<DIV><SPAN class=203333019-09022009><FONT face=Arial size=2>I am still running
trnsys 15 but have received some model files from trnsys 16. Basically it is a
building simulation using TWY weather files. I can run the building in TRNSYS
fine, but need to use the radiation processor as the TRNSYS 15 does not has a
type 109 (but 89 for the data reader and 16 for rad.
processing).</FONT></SPAN></DIV>

<DIV><SPAN class=203333019-09022009><FONT face=Arial size=2>I notice however
that there are quite some differences between the different type 16's, depending
on the input you select. For instance, 16C uses total horizontal radiation,
temperature and humidity (no radiation smooting) while type 16i uses totla
horizontal and horizontal diffuse. Both methods can be used, as data is
available.</FONT></SPAN></DIV>

<DIV><SPAN class=203333019-09022009><FONT face=Arial size=2>Using 16C results in
slightly lower heating values, but much larger cooling values (2x higher), so
the effect is quite large. I have not been able to find out exactly which
procedure is used by type 109 though, so any information on that would be most
welcome. If more procedures are possible, is there a preferred
one?</FONT></SPAN></DIV>
