What is the (Current) State of the OpenStudio Radiance Measure?

Searching for documentation

  • I went through the official user documentation which is really short, only these two documents: Radiance Tutorial and Radiance Reference Guide.

  • I pretty much went through all the Youtube videos I could find on NREL’s channel about Radiance (a list is here

  • I also looked at quite a few questions about daylight and openstudio on UnmetHours.

Yet I still have many questions and/or concerns about the Radiance Measure.

I know this isn't the original intent of UnmetHours, but I feel like a global post (like community wiki) would be helpful, so pardon me for asking multiple things in this thread.


What is the current state of the OpenStudio Radiance Measure and what can we expect going forwawrd?

  • I read in this question that there is zero truth reporting at the end of the perimeter zone since the boundary is opaque. How should we place the illuminance map regarding the exterior walls?
  • Can you place a non-rectangular illuminance map? In Sketchup Plugin it seems you can't. If not, how do you deal with non rectangular spaces?
  • Is there any measure that would add an illuminance map to all spaces or do you have to do it manually? (Seems like this would be very doable to create one using the SDK...)
  • Will Dview eventually support visualizing the illuminance map results, or are we stuck installing Results Viewer from OpenStudio 2.2.0 for that?
  • Radiance Measure calculates sDA, but does the Radiance Measure calculate the ASE metric? (required by LEED).
  • Given the fact that Sketchup Make is apparently turning into a web application with no plugins at the moment (and no communication from Trimble about when/if plugins will be available), is there any other way to place Radiance-aware components onto your geometry? (Having to create geometry in an old OpenStudio version with Sketchup 2017 would be a major problem, since upon updating your model to a newer OpenStudio version you wouldn't really be able to go backwards to your old OS Sketchup Plugin to do ulterior modifications...)
