With the introduction of version 3.3.4 wake2e determines the “Windzone” according to DIN EN 1991-1-4/NA and according to “DIBt 2004 Anhang B” for projects in Germany. You will find the results in the section “results → other” of the result file.
This classification is based on raster data of the actual zones. For wind turbines located very close to a border of the zones the classification might be incorrect. In these cases you will receive a warning. In some areas the zone according to “DIBt 2004 Anhang B” could not be assigned without any doubt and two zones will be given as output.
We hope that you will appreciate the new features and we are looking forward to your feedback.
