Ridge vents power fans traditional electric and solar powered wind turbines gable louvers and roof louvers. Location on the building envelope. 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.

Pressure coefficients are tabulated for various shapes of roof flat monopitch duo pitch and hipped for a range of roof slopes. Used for roof overhang area along the perimeter of zone 3. Used for roof overhang area along the perimeter of zone 2. Because they will be in the same wind pressure zone working together.

The wind pressure acting on a building face is the product of the dynamic pressure 0 5 x air density x wind speed2 and a pressure coefficient obtained from the design standard. The shidy is initiated by the discrepancies fomd in recent research. For flat roofs roof angle 0 degrees either gable or monoslope may be used. Any areas between the wall corners that are not included within zone 5.
