Building acoustics - Estimation of acoustic performance of building from the performance of elements - Part 5: Sounds levels due to the service equipment; English version of DIN EN 12354-5:2009-10
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.
