SunTools, a new Plugin for SketchUp is available now.

Plug-in Features:

  • SunPATH: visualization (month and year)
  • SunPOS: Sun Position for a date and time
  • SunVIEW: Axonometric views from the Sun
  • SunPENETRATION: Analyze Sun Penetration/Access in any specific analysis point.

Several features are work in progress or yet to be implemented. I think this is a very promising visulisation tool that helps understand local climate conditions (and is also a similar way Ecotect presents this info)

The plug-in can be downloaded after registration from: http://tx.technion.ac.il/~arrguedi/SunTools/download.html
