Abstract: Usually, in dynamic building energy simulation software the spatial distribution of air temperature within a zone, useful for the analysis of local comfort conditions, is not available. Co-simulation with CFD codes can overcome this problem but computational costs increase exponentially. In this paper, a new simplified zonal model, able to model in a simple way the air convective flows due to buoyancy forces, is proposed and implemented in the dynamic simulation software ALMABuild. The reduced CPU time required by the model to simulate the mass and energy exchanges among nodes allows an accurate analysis of multi-zone buildings avoiding heavy co-simulations.
