I’m trying to model a VAV-system for an office building, but I keep on getting outdoor air volume flow rates in the morning that are too low. I’ve set the flow per person to 0.007 m3/s (7 L/s) in my program, but between the 7am-8am, when the first occupants arrive the volume flow rate is below 0.007 m3/s per person. As seen on graph below:
When the simulations are done for the full floor, then it’s for even longer periods below 0.007 m3/s per person:

Is it overruled by some thermal requirements? Or what could be the reason?
@MingboPeng maybe you can help?
