How Much Does It Cost To Build A Passive House?

The concept of building more sustainable and energy-efficient homes is becoming increasingly popular in Australia, so it is no surprise that clients are interested in a Passive Home design. But of course, they want to ensure it is cost-effective and suitable to their budget. Therefore, we want to tackle the question ‘how much does it cost to build a passive house?’


First of all, what is a passive house?

To summarise, a ‘PassivHaus’ is a German concept largely used in Europe but has now made its way to Australia. This concept is a form of energy-efficient building to reduce the ecological footprint of the structure. This method of construction promotes a comfortable and healthy living environment all year round.

The 5 core principles of the design are:  

  • Roof and Wall Insulation
  • High-performance windows
  • Air Tightness
  • No Thermal Bridging
  • Energy Recovery Ventilation

A series of tests are then conducted by a Passive House certifier to complete the certification process.


It is an attractive concept of a forever home; I’m sure you can agree! But how much does it all cost to achieve?

As the popularity of passive houses increases in Australia, so has the availability of materials. This increase assists with costs, as more resources are available in Australia rather than imported.

According to the Australian Passive House Association, ‘The extra cost will depend greatly upon design, size of the project, quality of finishes and so forth, but typically a range of 10 – 20% should be prepared, assuming the builder has some experience and training in this type of construction.’


A Passive House Design Is A Long-Term Investment

One of the main cost benefits of a Passive House is long-term savings. When building a Passive House, you can reduce your energy bills by up to 90%.

As energy-efficient living become popular in Australia, the ‘PassivHaus’ label attached can likely improve the homes market value.

So there you have it!
