Pressure simulation program
conference paper
A computer program has been developed to predict the wind pressure coefficients Cp on facades and roofs of block shaped buildings. The program is based on fits of measured data, including wind shielding by obstacles and terrain roughness. Main advantages of the program are: it needs no expertise of its users on wind pressures; the input is simple. It exists of building and obstacles coordinates and orientations; generating C, values for ventilation model calculations needs no separate action. By linking the pressure simulation program and the ventilation calculation program as well as their input, wider application of ventilation programs for non-experts becomes possible. The accuracy of the predicted wind pressures in the first version of the pressure simulation program are promising. Especially complex building shapes and surroundings have to be dealt with more carefully, as well as increasing wind velocities in small passages. Also detailed improvements are necessary, e.g. to account for sloped roofs and the positron of ventilation provisions above roof level. Therefore, generation and implementation of additional wind tunnel data is planned, to improve the present version.
