4 Foreword This document (EN 12354-5:2009) 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 European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by October 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document is the first version of a standard, which forms a part of a series of standards specifying calculation models in building acoustics: Part 1: Building Acoustics Estimation of acoustic performance of buildings from the performance of elements Part 1: Airborne sound insulation between rooms. Part 2: Building Acoustics Estimation of acoustic performance of buildings from the performance of elements Part 2: Impact sound insulation between rooms. Part 3: Building Acoustics Estimation of acoustic performance of buildings from the performance of elements Part 3: Airborne sound insulation against outdoor sound. Part 4: Building Acoustics Estimation of acoustic performance of buildings from the performance of elements Part 4: Transmission of indoor sound to the outside. Part 5: Building Acoustics Estimation of acoustic performance of buildings from the performance of elements Part 5: Sound levels due to the service equipment. Part 6: Building Acoustics Estimation of acoustic performance of buildings from the performance of elements Part 6: Sound absorption in enclosed spaces. Although this part covers the most common types of service equipment and installations in buildings, it cannot as yet cover all types and all situations. It sets out an approach for gaining experience for future improvements and developments. The accuracy of this standard can only be specified in detail after widespread comparisons with field data, which can only be gathered over a period of time after establishing the prediction model. To help the user in the mean time, indications of the accuracy have been given, based on earlier comparisons with comparable prediction models. It is the responsibility of the user (i.e. a person, an organisation, the authorities) to address the consequences of the accuracy, inherent for all measurement and prediction methods, by specifying requirements for the input data and/or applying a safety margin to the results or applying some other correction. Annex A forms an integral part of this part of EN 12354. Annexes B, C, D, E, F, G and H are for information only. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. SIST EN 12354-5:2009
EN 12354-5:2009 (E) 5 Introduction The estimation of sound levels due to service equipment in buildings is a complex task and structure-borne sources and transmission are not completely understood. In addition there are large variations between different equipment and installations and an installation often results in both airborne and structure-borne sources. This document contains a framework within which this subject can be treated. The main part (Clause 4) describes general models for sound transmission and related sources for ducts, airborne sound through buildings and structure-borne sound through buildings. For airborne and structure-borne sound transmission, parts 1 and 2 of EN 12354 are used wherever possible. In Clause 5 the application of these models to the different types of service equipment in buildings is addressed, specifying what is already known and available and what is not. Informative annexes give additional information on various aspects, related to sources and their sound production as well as to specific aspects of sound transmission through buildings. Wherever possible references are made to available handbooks, literature or ongoing standardization work. Over the course of time some annexes or parts of them, especially those relating to the sound production by sources, can be deleted when appropriate standards become available. For sound transmission through ducts there are standardized methods available to determine the sound power level of sources or the transmission loss of elements. Various handbooks are widely used for these estimations. For airborne sound transmission through buildings information exists about sources and transmission, but some aspects that are particularly relevant to service equipment are less well known, such as the effect of acoustic near-fields, non-diffuse spaces and excitation and transmission at low frequencies. For these aspects some indications are given as to how they could be treated and also as an indicator for the direction of further research and future improvements to the models. For structure-borne sound transmission similar solutions and problems exist as used for airborne sound. However, here the appropriate methods to characterize the sources for structure-borne sound excitation are just starting to become available, largely due to standardization work started within CEN (TC126/WG7) Therefore in this document a choice has been made to use a general quantity in the models, called "the characteristic structure-borne sound power level" of sources, even though there is no practical measurement method available at the moment. This allows the estimation models to have a general form that could be developed and refined in the future. For some types of equipment indications are given in an informative annex as to how this quantity can be deduced or estimated from available and current measurement methods, such as the ones already developed within CEN. The aim of this document is to provide a general basis for a practical approach to the estimation of sound levels due to service equipment. It also clarifies the need for work on source characterisation with an indication of areas where further research work is needed. SIST EN 12354-5:2009
EN 12354-5:2009 (E) 6 1 Scope This document describes calculation models to estimate the sound pressure level in buildings due to service equipment. As for the field measurement document (EN ISO 16032) 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 primarily based on measured data that characterises both the sources and the building constructions. The models given are applicable to calculations in frequency bands. This document describes the principles of the calculation models, lists the relevant quantities and defines its applications and restrictions. 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, taking into account local circumstances. The calculation models described use the most general approach for engineering purposes, with a link to measurable quantities that specify the performance of building elements and equipment. The known limitations of these calculation models are described in this document. Users should, however, 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 constructional dimensions are similar to those in dwellings. 2 Normative references The following referenced documents are indispensable for the application of this document.

