DESCRIPTION 

Ladybug allows users to import and analyse standard weather data in Grasshopper; draw diagrams like Sun-path, wind-rose, radiation-rose, etc; customise the diagrams in several ways; run radiation analysis, shadow studies, and view analysis. This exercise uses a time- and location-specific sun trajectory to count the number of hours building surfaces are exposed to direct sunlight.
