<div class=Section1>
<p class=MsoNormal>I have a proposed 100,000 square foot school in Chicago that
I’m modeling with eQuest, when I have no ‘Night Cycle Fan Control’
on the main VAV air-handling systems (NIGHT-CYCLE-CTRL = Stay Off), my annual
energy expense for the building is around $62,000. When I turn ‘Night
Cycle Fan Control’ on (NIGHT-CYCLE-CTRL = Cycle on Any), the annual value
goes up to $96,000 (mostly natural gas consumption, with some electric
consumption due to fan power). I’m convinced that during the Night
Cycle Fan Control that the VAV systems are bringing in Outside Air, which is
making the energy go way up. Which report will show me if I am guessing
right about the outside air? And, how can I change the ‘Night Cycle
Fan Control’ outside air availability to NOT include at night?? So
that at night, the OA dampers are shut and it’s just doing a re-circ/reheat
scenario…<o:p></o:p></p>
