Abstract
The invention relates to a sliding door with two outer side-pieces extending from a building wall and surrounding a building entrance/exit, with at least one moving panel associated with the two side-pieces which closes or opens an entrance/exit as a result of its movement into a closed or open position, and with a ventilation system which, by means of at least one blower nozzle that is located so that it can pivot between the interior and exterior of the building, blows air into the building entrance/exit area, whereby the blower nozzle is coupled with a air speed indicator so that the pivoting angle of the blower nozzle can be adjusted as a function of the outside pressure on the outside of the building as measured by the air speed indicator.
