Wrokflow logic: Eddy 3D + Ladybug for outdoor UTCI

Greetings,

I was wondering if anyone before has used Eddy 3D as an input to simulate outdoor thermal comfort? I am working on a GH setup that should optimize courtyard dimensions to accelerate wind and increase shading to improve thermal comfort for outdoor and indoor. I am using:

  • LB incident radiation (geometry: courtyard walls and floor, context: the whole house) to surface temperatures.
    -LB human to Sky relation (with LB generate point grid connected to courtyard walls and floor)
  • and Eddy 3D where I am using the wind factor annual as an input to UTCI wind velocity.

Does this count as a valid approx for calculating the impact of courtyard dimensions on UTCI? would greatly appropriate your help.

Hey,
You can use UTCI comfort map component to calculate the solar radiation and input the air speeds via submitting a csv file. You can find examples of the wind inputs on this forum.
Cheers

Thanks Dimtry, I know we can do that via using an excel sheet or a direct input from epw file. But here in this case, I am testing different courtyard dimensions impact on wind velocity/ air speed through Eddy 3D, would that be a valid approach?
