The properties of internal pressures induced by wind are very important for evaluating the wind loads of exterior materials and structural frames in buildings. This paper describes the properties of internal pressure in nominally sealed but leaky low-rise buildings induced by wind. The internal pressures in the low-rise building models with the apertures are measured in a wind tunnel experiment. The internal pressure fluctuations in the nominally sealed but leaky low-rise buildings have also been simulated using the leak-flow model and the fluctuating external pressures obtained from the wind tunnel experiment. The relationship between external pressures and internal pressures in the low-rise building models with the apertures are also shown by normalized power spectra, coherence and phase spectra.
