[Equest-users] Savings from Demand Control ventilation in eQuest

[John Aulbach]

All:

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.

My results show a 15% savings in cooling, a 64% savings in heating, and a 78% savings in fan.

Reasonable? Or am I "mis-simulating ??"
