Experimental analysis of natural ventilation of an office building in Mexico city

An experiment is described to evaluate natural ventilation in a ten-story office building in Mexico City. The airflow results from the flotation of the internal hot air when the outside environment is colder. The objective of this work is to establish basic design considerations for effective ventil...
