Ladybug Primer

This primer provides an overview of the Ladybug components for Grasshopper.

Ladybug imports standard EnergyPlus Weather (.EPW) files into Grasshopper and provides a variety of 2D and 3D graphics to support the decision-making process during the early stages of design. The tool also provides several simple geometry analyses, including incident radiation and direct sun hours.


See the Wiki of the lbt-grasshopper repository for the installation instructions for the entire Ladybug Tools Grasshopper plugin (including ladybug-grasshopper).


Post your questions to Ladybug Tools forum and see the ladybug-grasshopper repository for source code.
