The purpose of this paper is to report the foundmental data for the pressure loss at the openning of wall surface when wind flows near the wall surface. In this paper, we describe the wind tunnel invesitigation into the property of the pressure loss at the openning of wall surface of model in a simulated atomospheric boundary layer. The results are surmmarized as follows. 1) With increasing of down-flow near the wall surface, the pressure loss at the openning of wall surface gets bigger as the thickness of turbulent boundary layer gets thinner. 2) When a low model is placed upwind of tall model, with increasing of wall wind pressure, the pressure loss at the openning of wall surface gets smaller and with increasing of down-flow near the wall surface, the pressure loss at the openning of wall surface gets bigger. 3) The correlation between the pressure loss at the openning of wall surface and mean wind velocity near the wall surface is observed. 4) The correlation between the pressure loss at the openning of wall surface and the wall wind pressure is observed.
