Ladybug_Solar Envelope | solar obstruction envelope |
Ladybug_Solar Envelope Basic | solar obstruction envelope |
Ladybug_Sky Dome | Tregenza or Reinhart Sky Dome |
Ladybug_Radiation Calla Dome | Sky Dome for evaluating radiation |
Ladybug_Design Day Sky Model | Sky Dome for HVAC sizing |
Ladybug_Shading Mask | Sky Dome obstructed by context |
Ladybug_Sunrise Sunset | sunrise and sunset times |
Ladybug_Radiation Rose | 2D direction of solar radiation |
