• maintaining a vertical distance between two openings to create a stack effect, i.e. hot air rising and
thereby enhancing air flow
• shafts to promote air flow
• maximising air flow by designing open plan spaces
• maximising air flow by having openings at different levels or near the ceiling on opposite sides of the
space
• using architectural and landscape features to direct and control air flow - for example, using casement
sashe on the windward façade as these can be more efficient than other types of sashe, and including
opening windows on the leeward face.
In tropical parts of Australia,it is common practice to install louvre window to provide good air flow
control as well as keeping rain out. Louvre are also fairly common in warmer, more humid parts of New
Zealand.
