Hello everybody, I currently have an error on a very simple model that I am modelling on OpenStudio 3.1.0, E+9.4. The model is a simple box with 2 windows per wall (it helps me get acquainted with OpenStudio). I do not know how else to upload the file, so you can follow this link here. After the simulation is done (with some warnings) I get the following:
```
Warn: Annual Overview section failed and was skipped because: Optional not initialized. Detail on error follows.

I have a few warnings I still have not figured how to solve, but I think they are not the reason why OpenStudio is not outputting the Annual Overview. I checked that all thermal zones are assigned (it's only one really), so that should not be a problem. Does anyone know what to do to solve this issue? Thank you very much in advance!
Luca.
