Hi devang,
I’m also trying to achieve this simulation and I’m not getting anywhere. Have made any progress since you posted this thread?
I know I can get directNormRad, diffuseHorizRad and globalHorizRad values from the LB import epw file, but unfortunately, the HB generate custom sky component(as proposed by Mostapha) does not receive direct Horizontal irradiance values.
Any help would be much appreciated
