Wind pressure coefficients for roof ventilation purposes
Wind pressure coefficients (cp) are important inputs for analytical calculations of wind load. The aim of this research is to investigate wind pressure coefficients on a test house located in Norway in order to pave the way for improved analysis of wind-driven roofing ventilation. The large-scale test measurements show that the wind pressure coefficient along the eaves of the house varies with different wind approach angles. Assuming wind-driven air flow through the air cavity beneath the roofing, an average value of 0.7 is derived for practical engineering purposes. The results from the study are applicable for single or two-storey houses with pitched roofs at different roof angles ; Acknowledgements The authors gratefully acknowledge the financial support of the Research Council of Norway and several partners through the Centre of Research‐based Innovation "Klima 2050" (www.klima2050.no). A special thanks to CAD operator Bjørnar Nørstebø and Remy Eik. The authors also gratefully acknowledge the anonymous Journal of Wind Engineering & Industrial Aerodynamics referees for valuable comments on the text. ; acceptedVersion
