Atmospheric pressure at sea level averages about 14.5 psi, which is about one ton per square foot. At an elevation of 1122 feet above sea level, it averages about 0.6 psi less than that. But the pressure at any level in the building should be just about the same as the pressure outside the building at that level, unless the pressure in the building is intentionally altered.
