Exterior Climate and Building Ventilation

The article shows methods for wind influence on building ventilation systems analysis.Solution has been carried out through the experiment in wind tunnel as well as by CFDmodelling. Mean pressures and pressure variations have been measured on the model surfacewith respect of the ventilation intake and exhaust usual situating, with height of the roofparapets modification. The experimental results was presented by pressure coefficients-outputis possible convert to different boundary conditions. The wind effect was analysed in differentwind direction. The measurement and simulation is focused to the top part of the buildingfaade and to the roof.
