Air Exchange Rate

[Lisa Bramwell]

Dear Stewart,

I have determined the air exchange rate for two buildings I've modelled using CONTAM.  How do I check within CONTAM that the air exchange rates are comparable if not the same for the two scenarios?  In the first, I've used a simple AHS and in the second natural ventilation using air flow pathways only.

Sincerely,

LB

You can view the <project file name>.ach files to see the air change rates.

Please note that one can access the help/User Guide via the Help menu.

The documentation can be searched for “air change rate” to fine related information.

In the Airflow Simulation Results panel, you can request a "Building Air Change Rate" report.  This produces an "ACH" output file.
