<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have two questions about exhaust. I am modeling a
building that has an attached garage and needs ventilation. Would it be
correct to calculate the fan power from G3.1.2.9 since there really is no air
being supplied to the garage and just an exhaust fan, to me this would seem to
over credit this system in the baseline system. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Also have a large kitchen hood that is going to be served by
an exhaust fan with a vfd so the exhaust is going to be VAV and there will be a
runaround coil that will be used to preheat the OA coming into the AHU. Is
there a good way to model this VAV exhaust system with heat recovery. <o:p></o:p></span></font></p>
