Re: [EnergyPlus_Support] Converting ASHRAE IWEC to EPW

The weather utility program on the EnergyPlus web site should work perfectly fine in converting the CSV weather files on the ASHRAE DVD (!) to EPW.   In fact, that is how I routinely convert all my weather files in that format (*IW2.CSV) to *.EPW.  Since the weather converter program does not recognize the *.CSV format as a standard file format (although it's virtually identical to the TMY3 *.CSV format upon which it's based), you will need to create a *.def file.  I don't have time right now to search or recreate that *.def file, but I will send you the converted EPW via separate e-mail.

I have the ASHRAE CD containing the international IWEC weather data. An example of the file name is "SAU_DHAHRAN_404160_IW2.CSV" Is there any way to convert this information into an EPW file? I have tried to use the weather utility tool in Energy Plus, but I am not having any luck. Thanks...Andrew
