style='font-size:10.0pt;font-family:Arial;color:navy'>Thank you, but i already
thought about that and i have nothing specified there. But now I tried to
specify the flow to each zone instead of doing it for the whole system and then
the outdoor air ratio is calculated correctly. Of course I considered the
induction ratio so I specified for each zone 1962 cfm supply flow (induction
ratio of 2) then I get an outdoor air ratio of 1 and 918 cfm OA per zone. Do
you think I can do that? It is strange so as the other way should work as well.

style='font-size:10.0pt;font-family:Arial;color:navy'>I have an induction unit
for the whole building, supplying 204000 cfm outside air to the building. So I
specify the supply flow of the system (204000 cfm) and set the min outside air
ratio =1. In the SV-A report it shows on the system level 0 outside air and
therefore no cooling/heating capacity and for the zone it shows about 800-1100
cfm outside air. Only if I do not specify the supply flow on the system level
then I also get an outside air ratio of 1 for the system level. Why is it not
possible to tell equest that the 204000 cfm it supplies is only outside air. I
have not specified an economizer so it should be outside air all the time ??<o:p></o:p></span></font></p>
