... in the classrooms and stacks were calculated. It was found that the airflow through the passive stacks was a significant proportion of the classroom air exchange rate and metabolic CO 2 was lower in classrooms with passive stacks. The predictions of a multi-zone airflow computer model were compared with measured...

.... In particular, the paper focuses on the south façade passive stacks and their relative contribution to cooling through increased ventilation. It was found that due to the relatively narrow plan of the building, the cross-ventilation flow paths could satisfy most of the summer cooling ventilation requirements...
