Your problem here is that your design day file (.ddy) has no design days. Open it up, you'll see:

  ! No Design Conditions found for this Location

You should have SizingPeriod:DesignDay objects in there: at least one, but reasonably at least 2, one for winter and one for summer, and likely more than that to cover the range of possible situations.

The underlying problem is that you're using meteonorm, and likely for a non-standard location. How to create a .ddy file has been covered on this question with a very similar problem than yours: How to generate a ddy file for E+.

Shortly: the weather converter executable from E+ installation creates the .ddy file based on ASHRAE Handbook of Fundamentals*. You don't have data. You can use the STAT file to create your design days manually or use a ddy file for a location that's close by.

(*It seems that in E v8.3.0 it's using ASHRAE HoF 2013)

Note that a SizingPeriod:DesignDay looks as follows:
