su2ds allows users to create geometry in Sketchup, export it to Daysim for analysis, and import the results of this analysis back to Sketchup for display.

Installation files and a manual can be found on the Downloads page.

su2ds was created by Josh Kjenner for Manasc Isaac Architects, and is supported in part by the National Research Council's IRAP. It is based on Thomas Bleicher's Radiance exporter plug-in for Sketchup, su2rad.
