Energy simulation - no results


Hi everyone

I’m trying to do my first energy simulation but the energyplus component dosn’t give me results and I cannot spot the error

Here are files which I’m working on (749.5 KB)
Stanza a caso.3dm (61.9 KB)

I’ve done some more attempts

It’s interesting that if, intead of construct the zone by HBsurface, I use mass2zones, the open studio component gives me this error:

  1. You need a newer version of Honeybee to use this compoent.Use updateHoneybee component to update userObjects.
    If you have already updated userObjects drag Honeybee_Honeybee component into canvas and try again.

Again other attempt; I’ve tried to use ladybug update component and (in both mass2zone and with HBsurfaces) I obtain this new error:

  1. Current document units is in Meters
  2. Conversion to Meters will be applied = 1.000
  3. cannot create the working directory as: C:\ladybug\openstudioresults\7_JUL_12:00concept0\OpenStudio
    Please set a new working directory
  4. Runtime error (MissingMemberException): ‘int’ object has no attribute ‘replace’

line 4694, in main, “”
line 4972, in script

Nothing changes if I set another working directory

The strange thing is that with an example file downloaded by Hydra everything is working.

How to run light consumption analysis

Hi @kdm.nivek,

A few important points about your file you need to check:

1.In Energyplus it’s not acceptable 100% glazing ratio. For example, you can scale down the child surface to 0.9 then, plug into the _childSurfaces input.

2.To create a window construction with one or multiple panes including window air gap Use Honeybee_EnergyPlus Glass Material component instead of Honeybee_EnergyPlus Window Material.
So, You can’t combine Honeybee_EnergyPlus Window Material with another layer such as window air gap.

3.Edit simulation fileName_ and remove special characters like this ( : ) and white_space.

4.It’s better to Update Honeybee & Ladybug also update your GH file’s components to most recent version.



Hi @OmidmRashidi thanks a lot for your help !

Unfortunatly i still have some issues

1) I get this error:

Current document units is in Meters
Conversion to Meters will be applied = 1.000

The name that it says is there so I don’t know why it shows this error and all the window’s attributes are filled :thinking:

2) It doesn’t like this list (for holidays) even if ti ask for it (788.6 KB)


just removed the glazing and added a glazing ratio and it works. (793.9 KB)



After some time of smooth woork, the file decided to stop doing so. This is what i get:

I rechecked what you wrote previously, but i couldn’t solve the issue. It seems that it has some problem in retrieving the geometry, but i don’t understand why.

Any idead?
