What is Ladybug?

Ladybug is an open source environmental plugin for Grasshopper3D that helps architects and engineers create an environmentally-conscious architectural design.  Ladybug imports standard EnergyPlus Weather files (.EPW) into Grasshopper and provides a variety of 3D interactive graphics to support the decision-making process during the initial stages of design.

What is Honeybee?

Honeybee connects Grasshopper3D to EnergyPlus, Radiance, Daysim and OpenStudio for building energy and daylighting simulation.The Honeybee project intends to make many of the features of these simulation tools available in a parametric way.

Hi Ludvig,

Thank you for sharing. Ajith, Vamshi and I had a discussion about their development and potential integration of the development into current workflows.

There are couple of technical difficulties for running the studies with WUFI w/o using the interface (and of course there are solutions/workarounds for them). What they have currently is a prototype/concept and is not ready for integration.

They told me that they are planning to do more development for the coming IBPSA 2015. I also believe that it will be a great addition and I'm anxiously looking forward to see what will come out of their development.

Cheers, -Mostapha

I just came across an interesting report on the internets describing attempts to integrate WUFI with Grasshopper. It would be GREAT to also have moisture analysis in the same workflow! Have you guys heard of this or been in contact? It would be nice if this tool joined the family.

I am soo excited about all these different tools converging in grasshopper. It's as if you guys are straight from the future and you are doing a great job, keep it up!

Hi all,

If you are experiencing any issues with downloading gendaymtx, OpenStudio libraries and other Ladybug and Honeybee files, you can download all the files from this link as a .zip file and manually extract it to Ladybug folder: (https://app.box.com/s/bh9sbpgajdtmmystv3n4).

You can find ladybug default folder by checking the output of Ladybug_Ladybug component. It should be c:\ladybug or C:\Users\%USERNAME%\AppData\Roaming\Ladybug depending on your user permissions.

Hi Lefeuvre,

My best guess is Honeybee can't find Radiance folder on your system and so it doesn't copy the library to the memory.

Does honeybee_honeybee component turn orange when you let it fly? If that is  the case can you check the message baloon and let me know what does it say?

Also please open a discussion for your question so we can share files. Also it will be easier to refer to the discussion later for similar issues.

Cheers,

Mostapha

Hi Mostapha,

I managed to install Ladybug and Honeybee but I don't manage to run a daylight factor analysis. I'm using a grasshopper file which was working in the past. But not now on my computer. I've got an error message in the Honeybee_Run Daylight Simulation VER which is: 1. Solution exception:honeybee_materialLib. I have defined a default material.

Do you know how to solve this problem?

Thanks for your help

François.

Hi Dimitar, I just replied to a very similar question here. I can just say that I'm really sorry because of the delay. I'm also the most frustrated person not to see the Butterfly out yet, but unfortunately there is not that much that I can do about the delay right now. It is totally out of my hands... You can read more in the link!

Comment by Rutger D on November 1, 2014 at 5:28am

Thank you Mostapha, your newer userobject seems to work.

Comment by Dimitar Baldzhiev on October 31, 2014 at 5:36pm

Dear, Mostapha,
I am wondering what is the progress with project Butterfly. Not that I am in a hurry but it is almost an year since you last mentioned it.
Wish you all the best and thanks for the great work you are doing!

All, back to the issues with genCumulativeSky please see this discussion.

There has been changes to Radiance's gendaymtx.exe and I have updated the userObject for gencumulative sky to work with the newer version. I will add a longer discussion later today. Meanwhile here is the newer userobject that you can use: Ladybug_GenCumulativeSkyMtx.ghuser
