ok, now that I am looking at the epw file in notepad, i see all the illuminance levels. must be something wrong with the way my dview visualizes the contents of the epw file, because i surely do not see the illumination values of ankara in dview?!

The EPW format is just a comma-separated text file.
I use vi, an old unix text editor, but any text editor would work (notepad, word, etc.)

hi joe,
if i am not mistaken, these values are empty for ankara. i am using dview to see the data, and illuminance is not there. what do you use to view the data?Â

I would be happy to provide an IWEC2 weather file for Ankara (for a price), but I think the IWEC weather file on the EnergyPlus Weather web site does contain solar illuminances, which are listed immediately following the solar irradiance on each line.

hi,

i am looking for the HOURLY direct and diffuse solar illumination values (in lux) for ankara, turkey. in the epw file, no such data exists. do you know where i can find it, or how i can calculate it based on the solar irradiance values?

thanks!
