LEED V4 Daylight Option 2 Illuminance calculations

Hello Guys!

I’m doing a Daylight simulation in order to get results for the LEED daylight credit (using option 2) In the further explanation section, under the Illuminance modeling methodology it is said that the Direct Hor. irradiance should be calculated as Global Hor. minus Diffuse Hor. Using HB generated climate-based sky I’m able to get the three values (Global, Diffuse and direct irradiances) If I do the calculation as requested by LEED I do not get the same result as exposed by the HB components
(Global 490.97 - Diffuse 94.0 = 396 wh/m^2, while HB is showing 724 for the Direct irradiance)

Any help would be much appreciated

Thank you
