Numerical simulations are compared with experimental mean values of c haracteristic pressure (Cp) values on a gable wall and on a roof over hang of a low-rise building. The inclinedwind direction investigated is normal to the gable wall. Two model designs with an overhang of 0. 3m and 3.4m are examined. The main issue with this paper is to invest igate what influe nce a large roof overhang have on the Cp-values for the house, compared with an ordinary roof.
