Hi!
I have a question about the different skies in HB and LB for a radiation analysis. I have seen some posts from other people asking similar questions, but I just want to make sure I understand everything correctly.
As far as I understand, LB and HB are using different functions of Radiance to model the sky. I am trying to compare these 3 components:
a. GenCumulativeSkyMtx, used for the LB radiation analysis that uses the gendaymtx function of Radiance.
b. genCumSky, used for the HB radiation analysis that uses the genCumulativeSky function, and
c. genClimateBasedSky, used for for the HB radiation analysis that uses the gendaylit function (am I right??)
My questions about this are:
#1 Are gendaylit and gendaymtx calculating the same thing?
#2 Is there a way to use the GenCumulativeSkyMtx component of LB for a HB radiation analysis? It seems that the output of that sky component cannot be used as input for the radiation analysis of HB. I would like to use something similar to the climate based sky but that only calculates result for a specific hour and I need an annual calculation. I thought to run it in a loop for the whole year, but that takes a very long time.
#3 If I understand it correctly, genCumulativeSky is less accurate than gendaymtx, so why did you use one for LB and the other for HB? I see at a previous post that you plan to change that (https://www.grasshopper3d.com/group/ladybug/forum/topics/the-difference-between-gencumulativeskymtx-and-gencumsky). Is this still the case?
Thank you very much for the help!!
Best,
