Curious to learn more about the Passive House standard and what sets it apart from regular building standards? Start with our FAQs below and contact us if you have any further questions.
Passive House is an internationally recognised building standard that delivers a building that requires very little energy for space heating or cooling. The result is a home that provides a warm and comfortable living environment. The temperature is even throughout the home and operates typically between 20 and 25 degrees, while consuming minimal energy. Passive Houses consume between 75%-90% less heating energy than a conventional house.
In some cases, it is possible that it is the same cost, but for an individually designed residential home typically the benchmark cost is 10-15% more than a standard home. The square metre rate is difficult for us to provide for building a Passive House, as the local climate region and individual design specifications and other key considerations have a big impact on the final cost.
Passive Houses are built to a higher standard and perform at a higher international certified standard than a code build. As such, the initial upfront investment costs are often slightly higher as a result of the more intensive planning and superior components involved. However this is soon realised over the lifespan of the building due to the extremely efficient performance and incredible low running costs. Also due to the high quality of the build the maintenance of the building is lower e.g. no condensation and mould to damage the internal fabric of the home, saving on maintenance time and money.
The answer to that is Yes can!
In a Passive House though, you probably won’t feel the need to do so and it is not necessary throughout most of the year. In a code build house people are encouraged to open the windows as it’s important that houses breathe and also to ensure stale air as well as odours and moisture can dry out. But Passive Houses are different. The ventilation system provides constant high quality indoor air, automatically removing moisture and ensuring all year round comfort. The result is a space that has no draughts, and a constant supply of warm fresh filtered air. The Mechanical heat recovery system also removed 98% of pollutants from the air - ideal for those who suffer from asthma or allergies.
We also recommend having your eHaus Passive House independently certified, this provides you the assurance that all the Passive House criteria have been met.
The clever part is in each climate region the internal comfort and consumption of energy is the same. Whether your eHaus Passive House is in Northland in the middle of Summer, or Southland in the middle of Winter, the internal temperature of every room stays between 20 – 25 degrees. Providing you with a healthy, warm and comfortable environment for your family to live.