These quantities are determined in octave bands as maximum level using time weighting "S" or time weighting "F" or as equivalent level; in all cases normalization to a reference equivalent absorption area or standardization to a reference reverberation time can be applied. The building performance is normally expressed in an A-weighted or C-weighted sound pressure level that is to be calculated from these octave band levels. NOTE The octave band levels are also used to determine the so-called NC, NR or RC ratings, as described in many textbooks. This is especially the case for buildings such as off

Predgovor
Ta dokument (EN 12354-5:2009) je pripravil tehnični odbor CEN/TC 126 Akustične lastnosti gradbenih
proizvodov in stavb, katerega sekretariat vodi AFNOR.
Ta evropski standard mora dobiti status nacionalnega standarda bodisi z objavo istovetnega besedila
ali z razglasitvijo najpozneje oktobra 2009, nasprotujoče nacionalne standarde pa je treba razveljaviti
najpozneje oktobra 2009.
Opozoriti je treba na možnost, da so lahko nekateri elementi tega standarda predmet patentnih pravic.
CEN (in/ali CENELEC) ne prevzemata odgovornosti za identifikacijo katerih koli ali vseh takih
patentnih pravic.
Ta standard je prva izdaja standarda, ki ga sestavlja skupina standardov, ki določajo modele
izračunov akustike v stavbah:
– 1. del: Akustika v stavbah – Ocenjevanje akustičnih lastnosti stavb iz lastnosti sestavnih delov –
1. del: Izolirnost pred zvokom v zraku med prostori
– 2. del: Akustika v stavbah – Ocenjevanje akustičnih lastnosti stavb iz lastnosti sestavnih delov –
2. del: Izolirnost pred udarnim zvokom med prostori
– 3. del: Akustika v stavbah – Ocenjevanje akustičnih lastnosti stavb iz lastnosti sestavnih delov –
3. del: Izolirnost pred zvokom v zraku iz zunanjosti
– 4. del: Akustika v stavbah – Ocenjevanje akustičnih lastnosti stavb iz lastnosti sestavnih delov –
4. del: Prenos zvoka iz notranjosti v okolico
– 5. del: Akustika v stavbah – Ocenjevanje akustičnih lastnosti stavb iz lastnosti sestavnih delov –
5. del: Zvočne ravni obratovalne opreme
– 6. del: Akustika v stavbah – Ocenjevanje akustičnih lastnosti stavb iz lastnosti sestavnih delov –
6. del: Absorpcija zvoka v zaprtih prostorih
Čeprav ta del zajema najpogostejše vrste obratovalne opreme in namestitve v stavbah, doslej ne
more zajeti vseh vrst in vseh primerov. Določa pot za pridobivanje izkušenj za izboljšave in razvoj v
prihodnje.
Točnost tega standarda se lahko podrobno določi šele s široko primerjavo podatkov s terena, ki se
lahko zberejo šele po daljšem času po uvedbi modela za napovedovanje. V vmesnem času so
uporabnikom v pomoč navedbe o točnosti, ki temeljijo na prejšnjih primerjavah s primerljivimi modeli
za napovedovanje. Odgovornost uporabnika (tj. osebe, organizacije, uradne osebe) je, da opozori na
posledice točnosti, povezane z merilnimi postopki ali metodami napovedovanja, s tem, da določi
zahteve za vhodne podatke in/ali navede varne meje rezultatov ali uporabi nekatere druge popravke.
Dodatek A je sestavni del tega dela EN 12354, dodatki B, C, D, E in F, G in H so le informativni.
Po določilih notranjih predpisov CEN/CENELEC so ta evropski standard dolžne privzeti nacionalne
organizacije za standarde naslednjih držav: Avstrije, Belgije, Bolgarije, Cipra, Češke republike,
Danske, Estonije, Finske, Francije, Grčije, Islandije, Irske, Italije, Latvije, Litve, Luksemburga,
Madžarske, Malte, Nizozemske, Nemčije, Norveške, Poljske, Portugalske, Romunije, Slovaške,

