I am attempting to follow these steps, but I can't seem to figure out how to use the DOE2 unilities. It looks like it is only DOS based and I am not familiar with DOS. Could you walk me through the steps to convert from .TM2 to .bin using the DOE2 utility?
Thanks,
Tim

Be aware that what NREL calls TMY2 weather data is true text based TMY2
weather data per their original definition. DOE2 (eQuest) uses a binary
version of the TMY2 weather files. The binary version is about 1/10th
the file size of the original text based TMY2 file. You need to use
another weather processor to convert the true TMY2 into a binary version
(xxxxxx.BIN) for use with eQuest. You can't just rename the file as it
sounds like you did.
step 1 - Get the TMY3 weather file for your location
step 2 - Use NREL's TMY3toTMY2 converter to convert it to TMY2
step 3 - Use DOE2 or EnergyPlus weather utilities to convert the text
based TMY2 weather file to a binary version for use with DOE2 (eQuest)
I think you skipped step 3.
