Meteodyn EC1
Meteodyn EC1 is a web application for automatic wind load sizing according to Eurocode 1.
It allows you to quickly and easily calculate the peak dynamic pressure exerted on your building in Metropolitan France or in Belgium, in just a few clicks.
Wind load calculation software for structures according to Eurocode 1
An important step in the calculation of wind forces during a storm is the determination of the wind speed at the construction site. This velocity results in pressure exerted on its surfaces.
Le dimensionnement au vent des constructions est régi par l’Eurocode 1 :
« Actions sur les structures » et plus particulièrement la section 4 « Actions du vent ». Il est complété par des Annexes Nationales qui précisent certains paramètres spécifiques au territoire concerné (France, Belgique).
The Meteodyn EC1 web application automatically calculates wind load design for structures in France (including DROM-COM) and Belgique tol’Eurocode 1. It takes into account all the parameters affecting the reference wind speed that sizes structures and locally calculates the peak dynamic pressure and equivalent velocity based on the location, height above ground, roughness and orography, all in one click.
Accurate results, without oversizing, in one click.
Accurate wind data computation
The application automatically determines the parameters necessary for the wind calculation: basic speed, directional coefficient, roughness, orographic coefficient, turbulence intensity…

Strengths
Quick and easy-to-use application
Highly ergonomic, the application only requires the location and the height of interest to perform calculations with a single click.
These results can be viewed directly within the application. The directional results (z0, cdir) and intermediate results (z0, c0) are displayed on the screen. You can also export the entire set in PDF format.
High computation accuracy
Meteodyn EC1 considers the National Annex of Eurocode 1.
Regarding orography, the application incorporates Procedure 1 from clause 4.3.3(1) of the French National Annex, enhancing the accuracy of the results, which are therefore not overestimated.
Orography and roughness from satellite imagery
The roughness comes from the CORINE Land Cover map, produced by visual interpretation of satellite imagery and provided by the European Copernicus program.
