you can model radiant cooling with no ventilation by using a fan coil or VAV
system with no heating or economizer installed and set the fan efficiency at 0
kW/CFM.<o:p></o:p></span></p>

color:#1F497D'>We design a lot of radiant systems with separate ventilation (based
on DOE-2 and Title 24, one would think this was a physically impossible concept)
and I usually end up modeling it as an induction system with 100% outside air
if I can get away with constant fan control, zones not too different from each
other, and no operable windows. Otherwise, I have to use one of those nasty old
VAV w/reheat systems and fudge the efficiencies. The arbitrary restrictions in
eQUEST can be rather maddening.<o:p></o:p></span></p>

wise ones,<o:p></o:p></span></p>

anyone ever modeled radiant floor cooling in eQUEST? I am trying to
determine how difficult it will be to model such a system. Any input
