Hygrothermische Gebäudesimulation mit Multizonen-Gebäudedurchströmungsmodell

Hygrothermal building simulation coupled with multizone air flow model.

With hygrothermal whole building software it is possible to calculate heat and moisture transport within a building and its components. The natural or mechanical driven air exchange between indoor and outdoor climate as well as airflow between defined building zones are significant contributors to an energetically and comfortable indoor environment. At the design of the building model it is possible to set the ventilation per time step. However, the ventilation depends on the indoor climate. The hygrothermal whole building software coupled with a multizone building airflow model can simulate the indoor climate and the natural and interzonal air exchange influencing each other. This paper gives an insight into the airflow model and its implementation and shows some results of an example simulation.
