Ladybug allows you to visualize and analyze weather data in Grasshopper. This includes diagrams like the sun path, wind rose, psychrometric chart, etc., as well as studies of geometry like radiation analysis, shadow studies, and view analysis.

Honeybee connects Grasshopper to validated simulation engines, including EnergyPlus/OpenStudio (for building energy, HVAC sizing, thermal comfort, etc.) and Radiance (for daylighting and glare simulation).

Dragonfly enables the creation of urban-scale EnergyPlus and Radiance models by capitalizing on an abstracted 2D representation of building geometry, where all rooms are assumed to be extrusions of floor plates. It also connects to the URBANopt energy simulation SDK.

Fairyfly connects Grasshopper to LBNL THERM, which is a widely used engine for modeling two-dimensional heat-transfer in building components such as windows, walls, foundations, etc.
