The roof panel structure is a new structure used for heat isolation on building roofs. This paper describes a parametric wind tunnel study that investigated the effects of porosity on net pressures on this structure. The propagation of pressures was studied through models to determine the effects of porosity. The mean, fluctuating (RMS), maximum peak and minimum peak distributions over the surfaces of the roof panel were measured for porosities of 0%, 5% and 10% (ratio between area of orifices and area of roof panel). The results show that the roof panel with no porosity (0%) had the highest net pressures. Those with porosities of 5% and 10% were most effective in reducing pressure fluctuations without significantly increasing mean pressures.
