Description
The calculation method to predict noise from building service equipment according to EN 12354-5 has seen significant improvements and gained acceptance in recent years. In some countries (e.g. Germany), it is also finding its way into national building regulations as a means to show compliance with requirements. Still, there is more research needed for the prediction of noise from building service equipment to reach the same level of acceptance and usage as the prediction of noise from airborne or impact sound sources. In this contribution, the current situation of prediction methods for noise from building services is reviewed, focusing on technical as well as normative aspects. An overview is provided on the relevant standards (e.g. EN 12354-5, EN 15657, EN ISO 10848) and their relationship. Based on this overview, the needs for future research are identified. These include research questions regarding the sources, the receivers, their coupling, as well as questions concerning the predicted quantities and their uncertainties. A companion contribution by Scheck et al. focuses on characterization methods for noise sources from sanitary installations and the relevant standards (e.g. EN 14366-1, future EN 14366-2, EN ISO 3822).
