There are two ways to model DCV in TRACE:<br><ol><li>Using ventilation schedules that follow occupancy patterns.</li><li>Using the CO2-based DCV option on the "Systems" tab, "Advanced" button and setting CO2 sensors to "Room" on the Rooms tab.<br>
</li></ol>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?<br>
