What are Whirlybirds?


Whirlybirds are ventilation systems that operate without the use of electricity. It’s an eco-friendly way to keep your home cool without using extra energy. They’re commonly used in commercial and residential properties, especially in Australia. This ventilation system is especially useful in the hot summer months when temperatures are high.


How It Works

These ventilation systems come in two designs: mechanical and wind-driven. Wind-driven varieties are most popular in Australia, as they require less maintenance and are more efficient. Turbines are installed within the system. Because the outer part of the vent is exposed at the roof, it naturally catches the wind, causing the turbines to spin.

Heat naturally rises to the top of any structure, pushing the cold air down. However, in most homes and establishments, the air gets trapped at the top part of the structure, causing the temperature to rise. Because these ventilation systems work to remove the hot air, you’re left with lower temperatures.

Where it’s Used

ThWhirlybirds is ventilation system can be installed in any structure to keep it cool. For homes, it’s highly recommended that you install them in the hottest parts of the area. This is usually the kitchen, as cooking generates a lot of heat and smoke. Thus, the system can function as both a vent and an exhaust – all in one!

If you’re trying to cool your entire home, one unit won’t be enough – especially for larger houses. It’s recommended that you get at least two to three units and spread out around the area. This is also true for business establishments, as a lot of air escapes from people coming and going in the premises. For commercial kitchens, the same number of units is recommended for the back of the house.

The Benefits

The main benefit of these ventilation systems is reduced cooling costs. It’s a natural way to lower temperatures without using electricity. You won’t have to use your air conditioner all the time during the summer months. To add to this, you’ll be helping save the environment by reducing your carbon emissions.
