We have performed Large-Eddy Simulation of flow and pressure fields over two types of urban-like block arrays in order to investigate the relationships between instantaneous building wall pressure and surrounding flow fields. The adopted block arrays are: lattice-type square and staggered pattern. The analysis on the distributions of statistics for wall pressure shows that the large values of the statistics are observed along with the top and side edges of the wall for the square array, whereas they are shown on an upper half region of the wall for the staggered array. These large values are due to air flow introduction from both above and side of the target block for square array; in contrast, strong flows introduced into canopy area cause large pressures of the upper half of the wall for staggered array.
