tap. Make sure if you are using chilled water select "Chilled Water
Air Handling Units" under Equipment Type. Then select CAV single zone or
terminal reheat (dependant on your situation) in the Air System
Type. Under the "sizing data" tap you can select "user define",
then specify your supply air and
ventilation CFM's. </FONT></SPAN></DIV>

water you will need to construct a building to be simulated. Thus you will
need to create a chiller and boiler plant and specify all pump
requirements. Then implement these into your building.

<DIV><FONT size=2 face=Arial><SPAN class=527570416-16032010>Is there a way to
force HAP to supply a constant air flow through a "system" (this includes
specifying return air and outside air requirements) and calculate the
cost of providing the cooling and heating water to the "system" and "zone"
reheats? Any explanations would be helpful.</SPAN></FONT></DIV>
