Reverse Stack in warm countries.

Bangkok literally has no winter, few days in one year that the ambient temperature is below 25 Celsius while air conditioning system in building is set at 25 Celsius.

95% of time the outside air is warmer than the building air, a downward airflow rationally exists in stairways and elevator shafts (reverse stack). In case of fire (in real life) smoke will flow upward or downward?

What is your experience?
