Problem with Boundry Conditions in EnrgyPlus simulation

grasshopper honeybee-legacy
1

Hey guys,

I am trying to run energy simulation for a whole building in energyplus and I am encountering sever errors when I run the simulation. The error I am getting is this:

  1. The simulation has not run correctly because of this severe error:
    ** Severe ** FenestrationSurface:Detailed=“ZONE_4_SRF_3_GLZ_0”, invalid blank Outside Boundary Condition Object

And there are tons of these errors for each zone.

I have attached grasshopper file. I tried to set every thing right. I do not know what might be the problem and how can I fix it. Could anybody tell me if I set my model right or wrong?

I would appreciate your help and response.

Hi Mitra:

Your GH script does not have the geometry. You need to internalize the geometry or attache the Rhino file. Thanks,

Dear Mohammed,

Thank you for letting me know. I have uploaded the rhino file here.

Hi Mitra,

I don’t know exactly what the problem is but your script looks complicated and it takes a long time to run. I tried to simplify it and it woks. Have a look to the attachment and let me know if you have a question. If you have a reason of doing your scrip the way you did and want to make it works, someone else might be apple to look to it and help you.

Thank you,

-Mohammed

Thank you so much for your help. That seems really good and it completely works as a start, I just have to introduce internal windows to that. My intention was to introduce internal windows between atriums and internal spaces so I divided the zones. Also for next steps I may need to define different conditions for different zones. Don’t know if I can make that to work. But the model that you sent me is a big help. Thanks again for your time.

Best,

Mitra
