Abrégé

An active airflow inhibiting apparatus (10) for an entranceway (4) comprising: a structure comprising one or more air mover devices (12) configured to be positioned adjacent an entranceway (4) of a building (2) and defining a passage therethrough for accessing the entranceway; an airflow sensor (20) configured to provide an output indicative of speed and direction of airflow through the entranceway or at the air mover devices (12); and a controller (18) connected to the air mover devices (12) and the airflow sensor (20); wherein the controller (18) is configured to receive the output of the airflow sensor (20) and to control an output of the air mover devices (12) based on the received output so as to generate a differential pressure across the air mover devices (12) which inhibits airflow through the entranceway.
