What we do

Te Tōpūtanga o te Whare Korou ki Aotearoa, Passive House Institute NZ (PHINZ) is on a mission to close the gap between the desired and actual performance of buildings and to accelerate the delivery of measurable and continuous improvements in their indoor environmental quality in tandem with their energy-efficiency. We work with professionals and the public sector to improve the energy efficiency of homes and public buildings, helping improve health and well-being, and relieving fuel poverty for New Zealanders.


We educate the building industry and members of the public about Certified Passive Houses and improved energy efficiency and indoor environmental quality in New Zealand buildings.

Formal Passive House training is provided through Passive House Academy NZ, a PHINZ project.


We share our research on the performance of built Certified Passive Houses in New Zealand, on the New Zealand climate and on housing industry in order to promote energy efficient building options.


We promote the Passive House Standard, as defined by the Passivhaus Institut, Germany, in Aotearoa/New Zealand.
