TO THIS EFFECT, SPECIALAPERTURES, WHICH STAY OPEN DURING THE SUMMER NIGHTS, ARE PROVIDED AT GROUND LEVEL AND ON THE ROOF, ALLOWING NATURAL VENTILATION. THE PAPER CONCERNS A CASE WHERE THE HIGH-MASS STAIRCASE (ALL INTERNAL DOORS CLOSED) WAS COOLED BY STACK VENTILATION. THE TEMPERATURES OF THE INFLOWING AIR, THE EXHAUST AIR, AND THE WALL WERE MEASURED AS A FUNCTION OF TIME. RESULTS ARE COMPARED WITH THOSE OF A SIMPLE DYNAMIC MODEL.
