Passive House

iConstruct now offers homeowners the opportunity to build a Passive House. Passive House is a certified building standard that results in the creation of high performance buildings providing a healthy and comfortable living experience, as well as being highly energy efficient. The standard was originally developed in Germany in the early 1990s, where it was known as Passivhaus. It has since spread across Europe and is only now beginning to make its way into Australia.

The Passive House standard is unparalleled in its design and quality, offering its habitants the best living experience possible. A peaceful home with stable temperatures all year round and exceptional indoor air quality is the bare minimum you can expect.

Each Passive House involves a rigorous design process that ensures it will meet the certification standard set by the Passive House Institute in Germany. With our constantly evolving environment and the climate change fight we all now are facing, it is more important than ever that Australians live and work in the most healthy, comfortable and energy efficient buildings as possible.

Implementing the Passive House principles into the building of your home is a scientifically proven way of guaranteeing savings of up to 90% in energy usage, which will result in huge reductions in energy bills. With its constant flow of fresh, filtered air and the extraction of the stale, odorous air, Passive House is the only way to build going into the future.

Those 5 key building principles on which Passive House is measured are:


  • Thermal Insulation – A continuous and complete thermally insulated building envelope ensures internal temperatures are kept comfortable and regulated 365 days per year
  • High Performance Windows – Double or triple glazed windows help maintain internal temperatures and form part of the thermal barrier
  • Airtightness – An airtight building envelope ensures the heat energy within the home is contained and doesn’t leak through any gaps, vital in keeping stable temperatures year round.  A blower door test is performed to measure the amount of air leaks and whether it meets certification standard
  • Thermal Bridge Free – The term “Thermal Bridge” can be described as a highway in which heat can travel in and out of your building. They can occur at window openings, changes of direction in the building and where different materials connect. Keeping these to a minimum will reduce the risk of mould and condensation, whilst also helping in stabilise temperatures and reducing the energy consumption
  • Heat Recovery Ventilation (HRV)  – This mechanical system allows for fresh, filtered air to circulate in the building whilst extracting all the un-healthy air. Also acting as a heat exchanger, no matter the external climate, it will regulate the air to the required internal temperature
