Abstract: Knowledge based computer system has been developed for the evaluation of wind conditions around buildings at pedestrian level. This paper concentrates on two major components of the system, dealing with the utilization of meteorological records and recommendations of remedies to improve the wind environment. Weather station data are the basis for predicting wind speed exceedances at a built-up site. Statistical analyses are incorporated in aerodynamic models via computerized procedures for the evaluation of wind conditions against discomfort wind criteria. For unacceptable wind conditions, remedial measures are proposed by the computer system. The selection is based on the overall ranking of remedies by considering both aerodynamic efficiency and non-aerodynamic merits.
