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.

You can get started by watching this video:

Here are three separate playlist for Ladybug, Comfort tools, and Honeybee.

Is is possible to color other types of people with the ladybug comfort mannequin component. for instance if i don't want to use the 3d mannequin but color a 2d architectural person or even another 3d figure i downloaded , perhaps a more realistic looking mannequin? thanks. amazing tool.looking forward to learning it better. e

Hi Joyce. Yes. Ladybug and Honeybee is free for educational or commercial use. There are couple of differences between the current release and the first release but the workflow is the same. Please add a discussion if you have any other questions.

Hi Mihail, Thank you for the kind comments. The short answer is yes. I saw that you started a discussion. I will reply with more details there.

Dear Ladybug + Honeybee

Why does "readme" this tag be shown in these two component not "report" after installation of Ladybug + Honeybee?

Thanks a lot

The problem was just on the GHPython file, it was blocked :D

Comment by Mostapha Sadeghipour Roudsari on March 12, 2015 at 8:19pm

Hi MohammadMahdi, This error happens when you don't have GHPython installed correctly. Are you sure that GHPython is installed correctly on your system? This discussion may also help!

Hi Paul, There has been discussions about Ladybug for Dynamo. It will start at some point. I can't give you an exact day right now but we have been thinking about it. We need to make sure that if there will be a Ladybug for Dynamo it will be as good as the one for Grasshopper. It's also important to make sure that sure that we will be ready to support two developments (if not 3 considering the web-based version which will be out at some point next year) at the same time!
