The Wind zone describes how strongly the wind blows on average at a site. According to DIN EN 1991-1-4 with national annex, Germany is divided into four wind zones – highest on the coast and the islands.
The four wind zones
| Wind zone | Basic wind speed |
|---|---|
| 1 | 22,5 m/s |
| 2 | 25,0 m/s |
| 3 | 27,5 m/s |
| 4 | 30,0 m/s |
The exact assignment is by municipality. Together with building height and Terrain category this gives the Wind load.
What does this mean for window actuators?
In wind zones 3 and 4 and on tall buildings we plan more Reserve (+50 %) and recommend a Wind monitorthat closes open windows in a storm.
