Running Daylight Simulation Using Only OpenStudio Measures

To perform a daylight simulation analysis in OpenStudio application, the workflow mentioned in the OpenStudio website requires modeling daylight elements in SketchUp. My understanding is that the Radiance measure will not run unless there is at least a daylight sensor and an illuminance map (some posts mentioned even a glare sensor is needed) for a particular thermal zone, is that accurate?

1- Is there any other workflow to model sensors and illuminance maps without needing to use SketchUp? Maybe through measures? I already checked the BCL and found that there is the "Add Daylight Sensor at the Center of Spaces with a Specified Space Type Assigned" measure but nothing for adding illuminance maps.

Any thoughts would be appreciated.

Thanks!

Not really an answer to the Original Post. But I have the same exact Question/Issue .

And I wonder if those two measures are supported in a gbXML workflow, rather than via Sketchup?

I don't use Sketchup and am setting up Geometry from imported gbXML.

I've run the Openstudio measures in this order

  1. Add Daylight Sensor at the Center of Spaces with a Specified Space Type Assigned ( I assign them to every space that is of Office-OpenOffice) and this measure seems to complete and adds sensors to all spaces of this type.)

  2. Radiance Daylighting Measure

Running the second Measure it fails with this error:

Comments

@Redline since this is a very similar question (why am I getting this error using the Radiance measure) and not an answer to the original question here, can you please create a new post instead? You can "edit" your answer, copy the text, and paste that into the body of the new post. You can also link to this post, letting others know that they are related.
