Application
Application 1: 
Formula for the calculation of specified wind pressure or suction on exterior surfaces of buildings to be used in the calculation of specified load due to wind.
This applies to buildings described in Sentence 1.3.3.2.(1) of Division A and to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] that are required to be designed in accordance with the requirements of Part 4.

Intent
Intent 1: 
To limit the probability that the calculation of specified wind pressure or suction on exterior surfaces of buildings will not take into account all the factors that affect the expected maximum magnitude and distribution of wind pressure and suction on the exterior surfaces of buildings, which could lead to structural failure, which could lead to harm to persons.
Intent 2: 
To limit the probability that the calculation of wind load used for the design will not take into account the level of reliability appropriate for the use and occupancy, which could lead to structural failure, which could lead to harm to persons.
