<p class="MsoNormal">I realize I am asking for relative numbers, but I am unsure how much Demand Control Ventilation can actually save a building. I ran the DCV Up/Down scenario on a 150,000 sf office in Oregon, where the fans ran 24/7 (and the people weren't
there at night). BTW, this was a VAV/VFD system.<o:p></o:p></p>

<div>
<p class="MsoNormal">My results show a 15% savings in cooling, a 64% savings in heating, and a 78% savings in fan.<o:p></o:p></p>
