We are trying to evaluate the best way of meeting this requirement through Option 1 - Simulation according to the latest (May 2011) Addenda changes (min. 10 fc on Sept. 21 at 9 am and 3 pm under clear sky conditions).
We have the project modeled in Sketchup.
My initial thought was to export from Sketchup into Daysim, but I understand there will be a problem with the sensor file and we'll need to create a text file (?). We have Ecotect and can import the .3ds file from the Sketchup Model and then export into Daysim.
I've also learned that Radiance will do the same analysis as Daysim.
Thoughts? What are other design teams using to meet this credit? Thanks in advance.

Susan, you are right that you need a sensor point file when you export from SketchUp to Daysim and Notepad is a simple tool to achieve it. Even if you take your model into Ecotect, you would need to define sensors, one way another.

In Ecotect, once you set the analysis grid and run it through Radiance, the sensor file is automatically generated to be used in Daysim. You will not have to generate a separate sensor file using that method. What little i have played with exporting projects from Daysim to sketchup, i always had issues with the sensor file.
