Because of their potential noise and shadow flicker impact on sensitive areas, wind park projects usually require an approval according to country-specific legislations. In Germany details are determined by the Federal Immission Control Act (BImschG, "Bundesimmissionsschutzgesetz") and the related technical instructions on protection against noise "TA-Lärm" as well as the recommendations of the Federal States Committee for Immissions "LAI".
Services in detail
- site visit (project site and immission points)
- evaluation / determination of relevant immission points (usually in agreement with local authorities)
Prediction of noise immission according to TA-Lärm / DIN ISO 9613-2
- assessment of new and already existing wind turbines and their sound power levels
- evaluation of previous impacts by commerical/industrial buildings, obtaining of land utilization and/or building plans, consideration of country/state legislations
- sound propagation calculation acc. to DIN ISO 9613-2 (e.g., WindPRO Module Decibel) for the long-range area of the site. Presentation of the previous, additional and total impacts as well as partial noise rating levels at the relevant immission points, comparison with guideline values
- Report/Expertise: Presentation of all results and methods, quality of the prediction, detailed uncertainty documentation (ensurement not to exceed the guideline values, calculation of 90 % confidence levels)
Prediction of shadow flicker according to LAI
- calculation of the astronomic maximum possible (worst case) and meteorologically probable (real case) shadow flicker at the immission points (e.g., WindPRO Module Shadow)
- creation of shadow flicker maps (previous, additional and total impact) for the surrounding of the project site
- recommendation of measures to minimize the immissions by shadow flicker (e.g., shut down modules for single wind turbines), determination of shut down periods
- Expertise/report: presentation of all results and methods in report form
