Are you confusing infiltration and
ventilation?
During hot days in some hours it is convenient
to increase ventilation (night cooling or free cooling) in order to reduce energy
demand.
In my opinion you need to use simultaneously
infiltration (constant?) and ventilation (modulated according internal and
external temperature?)

infiltration due to natural leakages
Hi,
I am a beginner on EnergyPlus and am trying to model a small house with an
infiltration rate due to natural leakages of 0.5 air changes per hour (ACH).
I have set up the following in the idf file:
ZoneInfiltration:
DesignFlowRate,
Air_Leakage, !- Name
ZONE ONE, !- Zone Name
Constant, !- Schedule Name
AirChanges/Hour, !- Design Flow Rate Calculation Method
, !- Design Flow Rate {m3/s}
, !- Flow per Zone Floor Area {m3/s-m2}
, !- Flow per Exterior Surface Area {m3/s-m2}
0.5, !- Air Changes per Hour
1, !- Constant Term Coefficient
, !- Temperature Term Coefficient
, !- Velocity Term Coefficient
; !- Velocity Squared Term Coefficient
Where the "Constant" schedule was obtained from the
"schedules" data set.
I have looked at the results of the simulation with the above in place (there
are no warnings), but it seems that the room remains too warm. I am aware that
0.5ACH is not much but I am suspicious that this is not being recognised. Have
I correctly set this up?
Thank you in advance
Marcel
