Re: [EnergyPlus_Support] infiltration

Thank you for the answer on that.

As far as the infiltration is concerned,

I am given a value of 133 m3/h and I guess that this value concerns the whole building.

How can I use this value for each thermal zone? Do I have to find out the volume of

each thermal zone and solve the n=q/v (ach) equation for each thermal zone?

thank you,

theo

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

Any suggestion?
Best Regards
