Consider the following portion of an airloop:

When I checked the air pressures at AirLoopExhausNode comparing them with barometric pressures of outdoor air, I got the following result:

To me this is surprising, because at AirLoopExhaustNode I would have expected air pressures at least the amount of outdoor air pressure, because here air is leaving the airloop. If air pressure at AirLoopExhaustNode is less than outdoors, outdoor air must be penetrating the airloop at this node, which is in contradiction with volume flow rates, as also displayed in output (which in this case are constant).

Am I mistaken with this interpretation, or is there maybe an ENERGYPLUS BUG ? (I could send you the osm-file).
