We present in this paper an advanced formulation of zonal models for calculating room airtemperature and airflow distributions. It is based on a new way of sub-dividing the room usings the Octree method. It allows us to obtain a partitioning based on airflow patterns. The behaviour of the room is represented by the connection of SPARK calculation objects according to its partitioning. The SPARKs objects represent sub-zones of the room or interfaces between sub-zones. We developed an automatic generator of zonal models. This generator performs partitioning of a room and assembles the appropriate SPARK objects to construct a zonal model of a room. Then SPARK solves the resulting set of equations and the airflow and temperature distributions are obtained.
