Has the highest load.
The roof zones come into play when designing how a solar system will attach to the roof.
For example the edges of a roof are subjected to higher pressures than the centre so may require additional fasteners.

In order for a structure to be sound and secure the foundation roof and walls must be strong and wind resistant.
Location on the building envelope the wind pressure varies with location on the building envelope.
The present wind tunnel study examines the suitability of the current wind provisions in wind codes and standards for the design of roof zones of flat roofed low rise buildings with large dimensions.
Large buildings say 100 m long have not been considered when these provisions were.
When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds especially if the building is located in an area known for inclement weather.
