EnergyPlus simulation problem

Hello,

I study thermal engineering at Faculty of Mechanican Engineering and Naval Architetcture at University of Zagreb and the theme of my master task is energy modeling. I don't have a lot of expierience in Grasshopper (Honeybee and Ladybug) and I hope that you can help me. If u open grasshopper file u can see thats it's a bit messy but thats only because I label every surface individually so i can change them in later stages of energy modeling. So my problem is that I cantrun energy simulation and I'm getting message "1. Solution exception:'ascii' codec can't encode character '\u10D' in position 403".

Do you know how to fix this or am I doing this model in Grasshopper completely wrong?

P.S. English is not my mother tongue so I apologize in advance for potentially bad english.
