HB EP Window Shade Generator error


Hello everyone!

I’m experiencing a fatal error when designing external shading using Honeybee EP Window Shade Generator component and running the energy simulation. The error message:

The simulation has not run correctly because of this severe error: **
** ** Severe ** Line: 1572 Index: 29 - “WindowProperty:ShadingControl” is not a valid Object Type.

I have played around with multiple inputs of the Shade Designer, I updated the file and HB components, checked for any possible errors and could not find the cause for this error.

Next, I opened the Hydra shared file called EnergyPlus_Window_Shade_Generator uploaded by @chris. I wanted to check only the blinds part of the building so I only connected 1 zone as shown below:

The simulation of Chris’s file results in the same error as in my script, therefore, I only uploaded my test version of the file from Hydra.

I’m wondering if others would experience the same problem or if it is an issue with my machine. Many thanks for your help! :slightly_smiling_face:

Running just fine on my end.


Thanks for checking @AbrahamYezioro.

I still don’t know why this error persists on my machine, and I’m not too technical to find a solution. Perhaps uninstalling the plug-ins could help?
If someone has got any advice on how to solve it, please give me a shout :pray:

Running Chris’s simulation with all zones connected as in the original file I also get a different error, which is this:


Indeed there are different errors.
For the former, as i replied, i didn’t get any issues and it runs fine on my side.
For the later (when you connect both zones) the complaint relates to a missing construction for a window.
Checking thoroughly i’ve found that even though HB assign construction defaults for all surfaces you produced a case that seems to be is not considered for those assignments: The top window in the lower zone.
I manually assigned some default construction (Exterior Window) and now it runs fine. Find attached.
@chris , FYI.

Hi @aguosha,

I am not if you have sholved this as it has been some time now. What is the Openstudio version you are using.
In my experience, this component works for versions up to 2.6, but after 2.7 there is a naming missmatch that creates the issue.

@chris please correct me if this is wrong or if this is already a known issue.

kind regards,
