BC § 1609.6.4
Net design wind positive and negative pressures (pressure and suction) for the components and cladding of buildings represent the net pressures (sum of internal and external) to be applied normal to each building surface. The net design wind positive and negative pressures shall not be less than 48 psf (12.30 kN/m 2 ), except at the corners of the building with a width equivalent to 10 percent of the building's width at its side, the net design wind negative pressure for the components and cladding shall not be less than: (i) 72 psf (3.46 kN/m 2 ) for the portion of the building between 200 feet (60 960 mm) to 300 feet (91 440 mm) height above ground and (ii) 64 psf (3.07 kN/m 2 ) for the portion of the building between 100 feet (30 480 mm) to 199 feet (60 656 mm) in height above ground.
