Passive Ventilation Systems
Passive ventilation systems ensure that fresh air continues to circulate in your home, creating a comfortable environment. ArchiPro has selected high-quality, durable passive ventilation systems from trusted suppliers available here in Australia. With a selection of premium wall and ceiling vents, you’ll find many options for exactly what you need.
What is the difference between active and passive ventilation?
Active Ventilation refers to ventilation systems that rely on mechanical means to circulate air throughout a space. These systems typically include components like electric fans, blowers, and electronically-controlled vents that actively push stale air out and draw fresh air in. In Australia, such systems are often crucial in regions with extreme weather conditions, as they can be integrated with heating, ventilation, and air conditioning (HVAC) systems to maintain a comfortable indoor climate year-round.
Active systems are especially beneficial in tightly sealed homes where natural air flow might be minimal due to energy-efficient design. They are also key in specific areas such as kitchens or bathrooms, where moisture and odours are prevalent and need to be mechanically extracted to prevent mould growth and maintain indoor air quality.
Passive Ventilation, in contrast, utilises the natural flow of air without the assistance of mechanical devices. Australian homes designed with passive ventilation incorporate architectural features that promote the natural movement of air — these can include strategically placed windows, vents, and other openings that align with prevailing winds and exploit thermal buoyancy (warm air rising).
The advantage of passive systems lies in their energy efficiency and sustainability, as they harness natural forces without consuming electricity. However, their effectiveness can be influenced by local climate, building orientation, and external factors such as nearby buildings or natural landscapes that might obstruct air flow.
