Difference in radiation with IESVE

Dear colleagues,

I’ve made a quick analysis of the solar radiation falling on the building facade, and I get disagreeing results between IESVE and Honeybee. This is the overview with the color:

and this is the overview per orientation:

radiation per orientation
rhino iesve
S 1033 920 -11%
E 822 740 -10%
N 327 350 7%
W 656 610 -7%

Therefore, I have two questions regarding these results:

  • how does one explain differences of 10% in the radiation falling on the facade?
  • which one provides the most trustworthy results, IESVE or Honeybee?

Thanks in advance for the input!
