There is now a free, open source plugin for Grasshopper called Ladybug that “allows you to import and analyze EnergyPlus weather data (epw) in Grasshopper and draw diagrams like sun-path, wind-rose, radiation-rose,” can “run radiation analysis, shadow studies, and view analysis,” and then show the results inside Grasshopper, according to the announcement in early 2013. The tool was developed by a graduate student from the School of Design at the University of Pennsylvania.
