<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am modeling the active chilled beams system using an induction
unit. I have created a separate treated outside air system (TOAS) from where
the fresh air would be supplied to <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>the induction unit. I have hard coded the fresh air
requirement for each zone at the outdoor air CFM field under outside air tab as
well as under design flow cfm field under air flow tab<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

consumed is huge which is nearly about 20% percent of the overall energy
consumption.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>So then I zeroed out the fan energy i.e kW/CFM for fans =0
and only the TOAS has the fan energy but the fan energy consumption decreased
very little.<o:p></o:p></span></font></p>
