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, 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.
Wind design of structures is governed by the Eurocode 1 standard:
“Actions on Structures” especially Section 4, “Wind Actions”. It is supplemented by its National Annex, which specifies certain parameters specific to France.
The Meteodyn EC1 web application automatically calculates the wind design of structures in Metropolitan France (excluding Corsica and Overseas Departments and Territories) according to 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…

and data considered in Meteodyn EC1
Quick and easy-to-use application
These results can be viewed directly within the application. The intermediate results are accessible in a collapsible panel. Finally, directional results (roughness and directional coefficient) are displayed when hovering the mouse pointer over the relevant sector.
High computation accuracy
As for orography, the application incorporates Procedure 1 of Section 4.3.3(1) of the National Annex, improving result accuracy and preventing overestimation.
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.
