RE: [EnergyPlus_Support] infiltration

Hi Teo,

The infiltrations values on a building depend on orientation (wind direction). If you have a value of 133 m³/h, for me, the best solution it's to simulate the buliding only with this value of infiltration (design infiltration), after you are going to have the infiltration value per wall (N, S, E ,W) with this you can calculate an infiltration surface for the airflownetwork.

Let me know if you need help!

Oscar.

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

************* ** Warning ** GetSpecificHeatGlycol: Temperature out of range (too high) for fluid specific heat
************* ** ~~~ ** This error occurred 3949461 total times;

Any suggestion?
