Re: [EnergyPlus_Support] Changes to epw file



For an EPW I came up with the procedure below, (red for what you might do diffrently)
Also you might look into  http://weatheranalytics.com/  who can create a custom weather file for $75..

Custom EPW
  1. Download closest EPW file
  2. Run and export INMBY (replace this step with your weather data)
  3. Use weather file converter change EPW to CSV
  4. Open CSV in Notepad ++
  5. Remove header
  6. Save as text file
  7. Open in excel as comma delimited
  8. Cut wind column, and place into custom excel sheet for editing this file type
    1. (replace this step with your weather data)
  9. Change all hours of the year by month to INMBY extrapolated data that have monthly averages over cut in speed.
    1. (replace this step with your weather data)
  10. Export as CSV that says nameEPW.CSV
  11. Open EPW.CSV with notepad++
  12. Replace header with custom header
  13. Save as EPW.CSV
  14. Open in weather converter, convert to EPW
  15. Open new EPW file in weather file converter and generate stat file
  16. Save .STAT file, and .EPW file with same name, and place in same folder
  17. Open weather file in EP launch
  18. Open IDF design conditions file in IDF editor, replace data in Windspire.IDF with design conditions from Weather file converter GENERATED idf
    1. (replace this step with your weather data)
  19. Edit IDF in text editor, to reflect the location
  20. Run simulation.

Hello All,

I tried searching a thread of making changes in weather file. I basically want to make changes in epw file by converting it to excel and then once making changes converting it back to epw. I found this attachment but didnt find how to convert excel file back to epw format. Can anyone suggest a link or something.

thanks,

SACHIN SHARMA
