There are two ways to model DCV in TRACE:

1. Using ventilation schedules that follow occupancy patterns.
2. Using the CO2-based DCV option on the "Systems" tab, "Advanced" button
and setting CO2 sensors to "Room" on the Rooms tab.

I'm curious which method of modeling DCV you all have found to be more
accurate or preferable. It appears that neither method automatically takes
fan energy savings into account--as far as I know, this must be done
separately using a fan schedule. Using "Cycle with occupancy" doesn't quite
seem to be what we want to model DCV fan energy. Any ideas?
