Residential Design Pressure

design pressure

Design Pressure Calculations (DPC) is a calculation that identifies the load – induced by wind and/or static snow – a building and its openings must withstand in its end-use application. On the other hand, the manufacturer provides the Design Pressure Rating (DPR) which identifies the pressure that the window can withstand. It will tell you how well your windows or doors will stand up to high winds or heavy snow. The higher the DPR the stronger the window or door. DPR has to be equal or greater than DPC, in that way your windows /doors will be capable to support the local loads.

Exposure represents the adjustments due the characteristics of the terrain surrounding the building.

Exposure B.For buildings with a mean roof height of less than or equal to 30 feet (9144 mm), Exposure B shall apply where the ground surface roughness, as defined by Surface Roughness B, prevails in the upwind direction for a distance of at least 1,500 feet (457 m). For buildings with a mean roof height greater than 30 feet (9144 mm), Exposure B shall apply where Surface Roughness B prevails in the upwind direction for a distance of at least 2,600 feet (792 m) or 20 times the height of the building, whichever is greater.

Exposure C.Exposure C shall apply for all cases where Exposure B or D does not apply.

Exposure D.Exposure D shall apply where the ground surface roughness, as defined by Surface Roughness D, prevails in the upwind direction for a distance of at least 5,000 feet (1524 m) or 20 times the height of the building, whichever is greater. Exposure D shall also apply where the ground surface roughness immediately upwind of the site is B or C, and the site is within a distance of 600 feet (183 m) or 20 times the building height, whichever is greater, from an Exposure D condition as defined in the previous sentence.
