Abstract

Computational Fluid Dynamics (CFD) models are a valuable method for accurate analyses of natural ventilation in buildings. In fact, CFD allows modeling the interaction between outdoor wind flow and indoor airflow in detail. When dealing with complex building geometries, however, high-resolution grids are often required, increasing the probability of grid-induced numerical errors. To support the grid-quality assessment of CFD simulations for real buildings, performance indicators such as the Grid Convergence Index (GCI) by Roache (1994, 1997) have been proposed. A detailed grid-quality assessment for a cross-ventilated realistic office building is discussed in this paper and represents the first step for further comprehensive analysis of cross-ventilation in office buildings.
