Grasshopper

algorithmic modeling for Rhino

Hi,

I'm performing thermal comfort analysis for some project...

I've recently installed the OpenStudio, but it doesn't work (till now i used the EnergyPlus)!

The HB_exportToOpenStudio component complains about:

  • Solution exception:invalid literal for float(): 

I have:

Rhino - Version 5 SR5

OpenStudio 1.13.0 

EnergyPlusV8-5-0

SketchUp 2016

Any suggestions??

regards,

Saba

Saba,

I figured out what is happening.  There is a slight difference between your epw file and Abraham's file.  Specifically, it seems that your epw might have been opened in excel (or another tabular software) and re-saved as a csv, thereby adding a few extra commas onto the end of one line:

I have fixed the OpenStudio component such that it can now handle this type of EPW and you can find attached a GH file that manages to write the IDF and OpenStudio model.  However, because of some other things wrong with your EPW file, EnergyPlus throws an error about it when it tires to run the simulation.  I'm sorry that I can't completely solve your problem but at least you get the right error now and you know that something needs to be corrected in your epw now.

Thanks Chris,

Veryyy weird. The EPW files are supposed to be the same.

Anyway, Saba: Please download the EPW from one of the above dialogs and try it. It runs fine on my machine.

Hi,

Yesss.. It runs fine now:) 

Thanks a lot..

Saba

Finally,

Seems to be that the epw was indeed corrupted.

Thanks Chris for the fixing.
