Sound Immission Forecast
Modelling of sound propagation with consideration of turbines, operating modes, terrain and receptors.
Emissions: Sound, Shadow Flicker & Ice
Identify environmental effects early
We assess project- and site-specific effects from sound, periodic shadow flicker, ice fall and ice throw and develop robust planning and operating options.
The objective
Identify environmental effects early
Emissions are integral to a project: they affect approval, wind-farm layout, operation and acceptance. An integrated assessment reveals competing objectives and creates a common basis for planning, communication with authorities and operation.
Soundassess immission levels transparently
Shadowdetermine exposure times by location
Iceevaluate risks and safeguards
Scope of services
Turning complexity into clarity.
We combine the modules to suit the project phase, from a focused individual assessment to an integrated analysis.
Existing and Total Exposure
Assessment of existing and planned sources to provide a realistic view of the combined effect.
Shadow Flicker Forecast
Determination of potential and expected exposure times at relevant receptors over the course of a year.
Shutdown Concepts
Development of transparent operating strategies to meet project-specific requirements.
Ice Fall & Ice Throw
Site- and turbine-specific risk assessment for transport routes, work areas and sensitive uses.
Protective Measures
Assessment of detection, shutdown, restart, signage and organisational measures as an integrated concept.
Project process
A structured path from data to results.
Identify Sensitive Receptors
Receptors, routes, uses, existing exposure and project-specific requirements are recorded in full.
Calculate Scenarios
We model relevant turbine configurations, operating modes and meteorological conditions.
Assess Effects
Results are evaluated spatially and over time, with uncertainties and competing objectives shown transparently.
Develop Measures
Together we develop proportionate planning and operating options for the specific project.
What you receive
Results you can put to work.
- Transparent forecasts with clearly documented assumptions
- Maps, receptor locations and time-based evaluations
- Comparison of layout and operating-mode variants
- Project-specific mitigation and protective measures
Input data
What we need to get started
- Coordinates, turbine types, hub heights and operating modes
- Receptors, transport routes and sensitive uses
- Information on existing exposure and other sources
- Terrain, weather and project-specific permitting data
Missing data is not an obstacle. We identify gaps early and agree appropriate substitute assumptions or additions with you.
Frequently asked questions
Brief answers.
Should sound, shadow flicker and ice be assessed together?
Yes, at least during variant planning. Measures in one area can affect yield, loads or other environmental effects. An integrated view prevents competing objectives from emerging later.
Can existing wind farms be reassessed?
Yes. Reasons may include new neighbouring turbines, changed operating modes, complaints, repowering or the optimisation of existing protection concepts.
Are shutdowns always the only solution?
No. Depending on the issue, options include layout adjustments, operating modes, sectoral or time-based control, monitoring and organisational measures.
