Development of a concept for the assessment of overall noise

The Ministry of the Environment, Agriculture, Nature Conservation and Consumer Protection of the State of North Rhine-Westphalia in Germany has published a study by the research consortium Möhler + Partner Ingenieure AG and ZEUS GmbH Zentrum für angewandte Psychologie, Umwelt- und Sozialforschung on the subject of overall noise. The study examines the feasibility of an overall noise assessment in terms of noise and immission control and prepares the content of the changes required for implementation. It is available for download here.

Noise impact of infrasound immissions

Within the framework of the research project, our interdisciplinary consortium with Prof. Krahé, the psychologists from ZEUS and the medical scientists from the DLR on behalf of the German Federal Environment Agency (Umweltbundesamt, UBA) investigated the noise impact of infrasound immissions between 2015 and 2019. The study was designed to be independent of actually existing infrasound sources; i.e. we wanted to investigate the impact of infrasound immissions that have a general effect on people in quiet living situations and to consider the psychological and physiological effects of infrasound on people. The project closed a gap in knowledge for the level range of infrasound relevant for immission control, with non-weighted levels of 85 to 120 dB, i.e. the range around the human perception threshold of infrasound. This was necessary also because infrasound is a relatively new topic in immission control and is constantly evolving as a result of various technical and political developments.

 

In order to ensure the practical relevance of the project, the special acoustic properties of infrasound immissions from actually existing sources were simulated as a boundary condition, and test persons were exposed to these acoustic properties under controlled laboratory conditions. This concerns both the controlled laboratory situation (normal and very quiet living situation without disturbances) and the characteristic frequency and time response of technical sources. As a result, it was found that infrasound at or below the perception threshold does not lead to any immediate bodily reactions.

 

The final report of the research project was published at the UBA and can be viewed here.

From 1.11.2020: Building Energy Act replaces EnEG, EnEV and EEWärmeG

After several years of voting, the Building Energy Act (GEG) was passed by the Bundestag and Bundesrat in the course of 2020 and will replace the Energy Saving Act (EnEG), the Energy Saving Ordinance (EnEV) and the Renewable Energies Heat Act (EEWärmeG) as of 1.11.2020.
The version of the GEG published in the Federal Law Gazette on 13.08.2020 contains various changes compared to EnEV and EEWärmeG, but no fundamental tightening of the requirements. The retention of the energy standard according to EnEV 2016 was made possible by a declaration of the previous level of requirements as the lowest energy building according to the EU building directive.
Changes compared to EnEV and EEWärmeG concern, for example, a lower limit and obligation to publish individual primary energy factors, a ban on oil and coal heating systems from 2026 and obligations to provide energy advice when selling and changes to detached and semi-detached houses, but also facilitations such as the improvement of PV systems or the eligibility of biogas in a condensing boiler.
New additions are the alternative proof of greenhouse gas emissions and the neighbourhood approach for changes to existing buildings. The energy standard will be reviewed and further developed in 2023.
