Christophe,
  I believe that NTYPE12 is only calculated for external windows (refer 
to the documentation on page 6-20 of the 06-Multizone Building manual. 
You may be able to use the BALANCE 1 output file, which will give you 
the total solar that comes from adjacent zones. I don't think that you 
can get the solar that comes through a particular adjacent window.
Kind regards,
 David
