<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>I’m
having the typical issues with getting an enthalpy wheel to show appreciable
savings. I’ve adjusted some of the control sequences, and have
managed to show a savings in cooling energy, but I’m getting no heating
savings, which is strange, unless my building is actually asking for cold OA
during the winter because of the rather large internal heat loads (my guess is
that this is true).<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>My
question is whether you HAVE to define zonal exhaust airflow rates to properly
show the savings from heat recovery, or if the program knows that the exhaust
will roughly match the OA delivered to the space? Do I have to turn on
exhaust tracking?<o:p></o:p></span></font></p>
