(57) The invention lies in the area of controlling, for example countering, transport
of moisture from the crawl space located beneath a building to the space inside that
building.
The basic cause of moisture transport from the crawl space to the house is the difference
in pressure between the crawl space and the house.
The invention proposes a method of the type referred to which comprises the following
steps:
(1) ascertaining of the pressure side (i.e. the side on which the wind is directed)
of the building, and of the suction side (i.e. the side away from the pressure side),
(2) the arranging of at least one first ventilation opening on the pressure side and
at least one second ventilation opening on the suction side, which ventilation openings
connect the crawl space with the surrounding air, and
(3) selecting of the (first) passage surface area of the first ventilation opening
and the (second) passage surface area of the second ventilation opening such that
the second passage surface area is a preselected number of times greater than the
first passage surface area.
