Why Blower Door Testing is Key for Your Home’s Energy Efficiency


A blower door test is effective in understanding your home’s energy efficiency. As Australians increasingly prioritise sustainability and reduced energy usage, this method is essential for home maintenance and improvement.

Understanding the Blower Door Test
The blower door test involves placing a robust fan into an external house door. This fan removes air from the house, creating a difference in pressure between the inside and the outside. The lower indoor pressure draws in air from outside through any existing cracks or gaps. This process allows for measuring air leaks, helping pinpoint areas where the home is losing energy.

The Value of Airtightness
An airtight home has several advantages. It makes living spaces more comfortable by reducing drafts and fluctuating temperatures. Also, it can lower energy bills by preventing the loss of heated or cooled air. Airtightness can also enhance indoor air quality by keeping out pollutants from outside.

Energy Efficiency and Its Impact
The blower door test is essential for specific certification programs, including Passive House. It’s also a crucial component of the energy rating systems that assess a building’s energy performance. One such system in Australia is the Nationwide House Energy Rating Scheme (NatHERS), which gives homes a star rating based on their potential energy use.

When Renovating Your Home
If you want to improve your home’s energy efficiency, a blower door test can provide valuable insights. The results of the test help experts suggest improvements to enhance your home’s energy efficiency and indoor air quality.

Maintaining indoor air quality can become a concern when a home is exceptionally airtight. For this, technologies like Heat Recovery Ventilators (HRV) or Energy Recovery Ventilators (ERV) are often recommended. They work to exchange stale indoor air with fresh outdoor air without significant heat or cool loss.
