Hello to all, I am currently trying to simulate a vertical green facade with substrate. I realize that the software developer does not recommend using the Material:GreenRoof for highly sloped surfaces, so not even as a wall. However, I have already read some articles that used the Material:GreenRoof for the simulation and then made advanced settings via the AdvancedSettings and EMS. Nevertheless, it is still not clear to me in detail why exactly the GreenRoof is not suitable for vertical application. I am aware that gravity acts differently, which in turn affects the water distribution in the substrate, and also that the angle from the leaf surface to the substrate surface is different. But what other reasons are there and in what calculations do they manifest themselves? (Radiation Balance, sensible/ latent heat flux, ...?) I could also ask: Why is there no material:GreenWall? What are the difficulties? Where would be the differences?

I would be glad to receive good hints and explanations!

Maria
