Hello! I am in the process of building a veranda that will have windows all around, with a 45x120 joist between each window, and the windows will be 71 cm from the floor.
So essentially, the facade is 71 cm high, and the facade will probably go down an additional 25 cm, so let's say the facade will be 95 cm high under the windows. How do you make it ventilated?? I plan to lay the panel horizontally so it will be vertical battens. Where should the airflow be led out? It can hardly be led up between the windows. Should there be a slit under the window sill for the airflow??
This is something I've missed... How do you do it? HELP!

You don't really do anything, the air gap is actually quite "tight" and there are no air currents behind it. The air gap provides a space so that any penetrating water doesn't remain for too long and cause rot, but it doesn't need to be a "hairdryer" behind it, it dissipates quite quickly anyway.
Yes, a bit of the chimney effect will probably occur on a facade that is a bit higher. And if the sun is shining, the air will likely move quickly.
But you mean that "ordinary" leakage is enough to remove any air. If you have a vertical facade, you either have a milling on the back of the panel so the battens don't seal completely, or you have not battens, and the panel is mounted with gaps to get the air moving. Then it's open both at the bottom and the top. But here it will be completely sealed at the top unless I open up slots.
But I don't think I've ever built with horizontal paneling. I've only demolished such where there was completely no air gap between the panel and insulation, and that wall was from 1962, and in 2010 when I demolished it, the wood was like new. Although wood was treated a bit differently before, nothing could grow on such a board.
