The present study investigates the effect of wall porosity, inlet-to-outlet-ratio (A1/A2), opening location, and blockage on internal pressure in buildings with cross-ventilation through large openings, considering data from simultaneous measurements on multiple internal pressure taps. The study found that the internal airflow field has a significant impact on mean and peak values of the internal pressure, which is not uniform for configurations with wall porosity higher than 10% and openings located on adjacent walls. Peak internal pressure coefficients were found to exceed the recommended design value for building category 3 (NBCC, 2005), for configurations with openings located above the mid-height of the building, leeward wall outlets, and A1/A2 ≥ 2.
