[EnergyPlus_Support] Zone Infiltration: no heat gain; only loss

["JV Dirkes II" <jvd2pe@xxxxxxx>]

Dear E+ Support Group,

I am using the following two Report Variable statements:
Report Variable, *, Zone Infiltration Sensible Heat Loss, hourly;
Report Variable, *, Zone Infiltration Sensible Heat Gain, hourly;

As I review my .csv output, I see that the Zone Infiltration Heat LOSS
is almost always greater than zero (occasionally it's zero).  The Zone
Infiltration Heat GAIN is NEVER greater than zero....even when the
windspeed is greater than zero AND the outdoor temperature is above
the heating setpoint.

This seems wrong, because if infiltration is occurring, and the
infiltrating air is warmer than the setpoint, there should be a heat GAIN.

I should note that at the times I expect an infiltration heat gain,
the zone temperature is much higher than the setpoint.  Also, my model
is not concerned with cooling, so I've got the cooling system OFF at
all times.

Why is the Infiltration Heat Gain zero when wind is present and the
outdoor temperature is warmer than the setpoint?  Thanks!
