Pressure distributions around buildings are important factors affecting the air infiltration and ventilation of a building and consequently energy. Existing methods of determining pressure coefficients are costly both in terms of time and resources. This report aims to show the benefits of using a computational fluid dynamics (CFD) program in this field. Work was carried out to predict the pressure distribution around a sheltered building. The CFD program was used to investigate how pressure coeffieicnts vary with building separation and the degree of shelter offered by an upwind building.
