why I don't have the option to use Radiance?

I am using OpenStudio 1.9.0. Why I can't assign radiance as my daylighting tool like previous versions? In the previous version in the Run tab, I was able to use Radiance as an option. Should I configure that in other place in this version?

From the 1.9.0 you can use Radiance but you have to add it as a measure.

Yes, sorry, the Radiance functionality has been moved into an OpenStudio Measure. For added confusion, this particular measure is not on the BCL, rather it's part of the OpenStudio Application itself. For a quick primer on how to use the measure, see this video.

Thanks, I found the measure. I have another question, I asked somewhere else, But I didnt received any answer. Do any have any recommendation how to model daylighting shelves using the openstudio? Should I draw them in sketchUp?

Depends on what exactly this "daylighting shelf" is. The Radiance measure will export horizontal, diffusely-reflecting surfaces by way of the OpenStudio "interior partition surface" object. Specular (mirror) surfaces are not supported by the Radiance translator at this time. Another option is to use the "Daylight Redirecting Device", (Lightlouver) option on a shading control. This will use the Lightlouver BSDF to model a light redirecting surface with much better accuracy (and efficacy) than simple lightshelf-type objects. The above-referenced video shows the distribution of this Lightlouver.
