Passive House:
Resources and FAQs

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. 

No, any building can be built to the Passive House standard. eHaus have built a yoga studio, offices and apartments. There are also plans to build schools and commercial properties as the Passive House benefits become better understood by more. 

You can expect to pay 10-15% more than a standard home. The initial upfront investment costs are often slightly higher as a result of the planning and the high-quality components we use. However, you’ll also notice reductions in the cost of your power bills and maintenance over time.  

The answer to that is simple - yes you can! In fact, with every eHaus design we ensure that there are opening windows in every room. We also understand the great Kiwi passion to create outdoor spaces to dine and entertain that are connected to the house. So, ensuring great indoor/outdoor flow with large opening doors is second nature to our architects and designers. It also true that when you are living in an eHaus though, you probably won’t feel the need to open windows as often and here is why: 

In a code-built house people are encouraged to open the windows as it’s important that houses breathe, to ensure stale air as well as odours and moisture can dry out. But eHaus’ 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 a constant supply of warm fresh filtered air. The Mechanical Heat Recovery System also removes 98% of pollutants from the air - ideal for those who suffer asthma or allergies. 

Not at all, eHaus Passive Houses are all architecturally designed to your preferences. There is an unlimited range of external cladding options and a lot of flexibility for the shape and layout when designing and building your eHaus.  

Savings in heating and cooling energy for an eHaus Passive House is between 75-90% compared to a standard home.
