Revision history [back]

I usually rely on ideal loads when modeling during the earliest stages of any design for evaluating architectural configurations and envelope considerations. I recently discovered that providing a schedule in the OS:DesignSpecifcation:OutdoorAir object does not apparently impact the energy associated with ventilation for a project. This is admittedly only a quick test, but I could not verify any changes at all in the ABUPS report when swapping out schedules.

Is there another controlling factor such as population or an "Hours of Operation" schedule that controls this say during unoccupied periods? For example, Trane Trace 700 controls system operation around a threshold of 5% population.

I see that the "Minimum Outdoor Air During Occupied Hours" reads 0.011 ACH for Simple Venitlation and the "Average Outdoor Air During Occupied Hours" reads 0.695 ACH for Simple Ventilation. Clearly something is controlling the OA rate. I just do not know what that variable is.

Lastly, where can I look to see the actual simple ventilation during a given timestep? Or, should I just give up on ideal loads if I am looking for this amount of feedback from the model?

Thanks for any help.
