Direct Sun and Daylight Factor calcs Failing

Hi, my HB Direct Sun Hours and HB Daylight Factor components keep failing.
I have tried reverting to version 1.5.6 using the versioner tool and Sync component. I have reverted back to the latest again using the versioner tool and sync.
I have tried reinstalling Radiance.
I have tried removing all spaces from all names and folder paths.
I have tried turning off cloud synchronisation of my files while running (though I moved the file to a non-synced location too).
I’m using a downloaded EPW, but that shouldn’t affect Daylight Factor as it is not used as an input.

In HB Direct Sun Hours there is a critical failure: DirectIrradianceCalculation(…)
In HB Daylight Factor it is a different failure: PrepareDaylightFactorFolder (failing)

I have attached this WeTransfer link with the .gh file with everything internalised and 2x log files, for Daylight and Direct Sun. (As a new user I cannot upload files yet)

Any help appreciated :smiley:

This progress looks :frowning: because there were failed tasks

Hi @SebStripp,

It says you ran out of disk space since the Radiance octree of your model is huge. However, I believe this is because of the Shades in your model. Some are duplicates and I think this is messing with oconv, the Radiance program used to create the octree. I tried to add the Shades in the end as shown in the image below and it runs without issues.

Btw, you might want to mesh the floor surfaces as seen below. This will give you a uniform grid instead of some grid faces being triangles.

Final remark… If you find that the daylight factor results are odd you might want to increase the ambient resolution. You can see more about that here or here.

Thank you Mikkel. This is all very helpful!
I did find the shading strange as I had only been shown one way of doing it and it is unclear (as a beginner) what differences there are in plugging shading or window reveals in to the room vs the whole model.
