Hi @Mathiassn
Yes thank you - how about you?
Building on what we learned at the Radiance Workshop I would say that the primary factors for the disagreement in the fidelity study (comparing an hour of the annual 5PM study {rcontrib} with the point in time study {rtrace}) is:
-Discretization error from using klems resolution BSDF. With the discrete BSDF, the effect of having a 145x145 patches sky (annual study) vs a continous sky (point in time) will be magnified compared to if you had a continous formulation of the angular dependencies of the IGU/IGU with shading - this could be “glass” material or a higher resolution BSDF that better resembles the continuous dependencies.
-5PM in honeybee+ uses a different and more accurate solar algorithm to calculate the suns position compared to point in time from Radiance.

I ran the simulations over night or during weekend on multiple computers using Radiance. Havn’t been using Accelerad or docker - have you?
