Pressure rise in some buildings caused by gusty wind. Druckansteig im inneren von Gebauden bei Windeinfall.

Considers the rise in air pressure inside a closed building with openings on the windward side, caused by gusts of wind and the increased pressure on the building envelope, especially on the roof. Derives expressions for the transient pressure inside the building, dependent on the velocity of the wind, the volume of the building and the size of openings on the windward side. Notes that in general buildings are more permeable than has been assumed
