Hi all,
I was wondering how to find the value of solar vertical radiation on windows/walls in Energyplus or Openstudio. I cannot find it on the list of output variables in Energyplus and it seems that Openstudio-Radiance does not generate this value either.
Thanks, Maryam
I think you want Surface Outside Face Incident Solar Radiation Rate per Area.
I think that's it. Thanks.
I need exactly this out put too :((
There are a lot of variables that deal with heat transfer on windows/surfaces. Are you looking for something like this?
Output:Variable,*,Surface Outside Face Solar Radiation Heat Gain Rate,hourly; !- Zone Average [W]
Output:Variable,*,Surface Outside Face Solar Radiation Heat Gain Rate per Area,hourly; !- Zone Average [W/m2]
Thank you. Do you know where I can find the definition of each? I could not find that in Eplus documentation.
Here you go:
Thanks! The variable I need is Surface Outside Face Incident Solar Radiation Rate per Area; Now based on the definition this variable includes ground diffuse radiation. However, in my model I have not defined a ground. Would that matter?

Could you explain what you mean by "vertical" here?
I meant solar radiation on vertical surfaces.
I can't remember if you can get that output directly, but you could always calculate it using the direct and diffuse solar radiation on horizontal (this you can get), and the various solar-angles.
