An evaluation exercise of a wind pressure distribution model.

States that one of the most important parameters for multizone airflow simulation is the wind pressure distribution around a building. Pressure coefficients usually form the input, and the values derives from wind tunnel studies. Alternatives to wind tunnel tests are suggested, namely the use of statistical regression analysis of data obtained from wind tunnel studies. Describes how pressure coefficient values for a shop building were generated using a new wind pressure distribution model based on the regression analysis as well as on wall averaged values from published data. The values generated are analysed and discussed. Also considers the effects of such accuracy on the computed air flow rates and age of air for the building using a multizone network airflow model.
