Assessments for BimSchG Approval

Site Suitability

  • Highly resolved wind field simulations with our CFD software WindStation and validation of the wind field using energy yield data and wind measurements
  • Determination of the environmental turbulence intensity from meso-scale data or measurements and a wind field simulation
  • Calculation of the characteristic turbulence intensity according to IEC 61400-1 Edition 2
  • Calculation of the representative turbulence intensity according to IEC 61400-1 Edition 3
  • Evaluation of the effective turbulence intensity at the WEA sites
  • Verification of the site suitability according to the valid IEC 61400 or DIBt guideline

Noise emissions

  • Simulation of noise emissions according to LAI references (interim or alternative method) with the WindPRO module NOISE
  • Consideration of noise level data incl. octave band data for different operational modes
  • Determination of the upper confidence limit (uncertainty analysis)
  • Conduct of a site visit
  • Communication with the local BImSchG authorities

Shadow flicker

  • Simulation of shadow flicker according to LAI references
  • Determination of the astronomical maximum of shadow flicker as well as the meteorological shadow flicker using the WindPRO module SHADOW
  • Conduct of a site visit
  • Communication with the local BImSchG authorities

Optical harassment of wind turbines and Visualizations

  • Simulation of the visibility of the wind turbine with the WindPRO module ZVI
  • Generation of photomontages using the WindPRO module VISUALIZE
  • Consideration of current law
  • Evaluation of the optical harassment considering distance regulations, sight restrictions, plants, terrain, existing wind turbines, use of living area
