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.

Thanks in advance,
