Wind exposure. Design wind pressures and their applicable.

These tests established that the zoning for the roof on these low-slope roof structures was heavily dependent on the building height, h, and much less dependent on the plan dimensions of the building. Wind exposure.

For example, in Denver, CO, the Mile High City, the ground elevation factor, Ke, is 0.82 which translates to an 18% reduction in design wind pressures.

This reduction was provided in the Commentary of previous editions of the Standard; however, it is being brought into the body of the Standard to facilitate its use.
