RE: [EnergyPlus_Support] infiltration-nat. ventilation

You can enter two type of surface, one for NV the other for Infiltration. Pay attention with the schedules, for NV you don"t have the same schedule, infiltration happens all the time, NV depends on building design.

Good luck!!

Hello again,

In the building that I am simulating I ve been given a value

for infiltration and one for nat vent for the whole building.

Is there any option to e+ to apply the total infiltration/ vent. portion automatically in the whole construction?

Or else how can I be sure which are the correct values for each zone?

thank you

I have the same problem:

sometimes the temperature is too low

************* ** Warning ** GetSpecificHeatGlycol: Temperature out of range (too low) for fluid specific heat
************* ** ~~~ ** This error occurred 58225 total times;
************* ** ~~~ ** during Warmup 0 times;
************* ** ~~~ ** during Sizing 0 times.
************* ** ~~~ ** Max=-9.894200E-003 {C} Min=-11.665963 {C}

and sometimes (actually, a lot of times...) it is too high

************* ** Warning ** GetSpecificHeatGlycol: Temperature out of range (too high) for fluid specific heat
************* ** ~~~ ** This error occurred 3949461 total times;
************* ** ~~~ ** during Warmup 0 times;
************* ** ~~~ ** during Sizing 0 times.
************* ** ~~~ ** Max=277.409112 {C} Min=125.000118 {C}

Any suggestion?
Best Regards
