Hi,

We are working on an apartment complex. In most of the cases the supply of fresh air is via the living space and the exhaust is placed inside the toilet. So, the air enters the living room and it overflows to the toilet where it is taken out.

Please let me know how do you simulate overflow of air from one zone to another zone in the E+ or Design builder.

This overflow of air -- supply air provided to one zone, mixes with an adjacent zone, then eventually exhausted or returned back to central air system from the adjacent zone -- is also known as transfer air. This post has a good discussion on how to apply this in EnergyPlus using the ZoneMixing object (defines the one-way mixing of air between two zones).

DesignBuilder allows you to define air mixing between zones within an Interzone Airflow dialog. Here you can define the mixing process (zones involved, the flow rate, controls for temperature or time-based schedule limits).
