Hi everyone,
In my actual weather data, I don't have Horizontal Infrared Radiation Intensity but cloudiness, whose unit is octa (i.e. 1 is 1/8). From Energyplus documentation, I saw that the Horizontal Infrared Radiation Intensity can be calculated from the Opaque Sky Cover, whose unit is tenths (i.e. 1 is 1/10 covered, 10 is total coverage). Could someone tell me please if the cloudiness in actual weather data corresponds to the Opaque Skey Cover in EPW. If yes, Do I have to convert octa into tenth for the calculation of Horizontal Infrared Radiation Intensity?
Thank you very much for your help.
