Understanding Passive Ventilation

A lack of ventilation creates a series of highly problematic building issues, the most significant being:

• Condensation inside roofs and walls buildup resulting in damp bearers and joists - leads to rot and then makes the structure unsound.
• Mould issues - a health hazard and major problem in Australia’s climate.
• A build-up of carbon dioxide - can lead to headaches, lethargy and breathing difficulties.
• Lack of air exchange leading to temperature differentials - uncomfortable for occupants.
• Higher energy costs - people need to mitigate the above with electric or gas solutions.

Passive ventilation can assist to mitigate all of these issues.
