I would look at the conditions of the air that you are supplying
to the building; my guess is that the air going in is VERY dry and
probably quite cold as well. The RH in the room would drop because
of the dry air being added to the zone (and the quantity of mixed
air being drawn out of the zone and returned to the cooling coil.<br>

yes, it does. If you look in the *.inf file, you'll see the
following lines:<br>
<br>
GAIN PERS_ISO02<br>
CONVECTIVE=156 : RADIATIVE=78 : HUMIDITY=0.081<br>
<br>
there is 0.081 kg/h of water added to the airnode per person (and
according to your schedule)<br>

2) Does the humidity model actually affects the amount of

yes. There are two humidity models. The simpler of the two is the
effective moisture capacitance model. Type56 computes the quantity
of moisture that the air can absorb (based on its current conditions
of temperature, pressure, and humidity ratio), then multiplies that
quantity by the user-specified multiplier to determine the zone's
actual ability to absorb moisture.<br>

I am not sure I understand your question; humidity gains go into the
zone's air node. <br>

Type56 assumes that the air in the building is at 1atm; there is no
way to change that assumption as far as I am aware.<br>
