Hi Bruce and all, 

I wrote a FREE windows program using Visual Basic that might help.  This 
allows you to make bin data for any of the 239 US cities where TMY2 data 
was collected and published by the US government. 

Download the self extracting zip file by entering this URL:

There is no link from my site to this program.  You must type the above 
URL to start the download.  So far, this is an exclusive offer to members of 
this list.  After I make a few more improvements, I will make it available to 
the public.  Some people took a copy of this program last month when I 
announced it on this list.  Those of you who gave me feedback...I 
appreciate your input.  

If you took a copy last month, you might want to upgrade to this version...it 
breaks down temperature bins by month and also includes the source 
code.  It also fixes a problem where reading the TMY2 data file from a 
network drive was VERY slow.  This program is written in Visual Basic 6.  
The VB6 source is included with the program in case you want to modify it 
to suit your needs.  I only ask that this software not be used in any 
commercial software sold for profit. 

This program converts TMY2 weather files to bin weather data for quick 
energy calulations.  The bin data is stored in .CSV files that can be opened 
directly by Excel or just about any other spreadsheet.  It considers the dry 
bulb temperature only. And currently, only US imperial units. Your can 
choose to create 2 degree, 4 degree, 5 degree, or 10 degree temperature 
bins.   

TMY2 weather data files are available for free on the Internet.  See the 
README.TXT file for details.
