Problem with adding Window EP Material to Library

Hello all,

I know that the question have been asked before, and I did follow chris's tutorial, but for some reason the new material does not appear in the library.

Is this the right connection for a window material?
is it related to being a no-mass window? because I only have the u-value and the SHGC.

thanks in advance.

Adding Window material from the library did not work too.

even though I selected the material from the list, I get the following error:

"1. Can't find FIXED WINDOW 3.81/0.49/0.38 in EP Construction Library.
Add the construction to the library and try again."

You need to update your components (sync with github). I'm pretty sure that this issue is already fixed. Did you try to search the group for this issue?

I did use the Honeybee_Update Honeybee,to update my components :

but I still get the same warning,only with the window material, both with new material and the material from library.

I don't know what am I missing.

I checked the following discussions,although informative, but not with similar issue:

Thank you for your time and patience.

Mostapha, hello. I may be running into this same issue at the moment: the setHBZoneConstr function isn't able to pull the window construction from the library. I tried sync'ing for the most up-to-date version of LB/HB, and doing the whole quit-restart rain dance, but no success yet. I suppose the work around for the moment is, don't change the window construction! not a huge deal, I can get at it in the idf. But if you have any suggestions, let me know.

Thanks!

Nick.

I haven''t answered my own question yet, but do have a little more information...

On running your "uninstall" script, the item selector refuses to budge:

Now to learn how that works and try to do it by hand...

Hi Nick!

Your case is quite different. It's because Clear 3MM is a "material" and not a "construction". In EnergyPlus you can only assign the constructions to surfaces. All you need to do is to create a construction using the material and then assign the construction to the zone. Here is an example:

I just wanted to give you an easy question to start the day with;)

Thanks!

You are missing the input for VT.

Thanks Mostapha !

I did add the VT, the component was successfully added to the Library.

I thought because I only had the u-value and the SHGC, the VT will be a default.

Now, I still get the same warning about not finding the material in the construction library.
I think I still need to update the components as you mentioned.

Hi,

I have more or less a similar problem. I am able to add the constructions to the library, but when i run the simulation the report says it says "Failed to find 'x' in library". My components are updated.

Thank you

Blanca

Hi Blanca,

Do you have them added to the custom library or are you creating them live inside the file. If you're creating them in the file make sure you're not running Honeybee_Honeybee again which will overwrite the memory library (It is a bug which I need to fix soon). Adding them to custom library will solve the issue for now.
