Why do I need a Passive House in Australia?

Though it may seem easier to build a conventional Australian home, they’re significantly less environmentally friendly and tend to cost more in the long run compared to a Passive House. Following the BASIX certification standards, new homes in Australia barely meet the energy efficiency standards due to following outdated construction methods.

With insufficient insulation, uncontrolled thermal bridging and poor-quality single pane windows, this standard requires an overuse of expensive heating and cooling systems that can’t compare to the levels of comfort you’re guaranteed within a Passive House.

Will I have to source my materials internationally?

Whilst building a Passive House is renowned for using premium materials, there are a number of certified suppliers based in Australia who collaborate with Passive House consultants and architects to bring the best to your new home. By using resources that meet specific design principles and performance criteria, we can help transform your home design so that it seamlessly considers the surrounding environment and climate.

As Passive House design continues gain popularity in Australia, our chosen manufacturers allow us to work exclusively with you to select the perfect materials for your project. Our pre-construction and design stages will enable us to plan your dream home without compromise and with your budget and lifestyle at the forefront of our mind.

Aren’t Passive Houses expensive?

With a greater focus on the building’s efficiency, a Passive House is ultimately a worthwhile investment for many prospective homebuilders. As you contemplate your forward-thinking build, it’s important to consider how the energy efficiency of your Passive House can positively impact your financial circumstances. For example, the cost of creating a Passive House upfront is offset by the huge reduction in energy bills and the limited need for heavy heating and cooling systems.

It’s also important to consider how new Passive House building is in Australia. With around 200 homes across the country, costs can range between $2,500-$4,000 per square metre. As an emerging practice, there are builders who are hesitant to approach this design method as it’s grounded in forward-thinking simplicity rather than architecturally ornate custom residences.

Isn’t a Passive House a complicated, high-tech building?

If anything, a Passive House is easier to maintain and control than a conventional Australian home. The technology utilised in Passive House design is naturally user friendly and could even be compared as a higher quality version of typical building methods and mechanisms.

At its core, Passive Housing allows for easier ventilation and air-circulating technology that can be regulated by simple controls for effortless enjoyment.

Do builders need to be qualified to build a Passive House?

Building a Passive House requires meticulous planning and testing to achieve industry certification. With rigorous testing in the design and construction stages, each component of a Passive House is carefully sequenced and implemented with superior building standards.
