Hello @MohammedAlshayeb and @AbrahamYezioro,
Thank you again for your input. Great to know how to do it in Ladybug; in this case I think I cannot use that example as I need to model the material properties to evaluate the effect of reflected sun rays for which I need HB.
However, I think I can use the HB+ in the discussion you mention as soon as I have it installed!
