Enhancement of stack ventilation in hot and humid climate using a combination of roof solar collector and vertical stack

In the hot and humid climate, stack ventilation is efficient due to small temperature difference between the inside and outside of naturally ventilated buildings. Hence, solar induced ventilation is a feasible alternative in enhancing the stack ventilation. This paper aims to investigate the effecti...

The highest air temperature difference between the air inside the stack and the ambient air (Ti-To) is achieved in the semi-clear sky condition, which is about 9.9C (45.8C - 35.9C).
