One of four conditions modifying design wind pressure according to obstructions in the area surrounding a building site. Exposure A: urban areas with high-rise buildings, or rough, hilly terrain; Exposure B: suburban sites, wooded Ares or rolling terrain; Exposure C: flat, open terrain with minimal obstructions; Exposure D: flat, unobstructed terrain facing large bodies of water. The more open a site, the greater the wind speed and the resulting design wind pressure. (Ching, 1995)
