The package Buildings.Airflow.Multizone contains models for 
multizone airflow and contaminant transport.

The models can be used to compute the air flow between different rooms and between a room and the exterior environment. In multizone airflow models, typically each room volume is assumed to be completely mixed. The driving force for the air flow are pressure differences that can be induced, e.g., by

Wind pressure coefficients for different building configurations can be found in Costola et al. (2009).

The models in this package are as described in Wetter (2005), except for some changes that have been done when migrating them to Modelica 3.1, which led to a simpler implementation based on the stream functions.
