Therm in grasshopper

HI,

I have THERM 7.7, and I try to work it with grasshopper but I do not see THERM module inside Ladybug for the last version of RHINO and Ladybug.

How can I get it?

Thanks

Hi
Current Ladybug tools doesn’t support Therm. Although you can try Honeybee legacy that works with Them 7.6.
I hope that helps.

thanks for your answer

what do you mean with “try Honeybee legacy”?

do I have to download THERM 7.6 but still using the newest version of honeybee?

How can I see the THERM tab inside honeybee?

Ladybug tools and legacy versions are separated. You can find them in food4rihno below The Ladybug tools download options look for name"Honeybee legacy".

Hi everyone. I am an architect with no environmental background (so be gentle). I have been trying to work with THEM for the past weeks and really struggling. My project is about creating rammed earth walls- those walls thickness and surface geometry will be parametric- depending on the radiation value. in this way I can control the heat transfer and thermal mass. This is the dream! now reality, I have a few questions:

  1. In the subscribed tutorials and in the example files there is a different method to find U-value and R-value. from “Honeybee read term result” component - to find the U-Factor should I use the “Intwall total length” or “Intwall Projected Y”?

  2. How can I attach the thickness of the wall to its capacity to “store” heat for 12 hours during the day and the release at night? (I will attach my files)
    I appreciate any help.

Hello Hamy,
I was looking for an answer for the same issue that I have, and I found your answer. I have Rhino 8 on my computer. As I tried to download ladybug legacy, I noticed that it is supported by previous versions of grasshopper. I want to know how I can use THERM in grasshopper with Rhino8.
Thank you so much.

@Jasmine.Nrz THERM tools only work in R6, not 7 or 8 you can get a legacy license for free on the McNeil website if you have a current license and get R6 that way, I keep a r6 install on my machine for this very reason

Thank you so much Trevo for your reply.
I downloaded Rhino 6 now. If I download ladybug legacy plugins for Ladybug and HB, I can open work with THERM inside the grasshopper?
And does it effect my latest Ladybug and HB plugin in Rhino 8? or I can have different versions of this plugin on my different Rhinos?
Thank you.

The Ladybug legacy version and the new Ladybug Tools are two independent versions that do not affect each other

Hi Jasmine,
Some of the ladybug group`s projects are not currently updated such as legacy versions. Therefore, their software dependencies have not changed since the last update. As result, you need to install rhino 6 for your project and don’t forget to install therm 7.6. I remember that they have a matrix of dependencies for their products on GitHub.this may help you find appropriate versions of each plug-in.

Can you make calculations 3d?

Hi @albertomorales - THERM is a 2D Heat-flow solver, not 3D.


Also, not to derail your thread on THERM, but if you are interested in 3D TB’s, I would recommend checking out the Beyond-Carbon + SimScale workflow

I have not tried it out yet myself, but looks like it could be promising?


FWIW: The tool we use in our office for 3D thermal bridges is Dartwin which can accept .OBJ files created in Rhino without too much fuss.

Thank you so much, everyone, for your replies.

I’ve downloaded Rhino 6 along with the compatible versions of Ladybug and Honeybee. For a project, I created a wall section to calculate its thermal conductivity and I could get the U-value for that wall.
Now, I have another question: I plan to modify the single wall section into multiple generated wall sections with the same outer thickness but varying internal parameters. My goal is to calculate the thermal conductivity for each variation and add the results to my dataset. Do you have any advice on how best to approach this?

Thank you so much for your help!

Hello Edpmay,
Thank you for the information you shared. I just checked Dartwin website, and noticed that it is not a free software. right?

Hi @Jasmine.Nrz , yes you are correct - Dartwin is not free software.
