<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>My
question is in regards to setting up the design case model to reflect demand
control ventilation. So far, I’ve set the min OA schedules for the
zones to 0 during unoccupied hours to limit OA and set the HVAC system min OA
method to DCV return, and this has shown some savings. The occupied hours
for some of the spaces are roughly 12 hrs/day, but the spaces will be occupied
roughly 1/3 of the time during those hours. As this project is going for
LEED, is it acceptable to adjust the occupancy schedules in any way to account
for the effectiveness of the DCV system when these spaces are
“unoccupied” during occupied hours, or does anyone have any
suggestions for other changes I can make to the design case model? This
is really an ideal scenario for DCV as the occupied schedule for the building
is long (at least 12 hrs per day), but the actual occupancy of the building
will be sporadic and I’m concerned that the model isn’t reflecting
the full-effectiveness of the DCV system.<o:p></o:p></span></font></p>
