Wind flow

The proposition of an assessment method of wind condition in urban structures is presented in the paper. In the second part of the paper two virtual residential districts with different urban organisation have been investigated. An assessment model used to examine wind conditions in selected urban organisation structures defines quantitative and qualitative features of the study area. Two elements of the urban environment, wind conditions and urban development, are evaluated.

This paper is concerned with a building situated in the west of Scotland which faces severe weatherconditions with high wind speeds and driving rain occurring frequently. This results in extensivedamage to the building fabric, and affects the internal climate which leads to a serious issue in buildingconstruction. In this study, a three-dimensional numerical model of airflow around the building isinvestigated. This investigation is part of ongoing research on wind-driven rain which has establishedthe importance of moisture stresses, wind flow and rain impacts on a commercial building.
