A new methodology for the description of local wind pressures on the building envelope of mono-sloped roof buildings by using time series analysis is described. A simple AR(1) model has been proven sufficiently accurate to simulate an unlimited series of instantaneous local pressures. The model parameters are provided for different zones of the building envelope as a function of the building geometry and the wind direction. The model is used for generation of 'equivalent wind tunnel pressure coefficients' from which any statistics, including extremes with specified risk may be provided for codification purposes.