SIST EN 12354-5 : 2009
Uvod
Ocenjevanje ravni hrupa zaradi obratovalne opreme v stavbah je zapletena naloga ter strukturnega
zvoka in prevajanja ni mogoče v celoti razumeti. Poleg tega so velike razlike med različno opremo ter
namestitvami in je določena namestitev pogosto vir obeh, zvoka v zraku in strukturnega zvoka. Ta
dokument vsebuje okvir za možno obravnavanje te teme. Glavni del (točka 4) opisuje splošne modele
prevajanja zvoka ter pripadajoče vire za kanale in za zvok v zraku in strukturni zvok skozi stavbo. Za
prevajanje zvoka v zraku in strukturnega zvoka se uporabljata dela 1 in 2 EN 12354, kjerkoli je to
mogoče.
Točka 5 je namenjena uporabi teh modelov za različne vrste obratovalne opreme in stavb in navaja,
kaj je že znanega ter je na voljo, in česa ni. Informativni dodatki dajejo dodatna pojasnila z različnih
vidikov, ki se nanašajo na vire in njihovo proizvajanje zvoka, kot tudi posebne vidike prevajanja zvoka
skozi stavbo. Kjer je to mogoče, so navedeni napotki na razpoložljive priročnike, literaturo ali pripravo
standardov. Sčasoma bodo lahko nekateri dodatki ali njihovi deli izbrisani, posebno tisti, ki se
nanašajo na nastajanje zvoka virov, ko bodo na voljo ustrezni standardi.
Za prevajanje zvoka skozi kanale so na voljo standardizirane metode za določanje zvočne moči virov
ali prenosnih izgub elementov. Za ocenjevanje se obširno uporabljajo različni priročniki.
Za prevajanje zvoka v zraku skozi stavbo obstajajo pojasnila o virih in prevajanju, vendar so nekateri
pojavi, ki so posebno pomembni v zvezi z obratovalno opremo, manj znani, kot so to vpliv bližnjega
zvočnega polja, nedifuzni pojavi ter vzbujanje in prevajanje pri nizkih frekvencah. Za te pojave so
podane nekatere indikacije, na kakšen način se lahko obravnavajo, in tudi možne usmeritve kot
indikacija za nadaljnje raziskave in prihodnje dopolnitve metod.
Za prevajanje strukturnega zvoka obstajajo podobni problemi in rešitve, kot se uporabljajo za zvok v
zraku. Vendar se primerne metode za podrobni opis virov in vzbujanja strukturnega zvoka šele
pričenjajo uveljavljati, večinoma znotraj CEN (TC 128/WG7) z delom na področju standardizacije. Zato
je bila v tem dokumentu v modelih izbrana uporaba splošne veličine, imenovane »karakteristična
raven moči strukturnega zvoka« virov, celo tistih, za katere trenutno ni na voljo praktične merske
metode. To dovoljuje splošno obliko za ocenjevalne modele, ki bodo lahko v prihodnje razviti in
izboljšani. Za nekatere vrste opreme so podana pojasnila v informativnih dodatkih o tem, kako se ta
veličina lahko izvede ali oceni iz razpoložljivih ali obstoječih merskih metod, kot so jih že razvili v CEN.
Namen tega dokumenta je zagotoviti splošni temelj za praktično približevanje k ocenjevanju ravni
zvoka zaradi obratovalne opreme. Razjasnjuje tudi potrebo po delu pri karakterizaciji virov z označbo
področij, na katerih so potrebne nadaljnje raziskave.

1 Področje uporabe
Ta dokument opisuje računske modele za izračun ravni zvočnega tlaka v stavbah zaradi obratovalne
opreme. Kot dokument, ki obravnava meritve na terenu (EN 16032), se nanaša na sanitarne
inštalacije, mehansko prezračevanje, ogrevanje in hlajenje, obratovalno opremo, dvigala, jaške za
smeti, kotle, ventilatorje, črpalke in drugo pomožno obratovalno opremo ter parkirna vrata na
mehaniziran pogon za avtomobile, vendar se lahko uporablja tudi za drugo pritrjeno ali vgrajeno
opremo v stavbi. Računanje temelji predvsem na merskih podatkih, ki so značilni tako za vir hrupa kot
za konstrukcijo stavbe. Opisani modeli so uporabni za računanje po frekvenčnih pasovih.
Ta dokument opisuje načela računskih modelov, navaja relevantne veličine in opredeljuje nji

