Hey, i have following measured weather data that i would need in EnergyPlus (10min values):

  • Temperature Air
  • Rel.Hum
  • WindSpeed
  • WindDirection
  • IDiff_H
  • IGlob_H

Can i read 10min values in E+? What do I write for all other values (which are not available, like Horizontal infrared radiation etc.?). How can i convert this txt file to an epw file? Thanks for your help!

The duplicate question marked above has a lot of information, but in general there are plenty of tools (like universal translator) you could use to resample your data as needed. I've never tried it, but if you follow the timestamp format, I wouldn't know why you couldn't use 10 minute timesteps

An EPW file is just a csv file, so you can just format the data in excel as needed, being sure to leave 8 blank rows for the header. The missing fields are a little more difficult, though there are estimation tecniques you can use to calculate them from variables you have. Most rely on cloud cover though, which you don't have.
