Dewbee

Dewbee is a Honeybee extension that enables Combined Heat and Moisture Transfer (HAMT) simulations in EnergyPlus. It exposes the necessary inputs for hygrothermal materials and moisture sources while remaining fully compatible with Honeybee workflows.

Compatibility

• Rhino 8
• Ladybug Tools 1.9+
• Multi-year result parsing currently works only on Windows

Installation

1. Install Ladybug Tools 1.9+ if you haven’t already:
   https://www.food4rhino.com/en/app/ladybug-tools

2. Download Dewbee:

   • Clone this repository or download the ZIP and extract it.
   • The folder containing the source must be named dewbee.

3. Make Grasshopper aware of the dewbee folder. You have two options:

   Option A — Place dewbee in a known search path:

   • C:\Program Files\Rhino 8\Plug-ins\IronPython\Lib
   • C:\Users\USERNAME\AppData\Roaming\McNeel\Rhinoceros\8.0\scripts
   • C:\Users\USERNAME\AppData\Roaming\McNeel\Rhinoceros\8.0\Plug-ins\IronPython (814d908a-e25c-493d-97e9-ee3861957f49)\settings\lib

   Option B — Add the parent directory of dewbee to Rhino’s Python search path:

   1. Open Rhino
   2. Run EditPythonScript
   3. Tools → Options → Add to Search Path
   4. Select the parent directory of dewbee (not the folder itself)

   Example:

   • dewbee folder: C:\Users\USERNAME\Documents\GitHub_repos\dewbee
   • Add this path: C:\Users\USERNAME\Documents\GitHub_repos

4. Open samples/template.gh in Grasshopper.
   Dewbee components are shown with blue group blobs. Use them directly or convert them into user objects if desired.