Foreword
This document (prEN 12354-5:2007) 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 is the first version of a standard, which forms a part of a series of standards specifying calcula-
tion models in building acoustics:
Part 1: Building Acoustics Estimation of acoustic performance of buildings from the performance of
elements Part 1: Airborne sound insulation between rooms.
Part 2: Building Acoustics Estimation of acoustic performance of buildings from the performance of
elements Part 2: Impact sound insulation between rooms.
Part 3: Building Acoustics Estimation of acoustic performance of buildings from the performance of
elements Part 3: Airborne sound insulation against outdoor sound.
Part 4: Building Acoustics Estimation of acoustic performance of buildings from the performance of
elements Part 4: Transmission of indoor sound to the outside.
Part 5: Building Acoustics Estimation of acoustic performance of buildings from the performance of
elements Part 5: Sound levels due to service equipment.
Part 6: Building Acoustics Estimation of acoustic performance of buildings from the performance of
elements Part 6: Sound absorption in enclosed spaces.
Although this part covers the most common types of service equipment and installations in buildings, it cannot
as yet cover all types and all situations. It sets out an approach for gaining experience for future improvements
and developments.
The accuracy of this standard can only be specified in detail after widespread comparisons with field data,
which can only be gathered over a period of time after establishing the prediction model. To help the user in
the mean time, indications of the accuracy have been given, based on earlier comparisons with comparable
prediction models. It is the responsibility of the user (i.e. a person, an organisation, the authorities) to address
the consequences of the accuracy, inherent for all measurement and prediction methods, by specifying
requirements for the input data and/or applying a safety margin to the results or applying some other
correction.

Introduction
The estimation of sound levels due to service equipment in buildings is a complex task and structure-borne
sources and transmission are not completely understood. In addition there are large variations between
different equipment and installations and an installation often comprises both airborne and structure-borne
sources. This document contains a framework within which this subject can be treated. The main part (chapter
4) describes general models for the sound transmission and the related sources for ducts, airborne sound
through buildings and structure-borne sound through buildings. For airborne and structure-borne sound
transmission parts 1 and 2 of EN 12354 are used wherever possible.
In clause 5 the application of these models to the different types of service equipment in buildings is treated,
specifying what is already known and available and what is not. In several annexes additional information is
given on various aspects, related to sources and their sound production as well as to specific aspects of
sound transmission through buildings.
For sound transmission through ducts there are standardized methods available to determine the sound
power level of sources or the transmission loss of elements. Various handbooks are widely used for these
estimations.
For airborne sound transmission through buildings there is existing information about sources and
transmission, but some aspects that are particularly relevant to service equipment are less well known, such
as the effect of acoustic near-fields, non-diffuse spaces and excitation and transmission at low frequencies.
For these aspects some indications are given as to how they could be treated and also as an indicator for the
direction of further research and future improvements to the models.
For structure-borne sound transmission similar solutions and problems exist as used for airborne sound.
However, here the appropriate methods to characterize the sources for structure-borne sound excitation are
not available, although there are various proposals in the literature and work has started within CEN
(TC126/WG 7) Therefore in this document a choice has been made to use a general quantity in the models,
called "the characteristic structure-borne sound power level" of sources, even though there is no practical
measurement method available at the moment. This allows the estimation models to have a general form that
could be developed and improved in the future. For some types of equipment indications are given in an
informative annex as to how this quantity can be deduced or estimated from available and current
measurement methods, like the ones already proposed by WG 7.
The aim of this document is to provide a general basis for a practical approach to the estimation of sound
levels due to service equipment. It also clarifies the need for work on source characterisation with an
indication of areas where further research work is needed.

1 Scope
This document describes calculation models to estimate the sound pressure level in buildings due to service
equipment. As for the field measurement document (EN ISO 16032) 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 primarily based on measured data that
characterises both the sources and the building constructions. The models given are applicable to calculations
in frequency bands.
This document describes the principles of the calculation models, lists the relevant quantities and defines its
applications and restrictions. 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, taking into
account local circumstances.
The calculation models described use the most general approach for engineering purposes, with a link to
measurable quantities that specify the performance of building elements and equipment. The known
limitations of these calculation models are described in this document. Users should, however, 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.
