What is a Passive House NZ?
Passive House (or PassivHaus) is a low energy standard for buildings that minimises energy use and maximises comfort and affordability.
What is the most energy-efficient house to build?
Dome-shaped homes are the most energy-efficient since they have fewer corners. This allows wind to travel over the home easily without air pressure changes, which all in all reduces air penetration and thus maintains a more even temperature. Cube-shaped homes are another good option.
How many passive homes are there in NZ?

How do you build a zero energy home?
7 Steps to Building a “Net Zero” Energy Home
- Sealing and Insulating. Thoroughly sealing the envelope is the first step in crafting a net-zero home that’s protected against air and moisture intrusion.
- Continuous Ventilation.

How do you get zero energy building?
There are three principles to achieve a good net-zero energy building design:
- Building envelope measures. Not only the building should be oriented to minimize HVAC loads, but shades and overhangs should be used to reduce the direct sunrays.
- Energy efficiency measures.
- Renewable energy measures.
