Many Australians are concerned about the rising costs of energy and the environmental impact of high energy consumption. This has made passive ventilation an attractive method of maintaining quality air inside buildings at high levels of efficiency. Here is a look at passive ventilation and its benefits.
How does passive ventilation work?
Usually, the elements of passive ventilation are installed in the ridge and the eaves of the roof. The eaves are responsible for letting in fresh air, while the vents at the ridge work as the outlet.
Pressure differences between the two sides of the building facilitate the air circulation. For instance, air is drawn in where the pressure is high and drawn out from the low-pressure side.
Benefits
1. Reduced costs
Passive ventilation systems rely solely on natural forces. Unlike mechanical ventilation systems, you won’t have to use electricity for air circulation. Therefore, you will use less energy, get lower energy bills, and save more money.
2. Low maintenance
Once installed, passive ventilation requires minimal maintenance. You don’t have to worry about replacing filters or cleaning dirty ducts, which is common in mechanical ventilation systems. This will save you time, effort, and money.
3. Reduced condensation
As you have a “breathing” roof, condensation build up will be lower. This means there is less chance of mould creeping its way into your roof space, prolonging the life of your roof.
4. Cleaner air
With passive ventilation, quality air will be flowing in every part of the building at all times. It’s important to note that there’s never a remnant of stale air in the living spaces due to the efficiency of the system. The clean air ensures that the occupants are healthy, more productive, and have higher concentration levels.
5. Reduce carbon emissions
Since passive ventilation uses natural means, you will be reducing carbon emissions by embracing it. It is eco-friendly and environmentally-friendly to help you reduce your carbon footprint.
