FenestrationSurface boundary conditions and construction Errors

edit

In the future, please add tags for the software you are using, in this case EnergyPlus. Did you confirm that the base surfaces hosting the fenestration surfaces also has a "Surface" boundary condition. That seems to be the issue for that set of sever errors.

As for the second error, I would go back and confirm that you don't have any opaque materials in the construction you are using for the sub-surfaces. Specifically what is between the two layers of glazing.

ok , got it for tags. For databases surfaces that not all who ' surface ' as a boundary condition , some surface have ' outdoors' ' or '' ground ' ' as a boundary condition and precise in these cases I have not put outside of boundary condition object.

for the second error , between the two glass layers there is a layer of air and I create this material with specific characteristics features namely the roughness , the thickness , density ...

Sorry for the answer to the second question, i just see exactly what you're talking David

Are you modeling with OpenStudio? If so a common cause of boundary condition errors is forgetting to assign one space in your model to a thermal zone. You end up with outside boundary object references that refer to surfaces in the unused space.

Whatever tool you are using check two things.

1. Does the base surface for this fenestration surface also have "Surface" boundary condition
2. Does the fenestration surface have an outside boundary object, and is that object also in the model.

The title is way too vague to be useful (I've modified it but it's not great, feel free to change). Also, the error messages that are in the post do not match the screenshot... I've changed it too
