Table 6-3 of ASCE 7-05, or calculated using the formula:

Open terrain with scattered obstructions, grasslands, and flat open ground.

Wind pressure on roof overhangs should consider both top and bottom surface pressures.

Consult Table 1.5-1 in ASCE 7-05 to classify the building based on its occupancy and the consequences of failure. Categories range from I (low hazard to human life) to IV (essential facilities). This classification directly influences the importance factor (I) used in subsequent calculations.
