modifying TMY2 weather file in BIN format

Hello all,

I need to modify the direct normal and total horizontal solar values in the
BIN format TMY2 weather file used by DOE-2/eQUEST to ensure both DAYSIM and
DOE-2 provide the same exterior horizontal illuminance. Any pointers on how
this can be done or an alternative approach will be appreciated.

Regards,
Ramana.

Venkata,

As DAYSIM weather files are based on Energy Plus weather files, you could just convert Energy Plus files directly into DOE-2/eQuest bin files using the eQ_WthProc executable from the DOE-2 web site:

Hope this helps,
