What is Ladybug?

Ladybug is a free and open source computer program that supports environmental design. Specifically, it is a Grasshopper plug-in that helps designers make informed decisions about the environmental performance of their buildings. It visualizes weather data, solar radiation, and other environmental factors within the Grasshopper environment, enabling users to analyze building performance early in the design process. It is commonly used for tasks like shadow studies, solar analysis, daylighting simulations, and energy performance assessments.
