I´m trying to get the surface temperature for one hour in a year comparing the vegetation material and a high SRI material.
The model has two planes as outdoor shading elements, and I use two options:
Option 1: Red is high SRI material and purple is outdoor shading element.
The shading elementos works perfectly (See blue area)
Option 2: Red is vegetation material and purple is shading element.
I Can´t see the effect of the shading over the vegetation.
What is the cause of this?
Have you seen this thread?
Good detective work,
@Erikbeeren and @charlie.brooker .
The more that I find out about this roof vegetation model, the more and more skeptical I become of it. Clearly, EnergyPlus is still modeling the detailed solar distribution for this case since the Surface Outside Face Incident Solar Radiation Rate per Area output still shows radiation falling onto the surfaces:
… and the solar radiation is clearly absorbed by the vegetation surfaces correctly:
… but the temperature of…
I would test to see if the sample file comfort under a tree works as intended and then adjust your detailed model.
In your model it doesn’t appear that the top surface of the ground has been split into smaller surfaces - I’ve replied to a couple of threads in the past about why that’s important, hopefully you can find them if that sounds useful
I thought this bug has solved with VegetationMat in the 1.4.0 version, but I see the problem is with E+.
So, I´m going to refocus the analysis in other way, I still want to use Grasshopper instead of Envi-met.
