Wind increases the external pressure on windward walls, and decreases it on side and leeward walls. The walls have leakage paths through which air flows either in or out, depending on whether the internal pressure is lower or higher than the external pressure. Internal pressure adjusts to make inflow equal outflow, and depend on the size and location of large openings as well as the "background" leakage and the external pressure distribution. A program, originally written to compute air infiltration, was used to predict the internal pressure for a 56-story building. The analysis showed that the addition of a single opening the size of a typical window may cause as much as a 60 percent increase in the time-averaged maximum cladding pressure,...
