Multi-zone airflow

Building simulations are used to investigate building performance and design the building systems optimally. In particular, the air exchange between zonesand with the environment has a pivotal role inmodernventilation system design. Nevertheless, the model of the airflow becomes difficult for the modeler, motivated by the complexity of the grid that has to be modeled. IDEAS, a Modelica library, includes components for thermal multi-zone models of buildings as well as models for heating, ventilation, air conditioning and other elements that interact in the same model.
