[Bldg-sim] TMY3 Released with 1020 US Locations

[Randy Wilkinson]

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.
