Condensation, mildew and fungi thrive in many poorly ventilated homes, leading to asthma and many other respiratory diseases. When you have a cold and humid house, you and your loved ones are exposed to poor health and therefore need a good ventilation system for your home.
In Australia, when planning a home ventilation system, there are many building code requirements that you should be aware of. For example, the Australian Building Code (BCA) states that you must have windows of equal size up to 10% of the house.
The best way to fight excess moisture in your home is by installing an appropriately designed ventilation system. Specifically, full home fans and exhaust fans are the best way to deal with moisture buildup.
Energy-powered ventilation systems are in most cases better than most natural systems because they work to get rid of moisture in the air as they are brought home. Ideally, you should try to maintain humidity levels within your home between 35% and 45%. This is the general level at which your family is more comfortable while avoiding any potential health problems caused by mold and mildew.

In general, a good home ventilation system:
- reduce air condensation and cases of weeping windows.
- reduce mould and mold spores.
- provides you with a dry home that requires less heat to heat.
- enhance security because you will not have to leave doors and windows open to bring in the air.
- get rid of dust particles, grafts and any other allergens present in the air.
- connect the air to a drier, softer and healthier in your home.
Types of ventilation
The most effective way to combat unpleasant odors, condensation and mold is by using a good quality ventilation system. Excessive moisture in your home can lead to a heavy accumulation of moisture in the walls, which can rot mold, mildew and even pests. Generally, moisture will tend to aggregate in enclosed areas and corners of the house in addition to the nearby windows and start eating away from the wood and board in your walls.
If you choose to go to a mechanical ventilation system, make sure that the ventilator unit is compliant with Australian Standards (AS) 3666.1, which deals with water systems in buildings and air handling to control microbes.
You can choose from several types of ventilation for your home, although the most important:
1. Exhaust fans
If your main area of ventilation is the kitchen or bathroom, the exhaust fans are the best choice for you. They are designed to remove odor and steam by force from these areas. It works by absorbing air from any local area of your home into ventilation vents and then transferring warm and humid air through the outdoor channel.
2. Energy Recovery Fans (ERVs)
Energy Recovery Devices Ventilators, also known as ERVs, maybe the best ventilation method for air conditioners operating in reverse cycles. This is because they can be effective for heating and cooling in space. ERVs capture moisture in the air as it is exhausted and then transported to the air inside to reduce humidity and temperature in your home.
3. Incorporation Slots
If under your home there is a creep experiencing frequent moisture, then the foundation openings may be the outlet. Humidity that lies under the floor creeping surfaces may lead to home instability, mold, damage and termites.
