PERFORMANCE OVERVIEW

Discover the difference between our eHaus performance options.

The eHaus Pacific is our high-performance standard

About This Performance Standard

The eHaus Pacific is also designed to maintain a temperature range of 20–25°C, using up to 50kWh per m² annually for heating. The thermal performance of the eHaus Pacific is reduced slightly compared to the eHaus Euro.

What's Different?

An eHaus Pacific requires some additional heating or cooling to keep a comfortable temperature all year round. The eHaus Pacific has a lowered threshold on performance compared to an eHaus Euro but still eclipses a typical NZ standard code-built home. It is a smart, efficient choice that offers more flexibility when it comes to design.  

The Certification

Though they don’t meet the stringent Passive House criteria, our eHaus Pacific homes are energy modelled and undergo rigorous internal checks and processes and are awarded eHaus verification upon completion, following a final airtightness test for draughts.

The eHaus Euro is our premium performance standard

About This Performance Standard

The eHaus Euro is our gold standard when it comes to energy performance. It’s built to keep your home between 20–25°C all year round, using just 15-30kWh per m² of energy annually for heating. There are no thermal gaps, just a continuous wrap of insulation that keeps the warmth in and the cold out. 

What's Different?

With a very low need for any additional heating or cooling, your home stays comfortable no matter the season. You’ll feel the difference and notice it in your power bill too. The eHaus Euro sets a higher performance threshold than the eHaus Pacific. Similarly, it is not Passive House Certified.

Though they don’t meet the stringent Passive House criteria, our eHaus Euro homes still undergo rigorous internal checks and processes and are awarded eHaus verification upon completion, following a final airtightness test for draughts.

Set by the International Passive House Institute

About This Performance Standard

Passive House is a globally recognised certification that proves your home is designed and built to some of the world’s most stringent energy standards. 

What's Different?

Certification provides a level of assurance that your home will perform to the Passive House standard, which guarantees high energy savings, a healthy living environment and can even increase your home’s market value. 

The Certification

There are several stages to Passive House certification. During the planning and the design stages, your plans are submitted for independent review. Post-construction the Certifier will conduct a thorough review, which includes airtightness test verification, and verification of systems such as heating and ventilation. The price for a family home ranges from $8,000 to $12,000.

The Everyday Difference

Taking a closer look at our eHaus Euro, eHaus Pacific and Passive House performance standards can help you find the perfect fit. Here, you can get an idea of how comfortable each standard is and how much less energy you'll need each year.

Comfort Energy Use

eHaus Pacific

The eHaus Pacific still gives you a comfy, healthy, energy-efficient home, but you may need a bit more heating than an eHaus Euro on really cold days or use active cooling in the summer. 

An eHaus Pacific uses, on average, 82% less energy for heating and cooling compared to conventional homes.

eHaus Euro
The main thing you’ll notice in an eHaus Euro is that you will feel comfortable, even when it’s freezing outside. Most eHaus Euro homes stay at a comfortable temperature with the warmth from the sun, people and appliances. On cold winter days you may need to use the heating for a few hours to bring your home up to temperature.

An eHaus Euro uses, on average, 88% less energy for heating and cooling compared to conventional homes. The eHaus Euro uses less total energy compared to an eHaus Pacific, for heating and cooling, which keeps your power bills incredibly low.

Passive House

A certified Passive House keeps your home at a comfortable temperature in winter and cool in summer and uses very little heat energy to stay warm. Our highest-performing certified Passive House has achieved 96% savings in heating energy demand.

A Certified Passive House uses, on average, 90% less energy for heating and cooling compared to conventional homes.
