Ladybug

Ladybug performs detailed analysis of climate data to produce customized, interactive visualizations for environmentally-informed design.

What is Ladybug?


Ladybug imports standard EnergyPlus Weather files (.EPW) into Grasshopper. It provides a variety of 2D and 3D interactive climate graphics that support decision-making during the early stages of design. Ladybug also supports the evaluation of initial design options through solar radiation studies, view analyses, sunlight-hours modeling, and more. Integration with visual programming environments allows instantaneous feedback on design modifications and a high degree of customization.
