Natural ventilation is the process of supplying and removing air through an indoor space by natural passive means. For comfort and saving energy, there are two major types of natural ventilation occurring in buildings: wind driven ventilation and stack ventilation. The majority of buildings employing natural ventilation rely primarily on wind driven ventilation, but stack ventilation has several benefits and doesn’t need wind pressure for removing hot air. The most efficient design for a natural ventilation building should implement both types of ventilation but there is not enough wind pressure in Malaysia that’s why in this project just relies on a stack effect. Three time measurements accomplished on this project in three different conditions which includes stack effect and interference fan on the stack for harnessing more results and accelerating ventilation.
