Hello people, I was using OpenStudio 1.10.0 and when I added the Radiance Daylighting Measure and ran the simulation, it got failed immediately after a few seconds. When I check the Tree tab there is no .err file to see the errors! According to this post I upgraded it to 1.10.4 and added another daylighting measure and got the same result. Now I'm using 1.10.5 and it still doesn't work! Any help please? image description

ERROR: FenestrationSurface:Detailed="SUB SURFACE 248" has an opaque surface construction; it should have a window construction.

Did you check the construction assigned your window surfaces? The error message is indicating they are not correct in your model. A window construction should be built up with 'Glazing Window Materials'.

As the multitude of error messages state, your window (subsurface) constructions are opaque; the Radiance measure does not like that. Using either 'Glazing Window Materials' as Eric stated in his comment, or (preferrably (to me)) 'Simple Glazing System' materials, will work out better for you.

@rpg777 It's already Theoretical Glass. The thing is that everything is ok before adding the Radiance Daylighting measure and the simulation runs perfectly. But right after adding the measure it gets failed.

It's entirely possible that the Radiance measure is not dealing with the theoretical glass type correctly. Thanks for pointing this out, we'll take a look! In the meantime, we suggest you try using the more typical glazing materials mentioned above.
