Pressure Test

[Lisa Bramwell]

Dear All,

I am currently revising my grasp of CONTAM using the Tutorials provided on the site.  For the pressure test file, the outer airflow paths connected directly to the ambient zone, windows primarily and ledges, tested at the pressure drop set by the simulation parameters.  However, for my indoor airflow paths, airflow rate and pressure drop are both zero, despite using the multiplier function for the airflow paths. Could anyone say where I may have gone wrong?  The indoor airflow paths are defined using leakage area per unit length.

Hi Lisa!

Airflows between interior zones of the building should all be zero.
The building pressurization test sets all the interior pressures to that defined for the pressurization test.

You can read about this in the CONTAM User Guide:
- Working with Simulations -> Simulation Parameters -> Simulation – Run Control Properties
